Will My Doctor Still Take My Plan Next Year?

Nobody can promise you that your doctor will still be in your plan’s network next year — not the plan, not the doctor’s office, and not an agent. Medicare’s own guidance is direct about this: a Medicare Advantage plan can add or remove providers from its network at any time during the year, and your provider can choose to leave the network at any time. What you can do is check properly before you commit to a plan for January, and know what your rights are if the answer changes later.

First, two questions people mix up

These sound alike and are not the same thing.

“Does my doctor take Medicare?” This is about Original Medicare. Most doctors accept assignment, meaning they take the Medicare-approved amount as payment in full and can only bill you the deductible and coinsurance. Some are “non-participating” — they can charge more than the approved amount, though in many cases no more than 15% above it, which Medicare calls the limiting charge. A small number “opt out” of Medicare entirely, for a minimum of two years at a time; Medicare won’t pay for their services except in emergencies.

“Is my doctor in my plan’s network?” This is about Medicare Advantage. Your plan has contracted with a specific list of doctors, hospitals, and facilities. A doctor can accept Medicare, see Original Medicare patients all day long, and still not be contracted with the particular Medicare Advantage plan you’re looking at.

A doctor’s office saying “yes, we take Medicare” answers the first question. If you’re shopping a Medicare Advantage plan, you asked the wrong one.

Networks are not locked for the year

This is the part that catches people. The plan year is fixed — your premium, your copays, your drug tiers hold from January 1 through December 31. The network isn’t. Providers leave mid-year, and plans drop them mid-year, for ordinary contract reasons: the two sides can’t agree on payment rates, a group gets acquired, a physician retires.

Medicare’s position is that even though a plan can change its network at any time, it must protect you from interruptions in medical care and make sure you still have access to medically necessary covered benefits. If you believe a network change will interrupt your care and put your health at risk, Medicare’s instruction is to call 1-800-MEDICARE (1-800-633-4227); TTY users can call 1-877-486-2048.

What notice you’re supposed to get

Federal regulation sets specific advance-notice requirements when a plan terminates a provider contract, and the timing depends on the kind of provider.

Read that second row again, because it’s where people get blindsided. If you see a specialist once a year — a cardiologist you check in with each spring — and your last visit was five months ago, you fall outside the definition of a patient seen on a regular basis. The plan can drop that specialist and you may never receive a letter. You find out when you call for an appointment.

Which is why Medicare’s practical advice is blunt: check with your provider when you schedule an appointment to confirm they’re still in your plan’s network. Every time. Not once a year.

What “in-network” even means depends on the plan type

Before you check a doctor, know what a “no” would cost you.

• HMO. You generally must use network providers. Care outside the network isn’t covered except for emergency care, out-of-area urgent care, or temporary out-of-area dialysis. An HMO with a point-of-service option may let you go out of network for certain services, usually at higher cost.
• PPO. You can use out-of-network doctors and hospitals, but you’ll usually pay more.
• PFFS. If the plan has a network, you can see network providers who agree to treat you, and out-of-network providers who accept the plan’s terms, possibly at higher cost. If the plan has no network, you can see any Medicare-approved provider who accepts the plan’s payment terms and agrees to treat you — and not all will.
• SNP. Some require network providers except for emergency care, out-of-area urgent care, or out-of-area dialysis. Others cover out-of-network care at higher cost. Check the specific plan.

In some plans, choosing a primary care doctor also chooses the hospitals and specialty networks connected to that doctor. So “is my doctor in?” can quietly decide where you’d have surgery.

How to check, properly

During Open Enrollment — October 15 through December 7 — do this for every plan you’re seriously considering:

1. Get the provider directory for next year. It’s on the plan’s website, or you can contact the plan and ask for one. Make sure you’re looking at the coming year’s directory, not the current one.
2. Call the doctor’s office and name the exact plan. Not the insurance company — the specific plan name. Carriers often offer several plans in one county, and a practice may be contracted with some and not others. Ask whether they’re contracted with that plan for next year, since contracts renew on their own schedule.
3. Ask whether they’re accepting new patients under that plan. In-network and taking new patients are two different answers.
4. Check the hospital, and the rest of the cast. Labs, imaging centers, surgical centers, the specialty group your doctor refers to. People verify the primary care doctor and skip everything downstream.
5. Ask the plan what out-of-network care costs, and what happens if you need a covered treatment no network provider offers.

One note on directories. For plan years beginning on or after January 1, 2026, Medicare Advantage organizations must make their provider information available to CMS for publication online, update it within 30 days of learning of a change, and attest at least annually that it’s accurate. That’s a real improvement, and still not a substitute for calling the office — a directory reflects what the plan knew when it last updated.

If you have End-Stage Renal Disease

You can join a Medicare Advantage plan with ESRD. Because most plans restrict you to network providers, Medicare’s advice is to check before you join or switch that the providers you use now — your dialysis facility, your kidney doctor — and the ones you might need later, like a transplant specialist, are in that plan’s network.

If your doctor leaves after January 1

You are not necessarily stuck until next fall.

The Medicare Advantage Open Enrollment Period runs January 1 through March 31 for anyone already in a Medicare Advantage plan. You can switch to a different Medicare Advantage plan, or drop it and return to Original Medicare — and if you do, you can join a standalone Medicare drug plan. You get one change, effective the first day of the month after the plan gets your request.

A case-by-case Special Enrollment Period may apply. Medicare lists being notified of a significant change in your plan’s provider network among the exceptional circumstances that can qualify you for an SEP. These are evaluated individually — it isn’t automatic, and one doctor leaving is not the same as a significant network change. If it applies, you’d have two months to switch. Call 1-800-MEDICARE and describe what happened.

What people get wrong

Asking “do you take Medicare Advantage?” Almost every office takes some Medicare Advantage plan. Name yours.

Trusting a directory over a phone call. Build your list from the directory, then confirm by phone.

Checking in January and never again. Networks move all year. Confirm when you schedule.

Assuming a letter will come. For most specialties, notice only goes to patients seen within the past three months.

Only checking the doctor. The hospital your plan contracts with may matter more in a bad year than the primary care copay does.

Where to get help

Medicare’s Care Compare tool at Medicare.gov/care-compare shows whether doctors accept assignment or participate in Medicare. The Plan Finder at Medicare.gov/plan-compare lists the plans available in your ZIP code once next year’s data posts. Your State Health Insurance Assistance Program (SHIP) gives free, unbiased counseling and can sit with you while you work through a directory. And 1-800-MEDICARE (1-800-633-4227) is available 24 hours a day, 7 days a week.

The honest answer to “will my doctor still take my plan next year” is that you’ll know when you check, and you’ll need to check again — once each fall, and once more whenever you book an appointment.
