Georgia Medicare Advantage: Plan Types, Enrollment, and How to Choose

::: hero

By Brevy Care Team · Last verified May 13, 2026

Medicare Advantage, also called Medicare Part C, is now the dominant Medicare delivery model in Georgia. A majority of Georgia Medicare beneficiaries are enrolled in Medicare Advantage plans in 2026. This shift represents one of the most significant restructurings of senior health coverage in American history, driven by a combination of attractive plan benefits (often $0 premiums, integrated Part D coverage, dental and vision benefits, fitness programs), aggressive carrier marketing, and a policy environment that has consistently expanded MA payments and flexibility.

Federal Authority: Section 1851 of the Social Security Act (42 USC 1395w-21), Sections 1852-1857, and 1859 SSA, and 42 CFR Part 422

Plan Types: HMO, PPO, PFFS, MSA, SNPs (D-SNP, C-SNP, I-SNP, FIDE-SNP, HIDE-SNP)

Annual Election Period (AEP): October 15 through December 7. Coverage effective January 1.

MA Open Enrollment Period (MA-OEP): January 1 through March 31 for existing MA enrollees only.

2025 Part D OOP Cap: $2,000 annual maximum under IRA 2022 Section 11201 (applies to MA-PD plans)

::: callout Key Takeaways for Georgia Medicare Advantage

• Annual Election Period (AEP) runs October 15 through December 7; coverage effective January 1. This is the primary window to switch plans each year.
• The 2025 Part D $2,000 OOP cap under IRA 2022 Section 11201 dramatically reduces specialty drug costs for MA-PD enrollees.
• Prior authorization timelines: standard 7 calendar days, expedited 72 hours, under the 2024 CMS final rule.
• Five-level appeals process: plan reconsideration → IRE (Maximus) → ALJ → Medicare Appeals Council → federal court.
• D-SNPs provide integrated Medicare-Medicaid coverage for dual-eligible Georgians, typically with $0 premium and $0 cost-sharing. :::

The federal framework for Medicare Advantage rests on Section 1851 of the Social Security Act (42 USC 1395w-21) and surrounding provisions including Section 1852 (benefits), Section 1853 (payments and Star Ratings), Section 1854 (premiums), Section 1857 (CMS contracts with MA organizations), and Section 1859 (Special Needs Plans). The implementing regulations at 42 CFR Part 422 govern eligibility, enrollment, benefits, network adequacy, prior authorization, marketing, appeals, and grievances. Federal oversight has been strengthened over the years through MMA 2003 (which renamed Medicare+Choice to Medicare Advantage and added Part D integration), MIPPA 2008 (consumer protections), the Affordable Care Act 2010 (Star Ratings authority, payment reforms, MLR requirements), the Bipartisan Budget Act 2018 (Value-Based Insurance Design demonstrations, expanded supplemental benefits), and the Inflation Reduction Act 2022 (Part D out-of-pocket cap of $2,000 effective 2025, insulin $35 cap, vaccine cost-sharing elimination).

For Georgia families, the decision between Medicare Advantage and Original Medicare plus Medigap is one of the most consequential health coverage choices of retirement. The decision involves real tradeoffs: lower or $0 monthly premiums versus network restrictions, integrated supplemental benefits versus prior authorization requirements, predictable out-of-pocket maximums versus limited provider choice, simplified single-card coverage versus the flexibility to see any Medicare-accepting provider nationwide. The choice is rarely simple and depends on individual health status, provider preferences, travel patterns, financial circumstances, and risk tolerance.

This guide walks Georgia families through every aspect of Medicare Advantage: the federal framework and how it interacts with Original Medicare, the major plan types (HMO, PPO, PFFS, MSA, SNP), the enrollment periods including the Initial Coverage Election Period, the Annual Election Period (October 15 through December 7), the Medicare Advantage Open Enrollment Period (January 1 through March 31), and various Special Enrollment Periods, the CMS Star Ratings system, prior authorization and utilization management, the appeals process through five levels, supplemental benefits including the Special Supplemental Benefits for the Chronically Ill, Part D integration with the new $2,000 out-of-pocket cap, dual-eligible Special Needs Plans (D-SNPs), the comparison with Original Medicare plus Medigap, marketing rules and the 2024 broker compensation reforms, and the Georgia carrier landscape. We close with six worked examples, fifteen common MA enrollment mistakes, a comprehensive FAQ, and a contact list for Georgia families.

The Federal Framework: Section 1851 of the Social Security Act

The statutory foundation of Medicare Advantage is Section 1851 of the Social Security Act, codified at 42 USC 1395w-21. This section establishes the core framework: Medicare-eligible beneficiaries can choose to receive their Medicare Part A and Part B benefits through Original Medicare directly or through a private Medicare Advantage plan that contracts with CMS to provide those benefits (plus often Part D and supplemental benefits) on a capitated payment basis.

