Yes, you can choose to pay out of pocket for medical care instead of using Medicare, but the decision has real consequences you need to understand first.
Medicare covers most of your hospital and doctor visits once you are enrolled, but you are not forced to use it for every service. You can decline Medicare coverage for a specific visit, a particular provider, or even all services — and pay the bill yourself. However, this choice works differently depending on whether you have Original Medicare (Parts A and B) or a Medicare Advantage plan, and opting out of Medicare entirely is a separate decision with penalties that can follow you for years.
The most common reason people choose to self-pay is to see a provider who does not accept Medicare, or to avoid Medicare's rules about which treatments it will cover. But before you decide to pay out of pocket, you need to know what it actually costs, whether you can get that money back later, and what happens to your coverage if you refuse Medicare for an extended period.
Key Takeaways
- You can decline Medicare for a single visit or service and pay the provider directly, but the provider must tell you in advance that Medicare will not cover it.
- Providers who do not accept Medicare at all must give you a signed form before treatment explaining that you will pay the full bill yourself.
- Refusing Medicare coverage for all services (called "opting out") triggers a two-year waiting period before you can re-enroll, and you may face late-enrollment penalties when you do.
- Medicare Advantage plans have different rules — you cannot straightforward opt out of your plan for one visit, and switching plans outside the annual enrollment period is limited.
- If a provider bills Medicare without your permission, you have the right to request a refund, but you must act quickly.
Declining Medicare for a Single Service or Visit
If you want to see a doctor or get a procedure that Medicare covers, but you prefer to pay out of pocket, you can do this — but only if the provider agrees and follows Medicare's rules about advance notice. The provider must give you a written notice before treatment that explains Medicare would normally cover the service, that you are choosing not to use Medicare, and that you will be responsible for the full cost. This form is called an Advance Beneficiary Notice (ABN), and you must sign it before the visit.
The ABN protects you by making sure you know the price before you commit. It also protects the provider by documenting that you made an informed choice. Without a signed ABN, the provider cannot legally bill you for a service Medicare covers — they must bill Medicare instead, and you pay only your normal copay or coinsurance.
This option works best for one-time situations: a test your doctor thinks Medicare might deny, a second opinion from a specialist, or a treatment you want to try before Medicare approves it. If you plan to self-pay regularly with the same provider, that is a different conversation, and you may want to ask whether the provider offers a discount for self-pay patients.
Seeing Providers Who Do Not Accept Medicare
Some doctors, dentists, mental health counselors, and other providers do not accept Medicare at all. These are called non-participating providers. If you choose to see one, you will pay their full fee out of pocket, and Medicare will not reimburse you — even if the service is normally covered.
Before you see a non-participating provider, ask them directly whether they accept Medicare. If they do not, ask for their fees in writing and whether they offer a discount for self-pay. Some non-participating providers charge less than Medicare-participating providers because they do not have to follow Medicare's billing rules or wait for Medicare's payment. Others charge more because they cater to patients with private insurance or cash.
Non-participating providers must still give you a written notice before treatment if they do not accept Medicare. This protects you the same way an ABN does — you know the cost before you proceed. If a non-participating provider treats you without this notice and then bills you, you have the right to dispute the bill.
Opting Out of Medicare Entirely: What Happens
Opting out of Medicare is different from declining a single service. When you opt out, you are telling Medicare you do not want coverage for a set period — usually two years. During that time, you cannot use Medicare for any service, and Medicare will not pay for anything, even emergencies. You must pay the full cost of all medical care yourself.
If you opt out, you must sign a form called an Opt-Out Agreement with Medicare directly (not with your doctor). This agreement lasts two years from the date you sign it. After two years, you can re-enroll in Medicare, but you may face late-enrollment penalties — a permanent increase to your Part B and Part D premiums — unless you have a may have access to reason for the gap.
Opting out makes sense only in rare situations: if you are still working and covered by your employer's health plan, or if you are moving out of the United States for two years. For most people, the cost of self-paying for all medical care, plus the penalties when you re-enroll, makes opting out much more expensive than staying in Medicare.
