Georgia Medicaid Prior Authorization (2026): FFS, CMO, Appeals

The Georgia Medicaid prior authorization process is the utilization-management gate that decides whether a requested service is medically necessary and covered before it is provided. Prior authorization (PA) runs through two pathways depending on whether the member is in fee-for-service or one of the three Georgia Families Care Management Organizations (CMOs). For rating periods that start on or after January 1, 2026, the deciding plan must answer a standard PA request within 7 calendar days and an urgent (expedited) request within 72 hours, under 42 CFR 438.210 and the Centers for Medicare and Medicaid Services (CMS) Interoperability and Prior Authorization Final Rule (CMS-0057-F).1,2 This guide walks through the federal framework, the fee-for-service and CMO pathways, what requires PA, standard and expedited timelines, peer-to-peer reviews, the most common denial reasons, and how to navigate the internal appeal and State Fair Hearing process.

The federal framework for the Georgia Medicaid prior authorization process

Prior authorization rests on two federal regulatory anchors. 42 CFR 440.230(d) authorizes states to place appropriate limits on Medicaid services based on medical necessity or utilization-control procedures, the foundation of all Medicaid PA. 42 CFR 438.210 governs PA in Medicaid managed care, including the decision timelines and the role of clinical expertise in PA decisions.

Under 42 CFR 438.210(d), for rating periods that start on or after January 1, 2026, a managed care plan must make a standard service-authorization decision within 7 calendar days of receiving the request, and an expedited decision within 72 hours when the standard timeframe could seriously jeopardize the enrollee's life, health, or ability to attain, maintain, or regain maximum function. (For rating periods that started before January 1, 2026, the prior 14-calendar-day standard cap still applied.) A plan may extend either timeframe by up to 14 additional calendar days if the enrollee or provider requests it, or if the plan justifies a need for more information that is in the enrollee's interest.1

The most consequential federal change for the prior authorization process is the CMS Interoperability and Prior Authorization Final Rule (CMS-0057-F, finalized 2024), which sets the same operational standards across impacted payers, including Medicare Advantage, Medicaid and CHIP fee-for-service, Medicaid and CHIP managed care, and qualified health plan issuers on the federally facilitated exchanges. Its operational provisions generally begin January 1, 2026:2

• Standard PA decisions within 7 calendar days and expedited (urgent) decisions within 72 hours
• A specific reason stated for each denial
• Public reporting of prior-authorization metrics, with the first CY2025 metrics posted by March 31, 2026
• The Patient Access, Provider Access, Payer-to-Payer, and Prior Authorization APIs (Fast Healthcare Interoperability Resources, or FHIR, based) for electronic submission and tracking, with a separate, later compliance date generally beginning January 1, 2027

Federal Medicaid pharmacy law requires prompt PA decisions on complete requests and an emergency-supply mechanism so a member can receive an immediate short supply while PA is pending; pull the current Georgia Department of Community Health (DCH) pharmacy PA page for the operative turnaround standard.

The two PA pathways: FFS and CMO

Georgia Medicaid splits prior authorization into two operational pathways based on whether the member is enrolled in fee-for-service (FFS) or in one of the three Georgia Families CMOs.

Fee-for-service pathway

A meaningful share of Georgia Medicaid beneficiaries remain in fee-for-service, including most long-term-care residents in nursing facilities, HCBS waiver participants (CCSP, SOURCE, ICWP, NOW, COMP, Independent Care Waiver Program), dual eligibles for Medicaid wrap-around services, and certain medically complex populations. Pull current FFS enrollment shares from DCH before relying on a specific percentage.

PA for these beneficiaries is processed by:

• Gainwell Technologies (Georgia Medicaid Fiscal Agent): handles PA for medical/surgical services, durable medical equipment, inpatient (in coordination with the QIO), outpatient, and most non-pharmacy FFS services through the Georgia Medicaid Management Information System (GAMMIS). Portal: gammis.com. Phone: 1-800-766-4456. Fax: 1-866-211-6916.
• OptumRx (FFS Pharmacy Benefits Manager): OptumRx is the PBM for the Georgia Medicaid fee-for-service outpatient pharmacy program and handles FFS pharmacy PA per DCH; pull the current OptumRx pharmacy PA contacts from the DCH pharmacy provider page.4
• Alliant Health Solutions: Quality Improvement Organization (QIO) for inpatient admission certification and concurrent review.

