Is Prolia Covered Under Medicare Part B Or D?
If you are considering treatment with Prolia, a medication commonly used for osteoporosis, understanding your Medicare coverage options is essential. Prolia (denosumab) is a prescription drug that comes with significant costs, so knowing whether it's covered under Medicare Part B or Part D can greatly influence your out-of-pocket expenses. This comprehensive guide will explore how Prolia is covered under Medicare, providing insights into the distinctions between Part B and Part D coverage, eligibility requirements, related costs, and other relevant factors.
Understanding Prolia and Its Medical Use
Prolia is a prescription medication used for the treatment of osteoporosis, primarily in postmenopausal women who are at high risk for bone fracture. It is also used to increase bone mass in men with osteoporosis. Prolia works by inhibiting the development and activity of osteoclasts, cells that break down bone in the body, effectively increasing bone mass and strength.
Medicare Coverage Overview
Medicare, the federal health insurance program for people aged 65 and over and some younger individuals with disabilities, consists of several parts:
- Medicare Part A (Hospital Insurance): Covers inpatient hospital stays, care in a skilled nursing facility, hospice care, and some home health care.
- Medicare Part B (Medical Insurance): Covers certain doctors' services, outpatient care, medical supplies, and preventive services.
- Medicare Part D (Prescription Drug Coverage): Provides prescription drug coverage to help lower your prescription drug costs and protect against higher costs due to catastrophic coverage.
Is Prolia Covered Under Medicare Part B or D?
Coverage Under Medicare Part B
Prolia is most commonly covered under Medicare Part B. This is because Medicare Part B often includes coverage for medications administered by a healthcare professional, such as injections and infusions in a clinical setting.
- Medical Necessity: For Prolia to be covered under Part B, it must be deemed medically necessary. This means a healthcare provider must certify that Prolia is needed to treat or prevent osteoporosis in a patient who is at high risk for fractures.
- Administration Requirement: Prolia is administered through an injection given every six months. Because this administration is typically conducted in a physician's office or a clinical setting, it falls under the purview of Part B.
- Cost Implications: Patients may be responsible for 20% of the Medicare-approved amount for Prolia after meeting the Part B deductible. It is advisable to verify with specific Medicare plans as coverage nuances may apply.
Coverage Under Medicare Part D
While Prolia is generally covered under Part B, there are instances where it could be covered under Part D, but this is much less common.
- Part D Coverage Availability: Part D usually covers prescription medications that a patient can self-administer. As Prolia requires healthcare provider administration, it generally does not fall within typical Part D coverage.
- Plan Flexibility: Some Part D plans might include certain injections if not administered in a healthcare setting. Check with your specific Part D plan to confirm any exceptions or additional coverage.
- Cost Considerations: Coverage under Part D would entail different costs, including the possibility of higher co-pays or deductibles, as plans vary significantly.
Key Considerations and Additional Costs
Regardless of whether Prolia is covered under Part B or Part D, consider additional costs that may apply, such as supplemental insurance policies that can help cover out-of-pocket expenses not covered by Medicare. Plans like Medicare Supplement Insurance (Medigap) can help to cover costs such as deductibles, coinsurance, and copayments:
- Medigap Plans: These are standardized plans available in most states and can help cover some costs not covered by Original Medicare. However, Medigap does not work if Medicare Advantage covers you.
- Medicare Advantage Plans: Some individuals may have Medicare Advantage (Part C) plans that offer specific Prolia coverage, possibly under different terms than Original Medicare. However, these can vary widely between providers.

Frequently Asked Questions (FAQs)
1. What if my Medicare plan does not cover Prolia or the costs are too high?
If your plan does not fully cover Prolia or you face high costs, consult with your healthcare provider about alternatives or financial assistance programs offered by Amgen, Prolia's manufacturer, which sometimes provides assistance to eligible patients. Additionally, checking with all available supplemental options or different Medicare Advantage plans might present other solutions.
2. How can I determine if my Prolia prescription is covered under my specific Medicare plan?
The best approach is to contact your Medicare plan directly. Provide the plan administrator with the specifics of your prescription and check for any special restrictions, eligibility requirements, or alternative plan options that might better suit your needs.
3. Are there any side effects or contraindications I should know before starting Prolia?
As with any medication, Prolia has potential side effects, including low calcium levels, skin issues, and increased risk of infections. Discuss potential side effects and any contraindications with your healthcare provider to determine if Prolia is suitable for you.
4. Can I receive Prolia at home, and will it still be covered under Medicare Part B?
Prolia is typically administered in a healthcare setting. Home administration would not usually fall under Medicare Part B coverage unless specifically arranged under special circumstances through a registered nurse or healthcare provider with appropriate documentation proving medical necessity. Check with your provider for specific arrangements.
