What do I do if Medicare won't pay?

Editorial team Published on

If Medicare refuses to pay for a medical service, item, or prescription drug, you are responsible for the bill unless you successfully appeal the decision or have secondary insurance.

What Happens When a Claim is Denied

  • Notice of Denial: You will receive a notice explaining why payment was refused. If you have Original Medicare, this arrives on a Medicare Summary Notice (MSN). If you have a Medicare Advantage or Part D plan, your plan will send a denial letter.
  • Advance Notice (ABN): If your doctor or provider expects Medicare to deny coverage before giving you a service, they should have you sign an Advance Beneficiary Notice of Non-coverage (ABN). This lets you choose whether to receive the care and pay out of pocket or request that a claim be submitted anyway so you can appeal.

Steps You Can Take

  • File an Appeal: Every denial notice includes a strict deadline and instructions on how to appeal. Act quickly.
  • Get Doctor Support: Ask your doctor for a letter explaining the strict medical necessity of the treatment or test.
  • Check Secondary Coverage: If you have a Medigap (supplemental) policy, employer insurance, or Medicaid, check if they pick up costs that Original Medicare rejects.
  • Use Official Tools: You can verify coverage rules directly using the official Medicare Coverage Checker.

What does Trump's new bill do to Medicare?

President Donald Trump's recently announced initiative involving Medicare provides a one-time $90 payment to more than 20 million enrollees to help cover their Medicare Part B premiums, while his broader legislative package, the "One Big Beautiful Bill Act," implements spending cuts to Medicare and safety-net programs.

The $90 Medicare Part B Rebate

  • Funding: The White House Fact Sheet states that these $90 direct payments are drawn from the unused $2 billion in the federal Medicare Improvement Fund.
  • Eligibility: Most traditional Medicare Part B enrollees qualify, except for those whose premiums are covered by Medicaid or who pay an Income-Related Monthly Adjustment Amount. Beneficiaries in Medicare Advantage plans generally do not qualify.
  • Distribution: Payments are sent out via direct deposit or mail in early October.

Impact of the "One Big Beautiful Bill Act" (OBBB)

  • Funding Reductions: Signed into law, the legislation includes cuts to overall Medicare spending starting in 2026.
  • Potential Effects: Policy analysts and advocacy groups note that these reductions could lead to higher premiums, fewer plan options, or reduced services for beneficiaries over time.
  • Medicaid and Long-Term Care: The law also cuts funding to Medicaid, which can affect low-income seniors relying on the program for nursing home or long-term care access.

What happens if you can't afford to pay for Medicare?

If you cannot afford to pay for Medicare, you risk losing your coverage for Parts B or D, but you will receive warnings and have access to state and federal assistance programs before that happens.

What Happens If You Stop Paying

  • Grace Period: You receive a grace period (usually two to three months) to pay past-due premiums before your plan cancels your coverage.
  • Loss of Coverage: If you fail to pay after the grace period, you are disenrolled from your plan.
  • Re-enrollment Limits: After disenrollment, you must wait until the next open enrollment period to sign up again.
  • Late Penalties: Going without drug coverage (Part D) for 63 days or more can trigger a permanent monthly late penalty when you rejoin.

Programs That Help Pay Costs

You do not have to lose coverage because low-cost and free options exist to help manage expenses:

  • Medicare Savings Programs (MSPs): State programs that pay your Part A and Part B premiums, deductibles, and coinsurance.
  • Extra Help: A federal program that lowers prescription drug costs under Part D.
  • Medicaid: A joint program that covers medical costs for people with limited income and resources.

Do you ever have to pay Medicare back?

Yes, you must pay Medicare back if they make conditional payments for medical treatment related to an accident, injury, or illness that is ultimately covered by a liability settlement, workers' compensation, or judgment.

Conditional Payments

  • Medicare calls these payments "conditional" because they step in to pay medical bills immediately so you do not have to pay out of pocket.
  • You or your lawyer must repay Medicare out of any final financial settlement, judgment, or award.
  • This obligation is a legal Medicare lien on your recovery funds.

Repayment Process

  • Notification: You or your attorney must report the settlement or claim to the Benefits Coordination & Recovery Center (BCRC).
  • Demand Letter: Medicare issues a final demand letter detailing the exact amount owed after reviewing treatment costs.
  • Deadline: You generally have 60 days from the final demand letter to repay the amount before interest begins to accrue.

Do I legally have to pay for Medicare?

No, you are not legally required to sign up for or pay for Medicare when you turn 65, but choosing not to can result in financial penalties or complications.