CMO pathway

The remaining beneficiaries are enrolled in one of the three CMOs, and PA is processed by the CMO's internal utilization-management department. Each CMO maintains its own PA forms, clinical criteria (typically based on InterQual or MCG, customized to Georgia Medicaid requirements), and provider portal for electronic submission. Pharmacy PA for CMO members runs through the member's own CMO and its PBM, not through the FFS PBM. As of 2026 the Georgia Families roster is three CMOs (Amerigroup Community Care, CareSource, and Peach State Health Plan); WellCare is no longer a separate Georgia Families Medicaid CMO. A 2024 reprocurement remains in the bid-protest phase as of 2026, so verify the current roster with DCH before relying on it.3

Standard and expedited timelines under the Georgia Medicaid prior authorization process

The CMS-0057-F final rule and the longstanding 42 CFR Part 438 appeal timeframes together set the operative PA clock. The figures below apply to rating periods that start on or after January 1, 2026.1,5,6,7

Critical practice point: requesting continuation of benefits is the most frequently missed step in Medicaid appeals. Federal rules at 42 CFR 431.230 continue services during the appeal when the member requests a hearing before the action takes effect; in Georgia, DCH operationalizes this as a request made within 10 calendar days of the notice. Without continuation of benefits, the member loses access to the service during the appeal even if they ultimately prevail.

What requires PA in the Georgia Medicaid prior authorization process

States may place medical-necessity and utilization-control limits on covered services under 42 CFR 440.230(d), and managed care plans authorize services under 42 CFR 438.210; the exact list of services requiring PA updates periodically. Verify current requirements at gammis.com (FFS) or in the relevant CMO provider manual. Operational PA categories include:1

Pharmacy

• All non-preferred drugs on the Georgia Medicaid Preferred Drug List
• Brand-name drugs when a generic exists
• Specialty pharmacy products (hepatitis C antivirals, oncology, biologics, immunomodulators)
• Opioids beyond initial acute-supply windows
• Buprenorphine for opioid use disorder beyond an initial grace period
• Long-acting injectable antipsychotics, growth hormone, ESAs, and other biologics
• Compounded medications above threshold dollar amounts

Durable medical equipment

Georgia Medicaid DME is administered as a tiered framework. Lower-cost basic items (basic walkers, manual wheelchairs, glucometers, CPAP supplies) do not require PA; mid-tier items (standard hospital beds, mobility scooters, oxygen concentrators) move through streamlined PA; complex items (power wheelchairs Group 2 and above, continuous glucose monitors, bariatric equipment, BiPAP, ventilators, wound-VAC, complex pediatric DME) require full PA. Capital purchases above the DME policy threshold and rentals beyond an initial period also require PA; pull the current DME policy for specific dollar thresholds.

Inpatient and acute care

All scheduled or elective inpatient admissions, length-of-stay extensions beyond initial certification, acute inpatient psychiatric care (with concurrent review at defined intervals), inpatient rehabilitation, long-term acute care hospitals, and skilled nursing facility admissions for Medicare-Medicaid duals require PA.

Outpatient procedures

Outpatient surgery above policy dollar thresholds, advanced imaging (MRI, CT, PET) beyond defined frequency, cardiac catheterization, bariatric surgery, spinal surgery, joint replacement, genetic testing, sleep studies, and hyperbaric oxygen.

Behavioral health

Inpatient psychiatric admission, Psychiatric Residential Treatment Facility (PRTF) for under-21, partial hospitalization, intensive outpatient programs beyond initial authorization, Applied Behavior Analysis for autism, therapy sessions beyond standard initial allotments, ECT, and TMS.

Home health and personal care

Home health services beyond an initial episode, private-duty nursing (all hours), personal care services (authorized through the member's care coordinator), and HCBS waiver services (continuous care plan PA through the service coordinator).

