Your general practitioner or psychaitrist will make the referral. Your general pracitioner prepares a GP Mental Health Treatment Plan. Allied mental health services under this initiative include psychological assessment and therapy services provided by clinical psychologists, and focussed psychological strategies services provided by appropriately qualified GPs and eligible psychologists, social workers and occupational therapists. If a provider accepts the Medicare benefit as full payment for the service, there will be no out-of-pocket cost. If not, you will have to pay the difference between the fee charged and the Medicare rebate.
