CPT 69550: Excision of Aural Glomus Tumor via External Auditory Canal

CPT code 69550 represents surgical excision of an aural glomus tumor through an incision in the external auditory canal. This otologic procedure is clinically important because glomus tumors can cause pain, hearing disturbance, and local destruction; surgical removal is a common definitive treatment. Nationally, attention to correct coding and site-of-service designation affects billing, payer adjudication, and quality tracking for ear and skull-base procedures.

Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for 69550, common sites of service where the procedure is delivered, and the payer landscape relevant to reimbursement and claims processing. The publication summarizes available benchmarks and coverage considerations, highlights typical billing practices, and notes common modifiers used with this type of surgical service. It also outlines where data was not available in the input to guide readers on potential gaps.

This summary is intended for a national audience of clinicians, coding professionals, and policy analysts seeking a clear reference for CPT code 69550 and its clinical and billing implications.

Clinical & Coding Specifications

Clinical Context

A typical patient is an adult presenting to otolaryngology with progressive unilateral otalgia, pulsatile tinnitus, or conductive hearing loss. Examination reveals a vascular mass behind the tympanic membrane or within the external auditory canal consistent with an aural (glomus) tumor. Audiometry and imaging (CT or MRI) confirm a localized glomus lesion confined to the external auditory canal/tympanic region without extensive skull base invasion. The provider schedules a surgical excision via an incision in the external auditory canal under general anesthesia. Perioperative workflow includes preoperative history and physical, informed consent documenting risks (hearing change, facial nerve injury, bleeding), surgical site marking, anesthesia evaluation, intraoperative removal of the tumor through the canal incision, hemostasis, and placement of any packing or dressing. Postoperative care includes short observation, pain control, instructions for ear care, and follow-up for wound check and audiologic reassessment.

Coding Specifications

Modifier	Description	When to Use
`11`	Normally expected performance and/or outcome of the service	Use when the procedure is performed as planned without complications.
`22`	Increased procedural services	Use when work, time, or difficulty is substantially greater than typical for excision of an aural glomus tumor.
`23`	Unusual anesthesia	Use when general anesthesia is required for a procedure normally done with local/regional anesthesia due to patient factors.
`26`	Professional component	Use when billing only the physician's professional component separate from technical services (rare for this surgical CPT).
`50`	Bilateral procedure	Use when identical procedures are performed on both left and right ears (if clinically applicable).
`52`	Reduced services	Use when the procedure is partially reduced or not completed as originally planned.
`53`	Discontinued procedure	Use when the procedure is terminated due to extenuating circumstances after anesthesia induction.
`62`	Two surgeons	Use when two surgeons work together as primary surgeons performing distinct portions of the excision.
`66`	Surgical team	Use when a surgical team performs the procedure (e.g., highly complex resection requiring multiple specialists).
`76`	Repeat procedure by same physician	Use when the same surgeon repeats the procedure within the global period (if clinically necessary).
`77`	Repeat procedure by another physician	Use when a different surgeon repeats the procedure within the global period.
`80`	Assistant surgeon	Use when an assistant surgeon assists with the excision and is billed separately.
`81`	Minimum assistant surgeon	Use when a minimum assistant service is provided by another surgeon.
`82`	Assistant surgeon (when qualified resident unavailable)	Use when an assistant is required and a qualified resident is not available.
`TC`	Technical component	Use when billing only the technical component of the service (seldom applicable for surgeon billing).

Taxonomy Code	Specialty	Notes
207V00000X	Otolaryngology (ENT)	Primary specialty performing excision of aural glomus tumors.
2080P0226X	Otology & Neurotology	Subspecialists managing complex or skull-base–adjacent glomus tumors.
207VP0000X	Head and Neck Surgery	Surgeons involved when lesion extends toward skull base or requires multi-discipline planning.
207L00000X	General Surgery	May be involved in multidisciplinary cases, though uncommon for isolated external auditory canal lesions.

`H93.2`	Tinnitus, unspecified	Symptom commonly reported with vascular ear tumors; may be an indication for surgical intervention.
`H90.3`	Sensorineural hearing loss, bilateral	Hearing symptoms associated with ear tumors; audiologic findings guide management.
