MPRCs are independent statutory committees established on a case by case basis to make independent determinations of whether a practitioner, or where relevant a person, should maintain the right to participate in Medicare, in the following circumstances: where a practitioner has been convicted of relevant criminal offences; where a practitioner has been found to have engaged in inappropriate practice on two separate occasions under the Professional Services Review (PSR) Scheme; where a practitioner or pathology company is reasonably believed to have breached a pathology undertaking; or where a practitioner or person is reasonably believed to have engaged in prohibited diagnostic imaging practices.
