Summary & Overview
CPT 0953T: Revision or Replacement of Active Middle Ear Implant
CPT code 0953T covers surgical revision or replacement of a totally implantable active middle ear implant (AMEI). This code represents care for patients with implanted AMEIs who require operative intervention to revise or replace the internal implant component; the procedure explicitly excludes mastoidectomy and replacement of the external sound processor. Nationwide, procedures addressing implanted hearing devices are clinically significant due to rising utilization of implantable hearing technology and the need for device maintenance, troubleshooting, and corrective surgery.
Key payers in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise description of the procedure and typical settings of care, plus an outline of what to expect in a national benchmarking and policy discussion: coverage patterns, reimbursement benchmarks where available, and the clinical context surrounding implant revision and replacement. The publication also summarizes common billing modifiers and service line considerations relevant to surgical implant work, while noting when specific payer policy details or diagnosis coding are not provided. Intended for billing managers, surgical administrators, and clinical leaders, the piece frames CPT code 0953T within operational and payer contexts relevant to implantable middle ear device management.
Billing Code Overview
CPT code 0953T describes a surgical procedure to revise or replace a totally implantable active middle ear hearing implant (AMEI). The description specifies that this service focuses on revising or replacing the implanted device itself and explicitly excludes performing a mastoidectomy or replacing the external sound processor.
Service Type: Surgical revision or replacement of a totally implantable active middle ear implant.
Typical Site of Service: Operative setting—commonly performed in an ambulatory surgery center or hospital outpatient surgical suite when management of an implanted AMEI requires device revision or replacement.

Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with a previously implanted totally implantable active middle ear implant (AMEI) presents with progressive device malfunction characterized by decreased hearing performance despite intact external sound processor components. The patient has persistent conductive-sensorineural mixed hearing loss for which the AMEI was originally placed. Preoperative evaluation includes audiometry, device interrogation, and imaging (CT temporal bones) to assess implant position and exclude mastoid pathology. After multidisciplinary discussion between otology and audiology, the decision is made to surgically revise or replace the totally implantable AMEI. In the operating room, the surgeon exposes the implant pocket and internal electrode/transducer, assesses fixation and component integrity, and performs partial or complete device removal with replacement of the implant or revision of anchoring and connections as indicated. This procedure explicitly excludes a mastoidectomy and does not involve replacing the external sound processor. Postoperative workflow includes device function testing, wound care, and audiology follow-up for programming and rehabilitation.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased Procedural Services | Use when work required to revise or replace the AMEI is substantially greater than typical due to complexity, extensive scarring, or unexpected intraoperative findings. |
