2027 Medicare Advantage Carrier Updates Agents Need Before AEP

The 2026 Medicare Annual Enrollment Period runs from October 15 through December 7, 2026. Elections made during this period generally begin January 1, 2027.

Independent agents must prepare for more than new premiums. Review carrier announcements, plan documents, provider networks, formularies, service areas, supplemental benefits, and Special Needs Plan requirements before recommending coverage.

Treat every carrier announcement as an initial summary. Confirm every local plan detail through approved carrier materials and CMS-approved information.

Start With the CMS 2027 Final Rule

Review the CMS Contract Year 2027 Medicare Advantage and Part D Final Rule before completing your 2027 Medicare agent training and client review process.

CMS confirmed several policy changes for contract year 2027.

The rule updates Medicare Advantage and Part D Star Ratings. CMS is removing 11 measures focused on administrative processes and adding a Part C Depression Screening and Follow-Up measure beginning with the 2027 measurement year and 2029 Star Ratings.

CMS is also codifying several Inflation Reduction Act changes to Part D. These changes include:

• Eliminate the coverage gap phase.

• Establish a reduced annual out-of-pocket threshold.

• Eliminate cost sharing after the catastrophic threshold.

• Incorporate the Manufacturer Discount Program.

• Update True Out-of-Pocket cost calculations and specialty-tier rules.

These changes affect how agents explain prescription coverage. Avoid using outdated “donut hole” explanations without describing the 2027 structure. Review each plan’s Evidence of Coverage and formulary for the exact deductible, cost-sharing stages, drug tiers, restrictions, and pharmacy requirements.

CMS also finalized new requirements for certain supplemental benefits. Plans must publicly post their plan-developed eligibility criteria for Special Supplemental Benefits for the Chronically Ill. Plans using benefit debit cards must electronically connect the card to covered items and services through real-time eligibility verification. Cards must be limited to the applicable plan year.

Do not assume that unused funds will carry forward. Do not assume that every member qualifies for every supplemental benefit. Confirm eligibility, covered items, geographic limitations, activation requirements, and expiration dates.

Use Carrier Announcements as Research Starting Points

Carrier announcements provide useful summaries of strategic priorities. They do not replace plan-specific documents.

For example, Humana’s 2026 Medicare Advantage announcement highlighted plan stability, dental, vision, hearing, preventive services, prescription coverage, market expansion, and Special Needs Plans.

Aetna’s 2026 Medicare Advantage announcement highlighted provider access, preventive care, supplemental benefits, prescription coverage, simplified plan names, and C-SNP and D-SNP expansion.

Use these announcements to identify the categories requiring review:

• Plan availability.

• County expansion or withdrawal.

• Premium and cost-sharing structure.

• Provider and pharmacy access.

• Drug coverage.

• Supplemental benefits.

• SNP eligibility and support.

• Member communication priorities.

Do not present a national announcement as proof of local availability. A carrier may describe a benefit that applies only to selected plans, counties, populations, or eligibility groups. Confirm the plan identification number, service area, benefit period, and applicable restrictions before discussing the benefit with a client.

Compare the ANOC With the Evidence of Coverage

Ask clients to provide their Annual Notice of Change. Use the ANOC to identify year-over-year differences. Use the Evidence of Coverage to confirm the complete contract terms.

Begin with the plan’s status. Confirm that the plan will operate in the client’s county for 2027. Check for non-renewal notices, service-area reductions, plan consolidations, and county exits.

Next, compare the following items:

• Monthly premium.

• Annual medical maximum out-of-pocket limit.

• Primary care and specialist cost sharing.

• Hospital and emergency care costs.

• Inpatient and outpatient service rules.

• Dental, vision, hearing, fitness, transportation, meal, and OTC benefits.

• Prescription deductible and cost-sharing stages.

• Drug tiers, prior authorization, quantity limits, and step therapy.

• Preferred pharmacies and mail-order requirements.

• Referral and authorization rules.

Pay special attention to benefits that the client uses frequently. A plan with a lower premium may create higher costs for a specialist, hospital, medication, or dental service. A plan with a larger OTC allowance may have a narrower provider network or more restrictive drug coverage.

Document the reason for each recommendation. Record the plan documents reviewed, the client’s providers and prescriptions, and the material differences discussed.

Verify Provider Networks and Pharmacies

Provider directories can change. Confirm participation in the current 2027 directory and verify the provider’s network status for the exact plan.

Check the client’s:

• Primary care provider.

• Specialists.

• Preferred hospital.

• Outpatient facilities.

• Behavioral health providers.

• Dialysis providers.

• Pharmacies.