Therapy services

Physical, occupational, and speech therapy beyond an initial visit allotment for adults; ABA for autism; cognitive rehabilitation.

Transportation, vision, hearing, dental

Non-emergency medical transportation (NEMT) exceptions for out-of-area or specialty needs; air ambulance (always PA except true emergency); inter-facility transport. Eyeglasses beyond a standard frame allowance; specialty eyewear; hearing aids; cochlear implants. Adult dental is emergency-only over age 21; pediatric orthodontia is EPSDT-funded only if medically necessary.

How to submit a PA request

Peer-to-peer reviews

A peer-to-peer (P2P) review is a clinical discussion between the requesting provider and the CMO's medical reviewer (typically a physician) before a final denial. P2P is the single most effective tool for reversing initial denials before formal appeal.

All three Georgia CMOs offer P2P review. Providers must typically request P2P within a short window after the initial denial (varies by CMO; pull the current Provider Manual). The CMO's UM department schedules the discussion, typically 15-30 minutes, focused on clinical rationale.

P2P outcomes include approval (original denial reversed, service approved); modification (alternative service approved, such as less-expensive DME or alternative therapy course); and denial upheld (member can proceed to internal appeal). P2P is not an appeal: it is a pre-appeal clinical conversation. Filing an internal appeal is a separate, formal process with its own 60-day filing window.

The appeal process under the Georgia Medicaid prior authorization process

Step 1: CMO internal appeal (mandatory for managed care)

Under 42 CFR 438.402, a managed care plan may have only one level of appeal for enrollees, and the member or authorized representative must exhaust that internal appeal before requesting a State Fair Hearing. An appeal may be requested orally or in writing: by phone (an oral appeal must be followed by a written, signed appeal), by mail to the CMO appeals address (in the denial notice), by fax to the CMO appeals fax (in the denial notice), or online through the CMO member portal.6

Key parameters:5

• Filing window: 60 calendar days from the date on the adverse benefit determination notice (42 CFR 438.402(c)(2)(ii))
• Resolution: 30 calendar days for a standard appeal and 72 hours for an expedited appeal, each extendable by up to 14 calendar days (42 CFR 438.408(b))
• Continuation of benefits: available if requested within 10 calendar days of the notice
• Right to review the file: the member can request and receive, free of charge, the case file and the medical-necessity criteria used to make the determination
• Right to submit additional information: written documents, witness statements, and additional medical records

Step 2: State Fair Hearing

After exhausting the internal appeal, the member must be given no less than 90 and no more than 120 calendar days from the date of the CMO's resolution notice to request a State Fair Hearing under 42 CFR 438.408(f); the exact deadline within that band is set by each state, so confirm Georgia's current window with DCH or OSAH before relying on it. In Georgia, hearings are conducted by the Office of State Administrative Hearings (OSAH).7

• Filing: submit to DCH Member Services (1-866-211-0950) or to OSAH directly (1-404-657-3300)
• Hearing scheduled and decision rendered: OSAH publishes its standard timelines; pull the current OSAH procedural rules
• Representation: member may be represented by an attorney, advocate, family member, or other person. Atlanta Legal Aid Society and Georgia Legal Services Program provide free representation for income-eligible beneficiaries.
• Continuation of benefits: available if requested within 10 days

Step 3: Judicial review

Final OSAH decisions may be appealed to Georgia Superior Court under the Georgia Administrative Procedure Act. Pull the current Georgia APA judicial-review window from counsel before filing. The standard of review is substantial evidence, with deference to the agency on matters within its expertise.