Medicare Advantage replaced the prior Medicare+Choice program established under BBA 1997 (PL 105-33) Title IV. MMA 2003 (PL 108-173) renamed M+C to Medicare Advantage, integrated Part D prescription coverage into MA plans (creating MA-PD), and substantially increased payments to MA plans. MIPPA 2008 (PL 110-275) strengthened consumer protections. The ACA 2010 (PL 111-148) added the Star Ratings authority under Section 1853(o), restructured MA payment rates, and imposed medical loss ratio (MLR) requirements. The Bipartisan Budget Act 2018 (PL 115-123) expanded Value-Based Insurance Design demonstrations and authorized Special Supplemental Benefits for the Chronically Ill. The Inflation Reduction Act 2022 (PL 117-169) introduced the $2,000 Part D out-of-pocket cap effective 2025, capped insulin at $35/month, eliminated cost-sharing for ACIP-recommended vaccines, and authorized Medicare drug price negotiation.

The implementing regulations at 42 CFR Part 422 cover every aspect of MA operations: eligibility and enrollment (42 CFR 422.50-422.84), benefits and beneficiary protections (42 CFR 422.100-422.114), provider network requirements (42 CFR 422.200-422.272), and grievances and appeals (42 CFR 422.560-422.626).

Medicare Advantage Plan Types

HMO (Health Maintenance Organization)

HMOs are the most common Medicare Advantage plan type in Georgia. Key features:

• Beneficiary must use in-network providers (with exceptions for emergency and urgent care)
• A Primary Care Physician (PCP) is required and acts as gatekeeper
• Specialist visits typically require a PCP referral
• Premiums are the lowest among MA plan types, often $0
• Comprehensive supplemental benefits common (Part D, dental, vision, hearing, fitness, OTC)

HMOs work best for beneficiaries who:

• Have a stable PCP relationship
• Are willing to use in-network providers
• Have predictable health needs
• Want low monthly costs

PPO (Preferred Provider Organization)

PPOs offer more provider flexibility than HMOs:

• Can use in-network providers at lower cost-sharing
• Can use out-of-network providers at higher cost-sharing
• No PCP requirement
• No specialist referrals needed
• Higher premiums than HMOs (often $20-$60/month)
• Better suited for snowbirds, travelers, and those wanting provider flexibility

PFFS (Private Fee-for-Service)

PFFS plans allow beneficiaries to see any provider who accepts the plan's payment terms:

• Provider must agree to accept the plan's payment for each visit
• Less common in Georgia than HMO or PPO
• Premiums vary
• May or may not include Part D

MSA (Medical Savings Account)

MSA plans combine a high-deductible MA plan with a savings account:

• CMS deposits funds into the MSA annually
• Beneficiary pays out of the MSA until the deductible is met
• After deductible, plan covers in-network services
• Rare in Georgia market
• Cannot include Part D (must enroll in standalone PDP)

Special Needs Plans (SNPs)

SNPs are specialized MA plans for specific populations under Section 1859 SSA:

• D-SNP (Dual Eligible SNP) : for beneficiaries with both Medicare and Medicaid
• C-SNP (Chronic Condition SNP) : for beneficiaries with specific chronic conditions (diabetes, cardiovascular disease, etc.)
• I-SNP (Institutional SNP) : for beneficiaries in nursing facilities or who would qualify for institutional level of care

FIDE-SNP and HIDE-SNP

For dual-eligibles, two integration tiers exist:

• FIDE-SNP (Fully Integrated Dual Eligible SNP) : comprehensive Medicare-Medicaid integration with the same organization providing both benefits
• HIDE-SNP (Highly Integrated Dual Eligible SNP) : partial integration with the MA carrier also operating a Medicaid managed care plan

Both grew out of MIPPA 2008 and ACA 2010 dual-eligible integration efforts and have expanded substantially in Georgia for dual-eligible beneficiaries.

Enrollment Periods

Initial Coverage Election Period (ICEP)

The ICEP for Medicare Advantage aligns with the Medicare IEP. It is a 7-month window beginning 3 months before the month of 65th birthday (or month of Medicare eligibility for disability cases) and ending 3 months after. Beneficiaries can enroll in an MA plan during their ICEP with coverage effective the first of the month following enrollment (after their Medicare effective date).

Annual Election Period (AEP)

The AEP runs October 15 through December 7 each year under Section 1851(e)(3). During AEP, beneficiaries can:

• Switch from one MA plan to another
• Switch from MA back to Original Medicare
• Switch from Original Medicare to MA
• Enroll in, change, or drop a Part D plan

All AEP elections are effective January 1 of the following year. The AEP is the most important annual decision point for Medicare beneficiaries because plan benefits, networks, formularies, and premiums can change each year.

Medicare Advantage Open Enrollment Period (MA-OEP)

The MA-OEP runs January 1 through March 31 each year under Section 1851(e)(2)(C). This period is available only to beneficiaries who were enrolled in MA on January 1 and allows one of the following changes:

• Switch from one MA plan to another
• Switch from MA back to Original Medicare with a Part D plan

Note that MA-OEP does NOT allow beneficiaries in Original Medicare to switch to MA. That election can only be made during the AEP or a qualifying Special Enrollment Period.

