Official Description

Radical excision external auditory canal lesion; without neck dissection

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 69150 involves a radical excision of a lesion located in the external auditory canal. This surgical intervention is necessary when a lesion has begun to invade surrounding tissues, necessitating a comprehensive removal to ensure complete excision. The procedure is performed with careful attention to the facial nerve, which is critical for preserving facial function. An incision is typically made in the external auditory canal, extending towards the front of the ear and into the parotid gland area. The excision includes not only the lesion itself but also a margin of healthy tissue to ensure that any potential cancerous cells are removed. In some cases, a post-auricular incision may be utilized to facilitate the removal of the tumor at its base, which may involve the canal wall, external ear cartilage, and any other affected tissues. During the surgery, intraoperative frozen sections of the surgical margins are sent for pathological examination to confirm that all cancerous cells have been excised. If any margins are found to be positive for tumor invasion, additional piecemeal resection is performed until all visible and microscopic evidence of the tumor is eliminated. The procedure may also involve the removal of skin, soft tissue, cartilage, and bone as necessary. It is important to note that if reconstruction of the external auditory canal is required, this may be reported separately using appropriate codes, such as skin grafts. CPT® Code 69150 is specifically used when the radical excision is performed without a radical neck dissection, which is a more extensive procedure that involves the removal of lymph nodes and surrounding structures.

1. Indications

The radical excision of an external auditory canal lesion, as described by CPT® Code 69150, is indicated for the following conditions:

  • External Auditory Canal Lesion - The procedure is performed to remove lesions that have begun to invade adjacent structures within the external auditory canal.
  • Suspected Malignancy - Indications may include lesions that are suspected to be malignant, requiring comprehensive excision to prevent further spread.
  • Persistent or Recurrent Lesions - Lesions that have recurred after previous treatments may necessitate radical excision to ensure complete removal.

2. Procedure

The procedure for radical excision of an external auditory canal lesion involves several critical steps:

  • Step 1: Incision - The surgeon begins by making an incision in the external auditory canal, which extends towards the front of the ear and into the parotid gland area. This incision allows access to the lesion and surrounding tissues.
  • Step 2: Excision of the Lesion - The anterior portion of the external auditory canal lesion is excised, along with a margin of surrounding healthy tissue. This is crucial to ensure that any potential cancerous cells are removed.
  • Step 3: Additional Incisions - A post-auricular incision may be made to facilitate the removal of the tumor at its base. This incision helps in excising the canal wall, external ear cartilage, and any other affected tissues.
  • Step 4: Pathological Examination - Intraoperative frozen sections of the surgical margins are sent for pathological examination to assess whether any cancerous cells remain. This step is vital for determining the completeness of the excision.
  • Step 5: Resection of Positive Margins - If the pathological examination reveals positive margins for tumor invasion, the surgeon performs piecemeal resection of any gross tumor extension until all margins are confirmed free of visible and microscopic evidence of tumor.
  • Step 6: Removal of Additional Tissues - The procedure may involve the removal of skin, soft tissue, cartilage, and bone as necessary to ensure complete excision of the lesion.

3. Post-Procedure

After the radical excision procedure, patients may require specific post-operative care to promote healing and monitor for any complications. This may include pain management, wound care, and follow-up appointments to assess recovery. The physician will provide instructions on how to care for the surgical site and may schedule additional imaging or examinations to ensure that the lesion has been completely removed and to monitor for any signs of recurrence. If reconstruction of the external auditory canal is necessary, this will be addressed in subsequent procedures, which may involve the use of skin grafts or other reconstructive techniques.

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.
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).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
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.
76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
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.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).
