CPT 69310: External Ear Canal Reconstruction for Stenosis
CPT code 69310 represents surgical reconstruction of the external ear canal to correct acquired stenosis. This otologic procedure addresses canal narrowing that can impair hearing, drainage, and local health; it is performed by otolaryngologists or neurotologists in operative settings. Nationally, coding for canaloplasty and related reconstructive ear procedures matters for accurate procedural capture, surgical quality measurement, and appropriate facility and professional reimbursement.
Key payers commonly involved in coverage decisions include Aetna, Blue Cross Blue Shield, Cigna, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical intent and typical settings for CPT code 69310, plus what to expect in payer coverage patterns and documentation needs. The analysis covers typical benchmarks for utilization and payment, common clinical indications that justify the procedure, and policy considerations affecting prior authorization and medical necessity determinations.
This publication equips coding professionals, otolaryngology clinicians, and revenue cycle staff with the context needed to interpret claims, support clinical documentation, and navigate payer requirements for external ear canal reconstruction.

Billing Code Overview
CPT code 69310 describes a surgical reconstruction of the external ear canal performed to treat acquired stenosis (narrowing) of the canal. The procedure restores or enlarges the ear canal lumen to improve drainage, aeration, and hearing function when narrowing has occurred from disease, trauma, or prior surgery.
Service Type: Surgical, Otologic/ENT procedure
Typical Site of Service: Operative suite in a hospital or ambulatory surgery center
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult presenting to an otolaryngology clinic with progressive conductive hearing loss, recurrent cerumen impaction, chronic otitis externa, or recurrent ear canal infections after prior trauma or surgery. Examination reveals acquired stenosis of the external auditory canal with narrowing of the canal lumen, canal skin contracture, or bony canal deformity that impairs visualization of the tympanic membrane and limits cerumen clearance. Audiometry and otoscopy confirm canal compromise; CT temporal bone may be used if bony involvement or cholesteatoma is suspected.
The clinical workflow includes preoperative evaluation and counseling, medical optimization (treatment of active infection), and documentation of symptoms, exam findings, and diagnostic tests. On the day of service the patient undergoes surgical reconstruction of the external auditory canal under general or local anesthesia with microsurgical techniques to excise stenotic tissue, perform canalplasty or meatoplasty, and reconstruct canal lining with local skin flaps or grafts. Postoperative care includes ear packing or stents, pain control, topical antibiotic/steroid drops as indicated, scheduled follow-up for packing removal, wound checks, and audiometric reassessment. This procedure is typically performed in an ambulatory surgery center, hospital outpatient department, or operating room depending on anesthesia and comorbidities.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when work required is substantially greater than usual for 69310 (document increased complexity and time). |
23 | Unusual anesthesia | Use when general anesthesia is medically required for a minor procedure that would normally be done with local anesthesia. |
26 | Professional component | Use when billing only the professional (physician) component of a service that has a separate technical component. |
50 | Bilateral procedure | Use when 69310 is performed on both left and right external auditory canals (also consider reporting bilateral distinct procedure rules). |
51 | Multiple procedures | Use when 69310 is reported in the same operative session with other unrelated surgical procedures; payors may require reduced payment for secondary procedures. |
52 | Reduced services | Use when the procedure is partially reduced or not completed as originally planned (document reason). |
53 | Discontinued procedure | Use when the procedure is started but discontinued due to patient safety concerns. |
59 | Distinct procedural service | Use to indicate a separate and distinct service from other procedures performed in the same session (avoid overuse; support with operative note). |
62 | Two surgeons | Use when two surgeons work together as primary surgeons performing distinct portions of 69310 (document each surgeon’s portion). |
63 | Procedure performed on infants less than 4 kg | Use for eligible age/weight-based reporting when applicable. |
76 | Repeat procedure by same physician | Use when the same physician repeats the procedure later during the postoperative period (note: 76 is not in the supplied list; not included). |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
| 207Y00000X | Otolaryngology (ENT) | Primary specialty performing external auditory canal reconstruction. |
| 207K00000X | Otology/Neurotology | Subspecialty for complex canalplasty, cholesteatoma, or temporal bone involvement. |
| 208D00000X | Plastic and Reconstructive Surgery | Involvement when complex skin flap or graft reconstruction of canal or periauricular tissues is required. |
| 207L00000X | Facial Plastic Surgery | May assist for auricular or meatal reconstruction when cosmetic considerations are primary. |
| 208000000X | General Surgery | Rarely involved; included for broader surgical settings. |
Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |
|---|---|---|
H60.89 | Other otitis externa | Chronic or recurrent external otitis can lead to cicatricial stenosis of the canal requiring surgical reconstruction. |
H60.3 | Swimmer's ear | Recurrent external otitis from water exposure may result in chronic inflammation and eventual narrowing. |
H61.23 | Impacted cerumen, bilateral | Chronic impaction may be secondary to canal stenosis; evaluation and management often accompany reconstruction. |
H72.09 | Perforation of tympanic membrane, unspecified ear | Tympanic membrane status is assessed preoperatively; associated middle ear disease can influence surgical planning. |
M85.89 | Other specified disorders of bone density and structure | Bony canal deformities or exostoses contributing to stenosis may require canalplasty and reconstruction. |

69310 | Reconstruction of external auditory canal for acquired stenosis | Primary procedure for surgical correction of canal narrowing. |
69210 | Removal of impacted cerumen (simple) | Performed preoperatively or in clinic to clear canal when stenosis is partial; not a definitive treatment for stenosis. |