Special Enrollment Periods (SEPs)

Several SEPs allow MA enrollment or plan changes outside the standard windows:

• Move outside service area: 2-month SEP from the move
• Lose creditable Part D coverage involuntarily: 2-month SEP
• Qualify for or lose Medicaid or Extra Help (LIS): various SEPs based on status changes
• 5-star plan SEP: December 8 through November 30 each year for switching to a 5-star plan
• Plan termination by CMS: 3-month SEP from the termination notice
• Significant plan changes: SEP for major changes to formulary, network, or benefits
• Disaster declaration SEP: for federal, state, or local disasters affecting the beneficiary
• Exceptional circumstances: case-by-case CMS determination

2024 Quarterly SEP for LIS-Eligible

Effective January 2024, CMS changed the SEP for LIS-eligible beneficiaries from monthly to quarterly for most categories. Full-benefit dual-eligibles retain a monthly SEP under most circumstances. This change was made to reduce plan switching driven by broker incentives rather than beneficiary needs.

CMS Star Ratings System

The CMS Star Ratings system under Section 1853(o) SSA was added by ACA 2010 and provides comparative quality information for Medicare Advantage plans.

How Star Ratings Work

Plans are rated 1 to 5 stars (with half-star increments) based on performance in five categories:

1. Staying healthy: preventive screenings, vaccines, annual wellness exams
2. Managing chronic conditions: diabetes care, blood pressure control, depression screening
3. Member experience with the plan: ease of getting care, customer service, plan information
4. Member complaints and plan performance: complaints, problems leaving the plan, member problems
5. Customer service: call center, language services, appeals timeliness

Each measure is scored independently, then weighted and combined for an overall plan rating. CMS publishes Star Ratings annually in October before the AEP begins.

Financial Implications for Plans

Star Ratings have major financial consequences for MA carriers:

• Plans rated 4+ stars receive Quality Bonus Payments (QBPs), increasing CMS reimbursement
• 5-star plans get a continuous enrollment period (December 8 through November 30) allowing year-round enrollment
• Plans below 3 stars for 3 consecutive years can be terminated by CMS
• Plans below 4 stars cannot prominently use Star Rating in marketing

How Georgia Beneficiaries Should Use Star Ratings

Star Ratings are an important but imperfect signal:

• Higher-rated plans tend to have better customer service and member experience
• Higher-rated plans often have richer benefits due to Quality Bonus Payments
• Star Ratings should be one factor among several (network, formulary, cost-sharing, supplemental benefits)
• Plans can change ratings year-over-year
• Medicare.gov plan finder displays Star Ratings prominently

In Georgia in 2026, many MA plans are rated 4 stars or higher, with a stronger concentration of high-rated plans in the Atlanta metro area.

Prior Authorization and Utilization Management

Medicare Advantage plans use prior authorization (PA) to control costs and ensure medical necessity. The PA framework is governed by 42 CFR 422.566 and surrounding provisions.

Common Prior Authorization Targets

• Specialty drugs and oncology therapeutics
• Advanced imaging (MRI, CT, PET)
• Inpatient hospital admissions
• Skilled nursing facility stays beyond initial period
• Home health services
• Durable Medical Equipment (DME)
• Behavioral health services
• Some specialist referrals

2024 CMS Final Rule on Prior Authorization

CMS finalized new prior authorization rules effective 2024:

• Standard determinations: 7 calendar days (reduced from 14)
• Expedited determinations: 72 hours (unchanged)
• Plan must provide written notice of decision
• Approval valid for the duration of the prescribed course of treatment
• Plans must publicly report PA metrics

How to Navigate Prior Authorization

For Georgia beneficiaries facing prior authorization issues:

• Work with the provider to submit complete documentation
• Request expedited determination if delay would jeopardize health
• File reconsideration if PA is denied
• Escalate to Independent Review Entity (IRE) if reconsideration denied

Appeals Process

The Medicare Advantage appeals process has five levels under 42 CFR 422.578-422.626:

Level 1: Plan Reconsideration

The first level is a reconsideration by the MA plan itself:

• Standard reconsideration: 30 days
• Expedited reconsideration: 72 hours (when delay would jeopardize health)
• Plan must provide written notice of decision

Level 2: Independent Review Entity (IRE)

If the plan upholds its denial, the case is automatically forwarded to Maximus, the CMS-contracted IRE:

• Standard IRE review: 30 days
• Expedited IRE review: 72 hours
• IRE is independent of the MA plan

Level 3: Administrative Law Judge (ALJ) Hearing

If the IRE upholds the denial, beneficiaries can request an ALJ hearing:

• Amount-in-controversy threshold applies (verify current year threshold via CMS)
• Hearing typically conducted by telephone or video
• Beneficiary can be represented by attorney or advocate

Level 4: Medicare Appeals Council (MAC)

If the ALJ decision is unfavorable, beneficiaries can request MAC review:

• MAC is the final administrative review level
• Decision is generally based on written record

Level 5: Federal District Court

The final option is judicial review in federal district court:

• Amount-in-controversy threshold applies (verify current year threshold via CMS)
• Most common when major coverage denials affect significant medical costs

Expedited vs. Standard Appeals

Throughout the appeals process, expedited timelines apply when delay would jeopardize:

• Life or function
• Ability to regain maximum function

Beneficiaries should specifically request expedited review when applicable and explain why standard timelines would cause harm.

Supplemental Benefits

One of the most attractive features of Medicare Advantage for Georgia seniors is supplemental benefits not available through Original Medicare.

