2027 Medicare Plan Review: ANOC, Drug Costs, and Provider Checklist

An automatic Medicare plan renewal does not guarantee that next year’s provider network, prescription coverage, or out-of-pocket costs will match this year’s terms. A premium can stay nearly the same while a doctor leaves the network, a medication moves to a different tier, a prior-authorization rule changes, or the cost at your preferred pharmacy goes up. That is why a useful fall review starts with your current plan’s change notice and your own health-care needs—not with a new plan’s advertising.

Medicare Open Enrollment runs every year from October 15 through December 7. During this period, you may be able to join, drop, or switch a Medicare Advantage or Medicare drug plan, or change between Original Medicare and Medicare Advantage. When the plan receives an enrollment request by December 7, the new coverage generally starts January 1. Even if you expect to keep your plan, checking next year’s costs, network, and drug list can prevent unpleasant surprises after the calendar changes.

This guide provides general information and an organizational framework for U.S. Medicare consumers. It is not individualized insurance, medical, legal, tax, or financial advice. Eligibility and the interaction among Medicare, employer coverage, Medicaid, military or retiree benefits, and Medigap depend on individual circumstances. Confirm a final decision with Medicare, the plan, your providers, your pharmacy, or a free State Health Insurance Assistance Program (SHIP) counselor.

Start with your records, not the advertisements

Your current plan card and Medicare card: Use your Medicare number only through verified official channels. Do not share it with an unexpected caller.
The Annual Notice of Change (ANOC) and Evidence of Coverage (EOC): These documents identify important changes in costs, benefits, networks, and drug coverage.
A complete medication list: Record the drug name, dosage, quantity, refill frequency, preferred pharmacy, and whether you use mail order.
A provider and facility list: Include primary care, specialists, hospitals, labs, rehabilitation centers, dialysis facilities, and other services you rely on.
Your actual spending: Look beyond premiums to copays, coinsurance, deductibles, prescription costs, transportation, and unexpected bills.
Likely changes next year: Note planned procedures, a new specialist, a move, extended travel, retirement, an end to employer coverage, or a possible new prescription.

This worksheet is a decision tool, not a document you need to circulate. Rather than leaving photos of cards and account numbers in an unsecured phone gallery, transfer only the details needed for comparison and store originals safely. If you are organizing insurance, identity, and financial documents together, the emergency financial records kit offers a practical backup framework.

Step 1: Read the ANOC as a list of changes

You do not need to memorize every line of the ANOC. The goal is to identify what will be different and translate those changes into effects on your care. If you cannot find the mailed copy, check the plan’s member portal or call verified customer service. Use the number on your current card or contact information confirmed through Medicare.gov instead of clicking a sponsored result that merely resembles the plan.

Review the document in this order:

Confirm that the plan will still operate in your service area and note any plan-name change.
Mark changes to the monthly premium, annual deductible, service-specific copays or coinsurance, and maximum out-of-pocket limit.
Find new provider, hospital, pharmacy, referral, prior-authorization, or step-therapy rules.
For dental, vision, hearing, transportation, over-the-counter, or fitness benefits, review eligibility, frequency, vendors, and limits—not just the benefit label.
Compare formulary and drug-tier changes against your medication list.
Write down the page number and a specific question for anything that is unclear, then ask the plan or a SHIP counselor.

Do not highlight only the items that went down. A lower premium may be outweighed by higher specialist copays, imaging coinsurance, outpatient surgery costs, or a higher maximum out-of-pocket limit. The reverse can also be true: a somewhat higher premium may produce a lower realistic annual cost if your doctors, hospitals, drugs, and pharmacy remain accessible. Compare the whole year under your likely pattern of care.

Step 2: Build annual cost scenarios instead of chasing one premium

One of the most common comparison errors is deciding from a single attractive number, such as a “$0 plan premium.” Even when a Medicare Advantage plan charges no additional premium, members generally continue paying the Part B premium and may owe deductibles, copays, and coinsurance as they use care. Because plan designs differ, avoid unverified national averages. Use your Plan Compare results, Summary of Benefits, and EOC.

Create four simple scenarios:

A low-use month: Premiums plus routine prescriptions.
Your normal year: Primary care, specialists, recurring tests, and current prescriptions at roughly your recent frequency.
A high-use year: Add imaging, outpatient surgery, rehabilitation, or more specialist visits.
Travel or moving: Account for extended time outside the service area and the possibility of nonemergency care away from home.

For each one, add 12 months of premiums, applicable medical deductibles, likely medical cost sharing, and prescription expenses. This does not predict the future; it exposes how each plan distributes risk. Do not assume that every expense, including prescription spending, automatically counts toward a Medicare Advantage medical maximum out-of-pocket limit. Check the official plan documents for what is included.

Step 3: Enter every prescription accurately

Medicare-approved private plans provide Part D coverage, and each plan can differ in cost and in the specific medications it covers. Search results can change based on generic versus brand name, dosage, tablet or capsule, quantity, 30-day versus 90-day supply, and pharmacy. Enter information directly from the prescription label rather than from memory.

