Choosing between private billing and bulk billing is one of the most consequential decisions for any GP practice. Your billing model affects patient demographics, revenue potential, appointment volumes, staffing requirements, and long-term practice sustainability. There is no single correct answer, as the right model depends on your location, patient population, financial goals, and clinical philosophy.
Speak with our Regulatory Growth team to get a detailed financial analysis of which billing model suits your practice.
Understanding Bulk Billing
Under a bulk billing model, the GP accepts the Medicare rebate as full payment for a service. The patient pays nothing out of pocket. The practice receives the Medicare benefit directly from Services Australia, typically within a few days of claim submission. Bulk billing is straightforward for patients and eliminates the need for the practice to manage patient payments, chase outstanding accounts, or process refunds.
The primary advantage of bulk billing is patient accessibility. Practices that bulk bill attract larger patient volumes, including families, concession card holders, and patients who would otherwise delay or avoid seeking care due to cost. The Bulk Billing Incentive (BBI) payments from the government provide additional revenue on top of the standard Medicare rebate for eligible patient groups, particularly in regional and rural areas.

Understanding Private Billing
Private billing (also called fee-for-service or gap billing) allows the GP to set their own consultation fees above the Medicare rebate. The patient pays the full fee to the practice and then claims the Medicare rebate from Services Australia, or the practice can process the Medicare claim on the patient’s behalf and collect only the gap payment.
The primary advantage of private billing is higher revenue per consultation. A private billing GP can earn significantly more per appointment than a bulk billing GP, which means fewer patients per day can achieve the same or higher total revenue. This allows for longer consultations, more thorough care, and a potentially more sustainable work-life balance.
However, private billing introduces administrative complexity. The practice must manage fee schedules, patient payments (EFTPOS, invoicing), gap payment explanations, and potential bad debts. Some patients may resist gap payments, and fee transparency is essential to maintaining trust and avoiding complaints.
Mixed Billing: The Middle Ground
Many practices adopt a mixed billing model, where specific patient groups are bulk billed while others are privately billed. Common mixed billing approaches include bulk billing concession card holders and children under 16 while privately billing other patients, bulk billing all patients for standard consultations but privately billing for longer or complex consultations, and bulk billing during specific hours (for example, weekday mornings) while privately billing at other times.
Mixed billing allows practices to balance patient access with revenue optimisation. However, it requires clear communication with patients about when fees apply and consistent implementation across all practitioners in the practice.
Financial Comparison: Bulk Billing vs Private Billing
Revenue per Consultation
For a standard Level B consultation (MBS Item 23), the Medicare rebate is the sole income under bulk billing. Under private billing, the practice charges its own fee (commonly $80 to $120 for a standard consultation), and the patient claims the Medicare rebate separately. The difference between the practice fee and the Medicare rebate is the patient’s out-of-pocket cost (the “gap”).
Patient Volume Requirements
Bulk billing practices typically need to see 30 to 45 patients per GP per day to achieve target revenue. Private billing practices can achieve equivalent revenue with 20 to 30 patients per GP per day, allowing for longer appointments and more comprehensive care. The volume difference has significant implications for practitioner wellbeing, clinical quality, and staffing needs.
Overhead Considerations
While private billing generates higher revenue per consultation, it may also involve higher overheads. Additional reception staff time is needed for payment processing, fee explanations, and account management. EFTPOS terminal costs, statement generation, and bad debt write-offs add to the expense. Bulk billing practices have simpler billing workflows but need the infrastructure to handle higher patient volumes efficiently.
Location and Demographic Factors
Your practice location strongly influences which billing model will succeed. In areas with high socioeconomic demographics and strong private health insurance coverage, patients expect and accept gap payments. In lower socioeconomic areas, bulk billing may be essential to attract and retain patients.
Regional and rural areas benefit from higher BBI payments, making bulk billing more financially viable than in metropolitan centres. The Modified Monash Model (MMM) classification of your location determines the BBI rate, with MMM 2-7 areas receiving substantially higher incentives than MMM 1 (major city) areas.
Consider also the competitive landscape. If surrounding practices bulk bill, introducing private billing may be difficult unless you can clearly differentiate your service offering. Conversely, in an area saturated with private billing practices, bulk billing can attract a large, loyal patient base quickly.
Impact on Practice Incentives and Government Programs
Your billing model affects eligibility for certain government incentive programs. The Practice Incentives Program (PIP) is available to all accredited practices regardless of billing model. However, the Bulk Billing Incentive (BBI) is only available for bulk billed services to eligible patient groups.
The Workforce Incentive Program (WIP) payments are also available regardless of billing model but may be influenced by your patient demographics and service mix. When modelling your practice financials, include all applicable incentive programs to get an accurate picture of total revenue under each billing scenario.