Traditional Supplemental Benefits (Section 1852(a)(3))

Standard supplemental benefits offered by most Georgia MA plans:

• Routine vision exams and eyewear allowance
• Routine dental cleanings, exams, and procedures
• Routine hearing exams and hearing aid coverage
• Fitness programs (SilverSneakers, Renew Active)
• Over-the-counter (OTC) benefit allowance
• Transportation to medical appointments
• Wellness programs

Special Supplemental Benefits for the Chronically Ill (SSBCI)

Added by the Bipartisan Budget Act 2018, SSBCI benefits are available to beneficiaries with chronic conditions:

• Meal delivery (especially post-discharge)
• Transportation beyond medical
• Healthy food allowances
• In-home support services
• Pest control
• Home air filters
• Adult day care

SSBCI benefits must have a reasonable expectation of improving or maintaining health.

Value-Based Insurance Design (VBID)

Some Georgia plans participate in the VBID demonstration, which allows targeted benefit reductions or enhancements based on health status. Examples:

• Reduced cost-sharing for specific medications for diabetic enrollees
• Enhanced behavioral health benefits for high-risk enrollees
• Targeted transportation for specific care needs

Part D Integration in MA-PD Plans

Most Georgia MA plans (about 90 percent) include Part D prescription drug coverage. These plans are called MA-PD plans. Standalone Part D Prescription Drug Plans (PDPs) are typically used by Original Medicare beneficiaries.

Important Rule

A beneficiary enrolled in MA-PD cannot also enroll in a standalone PDP. Enrolling in a PDP automatically terminates the MA-PD enrollment and returns the beneficiary to Original Medicare with the new PDP.

IRA 2022 Part D Changes

The Inflation Reduction Act 2022 made dramatic changes to Part D that apply to MA-PD plans:

2024:

• LIS Extra Help eligibility expanded for near-poverty beneficiaries under IRA 2022 (full subsidy extended to additional income levels)
• Elimination of cost-sharing in catastrophic coverage phase

2025:

• $2,000 annual out-of-pocket cap for all Part D beneficiaries (Section 11201 of IRA)
• Medicare Prescription Payment Plan (M3P) allowing beneficiaries to spread out-of-pocket costs across the calendar year
• Insulin capped at $35/month (already implemented 2023)
• ACIP-recommended vaccines at $0 cost-sharing (already implemented 2023)

2026:

• Negotiated prices effective for first 10 Medicare-selected drugs
• Continued OOP cap with annual indexing

The $2,000 OOP cap is particularly significant for Georgia beneficiaries with high prescription costs. Before 2025, beneficiaries in the catastrophic coverage phase still paid 5 percent coinsurance, which could mean $10,000+ in annual out-of-pocket costs for those on specialty drugs. The new cap provides predictable maximum exposure.

Comparison with Original Medicare + Medigap

Choosing between Medicare Advantage and Original Medicare with a Medigap supplement is one of the most consequential Medicare decisions. Here's the comparison framework.

Monthly Cost

Medicare Advantage typical:

• Part B premium: $202.90
• MA plan premium: $0-$50 (often $0)
• Part D included in MA-PD
• Total: $202.90-$252.90/month

Original Medicare + Medigap + Part D typical:

• Part B premium: $202.90
• Medigap Plan G: $130-$250
• Part D: $30-$50
• Total: $362.90-$502.90/month

Provider Network

Medicare Advantage:

• HMO: limited to plan network only
• PPO: in-network preferred, out-of-network at higher cost-sharing
• Network can change annually
• Provider must accept the specific plan

Original Medicare:

• Any Medicare-accepting provider nationwide
• No network restrictions
• Provider just needs to accept Medicare assignment

Prior Authorization

Medicare Advantage:

• Required for many services (specialty drugs, imaging, inpatient, SNF, home health, DME)
• Approval timelines: 7 days standard, 72 hours expedited
• Denials can be appealed through 5 levels

Original Medicare:

• Limited prior authorization (mostly Power Mobility Devices, hospital outpatient department services, some advanced imaging in demonstration)
• Most services covered without preapproval

Cost-Sharing Structure

Medicare Advantage:

• Predictable copays per service ($0-$50 for office visits, $90-$120 ER, $295-$395/day inpatient days 1-5)
• Annual out-of-pocket maximum ($9,250 in-network in 2026)
• Cost-sharing applies to most services until OOP max reached

Original Medicare + Medigap (Plan G):

• Part B deductible $283 (2026)
• All other Medicare cost-sharing covered by Plan G
• No OOP maximum needed because cost-sharing is fully covered

Supplemental Benefits

Medicare Advantage:

• Often includes dental, vision, hearing, fitness, OTC
• Benefits vary by plan
• Special supplemental benefits for chronically ill (SSBCI)

Original Medicare + Medigap:

• No dental, vision, hearing benefits (must be purchased separately)
• Foreign travel emergency covered by Plans G, F, C, D, M, N
• Predictable structure without annual benefit changes

Travel Coverage

Medicare Advantage:

• HMO: limited travel coverage (emergency and urgent care only out of area)
• PPO: out-of-network coverage at higher cost-sharing
• Some plans have limited international coverage

Original Medicare + Medigap:

• Coverage anywhere in the US
• Plan G, F, C, D, M, N include foreign travel emergency benefit
• Best for snowbirds and frequent travelers

Annual Plan Changes

Medicare Advantage:

• Plans can change benefits, networks, formularies, cost-sharing annually
• Must review during each AEP
• Carrier can discontinue plans

Original Medicare + Medigap:

• Stable structure (Medigap benefits federally standardized)
• Premiums increase but plan structure doesn't change
• Guaranteed renewability under Section 1882(c)(1)(D)

Marketing Rules and the 2024 Broker Compensation Reform

MA marketing is heavily regulated under the CMS Medicare Marketing Guidelines.

