Does Medicare cover Prolia in North Carolina?

What Prolia is used for

Prolia is denosumab, an injection given under the skin once every six months. Its FDA label covers osteoporosis in postmenopausal women and in men at high risk of fracture, osteoporosis caused by steroid medicines, and bone loss from certain hormone treatments for prostate or breast cancer. The label says a health care provider should give it.

This page explains Medicare coverage only. Questions about whether Prolia is right for you belong with your prescriber.

Which part of Medicare covers Prolia

Who pays depends on where and how you get the shot:

• At your doctor's office: Part B, in most cases. Medicare.gov lists injectable osteoporosis drugs among Part B drugs and says Part B covers most injectable drugs when a licensed medical provider gives them. When the office stocks Prolia and gives you the shot, it bills Medicare under Part B.
• At home through home health: Part A or Part B. Medicare covers injectable osteoporosis drugs, and the home health nurse visit to give them, for a woman with osteoporosis who meets the criteria for Medicare home health services, has a fracture a provider certifies is related to postmenopausal osteoporosis, and can't give herself the injection (with no family member or caregiver able and willing to). You pay nothing for the nurse visit.
• Through a Part D plan, when Part B doesn't apply. Part D doesn't pay for a drug Part B covers in your situation, but some Part D plans list Prolia on their formularies for other cases. Ask your doctor's office and your plan how your shot will be billed before your appointment.

Is Prolia on Medicare's negotiated-price list?

No. Prolia is not among the drugs CMS has selected for the Medicare Drug Price Negotiation Program so far: the 10 drugs with negotiated prices since January 1, 2026, the 15 with negotiated prices starting January 1, 2027, and the 15 CMS selected on January 27, 2026, for prices that take effect in 2028.

Biosimilars

On March 5, 2024, FDA approved Jubbonti (denosumab-bbdz) as the first interchangeable biosimilar to Prolia, and has licensed more denosumab biosimilars since; FDA's Purple Book lists them. Under Part B, your doctor's office chooses the product it stocks. If you get it through a Part D plan at a North Carolina pharmacy, G.S. 90-85.28 lets the pharmacist dispense an interchangeable biosimilar in place of Prolia when it costs you less, unless your prescriber writes "Dispense as Written," and the pharmacy must tell your prescriber which product you got.

What you pay for Prolia

When Prolia is billed under Part B:

• Original Medicare: after the yearly Part B deductible, you generally pay 20% of the Medicare-approved amount for the drug. Original Medicare has no yearly out-of-pocket limit.
• Medigap: a Medigap policy can pay some or all of that Part B coinsurance, depending on the plan letter.
• Medicare Advantage: the plan sets its own cost sharing for Part B drugs, and in-network spending is capped by the plan's yearly maximum out-of-pocket limit (no higher than $9,850 in-network in 2027). Plans may require prior authorization or step therapy for Part B drugs.
• Inflation rebates: Medicare.gov notes you may pay lower coinsurance for certain Part B drugs whose prices rise faster than inflation. The list changes every quarter.

CMS publishes the 2027 Part B deductible with its yearly Part A and Part B fact sheet; see Medicare costs in 2027. If a Part D plan covers Prolia instead, the Part D rules apply: your plan's cost sharing, the 2027 Part D out-of-pocket cap of $2,400, the Medicare Prescription Payment Plan and Extra Help. See Extra Help in North Carolina.

Prolia in North Carolina: which coverage pays your share

Because Prolia is usually a Part B drug, your medical coverage matters more than your drug plan. With Original Medicare, you can get the shot from any provider who accepts Medicare and pay Part B coinsurance unless Medigap or other coverage pays it. With Medicare Advantage, you use the plan's network and may need prior authorization; every North Carolina county has Medicare Advantage plans open to everyone for 2027, from 11 in Carteret County to 57 in Guilford County.

Timing a shot every six months. If your Medicare Advantage plan is ending in 2027, choose new coverage by December 31, 2026, and confirm your provider is in the new plan's network so a scheduled dose isn't delayed. You also have a guaranteed right to buy certain Medigap plans for 63 days after the plan ends. North Carolina has no Medigap birthday rule or yearly switching right, so outside your first Medigap open enrollment or a guaranteed-issue right, a Medigap company can ask health questions. See Medigap in North Carolina and plans ending in 2027.

State Health Plan retirees. On the 70/30 Plan, Medicare pays first and the Plan may help pay some of the costs Medicare doesn't; the Plan says that without Part B it processes claims as if you had Part B, so keep Part B. On the Base Plan or Enhanced Plan (group Medicare Advantage), Part B drugs follow the Plan's rules. See State Health Plan retirees and Medicare.

Limited income. MQB-Q, North Carolina's name for the Qualified Medicare Beneficiary program, pays Part B deductibles and coinsurance as well as the premium. Apply through ePASS or your county Department of Social Services. See Medicare Savings Programs in North Carolina.

Checking your coverage for Prolia

1. Ask the office how it bills Prolia. Most offices that give Prolia bill it to Part B. If the office asks you to get it from a pharmacy instead, ask your Part D plan whether it covers Prolia and what rules apply.
2. Confirm your provider takes your coverage. With Original Medicare, ask whether the office accepts Medicare assignment. With Medicare Advantage, confirm the office is in the plan's network for 2027 and whether prior authorization is needed.
3. Know who pays your coinsurance. Medigap, a Medicare Advantage plan's out-of-pocket limit, the State Health Plan or MQB-Q can cover some or all of your Part B share.
4. 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.
