Our organization provides adult substance abuse and mental health services. We provide residential, PHP and IOP services. We would like to bill for the professional psychotherapy sessions that our pyschiatrist and internal medicine visits that our internal medicine physician providers provide. There have been ongoing discussions regarding the appropriate Place of Service code when a patient is receiving PHP and IOP services. Our facilities are free-standing, independently owned behavioral health care facilities. Our Coding Manager believes we should use POS 52; however, some believe this is intended for a hospital based facility. I would like to know your thoughts on the appropriate POS for the E&M codes. Thanks.