Key Marketing Prohibitions

• No cold calling (unless beneficiary has consented)
• No door-to-door without appointment
• No unsolicited contact with prospective enrollees
• Required Scope of Appointment (SOA) before broker meeting
• 48-hour cooling-off period for some marketing materials
• No misleading "savings" claims
• No improper use of Medicare, Social Security, or CMS branding

2024 Final Rule on Broker Compensation (89 Fed. Reg. 30448)

In April 2024, CMS finalized a rule addressing broker compensation:

• Capped commission disparities between carriers (so brokers wouldn't push specific plans for higher pay)
• Addressed "ad hoc" payment arrangements beyond standard commissions
• Required disclosure of all compensation
• Designed to reduce broker incentives to push specific plans

The rule was partially challenged in court and some provisions modified, but the core compensation transparency requirements remain.

Red Flags in Marketing

Georgia families should be wary of:

• Pressure to sign up immediately
• Promises that sound too good (e.g., "$2,000 cash back on your Social Security check")
• Marketing that doesn't disclose network restrictions
• Brokers who only represent one carrier
• Calls or visits without prior appointment
• Materials with prominent celebrity endorsements but limited plan information

Dual-Eligible Special Needs Plans (D-SNPs)

For Georgia beneficiaries with both Medicare and Medicaid, D-SNPs offer integrated coverage that combines benefits and care coordination across both programs.

D-SNP Benefits

• Typically $0 premium
• $0 cost-sharing for Medicare-covered services (consistent with Section 1902(n)(3)(B) QMB protection)
• Care coordination and case management
• Transportation to medical appointments
• Healthy food benefit (some plans)
• Enhanced dental, vision, hearing coverage
• OTC benefit allowance ($90-$200 per quarter typical)
• Some plans include adult day care or in-home support

Georgia D-SNP Landscape

Multiple carriers offer D-SNPs in Georgia:

• Humana Gold Plus D-SNP
• Anthem MediBlue Dual Advantage
• UnitedHealthcare Dual Complete
• Wellcare Dual Liberty
• Aetna Medicare Dual

These plans coordinate with Georgia DCH for Medicaid benefits and serve full-Medicaid + QMB enrollees and some other dual-eligible categories.

FIDE-SNP Advantage

Fully Integrated Dual Eligible SNPs offer the highest level of Medicare-Medicaid integration:

• Same carrier provides Medicare and Medicaid benefits
• Single integrated care plan
• Reduced administrative burden
• Best for beneficiaries with complex chronic conditions

Georgia Carrier Landscape

Major MA Carriers in Georgia (2026)

• Humana : largest MA presence in Georgia, strong in Atlanta and rural areas
• UnitedHealthcare (AARP) : second largest, comprehensive Georgia footprint
• Aetna (CVS Health) : significant Georgia presence
• Anthem Blue Cross Blue Shield of Georgia : strong in Atlanta metro
• Wellcare (Centene) : growing market share, focused on D-SNP and PDP
• Cigna : moderate Georgia presence
• Kaiser Permanente : limited Georgia footprint (Atlanta metro only, HMO model)
• Devoted Health : newer entrant with technology-forward approach
• Alignment Healthcare : growing presence in Atlanta metro

Plan Variety

In Atlanta metro counties, beneficiaries typically have access to a large number of MA plans. In rural Georgia counties, the choice is more limited. All Georgia counties have access to multiple HMO and D-SNP options. PPO availability is broader in metro areas.

Out-of-Pocket Maximums

Medicare Advantage plans are required to have annual out-of-pocket maximums under 42 CFR 422.100(f)(4).

Federal Minimums (2026)

• In-network OOP maximum: $9,250
• Combined in-network plus out-of-network OOP max (PPO plans): $14,000

Typical Plan OOP Maximums

Most Georgia MA plans offer OOP maximums below the federal ceiling:

• Premium plans: $3,500-$5,500
• Standard plans: $5,500-$7,500
• Budget plans: $7,500-$9,250

After reaching the OOP maximum, the plan covers 100 percent of remaining in-network cost-sharing for the year (other than premiums and out-of-network costs).

Worked Examples

Margaret 65 Atlanta: HMO with $0 Premium

Margaret retired from her teaching career at age 65 in October 2025. She is healthy with low expected utilization. Her PCP and most specialists practice within the Emory Healthcare system in Atlanta.

