GP Referrals in Australia: Which Specialists Need One and Which Don't

Some specialists won't see you without a GP referral. Others will take walk-ins. The difference comes down to Medicare rules, and getting it wrong can cost you hundreds of dollars out of pocket.

Specialists that require a GP referral

Most medical specialists in Australia need a referral letter from your GP before they will book you in. Without one, Medicare will not pay any rebate on the consultation.

These specialists always require a referral:

• Cardiologist - heart and cardiovascular conditions
• Dermatologist - skin conditions, mole checks, skin cancer
• Gastroenterologist - digestive system, colonoscopies, liver
• Neurologist - brain, nerves, headaches, epilepsy
• Psychiatrist - mental health (medical specialist, not psychologist)
• Oncologist - cancer diagnosis and treatment
• Endocrinologist - hormones, diabetes, thyroid
• Rheumatologist - arthritis, autoimmune conditions
• Urologist - kidney, bladder, prostate
• Orthopaedic surgeon - bones, joints, sports injuries

A standard GP referral lasts 12 months. If your GP writes an indefinite referral, it stays valid until the specialist writes back to your GP, at which point a new referral cycle begins.

Health professionals that don't need a referral

You can book directly with these practitioners. No GP letter needed, no Medicare requirement:

• Dentist - book directly, Medicare does not cover general dental (except Child Dental Benefits Schedule, up to $1,095 over two years for eligible kids)
• Optometrist - bulk billed eye tests every 3 years (or annually if you have a condition), no referral needed
• Physiotherapist - book directly, though a GP referral gets you Medicare rebates under a Chronic Disease Management plan (up to 5 sessions per year, roughly $55 rebate each)
• Chiropractor - no referral needed, but no Medicare rebate either unless under a CDM plan
• Podiatrist - same as above, direct booking, Medicare rebates only through CDM plans
• Psychologist - you can self-refer, but a Mental Health Care Plan from your GP gives you 10 Medicare-rebated sessions per calendar year (rebate around $93 per session)

How the referral process works at the GP

Getting a referral is straightforward. Here is what happens at the appointment:

1. You describe your symptoms or concern. The GP assesses whether a specialist is appropriate.
2. The GP writes a referral letter. This includes your medical history, current medications, test results, and the reason for the referral. Most GPs type this during the appointment and print or send it electronically.
3. The letter goes to the specialist. Some GPs fax it directly. Others hand you a sealed envelope or email it. Many specialists now accept electronic referrals through secure messaging systems like HealthLink.
4. You call the specialist to book. Some specialist rooms will call you once they receive the referral. Others wait for you to ring. Always follow up within a week if you haven't heard back.

The GP consultation itself is typically bulk billed or costs $40 to $80 with a Medicare rebate of about $41 for a standard Level B consult. The referral letter is part of the consultation - there is no separate charge for writing it.

What happens if you skip the referral

Some specialists will still see you without a referral if you are willing to pay the full fee. But most will ask you to go back to your GP first. It is not just a Medicare rule - the referral letter gives the specialist critical information about your history and what the GP has already ruled out.

Private health insurance does not replace a Medicare referral. Even with top-level extras cover, the specialist consultation in their rooms is a Medicare matter, not a private health insurance matter. Private health insurance only kicks in for hospital admissions and some extras like dental and optical.

Emergency exceptions

If you go to a hospital emergency department, you do not need a referral. The ED will assess you, and if a specialist is needed, the hospital arranges it internally. This applies to all public hospitals.

If a specialist sees you in an emergency outside of a hospital setting (rare, but it happens), they can apply for a Medicare exemption. You should not be charged a gap for a genuine emergency consultation.

Ambulance officers and paramedics can also initiate specialist referrals in emergency situations.

Keeping your referral valid

A few things to keep in mind:

• Standard referrals last 12 months from the date the GP writes them
• If your GP writes "indefinite" or "ongoing", the referral lasts until the specialist reports back, then a new referral cycle starts
• If your referral expires before your appointment, call your GP and ask for a new one - most can reissue it over the phone or via their practice software
• You can take your referral to a different specialist if you change your mind - it is not locked to one doctor

The bottom line

If the practitioner has "Dr" in front of their name and works in a medical specialty, you almost certainly need a referral. If they are an allied health professional (physio, psychologist, podiatrist), you can book directly but will miss out on Medicare rebates unless your GP sets up a care plan first.

The 10-minute GP appointment to get a referral is worth it. It saves you hundreds on the specialist consultation and makes sure the specialist has your full medical picture before you walk in.
