Georgia Medicare Grievances: Complaint Process Guide

::: hero

By Brevy Care Team · Last verified May 13, 2026

When a Medicare Advantage plan keeps you on hold for forty-five minutes, when a sales agent misrepresents what the plan covers, when the hospital tries to discharge you while you still feel acutely ill, when your closest in-network pharmacy is thirty miles away, or when your primary care office staff treats you with contempt, the law gives you a distinct procedural tool to demand a written response and trigger oversight. That tool is the grievance, and it is one of the most underused beneficiary protections in the entire Medicare program. Section 1852(f) of the Social Security Act requires every Medicare Advantage plan in the country to maintain a meaningful grievance process for complaints that are not coverage or payment denials. Section 1860D-4(f) imposes the parallel requirement on Medicare Part D prescription drug plans. The implementing regulations at 42 CFR 422.564 and 42 CFR 423.564 establish a 30-day plan response standard, an expedited 24-hour standard for certain time-sensitive complaints, and a documentation and CMS reporting obligation that feeds the Star Ratings complaint measures. For quality of care concerns, Section 1154 of the Social Security Act creates the federally contracted Quality Improvement Organization network, and KEPRO is Georgia's QIO contractor. Yet most Georgia Medicare beneficiaries who experience a plan service failure either never file a grievance, or file one without understanding the federal framework that gives them leverage. This guide explains the statutory authority for grievances, the regulatory standards that govern them, the critical distinction between grievances and appeals, the nine grievance categories CMS recognizes, the role of KEPRO for quality of care issues, the parallel pathway to complain to CMS through 1-800-MEDICARE, the Georgia Department of Insurance role for marketing and operations complaints, and six worked examples for typical Georgia grievance scenarios. :::

Key Takeaways for Georgia Medicare Beneficiaries

• Grievances differ from appeals. An appeal challenges a coverage or payment denial (Adverse Benefit Determination) and moves through a five-level federal process. A grievance addresses anything that is not a coverage or payment denial. Filing the wrong type of complaint can cost weeks of resolution time.
• The 30-day response standard is the legal default. The plan must respond within 30 days of receiving the grievance. The plan may extend by up to 14 days if the extension is in the enrollee's best interest, with written notice of the delay.
• File with KEPRO in parallel for quality of care issues. Georgia beneficiaries can contact KEPRO, the state's federally contracted Quality Improvement Organization, simultaneously with filing a plan grievance for independent physician-level medical review. The plan cannot prevent or discourage a beneficiary from filing with KEPRO.
• Complaints feed CMS Star Ratings. Plans report aggregated grievance data to CMS, which feeds complaint measures that are heavily weighted in the Star Ratings calculation. Filing a grievance is both an individual remedy and a systemic accountability mechanism.
• Multiple agencies have jurisdiction. Beyond the plan: CMS via 1-800-MEDICARE, the Georgia Department of Insurance, HHS Office of Civil Rights, and the HHS Inspector General each handle different aspects of Medicare complaints. :::

Section 1852(f) of the Social Security Act: The Federal Grievance Mandate

Section 1852(f) of the Social Security Act is the statutory foundation for every Medicare Advantage grievance procedure in the United States. The provision was added when Congress created the Medicare+Choice program that later became Medicare Advantage. The Section 1852(f) text directs that each Medicare Advantage organization shall provide meaningful procedures for hearing and resolving grievances between the organization (including any entity or individual through which the organization provides health care services) and enrollees. The statute is intentionally broad. Congress did not enumerate which complaints qualify. Instead, Congress directed the Secretary of Health and Human Services through the Centers for Medicare and Medicaid Services to implement the procedural standards through regulation. CMS did so at 42 CFR 422.564, which establishes the actual operating rules.

Section 1860D-4(f) of the Social Security Act extends the same framework to Medicare Part D prescription drug plans. The Medicare Modernization Act of 2003 created Part D and built grievance procedures into the structural design of the benefit. The Part D implementing regulation at 42 CFR 423.564 is substantively parallel to the Medicare Advantage regulation. A Medicare Advantage Prescription Drug plan (MA-PD) must operate both grievance processes through a unified beneficiary-facing system, though the regulatory authority for the drug benefit portion runs through Part 423.

The federal statute creates several legally enforceable obligations. First, every Medicare Advantage and Part D plan must have a grievance procedure available to all enrollees from the moment of enrollment. Second, the plan must respond to a grievance within a specified time period. Third, the plan must document the grievance and its resolution and report aggregated data to CMS. Fourth, when a grievance involves quality of care, the plan must inform the beneficiary that the complaint may also be filed with the state Quality Improvement Organization, which for Georgia is KEPRO. Fifth, the plan cannot retaliate against an enrollee for filing a grievance and cannot use grievance filings against the enrollee in coverage determinations.

Section 1154 of the Social Security Act, the Quality Improvement Organization statute, complements the grievance framework. Section 1154 creates the federally contracted QIO network that handles quality of care complaints, hospital discharge appeals, and immediate advocacy for Medicare beneficiaries. The QIO is independent of the Medicare Advantage plan and acts as a neutral medical reviewer when a beneficiary believes the care received was substandard. For Georgia, the contracted QIO is KEPRO. The QIO handles complaints across both Original Medicare and Medicare Advantage, but in the Medicare Advantage context, the QIO process operates alongside the plan grievance process, not as a substitute for it.

