Choosing Medicare for a Parent: Your 2026–2027 Checklist

Helping a parent choose Medicare coverage starts with five checks: confirm what coverage they already have, list their doctors and prescriptions, set a realistic monthly budget, understand the two main coverage paths, and get the legal permission needed to talk to Medicare on their behalf. Doing these first prevents the most common mistakes, like enrolling in a plan that drops a longtime doctor or skipping a deadline that triggers a lifetime penalty.

Before the Medicare work begins, one quick note for you as the helper: if you are also reviewing your own family’s finances, life insurance such as guaranteed universal life rates is a separate coverage and budgeting decision unrelated to your parent’s Medicare enrollment. It has no bearing on which Medicare plan your parent picks, but it is often worth pairing the two conversations while the family is already gathered around the paperwork.

Start with what your parent already has

Ask whether your parent already has coverage that works with Medicare. This single question changes everything. Common situations include:

• Employer or retiree coverage from a current or former job. Many people can delay Part B without penalty while covered this way, but the rules depend on the employer’s size and plan design, so confirm with the benefits office before any Medicare decision.
• Medicaid or a Medicare Savings Program. These state programs can pay premiums, deductibles, and copays for people with limited income and resources. For example, in 2026 the Qualified Medicare Beneficiary program has monthly income limits of $1,350 for an individual and $1,824 for a married couple, and states may use higher limits; if your parent qualifies for QMB, providers are not allowed to bill them for Medicare cost-sharing (Medicare Savings Programs).
• Veterans or federal benefits. VA health care, TRICARE, CHAMPVA, and federal retiree plans each coordinate with Medicare differently, which we cover below.
• A Medicare Advantage or drug plan already in force. If so, check the Annual Notice of Change that arrives each fall before assuming next year’s coverage matches this year’s.

If your parent is approaching 65 with no other coverage, timing matters. Signing up late for Part B can mean a penalty that lasts as long as they have Part B, and going 63 or more days without creditable drug coverage can trigger a Part D penalty (Medicare costs).

List the doctors, hospitals, and pharmacies that matter

Make a concrete list before comparing plans: every doctor your parent sees regularly, preferred hospitals, and the pharmacy they actually use. This list drives the biggest coverage trade-off.

Under Original Medicare, your parent can use any doctor or hospital in the U.S. that accepts Medicare; in most cases no referral is needed for a specialist. Under Medicare Advantage, your parent may need to use the plan’s network and service area for non-emergency care, may need referrals, and may need prior authorization for certain services (Compare Original Medicare & Medicare Advantage).

If your parent splits time between states, travels often, or sees specialists in another region, that flexibility difference may outweigh plan extras. Write down each doctor and call the office or check the plan directory to confirm participation before enrolling — directories change, so verify rather than assume.

List the medications and use the real numbers

Collect every prescription with its dose and pharmacy. Then run the plan comparison yourself: Medicare.gov’s plan finder lets you enter your parent’s drugs and get estimated monthly and annual drug costs for each plan in their area, and you can also look up Medigap premium ranges by ZIP code (Helpful tools). Do not guess from a plan’s headline premium; two plans with similar premiums can differ sharply once your parent’s actual drug list is entered.

Budget check — know these 2026 baseline numbers:

Source: Medicare costs. Medicare Advantage premiums, deductibles, and out-of-pocket limits vary by plan, and plans include a yearly out-of-pocket limit while Original Medicare has none unless your parent has supplemental coverage. Your parent will keep paying the Part B premium under either path.

Understand the two coverage paths

At this point it helps to compare your Medicare coverage options as a whole before drilling into any single plan: Original Medicare (Parts A and B, with a separate Part D drug plan and optional Medigap) versus Medicare Advantage (Part C), which bundles Parts A, B, and usually D through a private insurer (Your Medicare options, Medicare & You 2027).

The core decision is the Medigap and Medicare Advantage differences: Medigap fills the cost-sharing gaps of Original Medicare with broad provider access, while Medicare Advantage trades some network flexibility for an out-of-pocket limit and often extra benefits like vision, hearing, and dental. Match each path against your parent’s doctors, budget, and travel habits rather than choosing based on a single feature. One caution: annual open enrollment lets people switch Medicare Advantage or drug plans each year, but it does not generally guarantee a right to buy a Medigap policy without health underwriting, so a Medigap decision made at first eligibility deserves extra care.

How to shop, and who helps

Your parent can enroll through Medicare.gov, by phone with 1-800-MEDICARE, or with help from a licensed agent or the state’s free SHIP counseling program, which is not connected to any insurer (Helpful tools). Whether working with a broker or buying direct, the plan’s premium is the plan’s premium — agents are compensated by insurers rather than by charging the enrollee more — but a broker may only show the carriers and plans they represent, so ask which companies they can quote and cross-check the finalist plans on Medicare.gov’s finder. If your family prefers a fully independent second opinion, the local SHIP counselor can review the same options at no cost.

Handle permissions and paperwork before you need them

Medicare cannot discuss your parent’s claims or records with you without written authorization. The Authorization to Disclose Personal Health Information form (CMS-10106) gives 1-800-MEDICARE written permission to share information with the person your parent names; it can be submitted online through a Medicare.gov account or mailed in (Other Forms, CMS-10106). Your parent can also grant broader decision-making authority through a health care or financial power of attorney under state law — a document worth having in place regardless of which plan they choose.

When enrollment time nears, use a checklist for getting ready to enroll in Medicare so nothing is missed: Medicare card, birth date and citizenship or residency documentation, current coverage details, drug list, doctor list, and any employer or retiree plan information that affects Part B timing.

Special situations for veteran and military families

If your parent is a veteran, know that VA health care and Medicare are separate systems. VA recommends keeping other health insurance because VA generally does not pay for care received outside VA, and having Medicare can preserve access to community care (VA health care and other insurance). TRICARE For Life beneficiaries generally must have Medicare Parts A and B for it to pay as wraparound coverage (TRICARE For Life).

CHAMPVA is its own program — distinct from VA health care and from TRICARE — for certain family members of disabled or deceased veterans. Families coordinating CHAMPVA with Medicare coverage should confirm exactly how the two pay together before adding any additional policy, because the interaction determines whether extra coverage would pay anything at all (CHAMPVA care).

Federal retirees have another wrinkle: OMP administers the Federal Employees Health Benefits (FEHB) program, and coordination between FEHB and Medicare follows plan-specific rules, so check the plan brochure (OPM: Medicare for federal annuitants).

The bottom line

Choose in this order: confirm existing coverage, verify doctors and drugs against real plan data, price the full monthly cost including the Part B premium, decide between the Medigap path and Medicare Advantage, then handle authorization forms and enrollment paperwork. Recheck the numbers each fall, because plans and costs change annually. When you are ready to compare plans side by side using your parent’s actual doctors and prescriptions, a licensed agent can walk through the options with you — just be sure to also verify the finalists on Medicare.gov yourself.
