I am billing for a Pediatric clinic for PT, OT and ST. Does anyone know what codes are timed codes and which ones are not, or is it based on what insurance they have. I know for Medicaid they are all timed in 15 min. time frames and 30 mins for eval. But for insurance I know at least speech therapy they are not time based for at least BCBS. I am not sure about PT & ST. Please help. Thanks.