Medicare Advantage Plans and Self-Pay Choices
If you have a Medicare Advantage plan (Part C), your choices are more limited. Medicare Advantage plans are run by private insurance companies, and they set their own rules about which providers you can see and which services are covered. You cannot straightforward decline your plan for one visit the way you can with Original Medicare.
If you want to see a provider outside your plan's network, you have two options: pay out of pocket for the full cost, or wait until the annual enrollment period (October 15 to December 7 each year) and switch to a different plan. Some Medicare Advantage plans do cover out-of-network care, but usually at a higher cost to you. Check your plan's documents or call the plan to find out.
If you want to switch to Original Medicare instead, you can do this during the annual enrollment period, or if you have a may have access to life event (like moving out of your plan's service area). Once you switch, you are out of your Medicare Advantage plan and back in Original Medicare, and you cannot switch back until the next enrollment period.
What Happens If a Provider Bills Medicare Without Your Permission
Sometimes a provider bills Medicare even though you asked them to self-pay, or they bill you for a service Medicare covers without giving you an ABN first. If this happens, you have the right to dispute the bill and request a refund.
If Medicare paid the provider, contact Medicare and explain that you did not authorize the service or that the provider did not give you proper notice. Medicare will investigate, and if they find the provider billed incorrectly, they will recover the payment from the provider. You should not have to pay anything.
If the provider billed you directly (without going through Medicare), you can dispute the bill with the provider and ask for an itemized statement. If the provider cannot show that you signed an ABN or agreed in advance to self-pay, you may be able to have the bill reduced or removed. Keep copies of all notices and agreements you sign.
The Real Cost of Self-Paying for Medicare Services
Before you choose to self-pay, understand what it costs. Medicare-participating providers have agreed to charge a set amount for each service — called the Medicare-approved amount. If you self-pay, the provider can charge you more than this amount, and you will pay the difference.
For example, if Medicare's approved amount for a doctor visit is $150, but the provider charges $200 for self-pay patients, you pay the full $200. If you had used Medicare, you would pay only your copay (usually $20 to $50) and Medicare would pay the rest. Self-paying can cost you hundreds or thousands of dollars more, depending on the service.
Before you self-pay, ask the provider for their self-pay fee in writing. Compare it to what you would pay with Medicare (your copay plus any coinsurance). Also ask whether the provider offers a discount for self-pay patients — some do, especially if you pay upfront. Get everything in writing so there are no surprises when you receive the bill.
Frequently Asked Questions
Can I use Medicare for some services and self-pay for others with the same doctor?
Yes. For each service, your doctor must give you an ABN if they think Medicare might not cover it or if you are choosing to self-pay. You can use Medicare for one visit and self-pay for another visit with the same provider, as long as the proper notices are in place each time.
If I self-pay now, can I ask Medicare to reimburse me later?
No. Once you self-pay, that is your responsibility. Medicare will not reimburse you after the fact, even if the service was normally covered. This is why it is important to understand the cost before you agree to self-pay.
What if I cannot afford the self-pay bill after I receive it?
Contact the provider's billing office and ask about payment plans or financial hardship programs. Many providers will work with you to set up a payment schedule. You can also ask whether the provider will accept a lower amount if you pay in full upfront. Do not ignore the bill — unpaid medical bills can damage your credit and lead to collection action.
Does opting out of Medicare affect my Social Security benefits?
No. Opting out of Medicare does not change your Social Security payments. However, if you opt out and then re-enroll later, you may face late-enrollment penalties on your Medicare premiums, which will be deducted from your Social Security check.
Can I opt out of just Part B (doctor visits) and keep Part A (hospital)?
This is complicated and depends on your situation. If you are still working and covered by your employer's health plan, you may be able to delay Part B without penalties. Talk to Medicare directly before you make any changes — the rules are strict, and a mistake can cost you thousands in penalties.
