As of October 8, 2026, Medicare Advantage members have a limited period to review 2027 coverage. Medicare Annual Enrollment runs from October 15 through December 7, 2026. Changes made during this period generally begin January 1, 2027.
At least 1 million people are expected to be affected by Medicare Advantage plan closures or reductions for 2027. The figure includes approximately 390,000 members in UnitedHealth plans that are shutting down and approximately 600,000 members in Humana plans being cut, according to reporting summarized by KFF Health News. Aetna and Centene are also reducing options in some areas.
The issue is not limited to plan availability. Provider networks, drug formularies, dental allowances, Part B givebacks, referrals, and maximum out-of-pocket limits may also change.
2027 Medicare Advantage Changes
According to Reuters, UnitedHealthcare and Aetna are narrowing provider networks and shifting more of their offerings toward HMO plans.
An HMO generally uses a defined network. Referrals may be required for certain specialists. Out-of-network care may not be covered except in limited situations, such as emergencies.
Networks reset each January 1. A doctor who accepted a plan in 2026 is not guaranteed to remain in that plan’s 2027 network. The carrier name alone does not establish network participation.
Federal data released during the week of September 28 showed plans eliminating broad networks of doctors and hospitals, reducing some benefits, and increasing certain out-of-pocket costs. KFF Health News reported that insurer announcements described the offerings as robust while the plan-level data showed reductions.
A Leerink Partners analysis of Medicare Plan Finder data, also reported by KFF Health News, identified several changes:
- UnitedHealthcare dental reductions affected approximately 70% of its members.
- Humana reduced or eliminated Part B givebacks for approximately 62% of members.
- CVS/Aetna reduced dental benefits for approximately 36% of members.
- Centene/Wellcare reduced dental benefits for approximately 45% of members and materially raised maximum out-of-pocket limits.
- Clover increased its maximum out-of-pocket limit by $1,144.
These figures are carrier-level findings. They do not determine the benefits or costs of a specific plan in a specific county.
CMS presents a different market summary. In its September 28 press release, CMS stated that the Medicare Advantage market is expected to remain stable. CMS projects approximately 34 million Medicare Advantage members in 2027 and reports that more than 99% of Medicare beneficiaries will have access to at least one Medicare Advantage plan.
Industry enrollment projections anticipate a decline of approximately 6% to 34 million members. CMS disputes the characterization of the market as unstable. Both statements can exist at the same time: broad national access may remain available while specific plans, networks, and benefits change substantially.
The projected averages also require qualification. The average Medicare Advantage premium is approximately $12 per month, and the average stand-alone Part D premium is approximately $36 per month. These are national averages. They are not estimates of what an individual will pay.
What the Change Means for One Medicare Member
Consider a 72-year-old Florida resident with a cardiologist, preferred hospital, and six regular prescriptions.
The member currently pays $22 per month for a 2026 Medicare Advantage plan. The 2027 Annual Notice of Change shows a $0 premium. The lower premium does not establish that the plan is less expensive overall.
The cardiologist may no longer be listed in the 2027 network. The hospital may be available only through a different plan or may require a different referral process. One prescription may move to a higher formulary tier. The maximum out-of-pocket limit may increase. The dental allowance may decrease.
The notice may also state that the current plan is terminating, being consolidated, or no longer available in the member’s county. In that situation, the member may need to select a replacement plan even if no voluntary plan change was requested.
The required review is specific:
- Confirm the 2027 monthly premium.
- Confirm the cardiologist, primary care physician, specialists, and hospital.
- Compare the full prescription list with the 2027 formulary.
- Review referral and prior authorization requirements.
- Compare the maximum out-of-pocket limit.
- Confirm the enrollment deadline.
The next action is to compare the exact 2027 plan and county in the Medicare Plan Compare tool, then confirm network information with each provider’s office.
Six-Step Check Before Enrolling

The following six-step sequence should be completed before a 2027 Medicare Advantage election.
1. Review the Annual Notice of Change
Open the Annual Notice of Change and locate the pages describing network, premium, benefit, and cost changes. The notice identifies whether the plan is renewing, being consolidated, or terminating.
A summary page may not contain every operational change. The Evidence of Coverage and 2027 provider directory may contain additional details.
2. Search the 2027 Provider Directory
Look up every doctor, hospital, clinic, and specialist used for routine or anticipated care. Search the 2027 directory for the exact plan name, not only the insurance company.
A provider listed for one plan from a carrier may not participate in another plan from the same carrier.
3. Call Each Doctor’s Office
Ask whether the office will accept the specific 2027 plan. The question should include the plan name and network name.
“Do you accept UnitedHealthcare?” is not sufficient. The correct question is whether the office will accept the specific 2027 Medicare Advantage plan being considered.
4. Re-Price the Full Drug List
Enter every prescription into the 2027 formulary comparison. Include dosage, frequency, quantity, pharmacy, and preferred mail-order option where applicable.
The review should identify formulary tiers, deductibles, quantity limits, prior authorization, step therapy, and pharmacy restrictions.
