Yes, Medicare covers cancer treatment regardless of your age

Medicare does not stop covering cancer treatment when you turn 76 or any other age. If you are enrolled in Medicare Part A and Part B, chemotherapy, radiation, surgery, immunotherapy, and other cancer treatments are covered the same way they are for someone who is 65. Your age alone does not change what Medicare will pay for.

What does change as you age is how much you may pay out of pocket. After you meet your deductible, Medicare Part B covers 80 percent of approved cancer treatments, and you pay 20 percent. If you have a supplemental insurance plan (called Medigap) or a Medicare Advantage plan, your costs may be lower. But the treatment itself is covered.

Key Takeaways

  • Medicare Part A and Part B cover cancer surgery, chemotherapy, radiation, immunotherapy, and related hospital stays at any age, including after 76.
  • You pay 20 percent of the cost of outpatient cancer treatment after you meet your Part B deductible, which is set each year by Medicare.
  • If you have a Medigap plan, it typically covers some or all of your 20 percent share; if you have a Medicare Advantage plan, your costs depend on that plan's rules.
  • Cancer drugs covered under Part D (prescription drug coverage) have their own deductible and cost-sharing, separate from Part B.
  • Asking your oncologist's office which treatments are covered and what your share will be before starting treatment helps you plan for costs.

What Medicare Part A and Part B cover for cancer

Medicare Part A covers inpatient hospital stays for cancer surgery or treatment that requires an overnight stay. It also covers skilled nursing facility care if you need rehabilitation after treatment. Part B covers outpatient services: chemotherapy infusions at a hospital or clinic, radiation therapy, imaging scans, lab work, and visits with your oncologist.

Both parts cover the same treatments whether you are 50 or 90. There is no age limit on coverage, and Medicare does not require you to try less expensive treatments first because of your age. If your doctor recommends a treatment, Medicare's job is to determine whether it is medically necessary and approved by the Food and Drug Administration, not whether you are too old to receive it.

How much you pay for cancer treatment on Medicare

For Part B services (outpatient chemotherapy, radiation, and doctor visits), you pay a yearly deductible first—in 2024 this is $240, though the amount changes each year. After you meet the deductible, you pay 20 percent of the Medicare-approved amount for each service, and Medicare pays 80 percent. If your oncologist charges more than Medicare's approved amount, you may owe the difference.

For Part A (hospital stays), you pay a deductible per hospital stay—in 2024 this is $1,632—and then Medicare covers the rest for the first 60 days. After 60 days, you pay a daily coinsurance amount. These amounts also change yearly.

Cancer drugs given by injection or infusion at a clinic are covered under Part B. Oral cancer medications (pills you take at home) are covered under Part D, your prescription drug plan, which has its own deductible and cost-sharing rules.

Supplemental insurance and Medicare Advantage plans reduce your costs

If you have a Medigap (supplemental) plan, it pays some or all of the 20 percent you would otherwise owe for Part B services. The exact amount depends on which Medigap plan you chose when you enrolled. Plans G and N are the most common for people with ongoing medical needs, and they cover most or all of your Part B coinsurance.

If you have a Medicare Advantage plan instead of Original Medicare, your cancer treatment is still covered, but your costs work differently. Advantage plans have copays or coinsurance for each visit or service, and they have an out-of-pocket maximum—once you reach it in a calendar year, the plan pays 100 percent of covered services for the rest of that year. Your Advantage plan's formulary (list of covered drugs) may also limit which cancer medications are available to you or require prior authorization from the plan before treatment starts.

Prior authorization and coverage decisions

Some cancer treatments, especially newer immunotherapies or certain drug combinations, may require prior authorization. This means your oncologist's office must contact Medicare (or your Advantage plan) before starting treatment to confirm it is covered. This is not a denial—it is a verification step. Most prior authorizations are approved within a few business days.

If Medicare or your plan denies coverage for a treatment your doctor recommends, you have the right to appeal. Your oncologist's office can help file an appeal and provide medical evidence for why the treatment is necessary. Appeals can take several weeks, so it is important to start this process as soon as you learn of a denial.

Clinical trials and experimental treatments

Medicare covers routine care costs (chemotherapy, imaging, lab work, doctor visits) for patients enrolled in approved clinical trials, even if the trial drug itself is experimental. This means you can participate in cancer research without losing coverage for the standard parts of your treatment.

Experimental treatments outside of a clinical trial are generally not covered by Medicare. If your doctor believes an experimental treatment is your best option and it is not part of a trial, ask whether there is a clinical trial available or whether the treatment manufacturer offers a patient information program.

Questions to ask your oncologist about coverage

Before your first treatment, ask your oncologist's office these questions: Is this treatment covered by my Medicare plan? Will it require prior authorization? What is my out-of-pocket cost? Do I need to go to a specific facility or use a specific pharmacy? If you have a Medicare Advantage plan, also ask: Does my plan's formulary include this drug, or do I need prior authorization?

Bring your Medicare card and any supplemental insurance card to your first appointment. The billing office will verify your coverage and can often tell you your estimated cost before treatment begins. If the cost is higher than you expected, tell your doctor—there may be alternative treatments or financial information programs available.

Frequently Asked Questions

Does Medicare stop covering cancer treatment at a certain age?

No. Medicare covers cancer treatment for anyone enrolled in Part A and Part B, regardless of age. There is no age limit, and turning 76 or any other age does not change your coverage.

Will I pay more for cancer treatment because I am over 76?

Your age does not affect what Medicare pays or what you owe. Your costs depend on your deductible, coinsurance (20 percent for Part B), and whether you have supplemental insurance. These are the same for all Medicare beneficiaries.

What if my oncologist recommends a newer cancer drug?

Newer drugs approved by the FDA are covered by Medicare if they are medically necessary for your condition. Your doctor's office will check coverage and may need to get prior authorization. If the drug is oral (a pill), it is covered under Part D, which may have different cost-sharing than Part B infusions.

Can I get financial help if my cancer treatment costs are too high?

Yes. Pharmaceutical companies offer patient information programs for their drugs. The National Cancer Institute and American Cancer Society also have information about financial support and programs that help pay for treatment. Ask your oncologist's social worker or patient advocate for referrals.

What happens if Medicare denies coverage for my treatment?

You can appeal the denial. Your oncologist's office can file an appeal and provide medical evidence. Most appeals take several weeks. Ask your doctor to start the appeal when ready if coverage is denied, so treatment is not delayed.
