My doctor left my Medicare plan's network: can I switch?

Published by MedicareQuotesForYou. Published July 30, 2026. Last reviewed July 30, 2026.

Short answer

A provider leaving your plan's network part-way through the year does not, on its own, give you a Special Enrollment Period. That is the honest answer, and it is not the one most pages give you. Medicare does not treat a network change as a qualifying event, so in most cases you cannot simply switch plans the week you get the letter.

But you almost certainly have more options than the letter suggests. Depending on your circumstances you may be able to keep seeing that doctor at in-network cost for a period if you are in active treatment, request an out-of-network authorisation, use your plan's out-of-network benefit if it is a PPO, move to a 5-star plan if one operates where you live, or make a change in the January 1 to March 31 Medicare Advantage Open Enrollment Period.

And if the plan's directory was wrong when you enrolled — it listed the doctor as in-network and that was not accurate — that is a different matter. Call 1-800-MEDICARE and ask for a Special Enrollment Period on the basis of incorrect plan information. It is decided case by case, but it is a recognised ground and it is worth asking.

Every route open to you, and when

Options after a mid-year network change. Which apply depends on your plan type, your health situation and where you live.
Route	When it is available	What it gets you
Continuity of care	If you are in an active course of treatment when the provider leaves.	Plans are generally required to allow a period of continued care with the departing provider so treatment is not interrupted. Ask the plan in writing, and reference the treatment you are in the middle of.
Out-of-network authorisation	Any time. Strongest where no in-network provider has the same expertise or can see you within a reasonable time or distance.	The plan agrees to cover care from the departed provider, sometimes at in-network cost sharing. Put the request in writing and keep the response.
Your plan's out-of-network benefit	If you are in a PPO. HMOs generally cover out-of-network care only in an emergency.	You can keep seeing the doctor, but at a higher cost share. Check whether that cost still counts towards your annual out-of-pocket maximum.
5-star Special Enrollment Period	Once between December 8 and November 30, if a 5-star plan is offered where you live.	A mid-year move to a plan Medicare rates 5 stars. Check whether the doctor is in that plan's network before using it — you only get one.
Medicare Advantage Open Enrollment Period	January 1 to March 31, once, if you are in an Advantage plan.	Switch to another Advantage plan, or drop back to Original Medicare and add a Part D plan. Takes effect the first of the following month.
Annual Enrollment Period	October 15 to December 7 every year.	Change to any plan available in your area, effective January 1. The route most people will end up using.
Special Enrollment Period for incorrect information	If the plan or its directory gave you materially wrong information about the network.	Medicare may grant a one-off window. Decided case by case by 1-800-MEDICARE. Have dates, names and any printouts ready.
Moving out of the service area	If you move, permanently, outside the plan's service area.	A genuine Special Enrollment Period. Not a route to engineer for a network problem, but relevant if a move was already planned.

Before you do anything, find out what actually happened Network departures are often narrower or more temporary than the letter implies. Ask the doctor's office three questions: is the practice out of the plan entirely or only at one location; is this a contract dispute that may be settled before the next plan year; and will they be in that plan's network next year. A meaningful share of these disputes are resolved, and a practice that has left one plan for next year is usually in several others.

The trap in switching back to Original Medicare

The reflex, when a network fails you, is to leave networks behind altogether and return to Original Medicare, where any provider who accepts Medicare will see you. That instinct is sound. The complication is the supplement.

Original Medicare on its own has no annual limit on what you pay. Most people who return to it buy a Medigap policy to cover that exposure — and outside a guaranteed-issue window, insurers in most states may review your medical history and decline you or charge more. A network change is not one of the situations that creates a guaranteed-issue right. So you can generally leave the Advantage plan in the January to March window, but there is no guarantee you can buy the supplement you would want alongside it.

Two exceptions are worth knowing:

The trial right. If you joined a Medicare Advantage plan when you first became eligible at 65, you generally have 12 months to change your mind, drop the plan and buy a Medigap policy with guaranteed-issue rights. If you are inside your first year, this changes the whole picture.
State rules. A few states give broader or ongoing Medigap rights than the federal minimum. Whether you live in one of them can decide this question, so check before assuming underwriting applies to you.

The practical order is: find out whether you can get the Medigap policy before you drop the Advantage plan, not after. See how to switch back to Original Medicare for the sequence.

What to do this week

Call the doctor's office. Confirm the scope and the date, and ask whether they expect to be in that plan's network next year.
If you are mid-treatment, call the plan and use the words "continuity of care". Follow the call with a written request. Note the reference number and who you spoke to.
Ask the plan directly what it will authorise. Whether it will cover the provider out of network, at what cost share, and for how long. Get it in writing.
Check whether a 5-star plan operates in your county, and if one does, whether your doctor is in it. That is the only mid-year switch available to most people outside January to March.
If the directory was wrong when you enrolled, call 1-800-MEDICARE and ask about a Special Enrollment Period based on incorrect information.
If none of that works, plan the change rather than rush it. Use the January to March window or the autumn Annual Enrollment Period, and choose the plan by checking your doctors and prescriptions first, benefits second.

Frequently asked questions

Can I change Medicare plans mid-year because my doctor left the network?

Generally no. Medicare does not treat a provider leaving a plan's network as an event that creates a Special Enrollment Period. The usual routes are the Medicare Advantage Open Enrollment Period from January 1 to March 31, the Annual Enrollment Period from October 15 to December 7, or the 5-star plan window if a 5-star plan is offered where you live.

Does my plan have to tell me before my doctor leaves the network?

Plans are generally required to make a good-faith effort to notify enrollees who use a provider in advance of that provider leaving the network, and to allow for continuity of care where someone is in the middle of treatment. In practice, notice quality varies. If you found out from the practice rather than the plan, say so when you call — it is relevant.

Can I keep seeing a doctor who has left my Medicare Advantage network?

Sometimes. If you are in an active course of treatment, the plan may be required to allow continued care for a period. If your plan is a PPO, out-of-network care is covered at a higher cost share. In an HMO, out-of-network care is generally covered only in an emergency, unless the plan grants an authorisation. Ask for an authorisation in writing before the appointment, not after.

What if the plan's provider directory was wrong when I signed up?

That is a stronger position. If the plan listed a doctor as in-network and that was not accurate, call 1-800-MEDICARE and ask for a Special Enrollment Period on the basis of incorrect information from the plan. It is assessed individually, so have dates, the name of the provider, and any printout or screenshot of the directory entry to hand.

If I go back to Original Medicare can I keep my doctor?

If the doctor accepts Medicare, yes. Original Medicare has no network, so any provider who accepts Medicare assignment can see you, anywhere in the country, without referrals. The question to settle before you move is not the doctor but the supplement: Original Medicare has no cap on your annual costs, and a Medigap policy may involve medical underwriting depending on your state and your timing.

Should I switch plans or wait until the Annual Enrollment Period?

If you are not in active treatment and your doctor may be back in the network next year, waiting for the autumn Annual Enrollment Period usually gives you the best information and the widest choice. If you are mid-treatment, or the departure leaves you without a specialist you need, use the January to March window or press the plan for an authorisation rather than waiting.
