Do I need a diagnosis to access therapy?

Short answer: no. You do not need a formal diagnosis to access therapy in Australia.

Longer answer: it depends a bit on what kind of therapy and what kind of funding, but in most cases a diagnosis is not a prerequisite for getting support.

Therapy through Medicare

To access Medicare-rebated therapy, you need a Mental Health Treatment Plan from your GP. Your GP does not need to give you a specific diagnosis to create this plan. They just need to identify that you are experiencing mental health difficulties that would benefit from therapeutic support. You can walk in, explain how things have been for you, and your GP can create the plan based on that conversation.

Therapy through the NDIS

NDIS access does require a disability-related diagnosis, because the scheme is designed around disability. But if you are already an NDIS participant, you do not need a separate mental health diagnosis to access therapeutic support under your plan. Your goals just need to be connected to your functioning and your plan categories.

Private therapy

If you are paying privately, there are no requirements at all. You can see a therapist for any reason, with or without a diagnosis, with or without a referral.

Self-identification is valid

This matters especially for neurodivergent adults. Formal assessment can be expensive, hard to access, and for many people, simply not necessary. If you recognise yourself in descriptions of autism, ADHD, or other forms of neurodivergence, that self-knowledge is valid. Affirming therapy works with who you are, not with what paperwork you have.

If you are exploring whether you might be neurodivergent, therapy can be a useful space to do that exploration, regardless of whether you ever pursue a formal assessment.
