Official Description

Proctectomy, partial, with anastomosis; abdominal and transsacral approach

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 45114 refers to a partial proctectomy performed using both abdominal and transsacral approaches. A proctectomy is a surgical operation that involves the removal of part of the rectum, which is the final section of the large intestine leading to the anus. The term "partial" indicates that only a portion of the rectum is excised rather than the entire structure. The transsacral approach, although rarely utilized, involves accessing the rectum through an incision made in the lower back, specifically at the midline, which allows for direct visualization and manipulation of the rectal area. This approach is complemented by an abdominal incision, which facilitates access to the proximal segment of the rectum and potentially the sigmoid colon. The procedure is typically indicated for conditions affecting the rectum, such as tumors or severe inflammatory diseases, where removal of the affected segment is necessary to restore health and function. The surgical technique requires careful planning and execution to ensure proper anastomosis, which is the reconnection of the remaining segments of the rectum and colon after the diseased portion has been removed.

1. Indications

The procedure described by CPT® Code 45114 is indicated for specific conditions affecting the rectum that necessitate surgical intervention. These indications may include:

  • Rectal Tumors The presence of malignant or benign tumors within the rectum that require partial removal to prevent further complications or progression of disease.
  • Severe Inflammatory Diseases Conditions such as ulcerative colitis or Crohn's disease that result in significant damage to the rectal tissue, necessitating surgical resection.
  • Rectal Injuries Traumatic injuries to the rectum that may compromise its integrity and function, requiring surgical repair and resection of the affected area.

2. Procedure

The procedure for CPT® Code 45114 involves several detailed steps, combining both transsacral and abdominal approaches to achieve the desired surgical outcome. The following steps outline the process:

  • Step 1: Patient Positioning The patient is positioned prone in a jack-knife position to facilitate access to the rectum through the transsacral approach. This positioning is crucial for the subsequent incision and exposure of the surgical site.
  • Step 2: Transsacral Incision An incision is made at the midline of the back, starting approximately 2 cm proximal to the anal verge and extending upwards about 8-10 cm. This incision allows access to the lower sacral region.
  • Step 3: Resection of Coccyx and Sacral Segments The coccyx is excised, and the two lower sacral segments are resected to provide adequate exposure of the distal segment of the rectum, which is essential for the subsequent steps of the procedure.
  • Step 4: Mobilization and Division of the Rectum The rectum is mobilized and divided distally, allowing for the removal of the affected segment. This step is critical to ensure that the diseased portion is completely excised.
  • Step 5: Closure of Transsacral Incision After the rectum has been addressed, the incision made in the back is closed, ensuring that the surgical site is properly secured.
  • Step 6: Abdominal Incision The patient is then repositioned to a supine position, and a midline incision is made in the abdomen. This incision allows for exploration of the abdominal cavity and access to the proximal rectum.
  • Step 7: Identification of Proximal Transection Site The proximal transection site is identified, which may include the sigmoid colon. This step is essential for determining the extent of the resection needed.
  • Step 8: Mobilization and Division of Sigmoid Colon or Rectum The sigmoid colon and proximal rectum are mobilized, and the sigmoid colon or rectum is divided above the diseased segment, preparing for anastomosis.
  • Step 9: Anastomosis The remaining proximal and distal segments are anastomosed in an end-to-end fashion, ensuring continuity of the gastrointestinal tract after the diseased portion has been removed.
  • Step 10: Placement of Drains and Closure Drains are placed as necessary to prevent fluid accumulation, and the abdominal incision is then closed, completing the surgical procedure.

3. Post-Procedure

Post-procedure care following a partial proctectomy with anastomosis involves monitoring the patient for any complications, such as infection or anastomotic leakage. Patients may require pain management and should be observed for signs of bowel function returning. Recovery may involve dietary modifications and gradual reintroduction of normal activities as tolerated. Follow-up appointments are essential to assess healing and ensure that the anastomosis is functioning properly. Additional considerations may include the need for further interventions or therapies depending on the underlying condition that necessitated the surgery.

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).
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.
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