List the exact name and dosage of every prescription.
Include as-needed medications using your past year’s realistic frequency.
Compare your preferred pharmacy with at least one practical alternative.
If you use mail order, review automatic refills, delivery timing, and temperature-sensitive handling.
Record formulary status, tier, prior authorization, quantity limits, and step therapy.
Review the month-by-month estimate so you can see how costs may differ before and after a deductible applies.

Do not assume that a covered drug will remain covered next year or that every store in the same pharmacy chain has identical preferred-network status. If a drug is missing or restricted, do not stop it on your own. Ask the prescriber and plan about a clinically appropriate alternative, a formulary exception, prior authorization, or a transition process. A lower cost does not make a medication medically interchangeable; that decision belongs with the treating clinician.

Step 4: Verify the exact provider, location, and network

Medicare Advantage network rules vary by plan type. HMO members generally use network providers and facilities, and referrals may be required. PPO members may be able to go out of network but can pay more. Medicare also notes that Advantage plans typically require prior authorization for certain services or supplies.

A name appearing in an online directory is only the beginning. One clinician can work at several addresses, and contracts can vary even within a hospital system. Verify all four of these details:

The provider’s full name and exact practice address
The complete official plan name and relevant contract or plan identifiers
Network participation for the year when the appointment will occur
Whether the practice is accepting new patients and whether a referral is required

Check the plan directory and then call the provider’s office to cross-check. “Do you take Medicare?” is not specific enough. Ask, “Will this clinician at this address be in network for this exact plan next year?” Record the date and the department that answered without collecting unnecessary personal details about the representative. For a planned procedure, separately check the surgeon, facility, anesthesia, imaging, durable medical equipment, and rehabilitation providers.

Step 5: Compare the structure of Original Medicare and Medicare Advantage

Neither structure is best for everyone. Original Medicare generally offers broad access to U.S. providers that accept Medicare, but you may need to evaluate separate Part D coverage and Medigap. Medicare Advantage delivers Part A and Part B benefits through a private plan and may bundle drug coverage and extra benefits, but its network, prior-authorization, and service-area rules deserve close review.

If you are considering a move from Medicare Advantage to Original Medicare, do not assume you can automatically buy any Medigap policy afterward. Medigap availability, effective dates, possible medical underwriting, and guaranteed-issue rights can depend on when you first enrolled, your coverage history, state law, and specific circumstances. Before dropping Advantage coverage, ask a Medigap carrier, your state insurance department, or SHIP to confirm whether you can enroll and when coverage would start. If you need prescription coverage after returning to Original Medicare, compare a separate Part D plan on the same timeline.

Step 6: Value extra benefits by their usable terms

Dental, vision, hearing, fitness, transportation, meal, and over-the-counter benefits may be useful, but a broad advertising label does not reveal their practical value. Check annual caps, cost sharing, approved vendors, authorization, frequency limits, geographic restrictions, and whether unused amounts roll over. Do not add an advertised allowance to your savings as if it were cash when you are unlikely or unable to use it.

If dental coverage matters, ask:

Are preventive services handled differently from crowns, dentures, or other major work?
Is your dentist in network, and is out-of-network billing covered?
What annual limit and service-frequency limits apply?
Does a treatment plan require prior authorization or a pre-service estimate?
Must you use a separate card, vendor, or platform?

A reduction in an extra benefit can be disappointing, but decide separately whether that benefit outweighs access to essential medications and clinicians. A useful priority order is: medically necessary care and drugs, an affordable worst-case risk, services you regularly use, and then optional extras.

Step 7: Check cost-help programs and free counseling through official channels

If premiums or medication costs are difficult to manage, do not begin by giving personal information to an unsolicited caller promising “new benefits.” Medicare provides official pathways to state programs that may help with Medicare costs, prescription costs, and Medicaid coordination. Eligibility varies with income, resources, location, and coverage status, so do not rely on an unverified benefit amount or assume automatic qualification.

The State Health Insurance Assistance Program is a publicly supported network offering free, individualized Medicare counseling to beneficiaries and families. SHIP is different from an insurance agent selling a plan. It can be particularly helpful when you need a neutral comparison or when Medigap, employer insurance, Medicaid, or retiree coverage makes the decision more complicated. Bring your ANOC, medication list, provider list, and written questions.

If a message claims that a government payment or benefit is waiting, follow the eight-step government payment verification checklist: avoid the message’s link or phone number and independently navigate to the agency’s official site. Do not give an unexpected caller your Medicare number, banking information, or payment.

Step 8: Work through realistic examples

Example A—a person taking several monthly prescriptions: The current plan has a low premium, but one medication will move to a different tier and the preferred pharmacy arrangement will change. Enter the exact dosage and 90-day quantity in Plan Compare, then compare the current pharmacy with a practical alternative. Ask the prescriber whether a clinically appropriate alternative exists. The annual drug estimate and restrictions may matter more than the premium difference.

