Official Description

Excision aural glomus tumor; extended (extratemporal)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 69554 involves the excision of an aural glomus tumor through an extended extratemporal approach. Aural glomus tumors are benign neoplasms that originate from paraganglionic cells located in glomus tissue, which is situated near the temporal bone. These tumors can be categorized into two main types: glomus jugulare tumors, which arise from the adventitia of the dome of the jugular bulb, and glomus tympanicum tumors, which develop from glomus bodies along the tympanic branch of the glossopharyngeal nerve. The choice of surgical approach for excising these tumors is determined by their size and location. For smaller tumors confined to the middle ear, a transcanal approach (CPT® Code 69550) is utilized, where the external auditory canal is accessed and enlarged to expose the tumor. In cases where the tumor has extended into the mastoid bone, a transmastoid approach (CPT® Code 69552) is employed, involving an incision behind the ear to access and clear the mastoid cells of tumor tissue. However, when the tumor has invaded the temporal bone, as in the case of CPT® Code 69554, a more extensive surgical intervention is required. This involves a C-shaped incision that begins above the ear and extends around the ear and down the neck, allowing for the elevation of a flap to expose critical structures such as the temporal muscle, mastoid bone, and neck anatomy. The procedure aims to achieve complete removal of the tumor while preserving hearing whenever possible, although it may necessitate sacrificing the external auditory canal and middle ear structures depending on the tumor's precise location.

1. Indications

The excision of an aural glomus tumor using CPT® Code 69554 is indicated for patients presenting with the following conditions:

  • Aural Glomus Tumor - The presence of a benign tumor arising from paraganglionic cells in glomus tissue near the temporal bone, which may cause symptoms such as hearing loss, tinnitus, or other auditory disturbances.
  • Invasion of Temporal Bone - Tumors that have extended beyond the middle ear and into the temporal bone, necessitating a more extensive surgical approach for complete excision.
  • Failure of Conservative Management - Cases where non-surgical management has not been effective in alleviating symptoms or controlling tumor growth.

2. Procedure

The procedure for excising an aural glomus tumor using CPT® Code 69554 involves several critical steps:

  • Incision - A C-shaped incision is made starting above the ear, extending in a wide arc around the ear and down the neck. This incision provides access to the underlying structures necessary for tumor removal.
  • Flap Elevation - A flap is elevated to expose the temporal muscle, mastoid bone, and neck structures. This step is crucial for gaining adequate visibility and access to the tumor.
  • Mastoidectomy - A complete mastoidectomy is performed, which includes the removal of the mastoid tip. This allows for thorough access to the tumor and surrounding tissues.
  • Bone Excision - The inferior tympanic bone is excised, and the external auditory canal is skeletonized to facilitate the removal of the tumor.
  • Vascular Exposure - The internal carotid artery is exposed and protected during the procedure, ensuring that critical vascular structures are safeguarded.
  • Jugular Vein Management - The internal jugular vein is exposed and ligated as part of the surgical process to manage blood flow and reduce the risk of complications.
  • Nerve Protection - The facial nerve is identified and protected throughout the procedure to prevent any potential nerve damage.
  • Tumor Dissection and Removal - The tumor is carefully dissected from surrounding structures and removed. The surgical team aims to preserve hearing whenever possible, although it may be necessary to sacrifice the external auditory canal and middle ear structures depending on the tumor's location.

3. Post-Procedure

Post-procedure care following the excision of an aural glomus tumor using CPT® Code 69554 includes monitoring for complications such as bleeding, infection, and neurological deficits. Patients may require pain management and should be advised on activity restrictions to promote healing. Follow-up appointments are essential to assess recovery, monitor for any recurrence of the tumor, and evaluate hearing function. Rehabilitation services, including audiology consultations, may be necessary to address any hearing loss resulting from the procedure.

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.
