Relating the diagnosis code to the SOAP note and recreating the billing statement.

If the chart has been signed off you will need to delete the CPT/HCPCS code from the Billing Statement and then post to billing. Add the deleted code along with the diagnosis to the New Charges tab and then post to patient account.

If this doesn't resolve the issue and you are still getting the error, please submit a support ticket and a member of our support team will reach out to assist you as soon as possible.
