Clinical & Coding Specifications
Clinical Context
A typical patient is an adult referred to otolaryngology or oral-maxillofacial surgery for evaluation of chronic eustachian tube dysfunction and recurrent otitis media with effusion unresponsive to medical therapy. The patient reports persistent aural fullness, hearing difficulty, and intermittent otorrhea despite nasal steroid spray and multiple courses of antibiotics. Physical exam shows middle ear effusion and reduced tympanic membrane mobility. After discussion of risks and benefits, the patient is scheduled for placement of tympanostomy tubes under monitored anesthesia care or brief general anesthesia in an ambulatory surgical center. The clinical workflow includes preoperative assessment (history, otoscopic exam, audiometry), informed consent, intraoperative myringotomy with bilateral tympanostomy tube insertion, postoperative observation, and discharge instructions with follow-up for tube check and audiogram scheduling. Typical site of service is an ambulatory surgery center or outpatient ENT clinic procedure room with anesthesia capability.
