Get a DEXA bone density scan referral online

See a GP via telehealth and receive your DEXA referral by email when clinically appropriate. Medicare eligibility for the scan applies in specific circumstances.

What is a DEXA bone density scan?

DEXA (dual-energy X-ray absorptiometry) is a specialised imaging test that measures bone mineral density, most commonly at the hip and lower spine. The scanner uses a very low dose of X-rays, and the result is usually reported as a T-score, which compares your bone density to that of a healthy young adult.

DEXA is the standard test used in Australia to screen for and diagnose osteoporosis and to monitor response to treatment. It is quick, painless, and involves a lower radiation dose than a chest X-ray.

When a DEXA is ordered

Your GP may recommend a DEXA scan if you have risk factors for osteoporosis. These can include postmenopausal status, older age, a previous minimal-trauma fracture, long-term corticosteroid use, certain chronic illnesses, early menopause, family history of osteoporosis, or low body weight. Men with certain risk factors, including long-term hormone treatments, may also benefit.

Bone health is often considered alongside other aspects of midlife and later-life health, including menopause care and joint conditions such as osteoarthritis. Your GP will take a comprehensive history and decide whether a DEXA is the right next step.

Medicare eligibility for DEXA

Medicare rebates for DEXA are available in specific circumstances, including after a minimal-trauma fracture, for people on long-term corticosteroids, for those with certain endocrine, gastrointestinal, or chronic conditions that affect bone, and for people aged 70 and above. Follow-up scans to monitor treatment also fall under specific Medicare items.

If your circumstances do not meet Medicare criteria, a DEXA is usually still available, but may involve an out-of-pocket cost. Your GP will discuss which pathway is most appropriate, and the imaging provider can confirm costs at the time of booking.

How to get a DEXA referral online

Book a telehealth consultation with a NewDoc GP and discuss your risk factors, any previous fractures, and relevant medications. If your GP determines a DEXA is clinically appropriate, the referral will be emailed to you after the appointment. You can then attend any imaging centre that offers DEXA.

The telehealth consultation is bulk billed for eligible Medicare patients, regardless of whether the DEXA itself is Medicare-rebated. If your DEXA is ordered under a Medicare item, many providers bulk bill the scan, though this varies.

What to expect at the imaging provider

DEXA is available at many I-MED Radiology, Sonic Healthcare-affiliated, and other local imaging centres. On the day, you lie on a padded table while an imaging arm passes over your hip and lower spine. The scan is painless and usually takes only 10 to 20 minutes.

You will usually be asked to stop calcium supplements for 24 hours beforehand and to remove metal items. If you have had a recent CT scan with contrast, a barium study, or a nuclear medicine scan, tell your imaging centre, as DEXA may need to be rescheduled to avoid interference.

Understanding results

Your DEXA report includes a T-score, and often a Z-score, along with the radiologist's interpretation. Your NewDoc GP will review the report alongside your fracture history, risk factors, and any medications, to decide on a management plan. Not all low T-scores require medication.

Depending on your situation, management may include lifestyle advice such as weight-bearing activity, adequate calcium and vitamin D, smoking cessation, and falls prevention, along with medication where clinically appropriate. A repeat DEXA after a period of time helps your GP monitor progress.

When telehealth may not be suitable

Telehealth works well for assessing osteoporosis risk, arranging DEXA referrals, and reviewing results. However, if you have had a recent fall with significant pain, suspected fracture, or sudden severe back pain, you may need in-person assessment and imaging such as an X-ray. Book a bulk billed telehealth consultation to discuss whether a DEXA is appropriate for you.

Frequently asked questions

What is a DEXA scan?

A DEXA scan (dual-energy X-ray absorptiometry) is the standard test for measuring bone mineral density. It uses a low dose of X-rays, typically focused on the hip and lower spine, and provides a T-score that helps your GP assess bone health and the risk of osteoporosis and fracture.

Can I get a DEXA referral via telehealth?

Yes. Your NewDoc GP can assess your risk factors and any history of fractures during a telehealth consultation and issue a DEXA referral if clinically appropriate. The referral is emailed to you after the appointment, and you book at any imaging centre that offers DEXA.

Is a DEXA scan covered by Medicare?

Medicare rebates for DEXA scans apply in specific circumstances, such as after a minimal-trauma fracture, for people on long-term corticosteroids, or for those with certain medical conditions and risk factors. Your GP will discuss whether you meet Medicare criteria and, if not, what the out-of-pocket cost might be.

Is the consultation bulk billed?

Yes, for eligible Medicare patients. NewDoc bulk bills the telehealth consultation to Medicare at no out-of-pocket cost, regardless of whether the DEXA scan itself is rebated.

Do I need to prepare for a DEXA scan?

DEXA scans generally require little preparation. You may be asked to avoid calcium supplements for 24 hours before the scan and to wear clothing without metal fasteners, or to change into a gown. Tell your imaging centre if you have had a recent CT scan with contrast, a barium study, or a nuclear medicine scan, as these may affect timing.

How often should a DEXA be repeated?

Repeat DEXA frequency depends on your baseline result, risk factors, and treatment. For many people being monitored for osteoporosis, a repeat scan every one to two years is common, subject to clinical appropriateness and Medicare rules. Your GP will recommend a schedule that suits your situation.

What does the T-score mean?

The T-score compares your bone density to that of a healthy young adult. A T-score of -1.0 or above is generally considered normal, between -1.0 and -2.5 is described as osteopenia (low bone mass), and -2.5 or below is consistent with osteoporosis. Your GP will interpret the result alongside your fracture history and other risk factors.
