For Referrers
Understanding MHTPs, Referrals, and Medicare Requirements
Updated with 1 Nov 2025 Changes
​
The Mental Health Treatment Plan (MHTP)
Expiry: A MHTP does not expire and patient's do not need a new MHTP every year. The MHTP remains active and valid until it is clinically appropriate for the GP to update it (e.g., due to changes in treatment needs, symptoms, diagnoses, GP review, etc.).
​
Billing: Referrers cannot bill a brand-new MHTP within a year of the most recent MHTP. Once the MHTP is billed to Medicare, the patient becomes eligible for Medicare rebates when referred to a psychologist.

​​​
Number of Sessions: While clients are eligible to receive up to 10 individual psychology sessions AND 10 group psychology sessions per calendar year, each referral is only valid for a maximum course of 6 sessions (see valid referral & examples lower on this page).
​
Valid Referrals
Referrals may be in letter form or simply a copy of the MHTP (as long as it contains all required elements below). Referrals do not expire but are only valid for as long as the number of sessions referred (maximum of 6).
​
For example, patient receives a referral for 6 sessions in 2025, and later a subsequent referral for an additional 6 sessions. The treating psychologist is responsible for ensuring that only 4 of these sessions are used in 2025. The remaining 2 sessions from that referral will carry over and can be used in 2026, before the client needs to return to their GP for a new referral.

Subsequent Referrals (From 1 Nov 2025)
​
From the 1st November 2025, there are no mental health specific review items (MBS Items 2712 and 2713 are discontinued).
Instead, GPs can use standard General Attendance items (e.g., MBS Item 23, 36 etc) to consult with the patient about their mental health, and issue any required re-referral for further psychology sessions.
A patient's Medicare rebate is only dependent on the MHTP date and item number (not the re-referral date). As long as a valid MHTP is in place, rebates will be processed by Medicare. Before processing rebates for patients, it is up to the treating psychologist to ensure that the client has a valid referral letter for each course of treatment.
