System description
Two sets of records are sent for matching. These are extracted from the Enrolment Registers sent to MoH by Public Health Organisations (PHOs) to claim payments.

One set comprises records from particular providers, subcontracted to a PHO. The records are selected to enable a review of the capitation funding provided to those practices ('Schedule 1').

The second set comprises randomly selected entries from across all PHO Enrolment Registers ('Schedule 2').

MoH send the selected records to INZ to be matched. INZ returns any relevant immigration information. MoH then filters the matched records according to various eligibility criteria. Further action is only taken when people are identified as ineligible.

Although the direct relationship is between the PHO and the patients, to simplify the process for the PHOs under investigation, MoH sends letters to people who appear to be ineligible for the public funding to give them the opportunity to provide evidence of eligibility. This constitutes notice of adverse action under section 103.

If the patient is not able to provide evidence of eligibility, MoH advises the PHO and requests that it remove the ineligible person from the Enrolment Register and make no further claim for capitation payment for that person.
