Bone density tests (also called bone mineral density tests or bone scans) evaluate the strength of your bones by measuring a small part of one or a few bones. Knowing the strength of your bones can help your doctor recommend prevention steps and osteoporosismedication, if needed, to prevent bone loss and fractures.
According to National Osteoporosis Foundation guidelines, there are several groups of people who should consider bone density testing:
All postmenopausal women below age 65 who have risk factors for osteoporosis.
All women aged 65 and older.
Postmenopausal women with fractures; this is not mandatory because treatment may be started regardless of bone density.
Women with medical conditions associated with osteoporosis. Your health care provider can tell you if you have a medical condition associated with osteoporosis.
Women whose decision to use medication might be aided by bone density testing.
Men age 70 or older.
Men ages 50-69 with risk factors for osteoporosis.

Does Insurance Cover the Cost of a Bone Density Test?
Many health insurance companies cover the cost of a bone density test, as does Medicare. But you need to check ahead of time to see if the test is covered under your specific plan (or if you qualify according to Medicare's criteria for who is eligible for testing).
Most health insurers will pay for this test if you have one or more risk factors such as:
You are postmenopausal
You are not taking estrogen at menopause
You are taking medications that cause bone thinning
Medicare covers bone density testing for the following individuals aged 65 and older:
Estrogen-deficient women at risk for osteoporosis
Individuals with spinal abnormalities
Individuals receiving, or planning to receive, long-term glucocorticoid (steroid) therapy
Individuals with primary hyperparathyroidism
Individuals being monitored to assess the response or efficacy of an approved osteoporosis drug therapy
Medicare permits individuals to repeat bone density testing every two years.
