What happens when your Medicare provider number is suspended or terminated

When Medicare suspends or terminates your provider number, you stop receiving Medicare payments when ready. The Centers for Medicare & Medicaid Services (CMS) can suspend your number for reasons ranging from billing errors and compliance violations to criminal convictions or exclusion from federal programs. A suspension is typically temporary — lasting 30 days to several months — while a termination is permanent unless you go through a formal reinstatement process.

The difference matters because reinstatement requires you to demonstrate that the underlying problem has been corrected. You cannot straightforward wait out the clock. CMS will not automatically restore your number when a suspension period ends if the reason for the action remains unresolved.

Your first step is to understand exactly why your number was suspended or terminated. CMS sends a formal notice to your billing address and to any authorized official listed on your Medicare enrollment record. That notice includes the specific reason, the effective date, and instructions for appeal or reinstatement. If you did not receive the notice, contact your Medicare Administrative Contractor (MAC) — the regional contractor that processes Medicare claims in your state — and request a copy.

Key Takeaways

  • Your Medicare provider number suspension or termination notice from CMS explains the reason and lists the MAC contact for your region.
  • Reinstatement requires you to correct the underlying problem — whether that is unpaid overpayments, compliance training, or removal from an exclusion list — not straightforward to wait out a suspension period.
  • You can request reconsideration or appeal the suspension or termination through your MAC, or you can request reinstatement once the problem is resolved.
  • The reinstatement process typically takes 30 to 60 days after CMS receives your request and supporting documentation.
  • If you are excluded from federal programs by the Office of Inspector General (OIG), you must be removed from that list before Medicare will reinstate your provider number.

Determine whether you need reconsideration, appeal, or reinstatement

Three different paths exist, and which one applies depends on whether you believe the suspension or termination was wrong, or whether you accept the reason but have now fixed the problem.

Reconsideration is the first step if you believe CMS made an error in suspending or terminating your number. You have 30 days from the date on the notice to request reconsideration through your MAC. You must explain in writing why the suspension or termination was incorrect and provide supporting documentation. This path does not require you to fix anything — it argues that nothing was broken.

Appeal is the formal process if you disagree with the reconsideration decision. Appeals go through an independent review process and can take several months. You can appeal to your MAC's medical review contractor, and if you disagree with that decision, you can appeal further to an Administrative Law Judge.

Reinstatement is the path if you accept that the reason for suspension or termination was valid but you have now corrected it. You do not need to wait for a suspension period to end. You can request reinstatement as soon as the underlying issue is resolved.

Common reasons for suspension and what you must do to reinstate

The reason for your suspension or termination determines what documentation CMS will require before reinstating your number.

Unpaid overpayments: If Medicare determined you were overpaid and you did not repay the amount, CMS suspends your number until the debt is settled. To reinstate, you must pay the full overpayment amount or set up a payment plan with your MAC. You will need a letter from your MAC confirming the payment or plan is in place before submitting a reinstatement request.

Billing or compliance violations: If you submitted claims that violated Medicare billing rules — such as billing for services not rendered, billing at incorrect rates, or failing to obtain required documentation — CMS may suspend your number pending corrective action. Reinstatement requires you to complete compliance training (often through the Medicare Learning Network), submit a corrective action plan, and provide evidence that you have implemented new billing procedures. Your MAC will specify which training or documentation is required.

Exclusion by the Office of Inspector General (OIG): If you or your practice were excluded from federal healthcare programs by the OIG, your Medicare provider number cannot be reinstated until you are removed from the exclusion list. Exclusions result from criminal convictions, civil fraud judgments, or licensing board actions. Removal requires either waiting out the exclusion period (which varies) or, in some cases, requesting a waiver. Check the OIG Exclusions List at oig.hhs.gov to confirm your status.

Failure to meet enrollment requirements: If you did not respond to a Medicare re-enrollment notice, did not renew your enrollment, or did not provide required documentation, CMS may terminate your number. Reinstatement requires you to submit a new or updated Medicare enrollment process (Form CMS-855 for individual providers or the appropriate form for your provider type) with all required supporting documents.

Steps to request reinstatement through your Medicare Administrative Contractor

Once you have corrected the underlying problem, contact your MAC to request reinstatement. Your MAC is the regional contractor that processes Medicare claims in your state. You can find your MAC at cms.gov/mac by entering your state and provider type.

Send a written request to your MAC that includes: your full name and Medicare provider number, the date your number was suspended or terminated, a clear statement that you are requesting reinstatement, a description of the problem that led to the suspension or termination, and documentation showing that the problem has been corrected. For unpaid overpayments, include a payment receipt or payment plan letter. For compliance violations, include certificates of training completion and a written corrective action plan. For exclusions, include a letter from the OIG confirming removal from the exclusion list or a copy of the removal notice.

