From 1 July 2021, there are changes to the Closing the Gap (CTG) PBS Co-payment Program.

PBS prescribers will no longer be legally required to write or electronically print ‘CTG’ on eligible PBS prescriptions for registered Aboriginal and Torres Strait Islander people. Instead, when a claim is made PBS Online will verify the CTG status of the patient in real-time.

If the script has been claimed as CTG, i.e. a CTG value was entered in CTG field on the dispense form, the patient is registered for the program and the script is eligible to be claimed as CTG, the claim will be processed and the PBS response will be Accepted.

If the script has not been claimed as CTG, but the patient is registered for the program and the script is eligible to be claimed as CTG, the claim will be rejected and will need to be resubmitted. In this case, the PBS response will be Rejected.

New PBS Online reason codes have been added to support the enhancement to the Closing the Gap (CTG) PBS Co-payment Program. Please refer to the below table for an explanation of each new reason code.
