Official Description

Excision exostosis(es), external auditory canal

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 69140 involves the excision of exostosis(es) from the external auditory canal (EAC). Exostoses are bony growths that develop within the EAC, leading to a gradual narrowing of the canal due to the deposition of bone on the canal walls. This condition can result in various auditory issues, including hearing loss or discomfort. During the procedure, the physician first conducts an otoscopic examination to identify the exostoses present in the EAC. Following this examination, an operating head is attached to the otoscope, allowing for the introduction of surgical instruments through the speculum. The surgical site is then cleansed with a disinfectant to minimize the risk of infection. A medially based canal skin flap is created and reflected towards the tympanic membrane, providing access to the bony growths. The exostoses are meticulously removed using specialized tools such as bone curettes and diamond burrs. After the excision, the previously created skin flap is repositioned to cover the surgical site, and the area is closed to promote healing. This procedure is distinct from CPT® Code 69145, which pertains to the removal of soft tissue lesions in the EAC, highlighting the specific focus on bony abnormalities in this coding description.

1. Indications

The excision of exostosis(es) from the external auditory canal is indicated for patients presenting with the following conditions:

  • Exostoses of the External Auditory Canal These bony growths can lead to narrowing of the canal, potentially causing hearing loss or discomfort.
  • Auditory Symptoms Patients may experience symptoms such as hearing impairment, a sensation of fullness in the ear, or recurrent ear infections due to the obstruction caused by the exostoses.
  • Physical Examination Findings An otoscopic examination may reveal visible bony growths within the EAC, necessitating surgical intervention for removal.

2. Procedure

The procedure for excising exostosis(es) from the external auditory canal involves several critical steps:

  • Step 1: Otoscopic Examination The physician begins by performing an otoscopic examination of the external auditory canal to identify the presence and extent of the exostoses. This examination is crucial for planning the surgical approach.
  • Step 2: Preparation After identifying the exostoses, the physician attaches an operating head to the otoscope, allowing for enhanced visualization and access. Surgical instruments are then passed through the speculum to prepare for the excision.
  • Step 3: Site Cleansing The surgical site is cleansed with a disinfectant solution to reduce the risk of postoperative infection, ensuring a sterile environment for the procedure.
  • Step 4: Creation of Skin Flap A medially based canal skin flap is developed and carefully reflected onto the tympanic membrane. This step is essential for accessing the bony growths without damaging surrounding structures.
  • Step 5: Excision of Exostoses The exostoses are then meticulously drilled away using specialized instruments such as bone curettes and diamond burrs. This step requires precision to ensure complete removal of the bony growths while preserving the integrity of the canal.
  • Step 6: Closure After the excision is complete, the previously created skin flap is repositioned to cover the surgical site. The area is then closed to facilitate healing and restore the normal anatomy of the external auditory canal.

3. Post-Procedure

Post-procedure care following the excision of exostosis(es) from the external auditory canal typically includes monitoring for any signs of infection, managing pain, and ensuring proper healing of the surgical site. Patients may be advised to avoid water exposure in the ear canal and to follow up with their physician for any necessary evaluations. The recovery process may vary depending on the extent of the excision and individual patient factors, but generally, patients can expect gradual improvement in symptoms as healing progresses.

22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
50 Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d).
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
62 Two surgeons: when 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associated add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons. each surgeon should report the co-surgery once using the same procedure code. if additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. note: if a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate.
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