Example B—a person planning knee surgery: Confirming the primary-care clinician and orthopedic surgeon is not enough. Check the surgical facility, anesthesia provider, imaging, brace or other equipment, postoperative rehabilitation, and physical therapy. Use the EOC to distinguish outpatient from inpatient cost sharing and ask whether each anticipated step requires prior authorization.

Example C—a seasonal resident: Review how routine, nonemergency care and prescriptions work during several months in another state. Do not assume the word “PPO” means every out-of-state appointment has the same cost. Compare out-of-network rules, service-area terms, any travel program, mail-order medication, and pharmacy access against the actual travel calendar.

The goal is not to endorse a particular plan. It is to replace “Is this a good plan?” with questions that can be verified: “Is this hospital address in network next year?” “What is the estimated cost before and after the deductible for a 90-day supply of this dosage at this pharmacy?” “Does this imaging service need prior authorization?”

Step 9: Save proof after you enroll

Use the official Medicare.gov Plan Compare tool or a plan or Medicare contact method you independently verified.
On the final screen, confirm the official plan name, coverage year, drug-coverage status, premium, and important cost sharing.
Store the submission date, confirmation number, and enrollment receipt or mailed proof securely.
Do not independently cancel existing coverage unless official instructions say that is necessary. A premature cancellation can create a gap.
When the new card and member materials arrive, check the name, address, and plan information and report errors promptly.
Before January appointments or refills, verify the new card, pharmacy, referrals, and prior authorizations.

If you enroll by phone, verify the number instead of trusting caller ID. End the call if someone threatens that Medicare will be canceled unless you pay immediately, asks for gift cards, cryptocurrency, or a wire transfer, or pressures you to reveal your full Medicare number. Call 1-800-MEDICARE or use the verified number on your card or Medicare.gov.

Ten common mistakes

Assuming automatic renewal means every term stays the same
Comparing premiums while ignoring deductibles, service costs, and maximum out-of-pocket exposure
Entering drug names without accurate dosage, quantity, and pharmacy information
Treating “accepts Medicare” as proof of participation in a specific Advantage network
Checking the hospital but not anesthesia, imaging, equipment, or rehabilitation providers
Valuing an advertised extra benefit as cash without reading its conditions
Assuming Medigap will be immediately available without conditions after leaving Advantage
Canceling the old plan before confirming the correct enrollment process
Mistaking a sales mailer or sponsored search result for an official government notice
Failing to save the confirmation number and effective date

Your final 30-minute checklist

□ I have the current plan’s ANOC and EOC.
□ I marked next year’s premium, deductibles, key copays or coinsurance, and maximum out-of-pocket limit.
□ I entered every drug’s name, dosage, quantity, and at least two accessible pharmacies.
□ I cross-checked next year’s network for primary care, specialists, hospitals, and planned facilities.
□ I reviewed prior authorization, referrals, quantity limits, and step therapy.
□ I evaluated extra benefits using actual limits and usage rules.
□ I confirmed coordination with employer, Medicaid, military, or retiree coverage when relevant.
□ If I need Medigap, I confirmed availability and an effective date before changing coverage.
□ I am enrolling through Medicare.gov or independently verified official contact information.
□ I saved the submission date, confirmation number, and a January follow-up reminder.

Frequently asked questions

If I do nothing, will my current plan remain unchanged?

Your enrollment may renew if the plan continues in your area and you remain eligible, but its costs, network, formulary, and extra benefits can change. Read the ANOC and EOC. If a plan ends or changes its service area, follow the official notice because different rights or enrollment periods may apply.

When is Open Enrollment, and when does a change start?

Medicare Open Enrollment runs from October 15 through December 7 every year. When the plan receives the request by December 7, coverage generally starts January 1. Special Enrollment Periods and other coverage circumstances follow separate rules.

Can I switch from one Medicare Advantage plan to another?

Yes, during the annual Open Enrollment period. People already enrolled in Medicare Advantage also have a Medicare Advantage Open Enrollment Period from January 1 through March 31, but the permitted actions are not identical to the fall period. Check Medicare’s official guidance for your situation.

My doctor says they accept Medicare. Do I still need a network check?

Yes. Participation in Original Medicare is not the same as in-network status for a specific Medicare Advantage plan. Confirm the complete plan name, exact practice address, and next year’s status with both the plan and the provider.

If my drug leaves the formulary, should I stop taking it?

No. Stopping or changing a prescription without clinical guidance may be dangerous. Ask the plan and prescriber about alternatives, an exception request, prior authorization, or transition procedures. Tell the plan promptly if you face an urgent refill problem.

Where can I get free help if the comparison is overwhelming?

Use 1-800-MEDICARE, Medicare.gov, or your local SHIP. SHIP offers free counseling to Medicare beneficiaries and families. Prepare your plan documents, medication list, provider list, and questions before the appointment.

How should I verify a caller who wants to change my plan?

Do not give the caller your Medicare number, bank information, or payment. End the call, then independently contact Medicare or the plan through Medicare.gov, 1-800-MEDICARE, or a verified number on your card. Pressure, cancellation threats, and demands for gift cards, transfers, or cryptocurrency are warning signs.