Adverse benefit determination notices

Under 42 CFR 438.404, the denial notice must include the adverse benefit determination; the reasons for the decision (specific to the case, not generic), including the right to free copies of the documents and the medical-necessity criteria used; the right to file an appeal and the procedures for doing so; the right to request a State Fair Hearing after the internal appeal; the circumstances under which an appeal can be expedited and how to request it; the right to have benefits continue pending the appeal and how to request continuation; and the member's potential liability if benefits are continued and the determination is upheld. When a plan fails to meet these notice and timing requirements, the enrollee is deemed to have exhausted the internal appeal and may go straight to a State Fair Hearing.8

Common denial reasons and how to respond

1. Lack of medical necessity documentation. The leading cause of initial denial. UM reviewers look at clinical notes, not PA form check-boxes. Provide complete progress notes, imaging reports, lab results, and a detailed clinical narrative tying the diagnosis to the requested service. For DME, include the face-to-face encounter note. For pharmacy, include trial-and-failure documentation for PDL alternatives.
2. Failure to trial preferred alternatives. Pharmacy PA requires documented trial of PDL preferred drugs first. DME PA requires documentation of less-expensive alternatives. Therapy PA may require documentation of less-intensive services. Submit a trial log with dates, dosages or treatment intensity, response, and reason for discontinuation.
3. Service exceeds policy limits. Therapy visits over annual cap, imaging over allowed frequency, opioid days supply over acute limit. Document medical necessity for additional units. Cite EPSDT for under-21 to bypass standard adult caps.
4. Out-of-network provider. If the requested provider is out of the CMO network, request a single-case agreement; demonstrate unique expertise unavailable in-network; document attempts to secure in-network care that failed.
5. Member not eligible at date of service. Verify eligibility through Gateway; if member should have been eligible (procedural termination within reconsideration window), pursue retroactive reinstatement; submit retroactive PA after eligibility restored.
6. Service not covered for adult population. Adult dental, limited adult vision, hearing aids. For members under 21, cite Early and Periodic Screening, Diagnostic, and Treatment (EPSDT): under Social Security Act Section 1905(r) (42 U.S.C. 1396d(r)), Medicaid must cover any medically necessary service that corrects or ameliorates a condition found through screening, whether or not that service is otherwise covered for adults under the state plan.9
7. Documentation incomplete. Missing face-to-face encounter note for DME, missing PA form fields, missing diagnosis codes. Resubmit with complete documentation; typically the fastest path to approval.
8. Service requires step therapy. Submit step-therapy documentation; if patient has contraindication to preferred alternative, document clinical reason; if patient was previously stable on the requested drug, request stabilization exception.

Worked examples of the Georgia Medicaid prior authorization process

Standard PA: Marcus (49), CareSource, scheduled knee MRI

Marcus's PCP orders an MRI for suspected meniscal tear with mechanical symptoms and failed conservative treatment (physical therapy for several weeks, NSAIDs, knee brace). The PCP submits PA via the CareSource provider portal with imaging history and clinical notes. The CareSource UM nurse reviews the next day. Documentation supports medical necessity. PA approved within the standard window. MRI scheduled the following week.

Expedited PA: Aisha (4), Peach State, home IV antibiotic

Aisha has a cystic fibrosis exacerbation hospitalized on a Friday. The discharge plan is a 14-day IV antibiotic course via home infusion. The hospital case manager submits an expedited PA with clinical jeopardy attestation (early discharge dependent on PA approval). The Peach State UM nurse reviews the next morning. PA approved within the expedited window. Home infusion company delivers equipment; Aisha discharged Monday afternoon.

Emergency pharmacy supply: Robert (62), FFS, hepatitis C treatment

Robert is diagnosed Hep C and prescribed Mavyret. As an FFS member, his pharmacy submits to OptumRx, the FFS pharmacy benefits manager; the specialty antiviral requires PA. The pharmacy dispenses an emergency short supply immediately under federal Medicaid pharmacy law. The specialist submits PA documentation the next day with viral load, genotype, treatment-naive status, and fibrosis score. PA approved promptly on a complete request. The full course is dispensed without interruption.4

Denial reversed at peer-to-peer: Sarah (9), Amerigroup, Group 3 power wheelchair

Sarah has spastic quadriplegic cerebral palsy. Her assistive technology professional evaluation is completed; a Group 3 power wheelchair is requested with tilt-in-space, custom seating for scoliosis management, and head array. Amerigroup's initial PA review denies citing "Group 2 may meet needs." Sarah's PT requests a peer-to-peer review within the CMO's required window. During the discussion, the PT documents tilt-in-space requirement for pressure relief, custom seating for spinal alignment, and head array for severe upper-extremity involvement. The medical director agrees Group 3 is medically necessary. PA approved; equipment ordered.