Grievances Versus Appeals: The Critical Procedural Distinction

The single most important concept in the Medicare complaint framework is the procedural distinction between a grievance and an appeal. The two terms are not synonyms. They invoke different statutory authorities, different regulatory timelines, different evidentiary standards, and different escalation pathways. Understanding which type of complaint to file determines whether a beneficiary gets the right outcome on the right timeline.

An appeal is the proper mechanism when a Medicare Advantage or Part D plan has issued an Adverse Benefit Determination. An Adverse Benefit Determination is defined at 42 CFR 422.566(b) for Medicare Advantage and 42 CFR 423.566(b) for Part D, and it covers situations such as: denial of payment for services already received; denial of authorization for services not yet received; failure to provide services in a timely manner; failure of the plan to act within the timeframes required for organization or coverage determinations; denial of formulary coverage for a drug; denial of a request to lower the cost-sharing tier for a drug; denial of a request for an exception to a step therapy or quantity limit rule; reduction or termination of a previously authorized course of treatment. Anything in this category triggers the five-level Medicare appeals process: Level 1 (Plan Redetermination or Reconsideration), Level 2 (Independent Review Entity for both MA and Part D), Level 3 (Office of Medicare Hearings and Appeals administrative law judge), Level 4 (Medicare Appeals Council), Level 5 (Federal District Court). Each level has its own filing deadline and procedural rules. For a comprehensive treatment of the appeals process, see Brevy's separate guide at /medicaid/georgia/medicare-appeals-process.

A grievance is the proper mechanism for any complaint that is not an Adverse Benefit Determination. This is the broader category. CMS guidance at Chapter 13 of the Medicare Managed Care Manual identifies the typical grievance categories. The plan held you on the phone for forty-five minutes before answering: customer service grievance. A sales agent told you the plan covered dental implants when in fact it did not: marketing complaint, which is also reportable to the Georgia Department of Insurance. The plan took eleven days to process a routine prior authorization request even though the request was eventually approved: prior authorization timeliness grievance, which is a grievance against the operational delay, not an appeal against a denial because the request was approved. Your primary care physician's office staff was rude and the office was visibly unsanitary: provider conduct grievance. You believe the hospital discharged you too soon and you experienced complications at home: quality of care grievance, which should also be filed with KEPRO. The plan sent your member ID card to the wrong address despite three address-correction requests: plan operations grievance. The nearest in-network pharmacy is thirty miles from your home and there is no pharmacy within a reasonable distance: pharmacy network adequacy grievance.

The procedural distinction matters because the timelines differ. The plan-level appeal (Level 1 reconsideration) must be decided within 30 days for a standard pre-service request, 7 days for a Part D pre-service request, 60 days for a payment request, and 72 hours for expedited situations. The grievance must be resolved within 30 days. Crucially, the standard remedies differ. An appeal that is granted requires the plan to authorize or pay for the disputed service. A grievance that is granted requires the plan to issue a written response acknowledging the complaint, describing any corrective action taken, and documenting the resolution. A grievance generally does not order monetary or service relief because the grievance is not about whether a benefit was wrongly denied. The grievance is about whether the plan operated correctly. If the plan operated incorrectly in a way that caused a benefit denial, that situation requires both a grievance (about the operational failure) and an appeal (about the wrong denial).

The escalation pathways also differ. An appeal escalates through the five federal levels. A grievance does not have a federal escalation process. The plan's grievance decision is the plan's final word at the plan level. However, a beneficiary dissatisfied with a plan grievance response is not without options. The beneficiary can file a parallel complaint with CMS through 1-800-MEDICARE, contact the Georgia Department of Insurance, refer the matter to KEPRO if it involves quality of care, or in some cases file with HHS Office of Civil Rights if the issue involves discrimination on a protected basis.

The grievance and the appeal are not mutually exclusive. A beneficiary can and often should file both when both apply. For example, a beneficiary whose prior authorization request was denied, and who experienced an eleven-day delay before receiving the denial, has both an appeal (against the denial itself) and a grievance (against the procedural delay). Filing only the appeal leaves the operational failure unredressed; filing only the grievance leaves the denial in place.

The Nine Grievance Categories

CMS recognizes nine substantive grievance categories in the Medicare Managed Care Manual Chapter 13. These categories define what types of complaints qualify as grievances and what plans must report to CMS.

Customer service complaints cover any beneficiary experience with plan call centers, member services representatives, written correspondence, online portals, and any other interaction with plan staff. Examples include long phone hold times (any hold time over the plan's published service standard), unreturned voicemails, rude or dismissive representatives, incorrect information provided by representatives that leads the beneficiary to make a wrong decision, failure to respond to written correspondence within reasonable timeframes, and inaccessible portal functions for beneficiaries with disabilities. The plan must document and resolve customer service grievances within 30 days, and CMS tracks these as a Star Ratings measure.

Marketing and enrollment complaints address sales agent or broker conduct, plan marketing materials, and enrollment process problems. Examples include a sales agent who misrepresents benefits or premiums, who fails to provide a Summary of Benefits, who uses high-pressure tactics, who enrolls a beneficiary in a plan without the beneficiary's clear consent, who fails to disclose plan limitations or network restrictions, who provides information in a language the beneficiary does not understand without offering interpretation services, or who solicits in unapproved locations. Marketing complaints are doubly actionable because they can be filed both with the plan as a grievance and with the Georgia Department of Insurance, which has independent regulatory authority over agent licensing. Recent CMS rulemakings strengthened marketing oversight in response to a surge in marketing complaints.

