Medicare Chronic Disease Management Plan

Osteopathic treatment can be covered by Medicare if you are eligible for the Chronic Disease Management (CDM) care plan. You can be eligible for this if you are suffering from a chronic medical complaint. If you are eligible, you will need to visit your GP who will write up a referral. You can receive a maximum of five osteopathic consultations per year that Medicare will provide a rebate for. CDM referrals will be billed at our standard consultation fees, with the Medicare rebate being billed directly to Medicare so that you are only required to pay the gap payment.

Our Principle Four Osteopathy osteopaths are registered Workcover and TAC service providers. If you are claiming osteopathic care through Workcover or TAC, Principle Four Osteopathy requires accounts to be settled on the day of treatment.
