EPC stands for Enhanced Primary Care plan and TCA is a Team Care Arrangement. This basically means an arrangement between the GP, the dietitian and you. Medicare Australia has allowed GPs to refer to allied health practitioners when they have a patient with a chronic health condition. This scheme allows a person with a chronic health condition, like diabetes, to have five visits per calendar year shared over all health providers. For example you may have three appointments with a dietitian, one with a physio and one with a podiatrist = five appointments for the year. This enables you to get a rebate from Medicare like you would from your private health; the current rebate for a dietitian appointment is $52.95.
