2025 CPT code 44145

Partial colectomy with coloproctostomy (low pelvic anastomosis).

Refer to CPT guidelines for proper coding.

Modifiers may be applicable; refer to current CPT guidelines for specific scenarios.

Medical necessity is established by the underlying condition requiring surgical intervention. This may include cancer, diverticulitis, strictures causing obstruction, or other clinically significant conditions affecting the colon.

The surgeon performs the procedure, ensuring proper prepping, anesthesia, incision, colon mobilization, resection, coloproctostomy, hemostasis, and closure.

IMPORTANT (For laparoscopic procedure, use 44207)

In simple words: This surgery removes part of the colon and reattaches it to the rectum. The surgeon makes a cut to access the colon, takes out the bad section, and connects the healthy parts back together.

The procedure involves removing a portion of the colon and connecting the remaining end to the rectum to restore digestive continuity.This may include mobilization of the splenic flexure. The procedure starts with an incision to access the target area of the colon. Then the surgeon mobilizes and removes the diseased section. The remaining colon is connected to the rectum (coloproctostomy), and finally, the incision is closed.

Example 1: A patient with a cancerous tumor in the sigmoid colon requires a partial colectomy and coloproctostomy to remove the tumor and restore bowel continuity., A patient with severe diverticulitis affecting a segment of the descending colon undergoes this procedure to remove the diseased section., A patient experiencing intestinal blockage due to a stricture in the colon requires a partial colectomy with coloproctostomy to alleviate the obstruction.

Documentation should include operative notes detailing the extent of the colectomy, location of anastomosis, any complications, and confirmation of the diagnosis necessitating the procedure (e.g., cancer, diverticulitis).
