Chronic condition care plan (GP Management Plan and Team Care Arrangements)
Your next step
Book a longer GP appointment and ask whether a GP Management Plan (GPMP) and Team Care Arrangements (TCA) are right for you. If so, your GP prepares the plan and gives you a referral to a dietitian.
Your GP decides your eligibility and prepares the referral. Bulk billing and gap fees vary between dietitians, so ask when you book. The rebate is what Medicare pays back, not always the full fee.
