This identifier profile defines a Medicare card number in an Australian context. A Medicare card is provided to individuals who are enrolled in [Medicare](https://www.servicesaustralia.gov.au/individuals/medicare). This definition supports sending either the 10 digit Medicare card number or the 11 digit number (includes the individual reference number (IRN)). 

### Usage Notes

The 10 digit format is supported as some systems do not support the 11 digit Medicare card number.

The 10 digit Medicare card number is not sufficient to uniquely identify the number associated with an individual on a Medicare card as a card may include up to 9 individuals. If required, profiles can constrain this profile further to restrict usage to 11 digits only as desired.

Medicare card numbers are not used for uniquely identifying patients, they are identifying information that can be used in conjunction with other elements such as name and date of birth appropriately to confirm identity.

**Usages:**
