Patient enters the office for staple removal after c-section and physicians perform an incision and drainage on cellulitis of the abdominal wall by the incision. The physician than schedules patient for a more extensive Incision and Drainage with debridement of the wound in the OR at the hospital the following day. My question is can I bill out the I&D done in the office? I believe the return trip to the OR is billable. Any help would be appreciated. We did provide the global care for the patient.
