Updating or changing a claim

You can update a claim if you need to change the initial diagnosis or add a new one. You can also fix small errors in a claim form after you’ve submitted it.

    Fix a small error in a claim form

    If you submit an ACC45 for your patient and notice a small error in the information you submitted, you can send us a correction. Examples of errors you can fix:

    • incorrect spelling of the patient’s name
    • giving the wrong side of the body for the injury
    • a typo in the read code or date of the accident.

    To fix the error, call or email our registration team. If you’ve sent us a paper version of the ACC45 and we haven’t received this yet, you can email us a copy of the form.

    Adding a diagnosis to a claim

    While treating your patient, you may find another injury. If it relates to the first injury we cover and caused by the same accident, you can request to add the new diagnosis to the patient’s claim.

    Eg, you’re treating a shoulder injury from a fall and later find the patient injured their knee in the same fall.

    Changing a diagnosis

    We’ll look at your request to change a diagnosis if:

    • there’s been an admin error, eg a claim showed the injury was on the wrong part of the body
    • the initial diagnosis of the injury was wrong.

    How to add or change a diagnosis

    If you’re a general or nurse practitioner you can:

    • fill in the ACC18 through your practice management system or our online system
    • call or email our registration team. Your patient may need another assessment if it’s a complex injury.

    If you’re an Allied health provider, submit an ACC32 prior approval request. First check to see if it is a standard or non-standard request:

    Submit standard and non-standard prior approval requests 

    If you’re updating a sensitive claim, tell your patient to contact us. We'll talk them through the process. They may need another assessment.

    Information you need to provide

    Give us the following information:

    • the date the original injury happened
    • the original injury diagnosis
    • a description of how the new or extra injury occurred
    • where on the body the new injury is
    • Read code for the new or extra diagnosis
    • a description of the link between the original and new or extra injury
    • medical evidence, eg clinical notes, reports, correspondence, x-rays, to support your request.

    After you make a request to change or add a diagnosis by form

    We’ll let you know our decision within three working days. There may be a delay if we need a clinical advisor to assess your request, or we need more information. We’ll let you know if this happens.

    When we’ve made our decision we’ll write to you and your patient.
