Patient (ICD-9 code 758.39) is being treated at hospital outpaitent daily by an OT for feeding therapy (Vital Stim). Another OT will be starting Occupational therapy in the patients home using CPT codes 97003, 97112, 97110, 97530. We are concerned that ins. carrier might deny since patient is already having another type of OT. Should a modifier be used? What is CPT code for Vital Stim therapy? If same CPT codes are not used, will that be enough to not be denied?