5. Compare the Maximum Out-of-Pocket Limit
Compare the 2027 maximum out-of-pocket limit with the current plan. A lower monthly premium may be paired with greater exposure when medical services are used.
Dental allowances and Part B givebacks should not be evaluated separately from the medical cost-sharing structure.
6. Confirm the Plan’s Status
Confirm whether the current plan is:
- Renewing without a material change.
- Renewing with a new premium or benefit structure.
- Being consolidated into another plan.
- Terminating in the county.
- Losing access to a specific network or service area.
The plan record, Annual Notice of Change, and carrier documents should be reviewed together.
Three Coverage Paths for 2027

Path One: Remain in the Current Plan
Remaining in the current plan may be appropriate when the plan is renewing, the doctors and hospital remain in network, prescriptions remain affordable, and the out-of-pocket limit is acceptable.
The absence of a plan change does not eliminate the need for review. Annual plan terms can change even when the plan remains available.
Path Two: Select Another Medicare Advantage Plan
A different Medicare Advantage plan may provide a better network, drug formulary, premium, or benefit structure.
Trade-offs may include a narrower HMO network, referrals, prior authorization, different hospital participation, and a different maximum out-of-pocket limit. A plan with a $0 premium can still create higher costs through deductibles, copayments, coinsurance, or uncovered out-of-network care.
Path Three: Original Medicare With Medigap and Part D
Original Medicare with a Medigap supplement and a stand-alone Part D plan may provide broader provider access because the member is not limited to a Medicare Advantage network in the same way.
This path generally involves separate premiums and may not include the same supplemental benefits offered by Medicare Advantage plans. Eligibility for Medigap can also depend on timing and underwriting rules.
Outside a protected enrollment period or trial right, an applicant may be subject to medical underwriting. Acceptance, pricing, or available Medigap options may therefore differ.
Timeline for the 2027 Coverage Decision
| Date | Event |
|---|---|
| October 15, 2026 | Medicare Annual Enrollment begins. |
| November 1, 2026 | Marketplace Open Enrollment begins for people who buy individual coverage before Medicare eligibility. |
| December 7, 2026 | Medicare Annual Enrollment ends. |
| December 15, 2026 | Marketplace deadline for January 1 coverage. |
| January 1, 2027 | 2027 Medicare plan year begins. |
| January 1–March 31, 2027 | Medicare Advantage Open Enrollment Period. One Medicare Advantage change is allowed. |
The Marketplace dates generally apply to people who are not yet eligible for Medicare and purchase their own coverage. They do not replace the Medicare Annual Enrollment deadline.
Questions for an Insurance Agent
Before signing an application, the following questions should be answered:
- Which plans are you appointed with?
- Can you show me the 2027 provider directory for my doctors?
- What is the 2027 maximum out-of-pocket limit?
- Does this plan require referrals?
- What tier is each of my prescriptions on?
- Are you paid differently depending on which plan I choose?
- Is this plan renewing, being consolidated, or terminating?
- Does the plan cover my preferred hospital and specialists?
- What prior authorization rules apply to my regular treatments?
An agent may not represent every plan available in a county. Appointment status should be confirmed for the carrier and plan being presented.
Finding an Insurance Agent Near Me and Verifying the License
Insurance licensing is issued by each state. There is no single national insurance license.
A Medicare-focused agent must hold an active health line of authority in the state where the application is being handled. Depending on the state and product, life and accident authority may also apply.
Each licensed producer has a National Producer Number, or NPN. The NPN is a permanent identifier used to distinguish the producer across state records. Consumers can use an NPN lookup or state insurance department lookup to confirm the person’s licensing record. License verification is free.
The license record should be checked for:
- Agent name.
- National Producer Number.
- State.
- Active or inactive status.
- Lines of authority.
- Carrier appointment for the company whose plan is being presented.
A Florida insurance agent directory or Texas insurance agent directory can be used as a research starting point. Additional state directories are available for Pennsylvania and Ohio.
For example, directory records list Robin Bales under NPN 8419273 and Marilee A. Roose under NPN 15489946. The records include Medicare-related categories and state licensing information. Current license and appointment status should still be confirmed with the applicable state records and carrier.
A VerifiedAgent directory profile is a research starting point. It is not proof of current licensure, appointment status, or plan availability.
The Main Risk Is Not the Headline Premium
In-network status is a one-year plan term, not a permanent promise. A provider’s 2026 participation does not establish 2027 participation.
When carriers reduce dental allowances or Part B givebacks to protect margins, the consumer’s exposure may shift to medical cost-sharing, the maximum out-of-pocket limit, and the cost of out-of-network care. The headline premium does not show that exposure.
The 2027 Medicare Advantage review should therefore be based on the complete plan record: network, formulary, referrals, prior authorization, benefits, premium, and maximum out-of-pocket limit.
Available records show significant plan-level variation. Current status may differ by carrier, plan, county, provider, and prescription. The selected coverage and agent license should be independently confirmed before December 7, 2026.