Internal appeal: David (54), CareSource, denied bariatric surgery

David has BMI in the bariatric-surgery range plus T2DM, hypertension, and sleep apnea. The bariatric surgeon submits PA. CareSource denies citing "medically supervised weight-loss program documentation insufficient." David's surgeon files an MCO internal appeal with additional documentation: dietitian records, exercise log, weight-loss attempts, comorbidity progression. CareSource resolves the appeal within the standard 30-day window and approves the laparoscopic gastric sleeve.

State Fair Hearing: Eleanor (78), Amerigroup, denied SNF transfer

Eleanor is hospitalized after a stroke. Discharge is planned to a skilled nursing facility for sub-acute rehab. Amerigroup denies the SNF transfer, citing "skilled rehab can be provided at home with home health agency services." The daughter files an MCO internal appeal; Amerigroup's expedited review upholds the denial. The daughter files a State Fair Hearing with OSAH and requests continuation of benefits within 10 days. At the OSAH hearing, PT, OT, and the discharge planner testify that Eleanor's mobility deficits and ADL impairment require 24/7 nursing oversight. The ALJ rules the SNF admission medically necessary; Amerigroup's decision is reversed; Eleanor is admitted to the SNF.

Things commonly missed in the Georgia Medicaid prior authorization process

1. Submitting PA without complete clinical documentation is the leading cause of initial denial; the PA form is the cover sheet, not the case.
2. Not knowing whether the member is fee-for-service or CMO sends the request to the wrong pathway and delays the decision.
3. Missing the peer-to-peer request window forfeits the single most effective pre-appeal reversal tool.
4. Filing the internal appeal late: the 60-calendar-day window from the notice is firm, and missing it forfeits appeal rights.
5. Not requesting continuation of benefits within 10 calendar days, which means the member loses service access during the appeal.
6. Confusing FFS pharmacy with CMO pharmacy: FFS pharmacy PA runs through OptumRx (the FFS PBM per DCH), while CMO members get pharmacy PA through their own CMO and its PBM.
7. Forgetting that EPSDT modifies PA criteria for members under 21: pediatric PA must apply the correct-or-ameliorate standard, not standard adult criteria.
8. Not preserving a documentation timeline: keep dated copies of all submissions, faxes, phone confirmations, and notices.

A few more common questions:

Can I keep getting the service while I appeal? Yes. Federal rules at 42 CFR 431.230 continue services during an appeal when the member requests the hearing before the action takes effect; in Georgia, DCH operationalizes this as filing your internal CMO appeal and requesting continuation of benefits within 10 calendar days of the denial notice. If you lose the appeal, you may be required to repay benefits received during continuation. The 10-day window is the most frequently missed deadline in Medicaid appeals; mark it carefully.10

Does my pharmacy need PA for my medication? Most medications on the Georgia Medicaid Preferred Drug List do not require PA. Non-preferred drugs, brand-name drugs when a generic exists, specialty pharmacy products (hepatitis C antivirals, oncology, biologics), opioids beyond initial acute-supply windows, and certain other categories require PA. If you are in fee-for-service, that PA goes through OptumRx, the FFS pharmacy benefits manager per DCH; if you are in a Georgia Families CMO, it goes through your CMO and its pharmacy benefit manager. For urgent need, the pharmacy can dispense an emergency short supply while PA is pending.4

My child needs a service the CMO says is not covered. Can EPSDT help? Yes. Under Early and Periodic Screening, Diagnostic, and Treatment (EPSDT), Medicaid is required to cover any medically necessary service for children under 21 that corrects or ameliorates a physical or mental condition, including services not generally covered for adults. PA criteria for children must apply this broader correct-or-ameliorate standard. If a CMO denies a service for your child citing standard adult criteria, request EPSDT review or file an appeal.9
