Bone Density: Time to
Get It Tested
Bone Mass Measurement (BMM), or bone density screening is a test that
identifies bone mass, detects bone loss, and may determine bone quality. BMM
can be performed with a bone 'densitometer' or an approved bone 'sonometer
system.' Bone densitometry uses an X-ray or some other form of radiation, and
the test will determine your bone density according to the rate at which this
radiation is absorbed by your bones. There are usually three methods of
testing: a stationary machine kept in one location, such as your doctor’s
office or a hospital; a mobile unit, such as you see with mammography units, or
with a portable machine. Bone sonometers are ultrasound machines and do not use
radiation. You often see these machines in doctors’ offices. This is the same
ultrasound technique used for gallbladders, bladders, etc.
Medicare may cover BMM screening once every two years (at least 23 months have
passed since the month the last covered BMM was performed) or more often when
medically necessary for persons who are at risk for osteoporosis and meet other
conditions. This test is free (deductible and coinsurance/copayment are waived)
if your doctor or health care provider accepts assignment. To 'accept
assignment' means your doctor or health care provider or suppler has a signed
agreement to be paid directly by Medicare and to accept the Medicare approved
amount. They cannot bill you for any more than the Medicare deductible and
coinsurance.
Medicare covers bone mass measurement when:
• It is ordered by a physician or qualified health
care practitioner who is treating you, following an evaluation of the need for
the BMM
