The short answer: Medicare covers a lot more of addiction treatment than most Australians realise — public hospital detox, specialist addiction medicine consultations, Mental Health Care Plans for psychology sessions, and bulk-billed GP care all sit inside the Medicare system. What it doesn't cover is private inpatient rehab. Here's the detailed picture.
What Medicare fully covers
Public hospital detox and inpatient rehab
Public detox and rehabilitation through state and territory health systems is fully covered by Medicare for eligible Australians. There are no fees, no excess, no out-of-pockets. This includes hospital-based detox, dedicated public detox units, and public residential rehabilitation.
Access is via state alcohol and drug lines, GP referrals to local health district AOD services, hospital emergency presentations, and direct-to-service intake at community AOD clinics. The trade-off is wait times, not cost — non-urgent admissions to public detox typically run 1–4 weeks; public residential rehab can be 2–8 weeks.
Bulk-billed GP visits
Standard GP consultations are bulk-billed at most clinics for concession card holders and many other patients (varies by clinic). Non-bulk-billed standard GP consultations attract a Medicare rebate of approximately $42, leaving a typical out-of-pocket of $30–$60 depending on the clinic.
Your GP is often the most useful first call for addiction concerns. They can: assess severity, prescribe withdrawal medications for some substances, write a Mental Health Care Plan, refer you to public specialist services, prescribe relapse-prevention medications (naltrexone, acamprosate), and coordinate ongoing care.
Public addiction medicine specialist consultations
Addiction medicine specialists working in the public system — through hospitals, public addiction medicine clinics, and Local Health District services — are covered by Medicare. Consultations are free at the point of access through public clinics.
Private addiction medicine specialists charge fees with a Medicare rebate. Initial consultations typically cost $300–$500 with a Medicare rebate of approximately $130–$220, leaving an out-of-pocket of $150–$300+. Subsequent reviews are lower-cost.
Mental Health Care Plans
A Mental Health Care Plan, written by your GP, is one of the most useful tools available. It gives you up to 10 Medicare-rebated psychology sessions per calendar year (extendable to 20 with GP review).
Bulk-billing rates for psychology under Mental Health Care Plans vary. Many psychologists do not bulk-bill, charging $180–$280 per session with a Medicare rebate of approximately $93 (clinical psychologist) or $140 (psychiatrist), leaving out-of-pocket gaps of $50–$140 per session. Some psychologists charge less and bulk-bill in particular circumstances; community health centres often bulk-bill if they have psychology capacity.
Mental Health Care Plans also cover sessions with mental health social workers (10 sessions/year), occupational therapists with mental health specialty (10 sessions/year), and Aboriginal and Torres Strait Islander mental health workers in some settings.
For addiction, a Mental Health Care Plan + 10–20 sessions of CBT-based counselling with a psychologist is a clinically reasonable plan for mild-to-moderate dependence, particularly when paired with GP medical support and peer support (SMART Recovery, AA, NA).
Medication-assisted treatment
Most medications used in addiction treatment are subsidised through the Pharmaceutical Benefits Scheme (PBS):
- Methadone and buprenorphine for opioid dependence — PBS-subsidised, with dispensing fees that vary by pharmacy and dosing schedule.
- Long-acting buprenorphine injections (e.g. Sublocade, Buvidal) — PBS-listed for treatment of opioid use disorder.
- Naltrexone and acamprosate for alcohol — PBS-subsidised on prescription.
- Disulfiram for alcohol — available but rarely first-line; PBS-listed.
- Nicotine replacement therapy (patches, gum) — PBS-subsidised on prescription for some forms.
Standard PBS co-payment in 2026 is around $30 per script for general patients and around $7 for concession card holders. Some addiction medications have additional PBS authority requirements that your prescriber will manage.
What Medicare does NOT cover
The clearest exclusion is private inpatient rehab. Medicare does not contribute to private psychiatric or addiction inpatient stays. Whether a private health insurer covers some of the cost depends on the policy (see our private health insurance and rehab guide), but Medicare itself doesn't.
Other services not covered:
- Counselling sessions outside of a Mental Health Care Plan or workers covered by it.
- Group therapy programs run privately (though group programs in public services are covered).
- "Wellness" or "lifestyle" components of private rehab — yoga, equine therapy, art therapy when delivered as a private service.
- Accommodation costs in any private residential setting.
- Medications not on the PBS list (rare for evidence-based addiction medications, but possible for off-label use).
- Private psychiatry without a referral or beyond initial Medicare-rebated consultations.
Specific situations
If you're on Centrelink
Concession card holders pay reduced PBS co-payments (~$7 per script in 2026), reduced GP gap fees at most clinics (often bulk-billed), and have priority access to many subsidised NGO programs. Public services remain free regardless of concession status.
If you don't have Medicare
Crisis presentations to a public hospital emergency department are not refused for inability to pay. Public hospital detox can usually still be accessed, though billing arrangements differ. The state alcohol and drug lines can help navigate options for people without Medicare.
If you're an Aboriginal or Torres Strait Islander person
Aboriginal Community Controlled Health Organisations (ACCHOs) provide culturally appropriate care and have specific Medicare item numbers. Many Aboriginal-specific AOD services are partially or fully Medicare-funded with no out-of-pocket. The AODconnect directory lists culturally appropriate services nationally.
Practical advice
- Start with your GP. Bulk-billed where possible. Get a Mental Health Care Plan and a referral to public addiction medicine if appropriate.
- Call your state alcohol and drug line. Free, 24/7. They know what's Medicare-funded and what isn't, and can navigate access.
- Don't assume "Medicare doesn't cover rehab." Public rehab is one of the most comprehensive components of the Medicare system — it just requires patience with wait times and willingness to engage with state health services.
- Use the Mental Health Care Plan early. Even before any inpatient decision, getting started with a psychologist on a Plan is a useful first step that's substantially Medicare-funded.
