About the Australian Medicare Card
Medicare is Australia's universal healthcare system administered by Services Australia. It provides access to free hospital care, subsidized doctor visits (Medicare Benefits Schedule), and reduced-cost prescription medications (PBS).
The 10-digit number identifies the family card account, while an Individual Reference Number (IRN) on the side identifies individual family members listed on the card.
Medicare Check Digit Calculation Algorithm
The 9th digit is derived from the first 8 digits using weighted Modulo 10 addition:
Sum = Σ (dᵢ × Wᵢ) for i from 1 to 8; Check Digit = Sum mod 10
- Extract the first 8 digits of the Medicare account number.
- Multiply each digit by its corresponding positional weight [1, 3, 7, 9, 1, 3, 7, 9].
- Sum all 8 products together.
- The 9th check digit is the remainder of the total sum divided by 10.
- The 10th digit designates the card issue sequence.
