Will My Doctor or Hospital Accept My Medicare Supplement Plan?
Medicare Supplement plans generally do not use provider networks. If a doctor or hospital accepts Original Medicare and agrees to treat you, your Medicare Supplement coverage can ordinarily be used there.
If you’re asking, “Will my doctor accept my Medicare Supplement plan?” the answer usually depends on whether the doctor accepts Original Medicare—not which insurance company issued your Medicare Supplement policy.
Medicare Supplement insurance, also called Medigap, generally does not use provider networks. If a doctor or hospital accepts Original Medicare and agrees to treat you, Medicare processes the claim first. Your Medicare Supplement plan then pays according to the standardized benefits included in your policy.
In most cases, you do not need to ask whether a provider accepts your specific Medicare Supplement company. Instead, ask:
“Does this doctor or hospital accept Original Medicare?”
There are important differences between providers who accept Medicare assignment, non-participating providers and providers who have formally opted out of Medicare. I’ll explain those distinctions below, along with what they can mean for your Medicare Supplement coverage.

Do Medicare Supplement Plans Have Provider Networks?
Standard Medicare Supplement plans generally do not have provider networks.
Medicare Supplement insurance works alongside Original Medicare. When you receive a Medicare-covered service, Medicare processes the claim first. Your Medicare Supplement insurance company then receives the claim and pays according to the standardized benefits of your plan.
Your doctor ordinarily does not need a separate contract with your Medicare Supplement insurance company.
If a provider tells you that the office does not participate with your particular Medigap company, ask whether the provider accepts Original Medicare. Some offices mistakenly look for a Medicare Supplement insurance company in their network system even though Medigap coverage does not work like a traditional network-based health plan.
What Does “Accepts Medicare” Mean?
The phrase “accepts Medicare” can describe several different arrangements. Understanding the difference helps prevent unnecessary confusion.
Participating Medicare Providers
A participating provider has agreed to accept Medicare assignment for Medicare-covered services.
Accepting assignment means the provider agrees to accept the Medicare-approved amount as full payment for the covered service. Medicare pays its portion, and you or your Medicare Supplement policy are responsible for the applicable deductible or coinsurance.
Participating providers cannot charge more than the Medicare-approved amount for a Medicare-covered service.
Non-Participating Medicare Providers
A non-participating provider has not agreed to accept Medicare assignment for every Medicare-covered service. However, that provider can still treat Medicare beneficiaries and submit claims to Medicare.
A non-participating provider may choose to accept assignment for an individual service. When the provider does not accept assignment, you may have to pay the bill upfront and wait for Medicare and your Medicare Supplement plan to process the claim.
In many cases, a non-participating provider may charge up to 15% above Medicare’s approved amount. The additional amount is called a Medicare Part B excess charge.
The rules can vary by state. Pennsylvania prohibits healthcare providers from charging Medicare Part B excess charges. Plan G covers legally permitted Part B excess charges, while Plan N does not.
A non-participating provider is not the same as a provider who has opted out of Medicare.
Providers Who Have Opted Out of Medicare
Certain doctors and other healthcare professionals can formally opt out of Medicare.
When a provider has opted out, Medicare generally will not pay for services received from that provider, except for qualifying emergency or urgent care. A Medicare Supplement plan ordinarily will not pay for a service when Medicare does not approve and process the claim.
If you choose to use an opted-out provider, you may be asked to enter into a private contract agreeing to pay for the care yourself.
This is an important exception to the general rule that Medicare Supplement coverage can be used anywhere Original Medicare is accepted.
Will a Hospital Accept My Medicare Supplement Plan?
If a hospital participates in Original Medicare, it can generally bill Medicare and your Medicare Supplement plan for Medicare-covered services.
As with doctors, you ordinarily do not need the hospital to belong to a separate Medicare Supplement network.
Before receiving non-emergency care, confirm:
-
The hospital participates in Original Medicare
-
Your doctor participates in or accepts Medicare
-
Any other providers involved in your care accept Medicare
-
The service is covered by Medicare
-
Any required medical necessity rules are satisfied
A hospital may participate in Medicare while a particular physician, anesthesiologist or other professional involved in your treatment has a different Medicare status. Checking the individual providers can help you avoid surprises.
Does the Medicare Supplement Company Matter to My Doctor?
Your choice of Medicare Supplement insurance company generally does not determine which Medicare-participating doctors you can use.
Medicare Supplement benefits are standardized by plan letter in most states. A Plan G from one insurance company provides the same standardized medical benefits as a Plan G from another company.
