Does Medicare cover Imbruvica in Oregon?

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 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.
• 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.

With a drug like Imbruvica, the cap is likely reached early in the year. If paying that amount in January or February is hard, the Medicare Prescription Payment Plan below spreads it across the months instead.

Spreading the cost: the Medicare Prescription Payment Plan

The Medicare Prescription Payment Plan lets you pay your Part D drug costs in monthly bills from your plan across the calendar year instead of all at once at the pharmacy. Medicare.gov says there's no cost to participate, 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 OHP (Medicaid), a Medicare Savings Program or SSI; otherwise apply through Social Security at 1-800-772-1213 or ssa.gov/extrahelp. See Extra Help in Oregon.

Getting Imbruvica covered in Oregon

Where you live in Oregon changes your choices. CMS data show no Medicare Advantage plan open to everyone in Grant, Harney, Lake, Umatilla or Union counties for 2027 (only employer group plans), and only a special needs plan in Curry County. If you live there, coverage for Imbruvica usually comes from a standalone Part D plan alongside Original Medicare, unless you have employer or other drug coverage. Check your county's numbers on Oregon counties.

If you have both Medicare and OHP, OHP doesn't pay for drugs that Part D covers. The Oregon Health Authority calls this "OHP with Limited Drug": you need a Part D plan (or a Medicare Advantage plan with drug coverage) for Imbruvica, and you qualify for Extra Help automatically. See OHP and Medicare.

Oregon and Washington share Part D region 30, so standalone Part D plans are offered region-wide. For 2027, Oregon has 8 standalone Part D plans from 4 companies, plus Medicare Advantage plans with drug coverage in most counties (61 open to everyone statewide). Each plan has its own formulary, so one plan's coverage of Imbruvica tells you nothing about another's.

How to check whether a plan covers Imbruvica

1. Write down the exact drug. Name, strength and how often you take it. A plan can cover one form of Imbruvica and not another.
2. 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.
3. 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.
4. 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.
5. 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 Oregon?
