Any experiences with having past diagnostic codes on insurance claims changed due to a misdiagnosis?

If my son had seen a counselor who initially diagnosed with one condition, but later recognized that this was a misdiagnosis, would the counselor be able to retroactively change the diagnostic codes associated with the previous insurance claims to corrected ones?

For example, let's say a provider were to change the diagnosis to something that is NOT covered by a patient's insurance. The provider could resubmit all previous claims that have the incorrect diagnostic code with the updated, correct diagnostic code. The provider would be required to pay a clawback to the insurance company for these past claims, since the updated diagnoses are not covered by the patient's policy. Then, the provider would charge the client their out-of-pocket rate for all the previous sessions.

Would this remove any and all insurance records of the misdiagnosis? Additionally, has anyone seen this happen successfully?

Thanks for your help!
