Can anyone give me suggestions for coding and billing this scenario. My patient has a procedure done in the office every month code 53855 (urethral stent change) . The physician performed a different procedure for another diagnosis/reason in the hospital as an outpatient (22) on this patient. At the same time she also performed the monthly procedure he usually has because he was due. However on the day of the procedure the hospital informed her they did not have the device (stent) available, so the provider took a device from the office stock. We are a private practice and are not owned or affiliated with the hospital other than surgical privileges. Payer reimbursement is based on code and site of service so how can I bill this and get reimbursed to cover and recoup the money we paid for the device we supplied. The payer Medicare will reimburse us at the facility par rate, so can anyone tell me how to bill for a device that should have been provided by the hospital?
