I recently received a denial from Medicare of CO-170 (payment is denied when performed/billed by this type of provider) for the above CPT code and my provider was our PA (physician assistant). This was for monitoring PT/INR on a patient taking warfarin. Can anyone give me a reference/billing guideline as to when this type of provider was excluded from providing this service.
Thnx.
