CPT 69603: Revision Radical Mastoidectomy, Ossicle and Middle Ear Excision

CPT code 69603 represents a revision radical mastoidectomy: an operative procedure that converts a previous complete or modified radical mastoidectomy into a radical mastoidectomy by removing diseased middle ear structures and reconstructing the ear canal when indicated. This code captures complex otologic surgery performed for persistent or recurrent infections, cholesteatoma, tympanic membrane perforation, and ongoing conductive or mixed hearing loss after an initial mastoidectomy failed to achieve a dry ear. Nationally, accurate use of 69603 matters for clinical documentation, surgical quality measurement, and appropriate payment for high-complexity ear surgery.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the procedure, expected sites of service, typical service classification, and a summary of common billing modifiers associated with complex revision otologic surgery. The publication provides benchmarks and policy-relevant points for coding, claims review, and payer coverage considerations, as well as pointers to clinical indications driving use of this revision procedure. Data not available in the input are noted where applicable.

Billing Code Overview

CPT code 69603 describes a surgical revision in which the provider performs a radical mastoidectomy to revise a prior complete or modified radical mastoidectomy. The procedure includes excision of the ossicles, eustachian tube and middle ear mucosa, removal of granulation tissue and cholesteatoma, and reconstruction of the ear canal if needed. The revision is performed because the prior procedure failed to produce a dry ear, leading to recurrent otitis media with pus accumulation, tympanic membrane perforation, and recurrent or residual hearing loss.

Service type: Revision radical mastoidectomy surgery

Typical site of service: Hospital operating room or ambulatory surgical center, where otologic reconstructive surgery and mastoid revision procedures are performed.

Clinical & Coding Specifications

Clinical Context

A 52-year-old male with a history of a prior modified radical mastoidectomy presents with persistent otorrhea, recurrent otitis media, chronic eardrum perforation, and progressive conductive hearing loss despite prior surgery and prolonged medical therapy. Otologic exam and CT temporal bone demonstrate recurrent cholesteatoma and persistent mastoid cavity disease with granulation tissue and ongoing middle ear mucosal disease. The surgeon schedules a revision radical mastoidectomy to excise residual cholesteatoma and granulation tissue, remove remaining ossicles and diseased middle ear mucosa and eustachian tube, and reconstruct the external auditory canal as indicated to achieve a dry, stable ear.

Typical clinical workflow:

Preoperative evaluation: history and physical, audiogram, CT temporal bones, pre-op counseling, informed consent, anesthesia evaluation.
Procedure: general anesthesia, retroauricular approach, canal meatoplasty or canal wall down conversion if needed, excision of cholesteatoma and granulation tissue, removal of ossicles and diseased mucosa/eustachian tube, possible obliteration or reconstruction of the canal, hemostasis, packing and dressing.
Postoperative care: short-term analgesia and antibiotics per facility protocol, ear packing removal in clinic, serial surveillance for cavity epithelialization, audiology follow-up and consideration of rehabilitative options for persistent hearing loss.
Typical site of service: inpatient or ambulatory surgery center depending on patient comorbidities and extent of disease; commonly performed in an operating room with general anesthesia.

Coding Specifications

Modifier	Description	When to Use
`22`	Increased procedural services	Use when intraoperative complexity substantially exceeds typical for `69603` and documentation supports increased work.
`23`	Unusual anesthesia	Use when general anesthesia is medically contraindicated and significant anesthesia complexity is documented.
`26`	Professional component	Use if reporting only the surgeon’s professional component separate from technical facility billing (rare for operative CPT).
`50`	Bilateral procedure	Use if identical procedures are performed on both ears during the same operative session.
`51`	Multiple procedures	Use when `69603` is reported with additional distinct procedures during same operative session.
`52`	Reduced services	Use when procedure is intentionally partially reduced or not completed and documentation supports the reduction.
`53`	Discontinued procedure	Use when procedure is started but discontinued due to extenuating circumstances documented in the record.
`59`	Distinct procedural service	Use to indicate separate, distinct procedures not normally reported together when modifier `59` criteria are met.
`62`	Two surgeons	Use when two surgeons of different specialties perform distinct parts of the procedure and both report services.
`78`	Return to OR for related procedure during postoperative period	Use when a related procedure for a complication of `69603` is performed during the global period.
`79`	Unrelated procedure or service during postoperative period	Use when an unrelated procedure is performed during the global period (note: `79` is not in the provided list; do not use if absent).
`LT`	Left side	Use to indicate left ear procedure when laterality is required.
`RT`	Right side	Use to indicate right ear procedure when laterality is required.
