Medicare gives GPs standard rebates for their services on a per consultation basis. Longer consultations lead to higher rebates.
If you choose to take only this payment for your services, it is known as ‘bulk-billing’. When you are bulk-billing, a patient with a Medicare card pays nothing to you and you claim the rebate from the government.
If you decide to charge your patient for your services - instead of you claiming the rebate - the patient claims for it through Medicare. This can be done on the spot through an EFTPOS terminal or through Medicare directly, online or in-person.
