What 69105 covers
An otolaryngologist typically performs this biopsy when tissue from a lesion in the external auditory canal is needed for diagnosis, such as evaluation of a growth or abnormal area in the ear canal. The canal extends inward from the ear opening toward the tympanic membrane; a biopsy of the visible outer ear instead is a different service. The procedure may be performed in an office or facility, depending on the lesion and clinical circumstances.
Choose this code when the service is tissue sampling for diagnosis, rather than definitive removal of the canal lesion. Document the canal site, the abnormal finding, the reason for sampling, and the specimen obtained. A separately performed pathology interpretation may be reported by the responsible pathologist. This is a 0-day global procedure, so same-day preoperative and postoperative care is included. For bilateral reporting with modifier 50, CMS pays 150%. When multiple procedures occur in one session, the highest-valued is paid in full and others at 50%. Assistant-at-surgery payment is restricted; co-surgeons and team surgery are not permitted.