Provider conduct complaints address the behavior of network providers, including primary care physicians, specialists, hospital staff, pharmacy staff, and ancillary providers. Examples include a provider who is rude or unprofessional, a provider office with unsanitary conditions, a provider who refuses to see a beneficiary for non-medical reasons, a provider who repeatedly cancels appointments, a provider who fails to coordinate care appropriately, or a provider who pressures a beneficiary on personal or political matters. Provider conduct complaints can also be referred to the Georgia Composite Medical Board for medical license issues or to KEPRO if the conduct rises to the level of quality of care concerns.

Quality of care complaints are the most consequential grievance category because they trigger parallel KEPRO review under Section 1154 of the Social Security Act. Examples include inadequate hospital care, premature hospital discharge while the beneficiary is still acutely ill (which also triggers an Important Message from Medicare appeal right), inadequate skilled nursing facility care, inadequate home health services, inadequate hospice services, medication errors, surgical errors, hospital-acquired infections, failure to diagnose conditions in a timely manner, failure to follow accepted medical standards, and delayed appointments that result in clinical deterioration. KEPRO is the federally contracted QIO for Georgia and conducts physician-level medical review of these complaints. The KEPRO process operates independently of the plan grievance process. The beneficiary can file with both simultaneously.

Pharmacy and drug benefit operations complaints address the operational aspects of the Part D benefit, separate from coverage determinations. Examples include pharmacy network adequacy failures (no in-network pharmacy within a reasonable distance), refill timing problems, prior authorization delays for prescription drugs, mail order pharmacy problems, transition fill failures (when a new enrollee is entitled to a transition fill for a non-formulary drug but the pharmacy refuses), formulary communication problems, and step therapy enforcement errors. These are grievances when they involve operational failures; they become appeals when they involve actual coverage denials.

Plan operations complaints cover the administrative aspects of plan operations not covered by other categories. Examples include incorrect ID card information, late ID card delivery, incorrect address information that affects mailings, billing statement errors, premium payment processing errors, Explanation of Benefits accuracy problems, late or incorrect formulary mailings, and Annual Notice of Change problems. Many beneficiaries experience plan operations issues but do not file grievances because the issues feel minor. CMS Star Ratings nonetheless track these complaints, and aggregated patterns reveal plans with weak operational discipline.

Prior authorization timeliness complaints address operational delays in plan response to prior authorization requests. Medicare Advantage plans must process prior authorization requests within regulatory timeliness standards. If the plan exceeds these timeframes but eventually approves the request, the situation is a grievance against the timeliness failure, not an appeal because the request was ultimately granted. If the plan denies the request after a delay, the situation requires both a grievance (against the timeliness failure) and an appeal (against the denial). A recent CMS rulemaking, effective plan year 2026, strengthened prior authorization timeliness requirements and gave CMS additional enforcement authority.

Marketing material accuracy complaints address inaccurate or misleading information in plan-issued written materials, advertisements, websites, and broadcast communications. Examples include a brochure that overstates benefits, a website that lists providers as in-network who have actually left the network, a television ad that misrepresents premiums, a Summary of Benefits that omits material limitations, or an Annual Notice of Change that fails to disclose a benefit reduction. These complaints are reportable to CMS and to the Georgia Department of Insurance.

Discrimination complaints address adverse treatment by the plan or providers on a basis protected by federal civil rights law. Section 1557 of the Affordable Care Act prohibits discrimination on the basis of race, color, national origin, sex, age, or disability by any health program or activity receiving federal funds, which includes every Medicare Advantage and Part D plan. Examples include refusal to provide language services to a beneficiary who speaks limited English, refusal to provide auxiliary aids to a beneficiary with a hearing impairment, refusal to make reasonable modifications to policies for a beneficiary with a disability, and disparate treatment based on national origin. Discrimination complaints can be filed with the plan as grievances, with the HHS Office of Civil Rights, and potentially with the Georgia Commission on Equal Opportunity.

The 30-Day Response Standard and Expedited Grievances

The federal regulation at 42 CFR 422.564 establishes the operational rules every Medicare Advantage plan must follow when handling a grievance. The parallel rule at 42 CFR 423.564 governs Part D grievances. Plans must adopt and implement procedures that include the following elements.

The 30-day standard response timeline. Under 42 CFR 422.564, the plan must notify the enrollee of its decision as expeditiously as the enrollee's case requires, but no later than 30 days from the receipt of the grievance. The plan may extend the response period by up to 14 days if the extension is in the best interest of the enrollee (for example, if the plan needs additional information from the enrollee or a third party to investigate the complaint). If the plan extends the timeline, it must notify the enrollee in writing of the reason for the delay and the new expected response date.

Acknowledgment of receipt. While the regulation does not specify a separate acknowledgment timeline distinct from the resolution timeline, CMS guidance and most plan operating procedures require acknowledgment within five business days. The acknowledgment should confirm receipt of the grievance, identify the case reference number, identify the staff member or department handling the grievance, and provide contact information for follow-up.

Written response requirement. The plan must provide a written response to the enrollee describing the resolution of the grievance, the basis for the resolution, and any corrective action the plan has taken or will take. Even when the grievance is filed orally, the plan must provide a written response if the enrollee requests one. CMS strongly encourages plans to provide written responses regardless of how the grievance was filed.

