Yes, Medicare covers chemotherapy if you have cancer. What decides your out-of-pocket bill isn't whether you're covered, it's where the chemo is given. A doctor's office and a hospital bed are paid by two different parts of Medicare, and they cost you different amounts.

Does Medicare Cover Chemotherapy? The Short Answer
The short answer is yes. Medicare covers chemotherapy if you have cancer, and that coverage is spelled out on Medicare's own chemotherapy coverage page.Centers for Medicare & Medicaid Services. (n.d.). Chemotherapy Medical Coverage. medicare.gov. Retrieved Jul 17, 2026, from https://www.medicare.gov/coverage/chemotherapy
What Medicare doesn't do is pay for all of it out of one pocket. Which part of Medicare picks up the bill, and how much you owe, depends on where you're treated. So before you worry about the number, it helps to know which door your chemo comes through.
Part A vs. Part B: Where You Get Chemotherapy Decides Who Pays
Original Medicare has two halves, and chemotherapy can land in either one. Part B is the medical-insurance side, and it covers chemo given in a doctor's office, a freestanding clinic, or a hospital's outpatient department. Part A is the hospital-insurance side, and it only comes in when you're formally admitted as an inpatient.Centers for Medicare & Medicaid Services. (n.d.).

The line between the two comes down to one thing: whether you've been formally admitted to the hospital as an inpatient. If you haven't, your chemo runs through Part B, even when it's given inside a hospital's outpatient department. If you want to know which way a treatment will be billed, the billing office can tell you before you start.
Does Medicare Cover Chemotherapy in Full? What You'll Pay
Under Part B, the math is the standard outpatient formula. First you meet the annual Part B deductible, which is $283 in 2026. After that, you typically pay 20% of the Medicare-approved amount for the chemo drugs and the services that go with them, and Medicare covers the other 80%.Centers for Medicare & Medicaid Services.

Under Part B, the 20% coinsurance keeps applying to each round of treatment, so a long course of chemo can add up.Centers for Medicare & Medicaid Services. (n.d.). Chemotherapy Medical Coverage. medicare.gov. Retrieved Jul 17, 2026, from https://www.medicare.gov/coverage/chemotherapy It's the main reason a lot of people carry supplemental coverage alongside Original Medicare, and we'll get to that below.
There's one built-in guardrail if your chemo happens in a hospital outpatient department: your copayment for a single covered service there won't be more than the Part A inpatient hospital deductible, which is $1,736 in 2026.Centers for Medicare & Medicaid Services. (n.d.). Chemotherapy Medical Coverage. medicare.gov. Retrieved Jul 17, 2026, from https://www.medicare.gov/coverage/chemotherapy,Centers for Medicare & Medicaid Services.

And if you're admitted as an inpatient, chemo falls under Part A instead. There you pay the Part A inpatient hospital deductible, $1,736 per benefit period in 2026, rather than the 20% coinsurance. A benefit period starts the day you're admitted and ends once you've been out of the hospital for 60 days in a row, so a second stay later in the year can mean a second deductible.Centers for Medicare & Medicaid Services. (2026). 2026 Medicare Parts A & B Premiums and Deductibles. cms.gov. Retrieved Jul 23, 2026, from https://www.cms.gov/newsroom/fact-sheets/2026-medicare-parts-b-premiums-deductibles
Take-Home Chemo Pills: Part B or Part D?
Not all chemo comes through an IV. A lot of cancer treatment now comes as pills you take at home, and here's where Medicare splits one more time. Some oral cancer drugs are covered under Part B: Medicare covers oral anticancer drugs that meet its oral anticancer drug benefit criteria. Other oral cancer drugs are covered under your Part D prescription drug plan instead.Centers for Medicare & Medicaid Services. (n.d.). Chemotherapy Medical Coverage. medicare.gov. Retrieved Jul 17, 2026, from https://www.medicare.gov/coverage/chemotherapy
Which bucket your specific drug lands in matters, because the cost-sharing works differently in each. So it's worth asking two questions early: does my oncology team know whether this drug is billed under Part B or Part D, and what will my Part D plan charge if it's the drug side? Getting that straight before your first fill saves a surprise at the pharmacy counter.
How Medigap and Medicare Advantage Change Your Costs
Everything above describes Original Medicare, Part A and Part B, on its own. Two kinds of extra coverage change the out-of-pocket picture.
A Medigap policy, also called Medicare Supplement, is standardized supplemental insurance that pairs with Original Medicare. Premiums and benefits vary by plan letter (A-D, F, G, and K-N) and by carrier, so how much of your chemo cost-sharing it offsets depends on the plan you buy.Centers for Medicare & Medicaid Services. (2026). 2026 Medicare Parts A & B Premiums and Deductibles. cms.gov. Retrieved Jul 23, 2026, from https://www.cms.gov/newsroom/fact-sheets/2026-medicare-parts-b-premiums-deductibles
A Medicare Advantage plan (Part C) works differently. It runs on its own network and sets its own copays, but it also comes with an annual out-of-pocket maximum, federally capped at $9,250 for in-network care in 2026. Once you hit that ceiling, the plan covers the rest for the year. Keep in mind you still pay the standard Part B premium, $202.90 in 2026, on top of any plan premium.Centers for Medicare & Medicaid Services. (2026). 2026 Medicare Parts A & B Premiums and Deductibles. cms.gov. Retrieved Jul 23, 2026, from https://www.cms.gov/newsroom/fact-sheets/2026-medicare-parts-b-premiums-deductibles
Frequently Asked Questions
Does Medicare cover chemotherapy if I have cancer?
Yes. Medicare covers chemotherapy for people who have cancer. Part B covers it when it's given in a doctor's office, a freestanding clinic, or a hospital outpatient department, and Part A covers it when you're admitted to the hospital as an inpatient.
How much does chemotherapy cost with Medicare?
Under Part B, you first meet the annual deductible ($283 in 2026), then you typically pay 20% of the Medicare-approved amount while Medicare pays 80%. If the chemo is in a hospital outpatient department, your copay for a single service won't be more than the $1,736 inpatient deductible.Centers for Medicare & Medicaid Services. (n.d.). Chemotherapy Medical Coverage. medicare.gov. Retrieved Jul 17, 2026, from https://www.medicare.gov/coverage/chemotherapy,Centers for Medicare & Medicaid Services.

Are chemo pills covered by Medicare?
Yes, but through two different doors. Some oral cancer drugs are covered under Part B if they meet Medicare's oral anticancer drug benefit criteria; others are covered under your Part D drug plan. Ask your oncology team which one applies to your prescription.
Does Medicare cover chemotherapy in the hospital?
Yes. If you're admitted as an inpatient, chemotherapy is covered under Part A, and you pay the Part A inpatient hospital deductible ($1,736 per benefit period in 2026) rather than the 20% Part B coinsurance.Centers for Medicare & Medicaid Services. (n.d.). Chemotherapy Medical Coverage. medicare.gov. Retrieved Jul 17, 2026, from https://www.medicare.gov/coverage/chemotherapy,Centers for Medicare & Medicaid Services.

Is there a limit on what I'll pay for chemo?
Original Medicare's 20% coinsurance keeps applying no matter how high your treatment bill runs, which is why many people add a Medigap policy or choose a Medicare Advantage plan, which caps in-network out-of-pocket costs at $9,250 in 2026.Centers for Medicare & Medicaid Services.
