What Imbruvica is used for
Imbruvica is a kinase inhibitor taken by mouth (capsules, tablets or oral suspension). Its FDA label covers chronic lymphocytic leukemia and small lymphocytic lymphoma, Waldenström's macroglobulinemia, and chronic graft-versus-host disease after a stem cell transplant.
This page explains Medicare coverage only. Questions about whether Imbruvica is right for you belong with your prescriber.
Which part of Medicare covers Imbruvica
Imbruvica is an oral drug, so it's covered by Part D. Part B covers some oral cancer drugs, but only when the same drug is also available as an injection or infusion; ibrutinib isn't, so Part D it is. Plans may require prior authorization and may send the prescription to a specialty pharmacy.
Is Imbruvica on Medicare's negotiated-price list?
CMS selected Imbruvica in the first round of the Medicare Drug Price Negotiation Program. Its negotiated price (the "maximum fair price") took effect January 1, 2026, and Imbruvica is still on CMS's selected drug list for 2027. A negotiated price is what Medicare drug plans and pharmacies pay; it isn't your copay. What you pay still depends on your plan's cost sharing.
Protected class: what it means for Imbruvica
Medicare rules (42 CFR 423.120) require Part D plans to cover all or substantially all drugs in six protected classes, and antineoplastics (cancer drugs) are one of them. That makes it very likely any Part D plan you choose covers ibrutinib, but plans can still differ on the tier, prior authorization and which pharmacy you must use. Check those details for Imbruvica on each plan before you enroll.
What you pay for Imbruvica in 2027: the out-of-pocket cap
Your cost for Imbruvica depends on your plan: its deductible, the tier it puts the drug on, and whether you use a preferred pharmacy. This site doesn't list plan costs; your plan's formulary and Evidence of Coverage do. What Medicare sets for everyone with Part D is the limit:
- 2027 out-of-pocket cap: $2,400 (it was $2,100 in 2026). Once what you pay for covered Part D drugs (deductible, copays and coinsurance) reaches the cap, you pay nothing more for covered Part D drugs for the rest of 2027.
- The maximum Part D deductible for 2027 is $700. No plan can set a higher deductible, and some have none.
- Only covered drugs count. If your plan doesn't cover Imbruvica and you pay cash, or you use a discount card instead of your plan, that spending doesn't count toward the cap.
Spreading the cost: the Medicare Prescription Payment Plan
Every Part D plan and Medicare Advantage plan with drug coverage offers the Medicare Prescription Payment Plan. Instead of paying the pharmacy, you get a monthly bill from your plan that spreads your costs across the calendar year. Medicare.gov says there's no cost to participate and no interest, but it doesn't lower your drug costs; it only changes when you pay. It helps most when costs are high early in the year. To join, call your plan or use its website. More in What is the Medicare Prescription Payment Plan?
Extra Help with Imbruvica
Extra Help (the Low-Income Subsidy) is a federal program that lowers Part D premiums, deductibles and copays. For 2027, CMS caps Extra Help copays for covered drugs at $5.80 for a generic and $14.40 for a brand-name drug, and some people with full Medicaid pay less. You get Extra Help automatically if you have Ohio Medicaid, a Medicare Premium Assistance Program (Ohio's name for the Medicare Savings Programs) or SSI; otherwise apply through Social Security at 1-800-772-1213 (TTY 1-800-325-0778) or ssa.gov/extrahelp. See Extra Help in Ohio.
Getting Imbruvica covered in Ohio
Ohio is its own Part D region (PDP Region 14; no other state shares it), so each standalone Part D plan sold in Ohio is offered in all 88 counties. For 2027, CMS lists 9 standalone Part D plans from 5 companies in Ohio, and 119 Medicare Advantage plans open to everyone are offered across the state; CMS data show Medicare Advantage plans with drug coverage in every Ohio county for 2027. Each plan has its own formulary, so one plan's coverage of Imbruvica tells you nothing about another's. Your county's numbers are on Ohio counties.
If you have full Ohio Medicaid and Medicare, your prescriptions are paid by your Medicare drug coverage, not by Ohio Medicaid, and you get Extra Help automatically. In MyCare Ohio, your Medicaid plan is assigned but the Medicare side is your choice; choosing the same MyCare plan for Medicare puts your drug coverage in that one plan. See MyCare Ohio.
If your Medicare Advantage plan ends in 2027, you have a special enrollment period through February 28, 2027; choose new drug coverage by December 31, 2026, to avoid a gap. See plans ending in 2027.
If you run out and can't reach your prescriber, Ohio law (ORC 4729.281) lets a pharmacist refill a non-controlled drug you take regularly when going without it could harm you: the first time up to a 30-day supply, then shorter supplies, no more than three times in 12 months. Whether your plan pays for that fill depends on its rules. See early refills before a winter storm.
How to check whether a plan covers Imbruvica
- Write down the exact drug. Name, strength and how often you take it. A plan can cover one form or strength of Imbruvica and not another.
- Look it up in each plan's formulary. Enter your drugs and ZIP code on PlanMatch or Medicare.gov's Plan Finder to see which plans list Imbruvica and any rules.
- Read the rules next to the drug. Prior authorization, step therapy or quantity limits mean your prescriber may need to send the plan information before it pays.
- Check your 2027 notice. Your plan's Annual Notice of Change says whether Imbruvica stays on the formulary next year. Open Enrollment runs October 15 to December 7, 2026, for coverage starting January 1, 2027.
- Get help if you want it. You can request a call from a licensed insurance agent, who can compare plans from the companies they work with, or call 1-800-MEDICARE (1-800-633-4227, TTY 1-877-486-2048) for information on all of your options.
If your plan doesn't cover Imbruvica, you or your prescriber can ask for a coverage determination or a formulary exception. Once the plan has your prescriber's supporting statement, it generally must decide within 72 hours, or 24 hours if your prescriber says waiting could seriously harm your health. New members can usually get a one-time transition supply of a drug they were already taking while they ask for an exception or switch. See How do I appeal a Medicare denial in Ohio?

Frequently asked questions
Do Part D plans have to cover Imbruvica?
Cancer drugs are a protected class, so Part D plans must cover all or substantially all of them. Plans can still set the tier, prior authorization and pharmacy rules.
Does Imbruvica have a Medicare negotiated price?
Yes. CMS negotiated a price for Imbruvica in the first round, effective January 1, 2026, and it remains a selected drug for 2027.
Does the 2027 Part D out-of-pocket cap apply to Imbruvica?
Yes, when your Part D plan covers Imbruvica. In 2027, once you've paid $2,400 for covered Part D drugs, you pay nothing more for covered Part D drugs for the rest of the year.
What if my plan doesn't cover Imbruvica?
Ask the plan for a coverage determination or formulary exception, with a supporting statement from your prescriber, or compare plans during Open Enrollment, October 15 to December 7. New members can usually get a transition fill while they ask.