Expedited 24-hour grievance. Under 42 CFR 422.564, the plan must establish and maintain an expedited grievance procedure for one specific situation: when the enrollee has requested an expedited organization determination or expedited appeal and the plan has refused to grant the expedited request. The grievance must be resolved within 24 hours of receipt. The expedited grievance is also available when the plan attempts to apply the 14-day extension to an organization determination or appeal and the enrollee disagrees with the extension. This is a narrowly defined expedited category. Most quality of care or operational grievances do not qualify for the 24-hour expedited standard.

Filing methods. The enrollee can file a grievance orally (typically by phone), in writing (typically by mail or fax), or in person at the plan's local office if one exists. Some plans accept electronic filing through online portals. The plan cannot require a specific filing format and cannot impose form requirements that effectively block oral or simple written filings.

Documentation and reporting. The plan must document each grievance, the resolution, and any corrective action. Plans must report aggregated grievance data to CMS through the Health Plan Management System (HPMS), and the data feeds CMS Star Ratings complaint measures.

Authorized representatives. The enrollee can designate an authorized representative to file the grievance and receive responses. The representative may be a family member, an attorney, a State Health Insurance Assistance Program (SHIP) counselor (GeorgiaCares in Georgia), or any other person designated in writing under 42 CFR 422.561. Plans must accept grievances filed by authorized representatives.

No retaliation. Under both the federal regulations and CMS marketing rules, plans cannot retaliate against enrollees for filing grievances and cannot use grievance filings against the enrollee in coverage decisions, formulary tier assignments, or any other plan operation.

KEPRO: Georgia's Quality Improvement Organization

Section 1154 of the Social Security Act, originally enacted as part of the Peer Review Improvement Act of 1982 and updated by subsequent statutes, creates the federally contracted Quality Improvement Organization (QIO) network. CMS contracts with QIOs to provide independent medical review of beneficiary quality of care complaints, hospital discharge appeals, skilled nursing facility discharge appeals, home health and hospice discharge appeals, and Beneficiary and Family Centered Care (BFCC) services across both Original Medicare and Medicare Advantage.

For Georgia, the federally contracted QIO is KEPRO, which serves multiple states across the southeastern United States. The KEPRO process operates independently of the Medicare Advantage plan grievance process, and beneficiaries can use both channels simultaneously. The plan grievance process produces a plan-level resolution. The KEPRO process produces a physician-conducted medical review with a separate written decision.

KEPRO handles four main categories of beneficiary services. Quality of care complaints allow Medicare beneficiaries to request an independent review of the quality of care they received from any Medicare-participating provider, including hospitals, doctors, skilled nursing facilities, home health agencies, hospices, and ambulatory surgical centers. KEPRO physicians review the medical record and determine whether the care met generally accepted standards. If KEPRO finds substandard care, KEPRO reports the finding to the provider, may refer the case for further action, and notifies the beneficiary of the finding.

Hospital discharge appeals allow a Medicare beneficiary to challenge an inpatient hospital discharge the beneficiary believes is premature. Under federal regulations, every hospitalized Medicare beneficiary must receive an Important Message from Medicare (IM) upon admission and again before planned discharge. The IM informs the beneficiary of the right to request a KEPRO discharge appeal. If the beneficiary requests the appeal promptly after receiving the second IM, the hospital cannot bill the beneficiary for continued stay while KEPRO reviews. KEPRO conducts a same-day or next-day medical review and issues a written decision. If KEPRO finds the discharge premature, the hospital must continue care without billing the beneficiary; if KEPRO finds the discharge appropriate, the beneficiary becomes financially responsible for further stay.

SNF, HHA, and hospice discharge appeals parallel the hospital discharge process. When a skilled nursing facility, home health agency, or hospice terminates services, the provider must issue a Notice of Medicare Non-Coverage (NOMNC) before termination. The beneficiary can request KEPRO review promptly after receiving the NOMNC. KEPRO conducts a same-day or next-day review.

Immediate Advocacy is KEPRO's informal complaint-resolution service. When a beneficiary calls KEPRO with a quality of care concern that does not rise to the level of a formal physician review, or when the beneficiary prefers a faster informal resolution, KEPRO staff can contact the provider, the plan, or other relevant parties on the beneficiary's behalf and attempt to resolve the issue without a formal review. Immediate Advocacy resolves many situations within hours or a few days.

KEPRO findings carry weight. KEPRO is an independent federal contractor, and KEPRO findings of substandard care can lead to provider corrective action, CMS enforcement, and in some cases Medicare provider termination. KEPRO does not order monetary remedies, but its findings often support subsequent malpractice or licensing actions. For Georgia beneficiaries, KEPRO is a parallel and complementary tool alongside the plan grievance process.

Parallel Agency Complaint Pathways for Georgia Beneficiaries

Beyond the plan-level grievance and the KEPRO process, Georgia Medicare beneficiaries can file complaints with several federal and state agencies. Each agency has distinct jurisdiction and distinct remedies.

CMS through 1-800-MEDICARE. Calling 1-800-MEDICARE (1-800-633-4227) connects the beneficiary to a CMS contractor that logs the complaint and routes it to the appropriate CMS Regional Office for the plan. The CMS complaint becomes part of the plan's record and contributes to CMS oversight and Star Ratings complaint measures. CMS does not adjudicate individual cases the way KEPRO or the appeals process does, but CMS Regional Offices can require plans to take corrective action and can refer plans for enforcement, including civil money penalties, intermediate sanctions such as enrollment suspension, and ultimately contract termination.

