Question: Answer: Caution: It's never correct to use a "personal history of" code instead of a "family history of" code just in hopes of getting paid. "Personal history" means that the patient has a history of a certain condition (such as category V12, Personal history of certain other diseases). These V codes are also great codes and often very important to the encounter -- but, as noted, some payers don't generally reimburse for V codes if they are the first code listed. Also note that some personal history codes (such as V14.0, Personal history of allergy to medicinal agents; penicillin) are secondary diagnosis codes only.
