Does my referral need to be addressed to the same psychologist?

Any referral or Mental Health Care Plan for a psychologist can be used with any psychologist.

If you've already got a GP referral and Mental Health Care Plan from your doctor but it's addressed to a different psychologist, such as a face-to-face provider, you can still use that with any psychologist. 

As long as the referral was addressed to a psychologist, you can use it with any psychologist.