Georgia Department of Insurance. The Georgia Department of Insurance, reachable at 1-800-656-2298, regulates insurance agents and brokers operating in Georgia and has oversight authority over plan marketing conduct. Marketing complaints, agent misconduct complaints, and certain operational complaints fall within the Department's jurisdiction. The Department can investigate, impose penalties, suspend agent licenses, and refer matters for criminal prosecution. The Department's authority is concurrent with CMS marketing oversight. Beneficiaries should file marketing complaints with both the plan and the Department.

HHS Office of Civil Rights. The HHS Office of Civil Rights (OCR), reachable at 1-800-368-1019, enforces Section 1557 of the Affordable Care Act and other federal civil rights laws applicable to health programs receiving federal funds. Discrimination complaints based on race, color, national origin, sex, age, or disability should be filed with OCR. OCR investigates, can require corrective action, and in significant cases can refer matters for federal litigation by the Department of Justice.

HHS Office of Inspector General. The HHS Office of Inspector General (OIG), reachable at 1-800-447-8477 (1-800-HHS-TIPS), investigates Medicare fraud. Beneficiaries who believe a plan or provider has committed fraud (billing for services not provided, upcoding, kickbacks, false claims) should call OIG. The OIG hotline accepts anonymous tips. Substantiated fraud leads to civil money penalties, exclusion from Medicare participation, and in serious cases criminal prosecution.

Georgia Medicaid Fraud Control Unit. For Georgia beneficiaries who are dual-eligible (enrolled in both Medicare and Medicaid), the Georgia Medicaid Fraud Control Unit at 1-866-435-7644 investigates fraud involving Medicaid services. Many dual-eligible billing problems involve coordination failures between Medicare and Medicaid, and the Fraud Control Unit can address Medicaid-specific issues. The Unit operates within the Georgia Office of the Attorney General.

GeorgiaCares State Health Insurance Assistance Program. GeorgiaCares, reachable at 1-866-552-4464, is Georgia's federally funded State Health Insurance Assistance Program (SHIP). GeorgiaCares counselors provide free counseling on Medicare benefits, plan comparisons, and complaint navigation. GeorgiaCares counselors can help beneficiaries identify which complaint pathway is appropriate, draft grievances, and serve as authorized representatives.

Medicare Rights Center and Center for Medicare Advocacy. These two national nonprofit organizations provide free Medicare counseling and legal assistance. The Medicare Rights Center hotline is 1-800-333-4114; the Center for Medicare Advocacy is reachable at 1-860-456-7790. Both organizations have particular expertise in complex Medicare cases, denials, and grievance escalation.

Justice in Aging. Justice in Aging, reachable at 202-289-6976, is a national legal nonprofit focused on the rights of low-income older adults. Justice in Aging provides technical assistance to legal aid attorneys and beneficiary advocates and conducts policy advocacy on Medicare and Medicaid issues affecting older adults.

Atlanta Legal Aid Senior Citizens Law Project and Georgia Legal Services Program. For Georgia residents who qualify financially, Atlanta Legal Aid Senior Citizens Law Project at 404-377-0701 and Georgia Legal Services Program at 1-800-498-9469 provide free legal representation on Medicare issues including complex grievance and appeal matters. Georgia Legal Services serves Georgia residents outside the Atlanta metro area; Atlanta Legal Aid covers the five-county Atlanta region.

How Grievances Affect Star Ratings and Plan Accountability

Section 1853(o) of the Social Security Act authorizes the CMS Star Ratings program for Medicare Advantage plans. The implementing regulations at 42 CFR 422.160 through 422.166 establish the measure set and methodology. Within the Star Ratings framework, beneficiary complaints are tracked as discrete measures.

The complaint-related measures include Complaints about the Health Plan (Part C measure), Complaints about the Drug Plan (Part D measure), Members Choosing to Leave the Plan (Part C and Part D, which captures voluntary disenrollment that often correlates with dissatisfaction), and Plan Makes Timely Decisions about Appeals (Part C and Part D timeliness measures). The complaint measures carry heavy weighting under the CMS measure weighting framework. This weighting reflects CMS's policy judgment that beneficiary experience and service quality are the most consequential indicators of plan performance.

The numerical impact is significant. A plan with high complaint rates relative to peer plans loses Star Ratings points on the heavily-weighted complaint measures. The Star Rating directly determines Quality Bonus Payments (QBP). Plans rated 4 stars or higher qualify for Quality Bonus Payments that can translate to significant additional revenue depending on county benchmarks. A plan that slips from 4 stars to 3.5 stars loses these bonus payments, often resulting in tens of millions of dollars of lost revenue annually for a large plan.

A plan that consistently rates below 3 stars for multiple consecutive years can be terminated by CMS. When this occurs, every enrolled beneficiary receives a Special Enrollment Period to choose a new plan. The complaint measure category contributes to the overall rating that triggers termination eligibility.

Filing a grievance therefore has both individual and systemic effects. The individual beneficiary receives a written response within 30 days and may receive a corrective action specific to their situation. Aggregated grievance data shapes Star Ratings, affects Quality Bonus Payments, can trigger CMS enforcement actions, and in extreme cases drives plans out of the program. Beneficiaries who file grievances are not just seeking individual remedies. They are contributing to a federal accountability system designed to maintain quality standards across the Medicare Advantage program.

