Official Description

Sphincterotomy, anal, division of sphincter (separate procedure)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 46080 refers to a sphincterotomy of the anal region, specifically the division of the anal sphincter as a separate procedure. The anal sphincters consist of two main components: the internal and external anal sphincters, which are circular muscles that encircle the anus. Their primary function is to maintain closure of the anal opening, allowing for the storage of stool in the rectum until it is appropriate to defecate. The internal anal sphincter operates involuntarily, meaning it is not consciously controlled, while the external sphincter is under voluntary control. In cases where the resting pressure of the internal sphincter is excessively high, it may lead to spasms, which can hinder the healing process of anal fissures—painful tears in the mucous membrane of the anus. The sphincterotomy procedure involves making a lateral incision in the internal anal sphincter to relieve muscle tension. This incision does not completely sever the muscle ring but rather divides the muscle tissue sufficiently to alleviate spasms, thereby facilitating easier passage of stool and promoting the healing of fissures.

1. Indications

The sphincterotomy procedure is indicated for specific conditions related to the anal sphincter and anal fissures. The following are the primary indications for performing this procedure:

  • Anal Fissures - Painful cracks in the mucous membrane of the anus that can cause significant discomfort and may not heal properly due to high resting pressure in the internal anal sphincter.
  • Chronic Anal Fissures - Fissures that persist over time and do not respond to conservative treatments, necessitating surgical intervention to relieve symptoms and promote healing.
  • Increased Internal Sphincter Pressure - Conditions where the internal anal sphincter exhibits excessive resting pressure, leading to spasms that can exacerbate pain and hinder healing.

2. Procedure

The sphincterotomy procedure involves several key steps to ensure effective division of the anal sphincter muscle. The following outlines the procedural steps:

  • Step 1: Anesthesia Administration - The procedure typically begins with the administration of local or general anesthesia to ensure the patient is comfortable and pain-free during the surgery.
  • Step 2: Positioning - The patient is positioned appropriately, usually in a lithotomy or prone position, to provide optimal access to the anal region for the surgeon.
  • Step 3: Surgical Incision - A lateral incision is made in the internal anal sphincter. This incision is carefully executed to divide the muscle tissue without completely severing the entire muscle ring, which helps to maintain some degree of sphincter function.
  • Step 4: Muscle Division - The surgeon gently divides the muscle fibers of the internal anal sphincter, which helps to relieve the tension and spasms that contribute to the pain associated with anal fissures.
  • Step 5: Hemostasis - After the division of the sphincter, the surgeon ensures that any bleeding is controlled and that hemostasis is achieved before closing the incision site.
  • Step 6: Closure - The incision may be closed with sutures or left to heal naturally, depending on the surgeon's preference and the specific circumstances of the procedure.

3. Post-Procedure

Following the sphincterotomy, patients are typically monitored for any immediate complications. Post-procedure care may include pain management, instructions for wound care, and dietary recommendations to facilitate bowel movements. Patients are often advised to avoid straining during bowel movements and may be prescribed stool softeners to ease the passage of stool. Recovery time can vary, but many patients experience significant relief from symptoms and improved healing of anal fissures within a few weeks following the procedure. Follow-up appointments are usually scheduled to assess healing and address any concerns that may arise during the recovery process.

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.
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.)
