No. You do not need a medical doctor referral to see your Chiropractor. Chiropractors are primary health care practitioners therefore a referral is not necessary.
However, more and more GP’s are referring patients to Chiropractors via the EPC (Enhanced Primary Care Program). This will normally allow a patient with a chronic or longstanding problems to visit a chiropractor for up to five visits. These five visits can be claimed back on Medicare.