The differences between insurance companies can include:
-
Monthly premiums
-
Household discounts
-
Rate history
-
Financial strength
-
Customer service
-
Underwriting requirements
-
Application or policy fees
Paying a higher premium to one Medicare Supplement company does not ordinarily provide access to a larger doctor or hospital network.
Can a Doctor Refuse to Accept New Medicare Patients?
Yes. A doctor may participate in Medicare but still decide not to accept new patients.
Medicare participation does not require a physician to accept every person with Medicare. A practice may limit new patients because of staffing, scheduling, specialty requirements or other business considerations.
That is different from refusing your particular Medicare Supplement plan.
When contacting a new provider, ask:
- Are you accepting new patients with Original Medicare?
- Does the doctor accept Medicare assignment?
- Has the doctor opted out of Medicare?
- Will the office submit claims to Medicare?
- Is the service I need covered by Medicare?
You can also use Medicare’s online Care Compare directory, but confirming directly with the provider’s office before your appointment is still a good idea.
What If the Office Says It Does Not Accept My Medigap Company?
First, confirm that the office understands you have Original Medicare with a Medicare Supplement policy—not a Medicare Advantage plan.
You can say:
“I have Original Medicare as my primary coverage. My Medicare Supplement policy is secondary. Does the doctor accept Original Medicare?”
If the office accepts Original Medicare but remains uncertain about your Medigap company, ask the billing department to verify how Medicare crossover claims are handled.
Do not assume you must change Medicare Supplement companies simply because a receptionist cannot find the company in a provider-network directory. Standard Medigap policies do not generally use those networks.
Medicare Supplement vs Medicare Advantage Provider Rules
Medicare Supplement and Medicare Advantage coverage operate differently.
With Original Medicare and a Medicare Supplement plan, you can generally use any doctor or hospital in the United States that takes Medicare and accepts you as a patient.
Medicare Advantage plans may use provider networks and service areas. Depending on the plan, receiving non-emergency care outside the network may cost more or may not be covered.
This provider flexibility is one reason some people prefer Original Medicare with Medicare Supplement coverage.
Can I Use My Medicare Supplement Plan in Another State?
Yes. Standard Medicare Supplement coverage is not ordinarily limited to the state where you purchased the policy.
If you travel or move within the United States, you can generally use any doctor or hospital that participates in Medicare and accepts you as a patient.
Your policy’s premium may change after a permanent move, depending on the insurance company’s rating rules and your new address. However, your standardized Medigap benefits do not turn into a restricted local network when you cross state lines.
Original Medicare provides only limited coverage outside the United States. Certain Medicare Supplement plans include a limited foreign-travel emergency benefit subject to the standardized policy requirements.
What Medicare Supplement Plans Do Not Cover
A Medicare Supplement plan helps pay certain deductibles, coinsurance and copayments left by Original Medicare. It does not transform a non-covered service into a Medicare-covered service.
If Medicare does not cover a service, your Medicare Supplement plan ordinarily will not cover it merely because you have supplemental insurance.
Examples of services generally not covered by Original Medicare include:
-
Routine dental care
-
Most routine vision care
-
Hearing aids
-
Long-term custodial care
-
Cosmetic surgery
-
Routine physical examinations
-
Concierge or membership fees
-
Most care received outside the United States
Always confirm whether Medicare covers the service as well as whether the provider accepts Medicare.
Frequently Asked Questions
Can I use any doctor with Medicare Supplement insurance?
You can generally use any doctor in the United States who takes Original Medicare and accepts you as a patient. Standard Medicare Supplement plans ordinarily do not restrict you to an insurance-company provider network.
Does my doctor have to accept my specific Medigap company?
Generally, no. The doctor bills Original Medicare first. The Medicare Supplement company then pays according to your policy’s standardized benefits.
Is a non-participating provider the same as an opted-out provider?
No. A non-participating provider can still treat Medicare beneficiaries and submit Medicare claims. An opted-out provider generally does not bill Medicare and may require a private contract.
Will my Medicare Supplement plan pay if the doctor has opted out of Medicare?
Generally, no. If Medicare does not approve and process the claim, the Medicare Supplement policy ordinarily has no Medicare cost-sharing amount to supplement.
Can a doctor stop accepting Medicare?
A provider can change Medicare participation status or stop accepting new Medicare patients. Confirm the provider’s current status before scheduling non-emergency care.
Will hospitals accept Medicare Supplement Plan G or Plan N?
A Medicare-participating hospital can generally bill Original Medicare and your Medicare Supplement plan. Plan G and Plan N do not ordinarily use separate hospital networks.
Can I keep my doctors if I change Medicare Supplement companies?
Usually, yes. Changing from one standard Medicare Supplement company to another does not ordinarily change which Medicare-participating doctors you can use.
