Medical Imaging Referral Online

A GP may request an X-ray, ultrasound or another medical imaging test when it is clinically appropriate after assessing your symptoms and history. Some MRI scans can be requested by GPs, while others require a specialist request for Medicare eligibility. An online doctor cannot safely order every test, and you may need a physical examination first.

What is a medical imaging request?

A medical imaging request asks a radiology service to perform a specified test for a clinical reason. It is not the same as a referral to a consulting medical specialist. The request should explain the symptoms, relevant findings and question the imaging is intended to answer.

The radiology provider reviews the request and applicable examination or funding requirements. The most useful test depends on what the doctor is trying to investigate, rather than on which scan seems most comprehensive.

When might a GP request an X-ray or ultrasound?

X-rays are commonly considered for certain bone and chest concerns. Ultrasound may be used to examine selected soft tissues, abdominal or pelvic structures, or other clinical questions. The doctor decides whether imaging is needed after assessing the likely benefits, limitations and risks.

Some problems are better assessed first with examination, observation or other investigations. A normal image also does not necessarily rule out every cause of a symptom.

Can a GP request an MRI or CT scan online?

GPs can request certain imaging examinations, but Medicare-funded MRI has particularly specific rules. Many MRI items require a request from a specialist or consultant physician; some items permit GP requests only for defined indications. For example, MBS Online notes that GP requests do not qualify for the listed cardiac MRI items.

CT imaging also requires clinical justification and consideration of ionising radiation exposure. Telehealth does not remove the need for examination or fulfil otherwise ineligible Medicare criteria. See MBS Online guidance for the important distinction between a diagnostic imaging request and specialist referral.

Will Medicare cover my radiology test?

Medicare eligibility varies by examination, indication, who requested the test, and the imaging provider. Some tests are fully covered by participating providers, while others involve a gap or may be privately billed. A doctor’s request is not a guarantee of a Medicare rebate.

Ask the radiology service for the expected cost, applicable MBS item and whether the examination meets the claiming rules before you attend. If a scan is not Medicare-eligible, your doctor can discuss whether another appropriate pathway is available.

When should I book in-person care instead of seeking imaging online?

A new injury with deformity, severe symptoms, loss of function, sudden neurological problems or other acute concerns may require urgent in-person examination. Your doctor may need to examine the painful area or assess neurological signs before deciding whether any scan is indicated.

If a test is arranged, check how results will be sent and who will review them with you. Results should be interpreted alongside symptoms and examination findings, not treated as a stand-alone diagnosis.
