Medicare Part B covers bone-mass measurements, including a qualifying DEXA bone-density scan, when the benefit’s medical requirements are met. It is not an automatic annual test for everyone with Medicare.

Who may qualify?
Medicare lists several qualifying situations. These include a woman whose clinician determines she is estrogen-deficient and at risk for osteoporosis, X-rays suggesting osteoporosis, osteopenia or vertebral fractures, and a diagnosis of primary hyperparathyroidism. Certain treatment-related risk or monitoring situations can also qualify; your clinician must document the applicable condition.
Age alone, a family concern or a commercial screening package does not establish coverage. Ask your clinician which Medicare criterion applies and whether the record supports the order. This is an insurance explanation, not a recommendation to obtain testing or change treatment.
Frequency and patient cost
| Question | Coverage rule |
|---|---|
| How often? | Usually once every 24 months for an eligible person. |
| Can testing be earlier? | More often may be covered when medically necessary and documented. |
| What does the covered test cost? | No patient charge when the provider accepts Medicare assignment. |
| Is every service at the visit free? | No. Separate consultations or other tests may have their own costs. |
Arrange the test without billing surprises
- Tell the ordering office the date of your previous bone-density test.
- Ask the testing center to confirm the order and the applicable coverage requirements.
- Check that the provider accepts assignment; with Medicare Advantage, also verify the plan’s network and approval rules.
- If testing is earlier than the usual interval, ask what documentation supports medical necessity.
- Request the expected charge and read any notice explaining possible noncoverage before signing.
A billing code or a doctor’s order does not by itself guarantee payment. If a claim is denied, review the reason and the appeal instructions on the Medicare or plan notice. Ask the office to correct genuine billing errors rather than changing the stated reason for the test.
Coverage and test results are different questions
Only the treating professional can explain what your results mean for your health. A covered test does not establish coverage for every later service. Check each proposed service separately, including its provider, setting and any plan requirements.