Worked Examples: Six Georgia Medicare Grievance Scenarios

Example 1: Margaret, Age 67, Atlanta, Customer Service Grievance for Phone Hold Times and Rude Representatives

Margaret enrolled in Humana Honor Medicare Advantage during the 2026 Annual Election Period and called the plan member services line in February 2026 to request a Summary of Benefits. She was placed on hold for forty-seven minutes before reaching a representative. When she finally connected, the representative was dismissive, refused to mail a paper Summary of Benefits, and told Margaret to download the document from the plan website. Margaret does not own a computer. The representative ended the call without providing a clear path to receive the document.

Margaret called back two days later and experienced a thirty-eight-minute hold. The second representative was helpful and promised to mail the Summary of Benefits, but Margaret was now frustrated about the recurring service failure. She decided to file a grievance.

This is a customer service grievance under 42 CFR 422.564. Margaret has two filing pathways and uses both. First, she calls the Humana grievance line (printed on the back of her member ID card) and describes both call experiences. She requests a written response. The Humana representative documents the grievance, provides a reference number, and confirms a 30-day response timeline. Margaret simultaneously calls 1-800-MEDICARE and logs a parallel complaint with CMS. The 1-800-MEDICARE complaint feeds into Humana's CMS complaint record.

Twenty-two days later, Humana sends Margaret a written response acknowledging the long hold times and the unhelpful representative interaction. Humana confirms that the first representative has been counseled and that Humana has implemented new staffing during peak periods. Margaret has received an individual response and a corrective action. Her grievance also contributes to Humana's CMS complaint rate, which feeds the Star Ratings measure for Complaints about the Health Plan. Margaret's individual complaint is one data point. Aggregated with similar complaints, it can affect Humana's Star Rating.

If Margaret needed additional help, she could contact GeorgiaCares for free SHIP counseling on the response and on whether to escalate further.

Example 2: Robert, Age 70, Savannah, Hospital Discharge KEPRO Appeal and Quality of Care Grievance

Robert is enrolled in Aetna Medicare Advantage PPO and was admitted to a Savannah hospital with congestive heart failure exacerbation in March 2026. On hospital day five, Robert received the second Important Message from Medicare informing him the hospital intended to discharge him the next morning. Robert still felt short of breath, was not yet ambulating without assistance, and believed the discharge was premature.

Robert has the right to a KEPRO hospital discharge appeal under federal regulations. He contacted KEPRO promptly after receiving the second Important Message. The hospital could not bill Robert for the additional stay while KEPRO conducted the review. KEPRO physicians reviewed Robert's medical record and determined that the planned discharge was premature based on Robert's continued shortness of breath, unstable diuretic requirements, and lack of ambulation. KEPRO ordered the hospital to provide an additional 48 hours of inpatient care without billing Robert.

Robert then filed a parallel quality of care grievance with Aetna, his Medicare Advantage plan, asking the plan to review whether the hospital's discharge planning had been adequate and whether the plan's case management had appropriately overseen the inpatient stay. Aetna documented the grievance and responded within 30 days, confirming that Aetna had spoken with the hospital case management department, that the hospital had agreed to revise its CHF discharge protocols to incorporate stricter functional status criteria, and that Aetna would monitor the hospital's future CHF discharges. Robert also called 1-800-MEDICARE to log a complaint with CMS, ensuring that the discharge concern entered the CMS record.

Robert used three parallel pathways: KEPRO (independent medical review under Section 1154 of the Social Security Act), the plan grievance (under Section 1852(f) and 42 CFR 422.564), and the CMS complaint hotline. Each pathway has a different remedy and a different oversight effect. Together they produced both an immediate clinical benefit (the 48-hour extension) and a systemic improvement (revised hospital protocols).

Example 3: Linda, Age 68, Macon, Prior Authorization Timeliness Grievance

Linda is enrolled in Wellcare Medicare Advantage HMO. In April 2026, her orthopedic surgeon requested prior authorization for a total knee replacement scheduled for May 2026. Medicare Advantage plans have regulatory timeliness standards for processing prior authorization requests. Linda's surgeon submitted the request on April 5. By April 19, Wellcare had not responded. The surgeon's office called Wellcare on April 19 and was told the case was still under review. On April 23, eighteen days after submission, Wellcare approved the prior authorization. Linda's surgery proceeded as scheduled.

Although Linda ultimately received the authorization, Wellcare had missed the regulatory processing deadline. This is a grievance, not an appeal, because the request was approved. The grievance addresses the operational failure of the plan in missing the regulatory deadline. Linda's surgeon's office filed a grievance with Wellcare on Linda's behalf (as an authorized representative under 42 CFR 422.561). The grievance described the timeline, identified the regulatory deadline missed, and requested a written response.

Wellcare responded within 25 days, acknowledging the timeliness failure, citing internal staffing issues, and describing corrective action: increased prior authorization staffing and a new internal monitoring report tracking processing times. Linda's surgeon's office logged the grievance reference number for use in future cases involving the same plan.

The Wellcare CMS Star Ratings include the Plan Makes Timely Decisions about Appeals measure and related operational measures. Linda's grievance contributes to those measures. Beyond Star Ratings effects, a recent CMS rulemaking, effective plan year 2026, strengthened prior authorization timeliness requirements and gave CMS additional enforcement authority. Plans that repeatedly miss timeliness standards face increased oversight.

