Summary & Overview
CPT 69145: Excision of Lesion, External Auditory Canal
CPT code 69145 designates surgical excision of a localized lesion in the external auditory canal (for example, sebaceous cyst, lipoma, or cholesteatoma) performed to obtain a diagnosis and alleviate pain or hearing difficulty. This code is used across outpatient surgical settings and is relevant to otolaryngologists, surgical centers, and payers managing head and neck procedural claims. Nationally, accurate coding for 69145 matters for appropriate clinical documentation, claim adjudication, and tracking of otologic surgical volumes.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context—when the procedure is indicated and typical care settings—alongside payer coverage considerations and commonly reported modifiers. The publication summarizes typical billing practices and related service-line implications for ambulatory surgical centers and hospital outpatient departments.

Clinical & Coding Specifications
Clinical Context
A 47-year-old patient presents to the otolaryngology clinic with progressive unilateral ear fullness, intermittent otorrhea, and decreased hearing. On otoscopic exam there is a palpable, well-circumscribed subepithelial mass in the external auditory canal consistent with a suspected cholesteatoma or epidermal inclusion cyst. Audiometry confirms a mild conductive hearing loss on the affected side. The clinician schedules a procedure to resect the lesion from the external auditory canal under local anesthesia with monitored sedation in an ambulatory surgical center. The intraoperative goals are complete excision of the diseased tissue to relieve obstruction and permit histopathologic diagnosis, obtain hemostasis, and inspect the canal and tympanic membrane for additional disease. Specimens are submitted for pathology. Postoperative workflow includes immediate recovery, discharge with analgesia and wound-care instructions, and a short-term follow-up visit to confirm healing and review pathology results.
