Q. Why Can't 12 Diagnosis Codes be Billed for One Procedure?
A. According to 5010 HIPAA Standards for Professional Claims, a claim can have 12 diagnosis codes, but a service line or a procedure code can only have four diagnosis codes. In order for a claim to have 12 diagnosis codes, at least three procedure codes must be listed with four different diagnosis codes.
