If a patient is present for a filling but decides he does not want to accomplish the planned procedure and would like to address the fact that the patient needs a complete upper denture. The treatment plan was already completed which includes the complete upper denture. The patient is given a referral to an outside prosthodontist and X-Rays were taken. The patient has Medicaid dental and only X-Rays can not be charged out per Medicaid rules. Is there another appropriate code that can be used in conjunction with the X-Rays that describes a limited exam and referral given?