Example 4: Charles, Age 72, Augusta, Marketing Complaint to the Plan and Georgia Department of Insurance

Charles attended a Medicare educational seminar in Augusta during the 2025 Annual Election Period (October-December 2025). The agent presenting at the seminar represented Anthem Blue Cross Blue Shield Medicare Advantage. The agent stated that the plan included comprehensive dental coverage with "no limits on major services" including implants. Based on this representation, Charles enrolled in the plan effective January 1, 2026.

In February 2026, Charles consulted a dentist who recommended a dental implant. Charles called Anthem to verify coverage and learned that the plan covered comprehensive dental services up to a $2,000 annual maximum and excluded implants entirely. The agent's representation had been false. Charles had relied on the misrepresentation in enrolling.

Charles filed a grievance with Anthem describing the agent's misrepresentation, the date and location of the seminar, the agent's name, and the financial consequence (he was now in a plan that did not match his needs). Anthem documented the grievance and investigated the agent. Anthem responded within 28 days, confirming that the agent had been counseled, that the agent's marketing materials had been reviewed, and that Anthem had reported the incident through its compliance program.

Charles also filed a parallel complaint with the Georgia Department of Insurance at 1-800-656-2298. The Department investigates insurance agent and broker conduct in Georgia. The Department's investigation can result in agent license suspension, civil penalties under Georgia insurance law, and referral for criminal prosecution if the misrepresentation rose to the level of insurance fraud.

Charles also exercised his Medicare Advantage Open Enrollment Period right under 42 CFR 422.62(a)(3) to disenroll from Anthem and enroll in a different plan effective March 1, 2026. The MA OEP runs January 1 through March 31 and allowed Charles to leave the plan based on the marketing failure (see Brevy's separate guide at /medicaid/georgia/medicare-disenrollment-and-trial-rights for the full framework).

The marketing complaint pathway operates at three levels: the plan grievance produces a corrective action; the Georgia DOI complaint produces a regulatory investigation; the CMS complaint (logged via 1-800-MEDICARE) feeds the CMS oversight system and Star Ratings.

Example 5: Patricia, Age 65, Columbus, Pharmacy Network Adequacy Grievance

Patricia enrolled in a Cigna Medicare Advantage HMO with prescription drug coverage effective January 1, 2026. The plan's published pharmacy network listed three in-network pharmacies within ten miles of her home. When Patricia attempted to fill her first prescription at the closest pharmacy, she learned that the pharmacy had terminated its Cigna contract effective December 31, 2025. The next-closest in-network pharmacy was 28 miles from her home. The next after that was 35 miles.

Patricia does not drive long distances comfortably. The 28-mile pharmacy required a one-hour round-trip drive each month for her chronic medications. Patricia called Cigna to complain. The Cigna representative confirmed the network adequacy gap, suggested mail-order pharmacy as an alternative, and acknowledged the inconvenience. Mail order was not a workable solution for Patricia because she frequently needed to consult the pharmacist about her medications and preferred face-to-face interaction.

Patricia filed a pharmacy network adequacy grievance with Cigna. The grievance described the network gap and the impact on her access to medication. Under 42 CFR 423.120, Part D plans must maintain pharmacy networks that meet CMS network adequacy standards, which require convenient access including pharmacies within specified distances of enrollees. Cigna responded within 30 days, acknowledging the network gap, confirming that Cigna was in active contract negotiations with two additional Columbus-area pharmacies, and offering Patricia a courtesy mail-order solution with overnight delivery and access to a pharmacist consultation line.

Patricia also called 1-800-MEDICARE to log a complaint with CMS. CMS evaluates Part D pharmacy network adequacy at the contract level, and complaint patterns can trigger CMS reviews of plan network maintenance. The complaint also contributes to the Complaints about the Drug Plan Star Ratings measure.

Example 6: Henry, Age 73, Athens, Provider Conduct Grievance

Henry is enrolled in Kaiser Permanente Medicare Advantage HMO. He selected a primary care physician (PCP) in Athens. Over the course of three visits in early 2026, Henry experienced a pattern of problems with the PCP's office: the receptionist was consistently rude, the medical assistant rushed his vitals and ignored his questions, the office was visibly dirty (sticky floors, unsanitary patient bathrooms, dust on equipment), and the PCP herself dismissed Henry's concerns about a persistent cough as "old age" without ordering any diagnostic workup.

Henry switched to a different PCP within the Kaiser network for his April 2026 appointment. The new PCP took Henry's cough seriously, ordered a chest x-ray, and identified an early-stage pneumonia that the previous PCP had missed.

Henry filed a provider conduct grievance with Kaiser, describing the receptionist behavior, the medical assistant rushing, the office conditions, and the PCP's dismissive clinical approach. Henry also asked Kaiser to evaluate whether the missed pneumonia represented a quality of care concern. Kaiser documented the grievance and responded within 30 days. Kaiser confirmed that the office had been inspected, that the office had received a written corrective action notice, that the office staff had received training on patient interaction, and that Kaiser's medical director was reviewing the clinical care.

Henry also filed a parallel quality of care complaint with KEPRO. KEPRO physicians conducted an independent medical review of the cough evaluation and determined that the failure to order any diagnostic workup on a persistent cough in a 73-year-old patient did not meet generally accepted standards of care. KEPRO documented the finding, reported it to the provider, and notified Henry. The KEPRO finding can support subsequent action against the PCP through the Georgia Composite Medical Board if Henry chooses to file a separate licensing complaint.