Margaret reviews MA options during her ICEP:

• Humana Honor HMO: $0 premium, $0 PCP, $40 specialist, $90 ER, includes Part D, dental, vision, hearing, fitness
• Network: 30,000+ Atlanta-area providers including Emory, Piedmont, Wellstar
• Star Rating: 4 stars
• OOP maximum: $4,500

Margaret enrolls effective November 1, 2025. Her annual cost estimate:

• Part B premium: $202.90 x 12 = $2,434.80
• MA plan premium: $0
• Estimated cost-sharing (4 PCP visits, 1 specialist, annual labs): $40
• Total: $2,475

Compared to Original Medicare + Plan G ($165) + Part D ($35) = $402.90/month x 12 = $4,834.80 + $283 Part B deductible = $5,117.80

Margaret saves approximately $2,643 in year one with the MA HMO. She accepts the network restrictions because her preferred providers are in network.

Robert 68 Savannah: PPO for Travel

Robert is a snowbird, spending 4 months/year in Florida and traveling extensively in the eastern US. He needs provider flexibility across multiple states.

Robert reviews PPO options:

• Aetna PPO: $35/month premium, $0 PCP, $40 specialist, $120 ER, $300/day inpatient days 1-5
• Out-of-network coverage available at higher cost-sharing
• Network: nationwide PPO with reciprocal arrangements
• Star Rating: 4.5 stars
• Includes Part D
• OOP maximum: $6,500 in-network, $12,000 combined

Robert enrolls. His annual cost estimate:

• Part B premium: $202.90 x 12 = $2,434.80
• MA plan premium: $35 x 12 = $420
• Estimated cost-sharing: $600
• Total: $3,455

Robert chose PPO over HMO specifically because his Florida winter location is far from his Georgia network. The PPO out-of-network coverage protects him during travel.

Linda 70 Macon: D-SNP

Linda is a full-Medicaid plus QMB enrollee with income of $1,100/month from Social Security. She has diabetes and hypertension requiring ongoing management.

Linda enrolls in Humana Gold Plus D-SNP during the dual-eligible quarterly SEP:

• $0 premium
• $0 cost-sharing for Medicare-covered services (QMB protection under Section 1902(n)(3)(B))
• Care coordinator assigned
• Transportation to medical appointments
• Healthy food benefit (for example, ~$190/month in some plans — verify current plan details)
• Annual dental benefit (for example, up to $1,500 in some plans — verify current plan details)
• OTC allowance (for example, ~$90/quarter in some plans — verify current plan details)
• Comprehensive medication management
• Diabetes care coordination

Linda's annual costs:

• Part B premium: $0 (paid by Georgia Medicaid through Section 1843 Buy-In)
• MA plan: $0
• Cost-sharing: $0 (QMB protection)
• Total: $0

Linda gains substantial supplemental benefits, care coordination, and integrated Medicare-Medicaid care at no out-of-pocket cost.

Charles 73 Augusta: Switches MA to Medigap

Charles enrolled in Anthem BCBS MA HMO at age 65 in 2018. Initially satisfied with the $0 premium and dental benefit, he is now diagnosed with a cardiac condition requiring a specialist at Emory University Hospital, which is out of his HMO network.

Charles realizes he wants Original Medicare + Medigap for provider choice. His options:

• AEP 2025 (October 15 - December 7): switch to Original Medicare effective January 1, 2026
• Medigap application: outside OEP, subject to medical underwriting in Georgia

Charles applies for Medigap Plan G during AEP. He is past the 12-month MA trial right (which is only available at first Medicare eligibility). Outside OEP, Georgia carriers can underwrite.

Charles applies to multiple carriers:

• AARP UnitedHealthcare: declined due to cardiac condition
• Anthem BCBS: declined
• Mutual of Omaha: approved at health-rated $275/month (vs. $185 standard)
• Cigna: declined

Charles enrolls in Mutual of Omaha Plan G at $275/month effective January 1, 2026. His new monthly costs:

• Part B premium: $202.90
• Plan G: $275 (health-rated)
• Part D: $42
• Total: $519.90/month

Higher cost than the MA HMO he left, but full provider choice and access to Emory cardiology.

Patricia 67 Columbus: Prior Auth Denial

Patricia is enrolled in UnitedHealthcare MA PPO. Diagnosed with HER2-positive breast cancer, her oncologist prescribes a specialty therapy (combination of pertuzumab + trastuzumab + chemotherapy).

The MA plan denies prior authorization for pertuzumab, citing step therapy requiring her to try a less expensive alternative first.

Patricia and her oncologist file expedited reconsideration with the plan, documenting:

• Her specific HER2-positive subtype
• NCCN guideline recommendations
• Why step therapy alternatives would not be appropriate
• Risk of delay to cancer outcomes

The plan reviews and upholds the denial after 72 hours.

Patricia's case is automatically forwarded to the Independent Review Entity (Maximus). Maximus reviews the medical necessity documentation, oncologist's clinical rationale, and NCCN guidelines.

Maximus overturns the plan's decision. The plan must approve pertuzumab immediately. Patricia begins therapy 14 days later than originally scheduled.

Henry 72 Athens: Star Rating Switch

Henry has been enrolled in Wellcare MA HMO for 3 years. The plan was 4 stars when he enrolled but has slipped to 3 stars. During AEP 2025, Henry uses the Medicare.gov plan finder to compare options.

