Medicare Osteoporosis Coverage: Tests, Drugs, Costs

Osteoporosis affects millions of older adults, and Medicare can help you screen, treat, and manage it without breaking the bank.

This guide breaks down what Parts A, B, D, and Medicare Advantage cover, how to keep costs down, and the steps to take so you don’t miss benefits you’re entitled to.

Medicare and Osteoporosis Care at a Glance

Original Medicare generally covers bone density testing, medically necessary treatments and therapies, and certain equipment that supports mobility and safety. Part D (or a plan with drug coverage) helps pay for most osteoporosis medications taken at home, while Part B may cover physician-administered or home health–administered injections in specific situations.

Medicare Advantage (Part C) plans must cover everything Original Medicare covers, and many include extras like integrated drug coverage, lower copays for specialists, and fitness programs that can support bone health. Your total costs depend on your plan, whether your providers accept assignment, and the specific drugs or services you use.

Part B: Bone Density Testing and Preventive Services

Part B covers bone mass measurements (most commonly a dual-energy X-ray absorptiometry, or DEXA scan) once every 24 months—or more often if medically necessary—for eligible beneficiaries. When your provider bills it as a preventive service and accepts assignment, you typically pay $0. You can confirm the benefit details on Medicare’s page for bone mass measurements.

You’re generally eligible if you meet one or more of these criteria your provider documents: you’re a woman with estrogen deficiency at risk for osteoporosis; you have vertebral abnormalities; you’re on long-term glucocorticoid (steroid) therapy; you have primary hyperparathyroidism; or you’re being monitored to check the response to an FDA-approved osteoporosis medication. Ask your doctor to note medical necessity in the order so the test is billed correctly.

Part D (and Drug Coverage in MA): Medications for Osteoporosis

Most osteoporosis drugs you take at home are covered under a Part D plan or a Medicare Advantage plan with drug coverage. Formularies vary, so check your plan’s list and tiers before you fill a prescription. Review the Part D basics here: what Part D drug plans cover.

Commonly covered medications

  • Oral bisphosphonates: alendronate, risedronate, ibandronate (often lower-cost generics)
  • Injectables and biologics: denosumab (Prolia), zoledronic acid (Reclast) when furnished by a provider or covered via your plan
  • Selective estrogen receptor modulators (SERMs): raloxifene
  • Anabolic agents: teriparatide (Forteo), abaloparatide (Tymlos) in some plans

Action step: Use the Medicare Plan Finder to compare plans by your exact drugs and pharmacy. Generics typically have lower copays, and many plans offer preferred pharmacy pricing.

Part B: Injectable Osteoporosis Drugs and Home Health

Medicare Part B may cover certain injectable osteoporosis drugs and the professional who administers them if you meet strict criteria. This often applies to postmenopausal women who’ve had a Medicare-covered fracture and are homebound or cannot self-administer the drug safely. In these cases, Part B can cover the medication and the home health nurse’s visit for injection. See the official policy for osteoporosis shots and related home health services.

When injections are administered in a doctor’s office (for example, Prolia every six months or an annual zoledronic acid infusion), they’re typically billed under Part B as a physician-administered drug, and you’ll usually owe 20% of the Medicare-approved amount after the Part B deductible—unless you have a Medigap plan or a Medicare Advantage plan with different cost-sharing. Always confirm prior authorization and site-of-care requirements.

Therapies and Equipment That Support Bone Health

Physical therapy

Medicare Part B covers medically necessary physical therapy ordered by your provider to improve strength, balance, and mobility after a fracture or to prevent falls. Annual therapy thresholds may apply, but there’s no hard cap when services are reasonable and necessary; expect standard Part B cost-sharing unless you have supplemental coverage.

Durable medical equipment (DME)

If you need orthotic supports such as certain back braces or other DME related to osteoporosis complications, Part B generally covers them when ordered by a physician and supplied by a Medicare-enrolled vendor. You typically pay 20% after the deductible. Review coverage for braces and orthotics and ask suppliers if they accept Medicare assignment to avoid surprise bills.

Medicare Advantage and Supplemental Options

Medicare Advantage (Part C) plans must provide all benefits of Original Medicare and often include extras: integrated drug coverage, lower copays for specialists, care coordination, and wellness programs (like SilverSneakers or similar) that can support bone health. Learn about MA basics here: Medicare Advantage plans.

Medigap (Medicare Supplement Insurance) helps pay Part A and B deductibles and coinsurance, which can be valuable if you expect ongoing imaging, injections, or therapy. Note: Medigap doesn’t include prescription drug coverage; you’d still need a Part D plan. Explore Medigap options.

What Will You Pay? Smart Ways to Lower Costs

  • Preventive DEXA billing: Ask your provider to bill DEXA as preventive when appropriate; if they accept assignment, your cost is typically $0.
  • Accepting assignment: Using providers and suppliers who accept assignment helps you avoid excess charges.
  • Choose cost-effective drugs: Talk with your clinician about generics or therapeutic alternatives on lower tiers. Recheck your plan annually during the Open Enrollment Period.
  • Financial help: If your income is limited, you may qualify for Medicare Savings Programs and Extra Help to reduce premiums and copays.
  • Plan networks and prior auth: For injections like Prolia or infusions, check network status and prior authorization rules before you schedule treatment.

FAQs: Medicare and Osteoporosis

How often does Medicare cover bone density tests?

Every 24 months for eligible beneficiaries, or more often if medically necessary. When billed as preventive by a provider who accepts assignment, your cost is typically $0. Details: bone mass measurements.

Are Prolia injections covered?

Often yes. When administered in a clinic, Prolia is typically covered under Part B with standard coinsurance. For qualifying homebound postmenopausal women with a Medicare-covered fracture, Part B may also cover the drug and a nurse to administer it at home. See osteoporosis shots.

Which drugs fall under Part D?

Most self-administered osteoporosis medicines (like oral bisphosphonates and SERMs) are under Part D. Exact costs depend on your plan’s formulary and tiering. Compare plans by your meds using the Plan Finder.

Is physical therapy covered?

Yes—when medically necessary and ordered by a provider, Part B covers therapy with standard cost-sharing. See physical therapy coverage.

Does Medicare Advantage offer additional benefits?

Many MA plans add perks beyond Original Medicare, such as integrated drug coverage, lower specialist copays, and wellness programs. Always compare premiums, networks, prior authorization rules, and your medications before enrolling.

Bottom Line

Medicare provides robust osteoporosis support—preventive DEXA scans, coverage for physician- or home-administered injections in qualifying cases, Part D drug coverage for at-home medications, and therapy and equipment when medically necessary. Review your specific plan, confirm that providers accept assignment, and compare drug coverage annually so you can get the right care at the lowest possible cost.
