CPT4 code

Name of the Procedure:

Excision of 1 or More Lesions of Small or Large Intestine Not Requiring Anastomosis, Exteriorization, or Fistulization; Single Enterotomy


This surgical procedure involves removing one or more abnormal growths (lesions) from the small or large intestine through a single incision in the intestinal wall. It does not involve reconnecting sections of the intestine, bringing parts of the intestine outside the body, or creating a new opening in the intestine.


The procedure is aimed at removing abnormal tissues such as tumors, polyps, or other lesions from the intestine. The goals include preventing the spread of disease, alleviating symptoms, and improving digestive tract health.


  • Presence of small or large intestinal tumors or polyps.
  • Diagnosed intestinal lesions that may be benign or malignant.
  • Symptoms such as bleeding, obstruction, or other gastrointestinal issues.
  • Failed or inadequate response to non-surgical treatments.


  • Patients may need to undergo fasting for a specified period before the procedure.
  • Diagnostic tests such as blood work, imaging studies, or a colonoscopy may be required to assess the lesion.
  • Medication adjustments, particularly blood thinners, may be necessary.
  • A bowel preparation to clean out the intestines may be prescribed.

Procedure Description

  1. The patient is administered anesthesia to ensure comfort.
  2. A single enterotomy (incision in the intestine) is made to access the lesion.
  3. The surgeon identifies and excises the lesion from the intestinal wall.
  4. The incision is then closed securely.
  5. The intestinal function is checked to ensure there is no leakage or other issues.

Tools and equipment used include surgical instruments such as scalpels, forceps, and sutures. Anesthesia is administered to eliminate pain and discomfort during the procedure.


The procedure typically takes between 1 to 3 hours, depending on the number and size of the lesions.


This procedure is performed in a hospital or surgical center equipped for gastrointestinal surgeries.


  • A gastrointestinal surgeon performs the procedure.
  • An anesthesiologist administers and monitors anesthesia.
  • Surgical nurses and assistants aid in the operation.

Risks and Complications

  • Infection at the incision site or within the abdomen.
  • Bleeding or perforation of the intestine.
  • Adverse reactions to anesthesia.
  • Intestinal leakage at the resection site.
  • Postoperative bowel obstruction.


  • Removal of harmful or potentially cancerous lesions.
  • Relief of symptoms caused by the lesions.
  • Prevention of further complications or spread of disease.
  • Improvement in digestive health.


  • Patients may need to stay in the hospital for a few days post-surgery.
  • Instructions will include medications for pain management and antibiotics to prevent infection.
  • Patients are advised to gradually resume eating, starting with a liquid diet.
  • Normal activities can typically be resumed in a few weeks, but heavy lifting and strenuous activities should be avoided.


  • Non-surgical treatments such as medications or lifestyle changes.
  • Endoscopic removal of lesions, if applicable.
  • Watchful waiting with regular monitoring for small, non-symptomatic lesions.

Patient Experience

  • Patients will be under anesthesia during the procedure and will not feel pain.
  • Postoperative discomfort, managed with pain medication.
  • Gradual return to normal diet and activities, with specific instructions for care at home.
  • Follow-up appointments to monitor recovery and ensure no complications.
