What Is Section 19AA — and How Is It Different From 19AB?

IMGs constantly confuse Section 19AA and Section 19AB of the Health Insurance Act 1973. They sound alike and both limit Medicare billing, but they are different rules with different triggers. Getting them straight tells you exactly what stands between you and unrestricted Medicare income.

The difference in one line

19AA is about your qualifications (you must be on a recognised training/fellowship path to bill Medicare); 19AB is about your geography (as an overseas-trained doctor you cannot bill in metro MM1 areas for 10 years without an exemption).

Section 19AA — the vocational-registration rule

Since November 1996, Section 19AA requires that, to access Medicare rebates at the full rate, a doctor must be one of:

• vocationally registered (e.g. on the RACGP or ACRRM vocational register), or
• a fellow of a recognised specialist college, or
• enrolled on an approved 3GA program — Australian General Practice Training (AGPT), the RACGP Practice Experience Program (PEP), the Fellowship Support Program (FSP), or a Remote Vocational Training Scheme placement.

This applies to every doctor who entered the profession after 1996 — Australian graduates included, not just IMGs. A new IMG generally satisfies 19AA by being placed on one of these programs while working toward fellowship.

Section 19AB — the 10-year IMG moratorium

Section 19AB is separate and applies specifically to overseas-trained doctors and foreign graduates of accredited medical schools. It restricts Medicare billing in well-serviced metro (MM1) locations for 10 years from your first billing date, unless an exemption (after-hours, DPA/regional, spousal, area of need) applies. Full explainer: Section 19AB.

How they stack

Both rules apply at once. A newly arrived UK or Indian GP must satisfy 19AA (by being on a recognised program) and work within 19AB (by using the after-hours exemption or a DPA location) to bill Medicare. Clear both and your billing is unrestricted.