Do not rely on a carrier’s general network page. A provider may participate in one plan but not another. A physician may appear in a directory while a specific location, hospital affiliation, or provider group does not participate.

Check whether the plan is an HMO, PPO, or another plan type. Explain referral requirements, out-of-network rules, authorization requirements, and potential cost differences. Tell clients that provider participation remains subject to change and that they should confirm network status before receiving care.

Review pharmacy networks with the same care. Identify preferred pharmacies, standard in-network pharmacies, mail-order options, and restrictions on specialty medications. Confirm whether the client’s current pharmacy remains available at the expected cost-sharing level.

Review Formularies Drug by Drug

Do not evaluate prescription coverage by plan name or premium alone.

Run every regular medication through the 2027 formulary when available. Confirm the drug name, dosage, quantity, tier, pharmacy network, prior authorization, step therapy, and quantity limits.

Review high-cost and maintenance medications first. Check insulin, anticoagulants, specialty drugs, cancer medications, inhalers, and medications used for chronic conditions. Confirm whether the plan requires a specific pharmacy or mail-order service.

Explain the 2027 Part D out-of-pocket structure using the plan’s approved materials. Do not promise a specific annual cost without reviewing the client’s medications, utilization, pharmacy selection, and plan rules.

Recheck prescriptions when a client reports a medication change. A plan comparison completed in October may require an update before enrollment.

Investigate Supplemental Benefit Changes

Supplemental benefits remain a major source of plan differences. Review the actual limits instead of comparing headline descriptions.

For dental benefits, verify preventive and comprehensive services, annual maximums, waiting periods, frequency limits, covered providers, and network requirements.

For vision and hearing benefits, verify exam frequency, eyewear allowances, hearing aid coverage, participating providers, and product limits.

For OTC, food, transportation, utility, and other allowance benefits, verify the dollar amount, distribution schedule, covered items, qualifying conditions, participating locations, card rules, and expiration date.

Review SSBCI eligibility carefully. CMS requires plans to make their plan-developed eligibility criteria publicly available for applicable benefits. A client may have a qualifying condition but still fail a plan’s documented eligibility requirements.

Do not describe an allowance as unrestricted cash. Do not assume that a benefit applies to every member, every county, or every plan option.

Check Special Needs Plan Changes

Review C-SNP, D-SNP, and I-SNP materials separately from general Medicare Advantage materials.

For C-SNPs, confirm qualifying chronic conditions, provider networks, specialist access, care-management requirements, and condition-related supplemental benefits.

For D-SNPs, confirm Medicare and Medicaid eligibility requirements, state-specific Medicaid alignment, integrated care features, service areas, and changes to food, transportation, utility, OTC, and care-coordination benefits.

For I-SNPs, confirm institutional eligibility, facility participation, care requirements, and applicable provider arrangements.

Check whether the carrier is expanding, reducing, or discontinuing an SNP in the client’s county. Confirm the exact plan contract and eligibility rules through approved 2027 carrier and CMS materials.

Avoid describing an SNP as automatically better for every beneficiary with a chronic condition or Medicaid eligibility. Compare the plan against the client’s providers, medications, eligibility status, and care needs.

Build a 2027 AEP Research Workflow

Create one comparison file for each market you serve. Add the following documents as carriers release them:

• Carrier announcement.

• 2027 ANOC.

• 2027 Evidence of Coverage.

• Summary of Benefits.

• Provider directory.

• Pharmacy directory.

• Formulary.

• Service-area information.

• SNP eligibility and benefit materials.

• CMS-approved marketing materials.

Complete carrier certifications and required Medicare agent training through your brokerage and carrier portals. Use Advocate Financial’s Certification Station and FFM training and certification guide to support preparation.

Create a deadline calendar for carrier certifications, product releases, AEP appointments, client reviews, enrollment submissions, and follow-up documentation.

Use a standard comparison worksheet. Include plan status, county, premium, MOOP, medical cost sharing, prescriptions, pharmacies, providers, supplemental benefits, SNP eligibility, and key restrictions.

Update the worksheet when a carrier releases revised materials. Archive the version used for each client recommendation.

Confirm Before You Recommend

The most important 2027 Medicare Advantage carrier updates are the changes that affect a specific client’s coverage.

Confirm local plan availability. Confirm provider and pharmacy participation. Confirm formulary placement. Confirm supplemental benefit eligibility. Confirm SNP requirements. Confirm the plan’s approved materials and effective dates.

Use carrier announcements from Humana and Aetna as examples of how carriers communicate broad priorities. Use the CMS 2027 final rule for confirmed regulatory context.

Treat every local 2027 benefit, network, formulary, service area, premium, and plan availability detail as subject to verification through approved carrier and CMS materials.