Send your request by mail or email to the address or email listed on your MAC's website. Keep a copy for your records and note the date you sent it. Your MAC will acknowledge receipt and provide you with a case number. Processing typically takes 30 to 60 days. During this time, you cannot bill Medicare, so do not submit claims under your suspended or terminated number.

If your MAC does not respond within 60 days, follow up with a phone call to the number listed on your MAC's website. Ask for the status of your reinstatement request by case number.

What to do if you are excluded from federal programs

If your suspension or termination is tied to an OIG exclusion, reinstatement of your Medicare provider number depends on removal from the exclusion list. You cannot reinstate your Medicare number while you remain excluded.

Check your status on the OIG Exclusions List at oig.hhs.gov/exclusions. Search by your name or provider number. The list shows the reason for exclusion and the exclusion period. Some exclusions are permanent; others have an end date. If your exclusion has an end date and that date has passed, you can request removal by contacting the OIG directly. If your exclusion is permanent or the end date has not arrived, you may be able to request a waiver, though waivers are granted only in limited circumstances and require a detailed written justification.

Once you are removed from the OIG Exclusions List, send a copy of the removal notice to your MAC along with your reinstatement request. Your MAC will then process your reinstatement.

Billing and payments while your provider number is suspended

Do not submit claims to Medicare under a suspended or terminated provider number. Claims submitted during a suspension will be denied. If you have staff or billing contractors, notify them when ready that your number is suspended and that no claims should be submitted until reinstatement is complete.

If you submitted claims before learning of the suspension, those claims may be denied. Contact your MAC to ask whether denied claims can be resubmitted after your number is reinstated. Some MACs will allow resubmission; others will not. The answer depends on the reason for suspension and the timing of the claims.

Patients should not be billed for services that were denied because of your suspended provider number. If you billed patients directly for denied claims, you may need to refund those amounts. Check your Medicare enrollment agreement and your state's billing laws for specific requirements.

Appealing a suspension or termination decision

If you believe your suspension or termination was incorrect, you have the right to appeal. The appeal process is separate from reinstatement and takes longer, but it may result in your number being restored retroactively and compensation for lost billing time.

Request reconsideration from your MAC within 30 days of receiving the suspension or termination notice. Your request must explain why you believe the action was wrong and must include supporting documentation. Your MAC will review your request and issue a reconsideration decision, usually within 30 to 60 days.

If you disagree with the reconsideration decision, you can appeal to an independent review contractor. This appeal must be filed within 30 days of the reconsideration decision. The independent review process typically takes 60 to 90 days. If you disagree with that decision, you can appeal to an Administrative Law Judge, though this process can take six months or longer.

While an appeal is pending, your provider number remains suspended or terminated. You cannot bill Medicare during this time. However, if you ultimately win your appeal, CMS may restore your number retroactively and process claims that were submitted before the suspension.

Frequently Asked Questions

How long does reinstatement usually take?

Most MACs process reinstatement requests within 30 to 60 days of receiving your written request and all required documentation. The timeline depends on how quickly you gather and submit supporting documents and how busy your MAC is. If your MAC does not respond within 60 days, contact them by phone to check the status of your case.

Can I bill patients directly while my Medicare number is suspended?

You cannot bill Medicare, but you may be able to bill patients directly if you follow specific rules. You must notify patients in advance that your Medicare number is suspended and that they will be responsible for payment. Some states and insurance plans have rules about direct billing during a suspension, so check your state's requirements and your malpractice insurance policy before billing patients directly.

What if I disagree with the reason for my suspension?

You can request reconsideration within 30 days of receiving the suspension notice. Explain in writing why you believe the suspension was incorrect and provide supporting documentation. If your MAC denies reconsideration, you can appeal to an independent review contractor and then to an Administrative Law Judge. Appeals take longer than reinstatement requests but may result in retroactive restoration of your number.

Do I need a lawyer to request reinstatement?

You do not need a lawyer to request reinstatement, but the process requires careful documentation and attention to important date. If the reason for suspension is complex — such as a billing audit or compliance investigation — consulting with a healthcare attorney or compliance specialist may help you prepare a stronger reinstatement request and avoid future problems.

What happens to my old claims if my number is reinstated?

Claims submitted under your suspended number will be denied. After reinstatement, you can ask your MAC whether those claims can be resubmitted. Some MACs allow resubmission; others do not. The answer depends on the reason for suspension and how long your number was suspended. Ask your MAC about their resubmission policy when you request reinstatement.
