Medicare Advantage Charged You Past the Out-of-Pocket Max

What This Means

Your Explanation of Benefits or a provider bill shows a copay, coinsurance, or other cost-sharing amount — but you have already reached your Medicare Advantage plan’s annual out-of-pocket maximum (sometimes called the MOOP). Once you hit that limit, your plan is required to pay 100% of covered services for the rest of the calendar year. You should not owe anything more.

If you are being billed after reaching your maximum, the charge is almost certainly an error. This can happen because of a lag in claims processing, a billing system that has not caught up with your spending totals, or a simple mistake by the plan or provider. Either way, you should not have to pay it.

This protection applies only to Medicare Advantage plans. Original Medicare (Parts A and B) does not have an out-of-pocket maximum, so if you are enrolled in Original Medicare without a Medicare Advantage plan, this page does not apply to your situation.

Why This Happens

• Claims processing delay. Your plan may not have finished processing earlier claims when the new bill was generated. Once those older claims post, your out-of-pocket total will update and the charge should be removed.
• Provider billing system is out of sync. Your doctor’s office or hospital may not know you have hit your maximum. They bill based on the cost-sharing rules in your plan, and it takes time for the plan to inform them.
• The plan made a tracking error. Sometimes a plan miscalculates your running out-of-pocket total — for example, by failing to count a copay you already paid earlier in the year.
• The service may not count toward the maximum. Certain costs — like monthly premiums, out-of-network care in some plans, or non-covered services — do not count toward the out-of-pocket maximum. If the plan classified the service in one of these categories, it may have applied cost-sharing even though you believe you have hit the limit.
• You may be close but not quite there. It is worth double-checking your exact out-of-pocket total with the plan. Sometimes a claim you expected to push you past the maximum was reduced, denied, or has not yet been processed.

Should You Appeal?

What To Do Next

1. Confirm your out-of-pocket total. Call the member services number on your Medicare Advantage plan card and ask for your year-to-date out-of-pocket spending. You can also log into your plan’s website or review your most recent Explanation of Benefits. Write down the exact number they give you and the date you called.
2. Compare the total to your plan’s maximum. Look up your plan’s annual out-of-pocket maximum in your Summary of Benefits or Evidence of Coverage document. In 2025, the in-network ceiling is $9,350 and the combined in-network and out-of-network ceiling can be up to $14,000. Your plan’s limit may be lower.
3. Call your plan and request a correction. If your spending is at or above the maximum, call member services and tell them you were billed cost-sharing after reaching the out-of-pocket limit. Ask them to reprocess the claim with zero cost-sharing and issue a refund if you already paid. Get a reference number for the call.
4. If you already paid the bill, request a refund. If you paid the provider directly, you may need to ask the plan to reprocess the claim first. Once the plan confirms your cost-sharing should be zero, the provider should refund the overpayment. Keep receipts and records of what you paid.
5. File a formal appeal if the plan does not correct it. If member services does not resolve the issue, file a written appeal within 60 days of the date on your Explanation of Benefits. Include a copy of the EOB, your out-of-pocket spending summary, and a simple letter stating you have reached the annual maximum and should not owe cost-sharing.
6. Contact your State Health Insurance Assistance Program (SHIP). If you need help navigating the process, a SHIP counselor can review your documents, help you understand your plan’s rules, and assist with an appeal — all for free.
