S314 – Peritoneal abscess - abdominal
OHIP Urology Code — DIGESTIVE SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
This procedure involves the surgical incision and drainage of an abscess located within the abdominal cavity (peritoneal abscess). This is an open surgical procedure listed under the Digestive System, Abdomen, Peritoneum and Omentum section.
When to Use
- Use S314 for the formal open surgical incision and drainage of a localized peritoneal abscess when no other definitive abdominal procedure is performed.
- Select S314 when performing an open exploration and drainage of an intra-abdominal abscess that is not associated with a primary organ resection or repair.
Common Pitfalls
- Attempting to bill S314 in addition to S310 or S315 will result in automatic rejection, as these are mutually exclusive open/laparoscopic abdominal procedures.
- Billing S314 for percutaneous drainage performed by interventional radiology is incorrect; this code is strictly for open surgical procedures.
Billing Tips
- Ensure the operative report clearly details the open nature of the procedure to justify S314 over less invasive codes or diagnostic laparoscopy codes.
- If the abscess drainage is performed as part of a larger, more complex abdominal surgery, you must bill the primary procedure code instead of S314, as the drainage is considered incidental.
