If the patient has previously had a course of orthodontic treatment, it's possible for them to have a further course providing they meet the Index of Orthodontic Treatment Needed (IOTN) criteria.
If the patient meets the IOTN criteria, you must contact your Commissioner to confirm they're willing to fund a second course of orthodontic treatment for the patient.
You do not need to tell us if your Commissioner agrees to fund a further course of orthodontic treatment. We'll process the claim as normal if the previous Course of Treatment (CoT) was closed.
