CPT 69806: Endolymphatic Sac Decompression with Shunt Placement

CPT code 69806 represents endolymphatic sac decompression with placement of a shunt to drain and relieve inner-ear endolymphatic pressure. Nationally, this surgical procedure is relevant for otolaryngology practices managing patients with refractory endolymphatic hydrops or Meniere-related symptoms when conservative measures have not provided adequate control. The code captures both the decompression and shunt placement as a single operative service.

Key payers considered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication summarizes payer coverage patterns, national benchmarks for utilization and allowed amounts where available, and relevant clinical context for coding and claim submission.

Readers will find: an explanation of the clinical intent and typical settings for the procedure; guidance on common billing scenarios and associated modifiers (listed elsewhere); and a summary of payer coverage behavior and reimbursement benchmarks if available. Data not available in the input is noted where applicable. This overview is written for a national audience of clinicians, coders, and policy analysts assessing the role and billing implications of endolymphatic sac decompression with shunt placement.

Clinical & Coding Specifications

Clinical Context

A typical patient is an adult in their 30s–60s presenting with progressive, unilateral sensorineural hearing loss, episodic vertigo, tinnitus, and aural fullness consistent with Meniere disease unresponsive to medical therapy (dietary sodium restriction, diuretics, intratympanic steroid or gentamicin). After diagnostic confirmation with audiometry and vestibular testing and failure of conservative measures, an otologic surgeon schedules an operative endolymphatic sac decompression with endolymphatic shunt placement (69806). The patient is admitted for same-day surgery at an ambulatory surgery center or hospital outpatient surgical unit under general anesthesia. The operative workflow includes preoperative evaluation, surgical exposure via a postauricular incision, mastoidectomy to identify the endolymphatic sac, creation of a drainage opening, placement of a small shunt or drain into the sac to provide continuous pressure relief, hemostasis, wound closure, and postoperative recovery with audiologic and vestibular follow-up visits. Typical documentation includes operative report describing the sac exposure and shunt placement, anesthesia record, pre- and postoperative audiograms, informed consent, and discharge instructions addressing activity, wound care, and signs of complications (CSF leak, infection, hearing loss).

Coding Specifications

Modifier	Description	When to Use
`00`	Default/No modifier	Use when no other modifier applies and no specific payer modifier is required
`22`	Increased procedural services	Use when documented work or complexity substantially exceeds typical for `69806`
`23`	Unusual anesthesia	Use when general anesthesia is not planned but the procedure requires unusual anesthesia due to patient condition
`26`	Professional component	Use when reporting only the surgeon’s professional component separate from technical facility charges (rare for this intraoperative procedure)
`50`	Bilateral procedure	Use when bilateral endolymphatic sac procedures are performed and payer accepts bilateral modifier for this CPT
`51`	Multiple procedures	Use when `69806` is performed with additional unrelated surgical procedures in the same session (list additive codes)
`52`	Reduced services	Use when portion of the procedure is intentionally not completed or is reduced/documented as partial
`53`	Discontinued procedure	Use when the procedure is started but terminated for patient-related or clinical reasons before completion
`62`	Two surgeons	Use when two surgeons with distinct specialties work together on the same surgical session and documentation supports co-surgeon billing
`80`	Assistant surgeon	Use when a qualified assistant surgeon participates and payer requires modifier for assistant billing
`81`	Minimum assistant surgeon	Use when a lesser role assistant participates and documentation supports minimal assistant work
`82`	Assistant not available	Use when a qualified resident is unavailable and a non‑surgeon assistant provides assistance per payer rules
`76`	Repeat procedure by same physician	Use when the exact procedure `69806` is repeated later (same physician) during the same postoperative period
`RT`	Right side	Use to indicate the procedure was performed on the right ear when laterality is required by payer
`LT`	Left side	Use to indicate the procedure was performed on the left ear when laterality is required by payer
