Bulk billing and physio: what it actually means
Bulk billing is the most misunderstood word in Australian healthcare. Here is what it means, and why it works differently for physio than it does at the doctor.

Where the term comes from
Medicare sets a scheduled fee for a lot of health services. When a provider bulk bills, they agree to accept the Medicare rebate as the entire payment and bill Medicare directly, rather than charging you and having you claim it back. You hand over your Medicare card, you sign, and you pay nothing on the day.
The alternative is a private fee. The provider sets their own price, you pay it, and Medicare refunds a portion if the service is eligible. The difference between the fee and the rebate is what people call the gap.
Why physio is different from seeing your GP
Medicare covers GP visits broadly. It does not cover physiotherapy the same way. For most people, standard physiotherapy is a private service with no Medicare rebate at all.
Medicare only contributes to physiotherapy in specific circumstances. Most commonly that is a GP Chronic Condition Management Plan, still widely called a care plan or an EPC referral, which covers a limited number of allied health visits per calendar year.
So when someone asks whether a physio bulk bills, the real question underneath is usually: is there a way I can pay less than the full fee? Often there is.
The ways physio can cost you less
A GP care plan. If you have a long-term condition, your GP can refer you under a GP Chronic Condition Management Plan. Medicare then pays a set rebate towards each visit, up to an annual limit shared across all your allied health. Some clinics accept that rebate as full payment, which is bulk billing in practice. Others charge a gap. It varies by clinic, so ask.
DVA. Veterans with an eligible card are generally covered in full with no out-of-pocket cost, on referral.
Concession and pension rates. Many clinics charge a lower fee for pensioners and Health Care Card holders. This is a discount set by the clinic, not a Medicare rule.
WorkCover and TAC. If your injury is covered by an accepted claim, treatment is generally paid by the insurer rather than by you.
NDIS. If physiotherapy is in your plan, it is paid from your plan funding.
Private health extras. If your policy includes physiotherapy, you claim a rebate against the fee. With HICAPS you claim on the spot and pay only the difference.
Why fewer places bulk bill than people expect
The Medicare rebate for an allied health visit under a care plan is a fixed amount, and it has not kept pace with the cost of running a practice. A clinic that bulk bills every care plan patient absorbs that difference.
That is why bulk billing for physiotherapy is usually partial — offered to concession holders, or to care plan patients specifically, rather than to everyone. It is not a trick; it is arithmetic.
What to ask when you book
Three questions get you a clear answer every time: do I have a care plan referral, what will I pay on the day, and will I get anything back.
Ask them before your first appointment rather than after. Any reputable clinic will tell you the exact figure over the phone, and being told the cost upfront is something you are entitled to.