Henry identifies a 4.5-star Humana plan with:

• Same $0 premium
• Lower copays ($0 PCP vs $15, $35 specialist vs $45, $90 ER vs $120)
• Same major hospital systems in network (Piedmont Athens Regional)
• Better dental ($2,000 vs $1,500)
• Better Star Rating quality measures

Henry switches during AEP effective January 1, 2026. His annual cost-sharing reduction is approximately $400 with improved quality measures.

The Star Rating signal worked as designed: comparative information helped Henry identify a better-value plan during AEP.

15 Common MA Enrollment Mistakes

1. Choosing based on premium alone without considering cost-sharing. A $0 premium plan can still cost thousands annually through copays.

2. Not checking provider network for current PCP and specialists. Switching plans without verifying network can disrupt continuity of care.

3. Not verifying drug coverage for current prescriptions. MA-PD formularies vary significantly. Drugs may require prior authorization or step therapy.

4. Assuming HMO and PPO have similar provider flexibility. HMO is highly restrictive; PPO has more flexibility at higher cost-sharing.

5. Missing the 12-month MA trial right window. Section 1882(s)(3) provides a one-time opportunity at first Medicare eligibility. Miss it and Medigap is subject to underwriting.

6. Not understanding prior authorization requirements. Many MA enrollees discover PA only when care is delayed. Review plan PA list before enrolling.

7. Ignoring Star Ratings. Higher-rated plans tend to have better customer service, member experience, and quality outcomes.

8. Falling for misleading TV advertising. Common ads promise "$2,000 cash back" or "all-in-one benefits" without disclosing network and prior auth restrictions.

9. Working with brokers who don't represent multiple carriers. Single-carrier brokers cannot provide unbiased comparison.

10. Not coordinating with Medicaid eligibility. Full-dual eligibles should consider D-SNPs for integrated coverage and supplemental benefits.

11. Forgetting that MA plan benefits and networks can change annually. Always review during AEP, even if you're satisfied with your current plan.

12. Not factoring in travel patterns. HMOs are restrictive for snowbirds and out-of-state travelers. PPO or Original Medicare may be better.

13. Confusing MA-OEP with AEP. MA-OEP (Jan-March) is only for existing MA enrollees. AEP (Oct-Dec) is the primary change period.

14. Not understanding that MA replaces (not supplements) Original Medicare. MA is your sole Medicare coverage. You don't have Original Medicare as backup.

15. Buying Medigap while enrolled in MA. Prohibited under Section 1882(d)(3) with up to $25,000 federal civil penalties per violation.

What is Medicare Advantage?

Medicare Advantage (Part C) is a private health plan alternative to Original Medicare. Under Section 1851 of the Social Security Act, private insurance carriers contract with CMS to provide Medicare Part A and Part B benefits (and often Part D and supplemental benefits) through capitated arrangements. In 2026, a majority of Georgia Medicare beneficiaries are enrolled in MA plans.

How is MA different from Original Medicare?

Original Medicare allows any Medicare-accepting provider nationwide with minimal prior authorization. MA uses network plans with restricted provider choice (HMO most restrictive, PPO more flexible) and significant prior authorization. MA typically has lower or $0 premium but exposes beneficiaries to copays and network restrictions.

What plan types are available?

Major MA plan types are HMO (most common, most restrictive), PPO (more flexibility, higher premiums), PFFS (less common), MSA (high-deductible with savings account, rare), and Special Needs Plans (SNPs) for specific populations like dual-eligibles (D-SNP), chronic conditions (C-SNP), or institutional settings (I-SNP).

When can I enroll in Medicare Advantage?

Initial Coverage Election Period (ICEP) aligns with the Medicare IEP (7 months around 65th birthday). Annual Election Period (AEP) runs October 15 through December 7. Special Enrollment Periods (SEPs) apply for various circumstances. MA Open Enrollment Period (MA-OEP) January 1 through March 31 allows one switch for existing MA enrollees.

What is the MA Open Enrollment Period?

MA-OEP runs January 1 through March 31 each year under Section 1851(e)(2)(C). It is available only to beneficiaries already enrolled in MA at the start of the year. You can make one switch: to another MA plan, or back to Original Medicare with Part D. You cannot switch from Original Medicare to MA during MA-OEP.

What are CMS Star Ratings?

The Star Ratings system under Section 1853(o) rates MA plans 1 to 5 stars based on quality measures across five categories: staying healthy, managing chronic conditions, member experience, complaints, and customer service. Higher-rated plans (4+ stars) receive Quality Bonus Payments allowing richer benefits.

What is prior authorization?

Prior authorization (PA) is a process where MA plans require approval before covering certain services or medications. Common PA targets include specialty drugs, imaging, inpatient admissions, SNF stays, home health, and DME. The 2024 CMS final rule reduced standard PA timelines to 7 days and maintains expedited PA at 72 hours.

How does the MA appeals process work?

Five levels of appeals: (1) plan reconsideration, (2) Independent Review Entity (Maximus) review, (3) Administrative Law Judge hearing (amount-in-controversy threshold applies — check current year), (4) Medicare Appeals Council review, (5) federal district court (higher amount-in-controversy threshold — check current year). Expedited timelines apply when delay would jeopardize health.

