At our Residential Treatment Center we have a psychiatrist that is contracted with us and does monthly visits to our patients. He bills us and then we bill the patient to pay us. Since his service is not part of the daily rate of the RTC can he bill it as Office/Outpatient or does he have to bill it as Inpatient since he See's the patients in the RTC? The only inpatient we can find is hopsital or PHP the 99221, 222, 223 codes but it does not define RTC.
My question is should we be billing it as Office or Other 99201, 202, 203 with place of service 56 (RTC) on CMS for professional?
Or billing it with the inpatient codes?
(The patient pays us and we provide them with a courtesy claim that they can submit to their insurance for possible reimbursement. We have a it clearly in our contract also and are OON with all insurance carriers.)