Henry used three pathways: the plan grievance (Kaiser corrective action), the KEPRO quality of care review (independent medical finding), and the potential Medical Board pathway (provider licensing). Each addresses a different aspect of the failure and provides a different remedy.

Thirteen Common Grievance Mistakes Georgia Beneficiaries Should Avoid

Filing a grievance when you should file an appeal. If the plan denied a service or payment, you need an appeal, not a grievance. Filing a grievance against the denial wastes 30 days and does not produce reversal of the denial. Always identify whether the underlying issue is an Adverse Benefit Determination (appeal) or an operational concern (grievance).

Filing an appeal when you should file a grievance. Conversely, if the plan operated incorrectly but did not deny a service, filing an appeal is the wrong tool. An appeal can only review an Adverse Benefit Determination. Operational complaints belong in the grievance channel.

Filing only one when both apply. Many situations require both a grievance and an appeal. A denial after an eleven-day prior authorization delay requires an appeal (against the denial) and a grievance (against the delay). Filing only one leaves part of the problem unaddressed.

Not using KEPRO for quality of care issues. Quality of care concerns warrant parallel filings with KEPRO. The plan grievance produces a plan-level response, but KEPRO conducts independent physician-level medical review. Skipping KEPRO loses the most powerful quality of care remedy available.

Not documenting the timeline. Every grievance benefits from a written timeline with dates, names, phone numbers, and quotes. When the plan responds, the response is evaluated against your documented timeline. Vague timeline descriptions weaken the grievance.

Not requesting a written response. Even when filing orally, you should request a written response. Written responses create a permanent record, are auditable by CMS, and provide leverage for any subsequent escalation.

Missing the 30-day plan response deadline without follow-up. If the plan exceeds 30 days and has not invoked the 14-day extension in writing, the plan has missed its regulatory deadline. Document the missed deadline and consider parallel filing with CMS through 1-800-MEDICARE.

Filing only with the plan and not with parallel agencies. The plan grievance is one tool. CMS, KEPRO, the Georgia Department of Insurance, HHS OCR, HHS OIG, and the Georgia Medicaid Fraud Control Unit all have distinct jurisdictions. Marketing complaints in particular should go to both the plan and the Georgia DOI. Discrimination complaints should go to both the plan and HHS OCR.

Not designating an authorized representative. Under 42 CFR 422.561, an authorized representative can file and pursue a grievance on the beneficiary's behalf. Family members, SHIP counselors, and attorneys can serve as representatives. Designating a representative is especially valuable for beneficiaries with cognitive or communication impairments.

Allowing the plan to dissuade filing. Some plan representatives may discourage grievance filings or attempt to handle the complaint informally without documenting it as a grievance. The beneficiary has a federal right to a documented grievance with a 30-day written response. Insist on the formal grievance process.

Not following up with the plan after the response. A plan response that promises corrective action but does not actually implement the action is itself a grievable failure. Follow up to verify that the corrective action occurred.

Forgetting that grievances feed Star Ratings. Individual grievances aggregate into CMS Star Ratings complaint measures. The heavy weighting on complaint measures means complaints have outsized impact on plan ratings. Filing is not just an individual remedy; it is also a contribution to plan accountability.

Confusing the expedited 24-hour grievance with general grievances. The expedited grievance under 42 CFR 422.564 applies only to refusals to expedite an organization determination or appeal. It does not apply to general operational or quality of care complaints. Misclassifying a complaint as expedited will not change the response timeline for non-qualifying situations.

Frequently Asked Questions

What is the difference between a grievance and an appeal?

An appeal challenges an Adverse Benefit Determination, meaning a denial of coverage or payment for a service or drug. Appeals move through a five-level federal process. A grievance addresses anything that is not a coverage or payment denial: customer service, marketing, provider conduct, quality of care, prior authorization timeliness, plan operations, pharmacy operations, and discrimination. Grievances are resolved at the plan level with a 30-day response standard.

How long does the plan have to respond to a grievance?

Under 42 CFR 422.564 for Medicare Advantage and 42 CFR 423.564 for Part D, the plan must respond within 30 days of receipt. The plan may extend the period by up to 14 days if the extension is in the best interest of the enrollee, and the plan must notify the enrollee in writing of any extension. For expedited grievances, the plan must respond within 24 hours.

What is KEPRO and when do I call them?

KEPRO is the federally contracted Quality Improvement Organization (QIO) for Georgia under Section 1154 of the Social Security Act. Contact KEPRO (see the resource list below) for quality of care complaints about any Medicare-participating provider, hospital discharge appeals when you receive an Important Message from Medicare and believe the discharge is premature, skilled nursing facility, home health agency, and hospice discharge appeals, and Immediate Advocacy for informal complaint resolution.

How do I file a hospital discharge appeal?

When you are admitted to the hospital, you receive an Important Message from Medicare. You receive a second Important Message before planned discharge. If you believe the discharge is premature, contact KEPRO promptly after receiving the second Important Message and request the appeal. KEPRO conducts a same-day or next-day review. While KEPRO reviews, the hospital cannot bill you for continued stay.

Is there a free counselor who can help me with a grievance?

Yes. GeorgiaCares, Georgia's State Health Insurance Assistance Program (SHIP), provides free counseling. GeorgiaCares counselors can help identify the right complaint pathway, draft grievances, and serve as authorized representatives. Contact information is in the resource list below. :::
