Official Description

Limited pharyngectomy

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 42890 refers to a limited pharyngectomy, which is a surgical intervention primarily aimed at addressing malignant tumors located in the pharynx. However, it is important to note that this procedure can also be indicated for the removal of benign lesions or strictures that may obstruct normal pharyngeal function. During the operation, a horizontal incision is strategically made in the neck, specifically over the thyrohyoid membrane, to provide access to the pharyngeal area. The surgical approach involves the separation of the suprahyoid muscles from the hyoid bone laterally, allowing for better visualization and access to the pharynx. The valleculae, which are the spaces located at the base of the tongue, are entered, and the pharynx is exposed by retracting the larynx downwards and the tongue upwards. This careful manipulation enables the surgeon to identify the specific region of the pharynx that requires resection. If a lesion is present, it is excised along with a margin of healthy tissue to ensure complete removal and minimize the risk of recurrence. Following the excision, the surgical defect created in the pharynx is typically closed using sutures. In some cases, a separately reportable reconstruction may be necessary, which could involve the use of flaps or grafts to restore the integrity of the pharyngeal structure.

1. Indications

The limited pharyngectomy procedure, as described by CPT® Code 42890, is indicated for specific conditions affecting the pharynx. The following are the primary indications for performing this surgical intervention:

  • Malignant Tumors This procedure is typically performed for the excision of malignant tumors located in the pharynx, which may pose a threat to the patient's health and require surgical intervention for removal.
  • Benign Lesions In addition to malignant tumors, limited pharyngectomy may also be indicated for the removal of benign lesions that could cause obstruction or other complications within the pharyngeal area.
  • Strictures The procedure may be performed to address strictures in the pharynx, which can impede normal swallowing and breathing functions, thereby necessitating surgical correction.

2. Procedure

The limited pharyngectomy involves several critical procedural steps that ensure effective access and removal of the targeted pharyngeal tissue. The following outlines the key steps involved in the procedure:

  • Step 1: Incision A horizontal incision is made in the neck over the thyrohyoid membrane. This incision is strategically placed to provide optimal access to the pharyngeal region while minimizing damage to surrounding structures.
  • Step 2: Muscle Separation The suprahyoid muscles are carefully separated from the hyoid bone laterally. This step is crucial as it allows for better exposure of the pharynx and facilitates the subsequent steps of the procedure.
  • Step 3: Accessing the Pharynx The surgeon enters the valleculae, which are the spaces at the base of the tongue, and exposes the pharynx by retracting the larynx inferiorly and the tongue superiorly. This maneuver provides a clear view of the area that requires resection.
  • Step 4: Resection The specific region of the pharynx that is to be resected is identified. If a lesion is present, it is excised along with a margin of healthy tissue to ensure complete removal and reduce the risk of recurrence.
  • Step 5: Closure After the excision, the surgical defect in the pharynx is closed using sutures. In some cases, if the defect is significant, a separately reportable reconstruction may be performed using flaps or grafts to restore the pharyngeal structure.

3. Post-Procedure

Post-procedure care following a limited pharyngectomy is essential for ensuring proper recovery and minimizing complications. Patients may require monitoring for any signs of infection or complications related to the surgical site. Additionally, they may need to follow specific dietary modifications to accommodate the healing process of the pharynx. Pain management strategies will be implemented to ensure patient comfort during recovery. Follow-up appointments will be necessary to assess healing and to monitor for any potential recurrence of lesions or tumors. The healthcare team will provide guidance on any further treatments or interventions that may be required based on the pathology results from the excised tissue.

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).
GC This service has been performed in part by a resident under the direction of a teaching physician
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.
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
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.
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.
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.)
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).
