Amy, I have an Arkansas Medicaid inpatient claim that is denying CPT 90870 which was billed with 99231/90792 on different dates of services spanning 3/6/14-3/21/14. Arkansas Medicaid is stating that we need to review the TOS and or lack of modifier billed. They stated that the claim will pay in a professional or technical location. Would you mind clarifying that please?I was under the impression that this was in a hospital facility. You are correct. If he is in outpatient facility and coding for the physician performing they will only code the CPT code. However, if hospital facility they will code both the CPT and the ICD-9-PX. I was just giving them advice on both facility locations as I did not know which they were in
