Medicare Part B covers Evenity, but only for certain patients and only when specific conditions are met
Evenity (romosozumab) is a bone-building injection used to treat osteoporosis in people at high risk of fracture. Medicare Part B will pay for it, but your doctor must document that you meet the criteria, and you will likely pay a copay or coinsurance. The drug is not automatically covered for everyone with osteoporosis — Medicare limits it to patients who have failed or cannot tolerate other osteoporosis treatments.
Coverage depends on three things: your doctor's documentation, whether you have tried other drugs first, and whether your specific situation matches Medicare's rules. This article explains what those rules are, what your doctor needs to do, and what to expect when you go to the pharmacy or infusion center.
Key Takeaways
- Medicare Part B covers Evenity injections for osteoporosis, but only after you have tried or cannot take other osteoporosis medications first.
- Your doctor must document in writing that you meet Medicare's coverage criteria before the pharmacy or infusion center will administer the drug.
- You will owe a 20 percent coinsurance after you meet your Part B deductible, unless you have supplemental coverage.
- Evenity is given as a monthly injection for one year, then you switch to a different osteoporosis drug for long-term maintenance.
- If Medicare denies coverage, you have the right to appeal, and your doctor can request a coverage review on your behalf.
What Medicare Part B requires before covering Evenity
Medicare will not pay for Evenity as a first-line treatment. You must have already tried at least one other osteoporosis drug — usually a bisphosphonate like alendronate (Fosamax) or risedronate (Actonel) — or your doctor must document that you cannot take those drugs because of a medical reason. Common reasons include severe kidney disease, inability to swallow pills, or a documented allergic reaction.
Your doctor also needs to show that you have a high fracture risk. This usually means you have had a recent fracture from osteoporosis, or your bone density test (DEXA scan) shows very low bone density, or you have multiple risk factors for fracture. Medicare's exact threshold changes, so your doctor will know whether your numbers meet the current standard.
Before your first injection, ask your doctor or their office staff to confirm that they have submitted the documentation Medicare needs. This step prevents delays at the pharmacy or infusion center and reduces the chance of a coverage denial.
How to get Evenity covered: the step-by-step process
Once your doctor decides Evenity is right for you, their office will send Medicare a request for coverage review. This request includes your medical history, your previous osteoporosis treatments, your bone density results, and any fractures you have had. Medicare reviews this information and sends a decision letter to your doctor, usually within a few business days.
If Medicare approves coverage, your doctor will write a prescription. You can fill it at a pharmacy that stocks Evenity, or your doctor may administer it in their office or at an infusion center. Evenity comes as a pre-filled pen that you inject under the skin once a month for 12 months.
If Medicare denies coverage, your doctor can request a peer-to-peer review, where a Medicare medical director speaks directly with your doctor about your case. Many denials are overturned at this stage. You also have the right to file a formal appeal, which your doctor's office can help you do.
What you will pay out of pocket
After you meet your Part B deductible for the year, you owe 20 percent coinsurance for each Evenity injection. The exact dollar amount depends on what your provider charges Medicare, which varies by region and by whether you receive it at a doctor's office, hospital outpatient department, or pharmacy. Ask your doctor's office or pharmacy for an estimate before your first dose.
If you have a Medigap (supplemental insurance) policy, it may cover some or all of your coinsurance. If you have Medicare Advantage, your out-of-pocket costs depend on your specific plan — some plans cover Evenity with a copay instead of coinsurance, and some require prior authorization. Call your plan before your first injection to confirm your cost.
Evenity is expensive, and the monthly cost can add up over the year. If cost is a concern, ask your doctor whether the drug manufacturer offers a patient information program that can help reduce your out-of-pocket expense.
The 12-month Evenity course and what comes after
Evenity is designed as a one-year treatment. You receive one injection every month for 12 months. After the 12 months are complete, you do not continue Evenity — instead, your doctor will switch you to a different osteoporosis drug for long-term maintenance, usually a bisphosphonate or a different class of drug.
This switch is important because Evenity works by building bone quickly in the first year, but it is not meant for indefinite use. Your doctor will discuss the next step with you before your 12 months end. Medicare covers the maintenance drug the same way it covers other osteoporosis treatments, so your out-of-pocket costs may be lower than they were for Evenity.
When Medicare might deny Evenity coverage
Medicare denies Evenity coverage most often when your doctor has not documented that you tried another osteoporosis drug first, or when your bone density or fracture risk does not meet Medicare's threshold. Other reasons include incomplete medical records, a diagnosis that does not match Medicare's approved uses, or a prior authorization that expired.
If you receive a denial letter, read it carefully — it will explain the specific reason. The most common fix is for your doctor to submit additional medical records or a letter explaining why you could not take the first-line drug. Many denials are reversed on appeal, especially if your doctor's office handles the appeal for you.
Questions to ask your doctor before starting Evenity
Before your first injection, ask your doctor these questions: Have you submitted the coverage request to Medicare? How long does Medicare usually take to respond? What is my estimated out-of-pocket cost per injection? Do I have any other osteoporosis drugs I should try first? What happens after the 12 months of Evenity? What side effects should I watch for, and when should I call you?
Also ask whether your doctor's office will handle any Medicare appeals if coverage is denied. Some offices do this routinely; others expect you to handle it yourself. Knowing this in advance saves time and frustration if a denial happens.
Frequently Asked Questions
Does Medicare Part D cover Evenity instead of Part B?
No. Evenity is covered only under Medicare Part B because it is an injectable drug administered in a medical setting, not a pill you take at home. Part D covers oral osteoporosis drugs like alendronate and risedronate. If your doctor prescribes Evenity, it will be billed to Part B, not Part D.
What if I have Medicare Advantage instead of Original Medicare?
Medicare Advantage plans must cover Evenity if Original Medicare would cover it, but your out-of-pocket costs and prior authorization rules may differ. Contact your plan before your first injection to confirm coverage and ask whether you need prior authorization from your plan before your doctor submits the request to Medicare.
Can I get Evenity if I have never taken an osteoporosis drug before?
Probably not, unless your doctor documents a medical reason you cannot take standard first-line drugs. Medicare requires evidence that you have tried or cannot tolerate another osteoporosis treatment. Your doctor can explain whether an exception applies to your situation.
What should I do if Medicare denies my Evenity coverage?
Ask your doctor's office to request a peer-to-peer review with a Medicare medical director. If that is denied, you can file a formal appeal. Your doctor's office can help with both steps. Many denials are overturned when your doctor provides additional documentation or explains why you need Evenity instead of other drugs.
Will I need prior authorization every month, or just once?
Usually just once. Medicare approves Evenity for the full 12-month course when coverage is granted. However, if there is a gap in your treatment or if your insurance changes, you may need new authorization. Your doctor's office will let you know if this happens.