What supplemental benefits do MA plans offer?

Traditional benefits include vision, dental, hearing, fitness (SilverSneakers), OTC allowance, and transportation. Special Supplemental Benefits for the Chronically Ill (SSBCI) include meal delivery, healthy food, in-home support, pest control, and home modifications. Benefits vary by plan and can change annually.

What does the 2025 Part D OOP cap mean for MA-PD enrollees?

Under IRA 2022 Section 11201, effective 2025 all Part D beneficiaries (including those in MA-PD plans) have a $2,000 annual out-of-pocket maximum for prescription drugs. This dramatically reduces specialty drug costs which previously could exceed $10,000 annually. The cap is indexed for inflation in subsequent years.

What is a D-SNP?

A Dual Eligible Special Needs Plan is an MA plan specifically for beneficiaries with both Medicare and Medicaid. D-SNPs offer integrated Medicare-Medicaid coverage, typically $0 premium, $0 cost-sharing for Medicare services (consistent with QMB protection), care coordination, transportation, and rich supplemental benefits. Available in most Georgia counties.

Can I have both MA and Medigap?

No. Section 1882(d)(3) of the Social Security Act prohibits selling Medigap to Medicare Advantage enrollees with up to $25,000 federal civil penalties per violation. You must be in Original Medicare to use Medigap.

Can I switch from MA back to Original Medicare?

Yes, during the AEP (October 15 - December 7) or MA-OEP (January 1 - March 31). However, in Georgia, applying for Medigap after switching is subject to medical underwriting outside OEP (unless you qualify for the 12-month MA trial right at first Medicare eligibility).

What is the MA trial right?

The 12-month Medicare Advantage trial right under Section 1882(s)(3) applies to beneficiaries who enrolled in MA at their first Medicare eligibility. They can disenroll from MA within 12 months and purchase Medigap with guaranteed issue (no medical underwriting). This is a critical one-time opportunity.

Does MA cover travel outside the service area?

It depends on the plan type. HMOs typically cover only emergency and urgent care out of area. PPOs cover out-of-network at higher cost-sharing. Some plans have limited international emergency coverage. For frequent travelers, Original Medicare provides better coverage flexibility.

Are MA networks the same as Medigap?

No. MA plans have specific networks contracted by the carrier. Medigap works with Original Medicare and accepts any Medicare-accepting provider nationwide. This is the most important practical difference.

How do I compare MA plans?

Use the Medicare.gov plan finder. Compare premium, cost-sharing for typical services, drug coverage for your medications, network providers, Star Rating, and supplemental benefits. GeorgiaCares SHIP (1-866-552-4464) provides free unbiased comparison help.

What are the marketing rules?

CMS Medicare Marketing Guidelines prohibit cold calling, door-to-door without appointment, unsolicited contact, misleading "savings" claims, and improper use of CMS/SSA/Medicare branding. A Scope of Appointment (SOA) is required before broker meetings. The 2024 broker compensation rule capped commission disparities.

What is a FIDE-SNP?

A Fully Integrated Dual Eligible SNP is a D-SNP variant where the same carrier provides both Medicare and Medicaid benefits with comprehensive integration. Best for dual-eligibles with complex chronic conditions. Coordinates with Georgia DCH for Medicaid coverage. Available in several Georgia counties.

How much do MA plans cost?

Most Georgia MA plans have $0 premium beyond the standard Part B premium ($202.90 in 2026). Some PPO and SNP plans charge $20-$60 monthly premiums. Cost-sharing varies: typical office visit $0-$30, specialist $30-$50, ER $90-$120, inpatient $295-$395/day for days 1-5. Annual OOP maximum federal ceiling is $9,250 in-network in 2026.

Are MA plans regulated by the state?

Federal regulation under 42 CFR Part 422 is primary. Georgia Office of Insurance Commissioner provides limited state oversight, primarily for licensing and consumer complaints. The federal framework is comprehensive.

What is the difference between MA-PD and MA-only?

MA-PD plans include Part D prescription drug coverage in the MA plan. MA-only plans do not include Part D (beneficiary must enroll in a standalone PDP or have other creditable coverage). About 90 percent of Georgia MA plans are MA-PD.

Can I switch MA plans during the year?

Outside AEP and MA-OEP, switching generally requires a Special Enrollment Period (SEP). Common SEPs include moving outside service area, losing creditable coverage, qualifying for/losing Medicaid or LIS, plan termination, or disaster declarations. 5-star plans have a continuous enrollment period.

What if my MA plan denies a needed service?

File expedited reconsideration with the plan (decision in 72 hours if health is at risk). If denied, automatic forwarding to the Independent Review Entity (Maximus). Continue through ALJ hearing, MAC review, or federal court as needed. GeorgiaCares SHIP can help navigate appeals.

Where can I get help choosing an MA plan?

GeorgiaCares SHIP at 1-866-552-4464 provides free, unbiased Medicare counseling in all 159 Georgia counties. The Medicare.gov plan finder allows comparison of plans available in your ZIP code. Licensed brokers can also help but should represent multiple carriers. :::
