Excision of rectal tumor by proctotomy, transsacral or transcoccygeal approach

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 45160 refers to the surgical procedure involving the excision of a rectal tumor through a proctotomy, utilizing either a transsacral or transcoccygeal approach. This procedure is indicated when a tumor is present in the rectal area, necessitating surgical intervention for removal. The approach begins with an incision made along the midline of the back, starting approximately 2 cm above the anal verge and extending upwards for about 8 to 10 cm. This incision allows access to the rectum by excising the coccyx and resecting the lower sacral segments as required for adequate exposure. Once the rectum is accessible, an incision is made directly at the tumor site, enabling the surgeon to excise the tumor along with a margin of healthy tissue to ensure complete removal. To confirm that the excised margins are clear of cancerous cells, frozen sections are obtained during the procedure. The excised specimen is then sent to a laboratory for pathological evaluation, which is also separately reportable. After the tumor removal, the rectum is repaired with sutures, and the initial incision is closed, completing the procedure. This method is distinct from other excision techniques, such as those described in CPT® Codes 45171 and 45172, which utilize a transanal approach for tumor removal.

1. Indications

The procedure described by CPT® Code 45160 is indicated for the removal of rectal tumors that may pose a risk to the patient's health. The specific indications for this procedure include:

  • Rectal Tumor Presence: The primary indication for this procedure is the presence of a tumor in the rectum that requires surgical excision.
  • Malignancy Concerns: The procedure may be indicated when there is a suspicion or confirmation of malignancy, necessitating the removal of the tumor along with surrounding healthy tissue to ensure clear margins.
  • Symptomatic Tumors: Patients experiencing symptoms related to rectal tumors, such as bleeding, obstruction, or pain, may also be candidates for this surgical intervention.

2. Procedure

The procedure for excising a rectal tumor via CPT® Code 45160 involves several critical steps, which are detailed as follows:

  • Step 1: Incision Creation The surgeon begins by making a midline incision on the back, starting approximately 2 cm proximal to the anal verge and extending upwards for about 8 to 10 cm. This incision provides access to the underlying structures necessary for the procedure.
  • Step 2: Coccyx and Sacral Resection Following the incision, the coccyx is excised, and the two lower sacral segments may be resected as needed. This step is crucial for gaining adequate exposure of the rectum to facilitate the tumor removal.
  • Step 3: Rectal Incision Once the rectum is accessible, the surgeon incises the rectum at the site of the tumor or mass. This incision allows for direct access to the tumor for excision.
  • Step 4: Tumor Excision The tumor is excised along with a margin of healthy tissue surrounding it. This margin is essential to ensure that all cancerous cells are removed and to minimize the risk of recurrence.
  • Step 5: Frozen Section Analysis During the procedure, frozen sections are obtained from the excised tissue to confirm that the margins are clear of malignancy. This step is critical for ensuring the completeness of the excision.
  • Step 6: Pathological Evaluation The excised specimen is sent to the laboratory for pathological evaluation, which is separately reportable. This evaluation helps in determining the nature of the tumor and the adequacy of the excision.
  • Step 7: Rectal Repair After the tumor has been successfully excised, the rectum is repaired using sutures to restore its integrity.
  • Step 8: Closure of Incision Finally, the transsacral or transcoccygeal incision is closed, completing the surgical procedure.

3. Post-Procedure

Post-procedure care following the excision of a rectal tumor via CPT® Code 45160 typically involves monitoring the patient for any complications related to the surgery. Patients may experience pain at the incision site, which can be managed with appropriate analgesics. It is essential to monitor for signs of infection, such as increased redness, swelling, or discharge from the incision site. Additionally, patients may require follow-up appointments to assess healing and to discuss the results of the pathological evaluation of the excised tumor. Depending on the findings, further treatment or surveillance may be necessary. Patients are usually advised on dietary modifications and bowel care to promote recovery and prevent complications during the healing process.

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.
