Know what changed in a plan before choosing for 2027.
Every fall, Medicare Advantage and Part D plans can change their premiums, drug coverage, provider networks, costs, and approval rules for the coming year. Whether you’re helping a parent or reviewing your own coverage, use this window to confirm the current plan still fits: or make a change for 2027 before December 7th.

The goal is not to switch
A plan can change its premiums, drug list, pharmacy arrangements, provider network, copays, and approval rules from one year to the next.
Keeping the current coverage is a completely valid outcome. The job is to make sure it still fits this person’s medications, doctors, expected care, and budget.
Start with the Annual Notice of Change
Medicare Advantage and standalone Part D plans send it each fall. It explains changes taking effect in January, including coverage, costs, provider networks, and the service area. If it did not arrive, ask the plan for another copy.
During October 15–December 7, the available choices depend on the person’s current coverage. Changes generally begin January 1. Before keeping or switching, use a possible high-cost year to test the plan’s weak spots.
Why Part D is here
Part D is Medicare drug coverage delivered by private plans. Standalone plans can be joined, dropped, or switched during this window.
Understand Part DMedigap uses different rules
Medigap is not part of annual Medicare Open Enrollment. Confirm the right to buy it before leaving Medicare Advantage.
Understand Medigap timingSwitch to another Medicare Advantage plan or return to Original Medicare. Before returning, confirm the need for a standalone Part D plan and eligibility to obtain Medigap.
Stress-test a high-cost year
Check the inpatient copay, rehabilitation rules, prior authorization, provider network, and yearly medical out-of-pocket limit.
Join, drop, or switch a standalone Part D plan, or choose a Medicare Advantage plan available locally.
Stress-test a high-cost year
Check exposure to another hospital benefit period, outpatient coinsurance, and repeated follow-up care. Original Medicare has no yearly out-of-pocket limit for Part A and Part B services.
Review Part D or choose Medicare Advantage, but remember that Medigap is not part of annual Medicare Open Enrollment. Do not drop a Medigap policy before confirming the consequences.
Stress-test a high-cost year
Confirm which hospital and outpatient costs the person’s Medigap plan letter covers—and whether its premium still fits the household budget.
This is a planning model, not a cost prediction. Compare the exact plan’s premium, hospital and outpatient cost sharing, drug costs, network, and approval rules. Medigap coverage also varies by plan letter.

Annual Medicare Open Enrollment runs October 15 through December 7. Changes generally begin January 1.
No. October 15–December 7 covers Medicare Advantage and Part D changes. Medigap has a separate six-month Open Enrollment Period that generally begins when someone is 65 or older and enrolled in Part B. Leaving Medicare Advantage for Original Medicare does not guarantee Medigap access. Outside a Medigap Open Enrollment Period, trial right, or other guaranteed-issue right, an insurer may use medical underwriting, charge more, or decline the application, depending on state law. Confirm Medigap eligibility and timing before leaving Medicare Advantage, and arrange Part D drug coverage if needed.
Medical underwriting is the insurer’s review of an applicant’s health history. Outside a protected enrollment or guaranteed-issue period, the insurer may use that information to decide whether to offer a Medigap policy and what to charge, subject to state law.
Sometimes. A federal trial right generally lets someone who dropped a Medigap policy to join Medicare Advantage for the first time return to the former policy within 12 months if the same insurer still offers it. If it is unavailable, certain other Medigap policies may be available. A separate trial right applies to someone who joined Medicare Advantage when first eligible for Medicare at 65 and returns to Original Medicare within the first year. Confirm the exact right and application deadline before switching.
No. A zero-dollar plan premium means no additional plan premium. A person generally still owes the Medicare Part B premium and may have deductibles, copays, coinsurance, and other plan costs.
Yes. Medicaid and Medicare Savings Programs may help eligible people pay Medicare premiums, cost sharing, prescriptions, or other care. Eligibility varies by state, and checking privately does not commit someone to changing coverage.
