Summary & Overview
CPT 69320: External Auditory Canal Reconstruction
CPT code 69320 represents surgical creation of an external auditory canal to correct congenital absence of the ear canal, a reconstructive procedure aimed at restoring anatomic auditory pathway and addressing associated hearing impairment. This procedure is clinically significant for pediatric and otologic surgical practices and has implications for hearing outcomes, surgical planning, and coverage determinations nationwide. Key payers relevant to national coverage and reimbursement discussions include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will find a concise reference to the clinical intent of the code, typical sites of service, and the service type. The publication summarizes how payers approach coverage, common billing modifiers and documentation themes, and the clinical context that justifies medical necessity for reconstructive canaloplasty or canal reconstruction. It also highlights benchmarks and policy considerations affecting authorization and coding practices for ear canal reconstruction. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 69320 describes a surgical procedure to create an external auditory canal to correct congenital absence of the ear canal, a condition that can cause hearing impairment. The procedure involves reconstructive surgery of the external ear canal to restore a patent auditory pathway.

Clinical & Coding Specifications
Clinical Context
A 6-year-old child with congenital aural atresia presents with unilateral conductive hearing loss and failed newborn hearing screening. Preoperative evaluation includes audiometry, CT temporal bone to assess middle ear and mastoid anatomy, and otologic consultation. The surgical plan is creation of an external auditory canal (canalplasty/atresiaplasty) to establish a patent canal, often combined with tympanoplasty or ossicular reconstruction depending on middle ear status. The procedure is typically performed in an ambulatory surgery center or hospital operating room under general anesthesia. Preoperative documentation includes indication (congenital absence of external auditory canal), informed consent, imaging review, and baseline audiogram. Intraoperative documentation records laterality, technique used to create the canal, graft or skin flap details, whether tympanoplasty or ossicular work was performed, estimated blood loss, complications, and specimens if applicable. Postoperative care instructions include wound care, activity restrictions, audiology follow-up, and timing for CT or audiogram reassessment. Typical payer interactions involve preauthorization with commercial payors such as Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, BUCA, and Medicare for adults when applicable.
