S183 represents a surgical procedure for cecopexy or sigmoidopexy. This involves surgically securing either the cecum or the sigmoid colon to the abdominal wall to prevent torsion or volvulus. According to the listing in the Schedule of Benefits, this service is only payable as a standalone procedure and not in conjunction with other major intra-abdominal surgeries during the same operative session.

When to Use

Use S183 as the primary procedure code when performing an isolated cecopexy or sigmoidopexy to prevent recurrent volvulus in a patient who is not undergoing a concurrent bowel resection.
Use this code for elective fixation procedures where the clinical objective is strictly the stabilization of the cecum or sigmoid colon to the abdominal wall.

Common Pitfalls

Billing S183 in combination with any other intra-abdominal surgical procedure will result in a claim rejection, as it is strictly defined as a standalone procedure.
Attempting to bill S183 alongside a bowel resection or other major digestive surgery is a common audit trigger; these procedures must be billed under their respective comprehensive codes rather than attempting to unbundle the fixation component.

Billing Tips

Ensure the operative report explicitly details the fixation technique to support the use of S183 as the sole procedure performed during the session.
If the procedure is performed after hours or on weekends, ensure the appropriate E-series procedure premium is applied to the S183 fee, as it qualifies as a non-elective surgical procedure.
