Summary & Overview
CPT 69421: Myringotomy with Middle Ear Aspiration and Eustachian Tube Inflation
CPT code 69421 covers myringotomy with possible aspiration of middle ear fluid and/or inflation of the eustachian tube via a tube or catheter placed through the tympanotomy. This brief surgical procedure is used to treat eustachian tube dysfunction and otitis media and is commonly performed in ambulatory surgical centers, hospital operating rooms, or procedure rooms in otolaryngology practices. Nationally, accurate coding for this service matters for appropriate procedural reporting, device utilization tracking, and aggregation of otologic surgical volumes.
Key payers included in the analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical intent and typical settings for the procedure, plus operational context relevant to billing and reporting. The publication summarizes benchmarks and reimbursement context where available, highlights common coding considerations, and outlines clinical circumstances associated with using this code. Data not available in the input is identified explicitly where applicable.
The content is intended for revenue cycle staff, otolaryngology clinicians, and policy analysts seeking a clear, national-level reference for CPT code 69421 and what it represents in clinical and billing workflows.
Billing Code Overview
CPT code 69421 describes a myringotomy with possible aspiration and/or eustachian tube inflation. The procedure involves an incision in the tympanic membrane (eardrum) to allow drainage or to permit passage of air; the provider may aspirate fluid from the middle ear and/or introduce air through a tube or catheter placed through the tympanotomy to inflate the eustachian tube to treat eustachian tube dysfunction or otitis media.
Service type: Surgical/ENT procedure (myringotomy with middle ear aspiration and/or eustachian tube inflation)
Typical site of service: Ambulatory surgical center or hospital operating room; may also be performed in an otolaryngology clinic or procedure room depending on setting and patient needs.
Clinical & Coding Specifications
Clinical Context
A 4-year-old child presents to the ambulatory surgery center with recurrent otitis media with effusion and persistent conductive hearing loss despite a course of antibiotics and observation. The patient has symptoms of ear fullness and delayed speech concerns reported by parents. Otoscopy demonstrates a bulging, non-mobile tympanic membrane with serous effusion on pneumatic otoscopy and tympanometry consistent with middle ear fluid (type B). After preoperative evaluation and informed consent, the patient undergoes general anesthesia. The surgeon performs a myringotomy with placement of a ventilation tube or performs myringotomy with aspiration of middle ear fluid; insufflation of the Eustachian tube may be attempted via catheter as indicated. Intraoperative documentation includes laterality, size/type of tympanostomy tube if placed, whether suctioning/aspiration was performed, and any complications. Postoperative workflow includes recovery in PACU, discharge instructions for ototopical drops if indicated, scheduled audiology follow-up, and monitoring for tube extrusion or persistent effusion.
