I have a question regarding the validity of referrals sent via fax without a GP signature. All too frequently the GP gives the client the only signed hard copy and they either lose it or turn up without it. This leaves us chasing a referral. If the receptionist at the GP practice sends us a copy of the referral, they can only do so via fax without a GP signature. Current debate in the professional circles is underway again about whether a referral received via fax without a GP signature is indeed legal under Medicare.