Taxes vs. Enrollment

  • Medicare Taxes: While you are working, paying Medicare taxes (part of FICA) through your paycheck is legally mandatory.
  • Medicare Enrollment: Enrolling in Medicare coverage once you turn 65 is voluntary. You can legally decline or delay it.

When You Might Have to Pay or Face Penalties

  • The Catch with Social Security: If you choose to drop or delay Medicare Part A and you are already collecting Social Security benefits, you cannot keep your Social Security benefits without being enrolled in Part A. Enrolling in premium-free Part A is automatic in that case.
  • Late Enrollment Penalties: If you decline Medicare Part B (medical insurance) or Part D (prescription drugs) when you are first eligible and do not have qualifying health coverage from an active employer, you will face permanent late-enrollment penalties added to your monthly costs if you sign up later. Read more about these rules on Is Medicare Mandatory? Delays, Declines, and Penalties.
  • Still Working: If you are still working at 65 and have health insurance through your job, you can often delay signing up for Part B without facing a penalty. Learn more about working past 65 with guidance from AARP.

Who does not pay Medicare premiums?

Most people do not pay a premium for Medicare Part A if they or their spouse worked and paid Medicare taxes for at least 10 years (40 quarters).

Almost everyone must pay a standard monthly premium for Medicare Part B, but certain groups receive financial assistance that covers or eliminates these costs.

  • You or your spouse worked and paid Medicare taxes for at least 10 years.
  • You are eligible for or receive Social Security or Railroad Retirement benefits.
  • You worked as a government employee in a job where you paid Medicare taxes.

Who Receives Help With Part B Premiums

While standard Part B premiums are required for most enrollees, specific programs pay the premium for low-income individuals:

  • Qualified Medicare Beneficiary (QMB) Program: State programs that pay Part A and/or Part B premiums, deductibles, and coinsurance for low-income individuals.
  • Specified Low-Income Medicare Beneficiary (SLMB) and Qualifying Individual (QI) Programs: State programs that help pay the Part B premium.
  • Medicaid: Low-income beneficiaries who qualify for both Medicare and full Medicaid receive assistance with their medicare costs.
  • Extra Help Program: Helps eliminate or reduce prescription drug plan (Part D) premiums for qualifying low-income individuals. You can check guidelines via the National Council on Aging.

What to do when Medicare refuses to pay?

When Medicare refuses to pay for a service, item, or drug, you can file a formal Filing an appeal to challenge the decision.

Steps to Take

  • Read the notice: Look at your Medicare Summary Notice (MSN) or the written denial notice from your plan to find the exact reason for the rejection and the specific deadline to appeal.
  • Check for errors: Contact your doctor or medical provider to see if the claim had a simple coding mistake or missing information that can be fixed and resubmitted.
  • File Level 1 (Redetermination): Submit a request for a redetermination to the Medicare Administrative Contractor (MAC) or your Medicare Advantage plan within the required timeframe (usually 120 days for Original Medicare or 60 days for plans).
  • Gather supporting documents: Include a letter explaining why you need the care, updated test results, or supporting notes from your doctor.
  • Continue through higher levels: If your first appeal is denied, you can move through the remaining steps of the Medicare Appeals process, which includes up to five levels depending on the claim amount.

Free Help and Resources

  • Contact your local State Health Insurance Assistance Program (SHIP) for free, one-on-one counseling and help with your paperwork.
  • Call 1-800-MEDICARE to ask questions about your specific claim status.

How do low-income people afford Medicare?

Low-income people afford Medicare through state and federal assistance programs like Medicaid, Medicare Savings Programs (MSPs), and the Part D Extra Help subsidy.

Major Assistance Programs

  • Medicaid ("Dual Eligibility"): Low-income individuals who qualify for both Medicare and Medicaid (known as dual-eligibles) have their Medicare premiums, deductibles, coinsurance, and copays paid or reduced by Medicaid. Medicaid also covers extra services that Medicare does not, such as long-term care or dental work.
  • Medicare Savings Programs (MSPs): State-operated programs that help pay for Part A and Part B costs based on income and asset limits:
    • QMB (Qualified Medicare Beneficiary): Pays Part A and Part B premiums, deductibles, and coinsurance.
    • SLMB (Specified Low-Income Medicare Beneficiary) & QI (Qualifying Individual): Help pay for the Medicare Part B monthly premium.
    • QDWI (Qualified Disabled and Working Individuals): Helps pay Part A premiums for disabled people who returned to work.
  • Extra Help (Low-Income Subsidy): A federal program that lowers prescription drug costs, eliminating or reducing Part D premiums, deductibles, and copays. Enrollees in Medicaid, Supplemental Security Income (SSI), or an MSP automatically qualify.
