S193 – Revision of standard ileostomy into continent ileostomy pouch
OHIP Urology Code — DIGESTIVE SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
S193 is a surgical procedure for the revision of a standard ileostomy into a continent ileostomy pouch. The fee for the surgeon is for the procedure itself, while fees for the assistant (S193B) and anaesthetist (S193C) are calculated based on basic units plus time units. - Surgeon (A Suffix): Performs the procedure. - Assistant (B Suffix): Assists at surgery. The fee is calculated from 6 basic units plus time-based units. - Anaesthetist (C Suffix): Administers anaesthesia. The fee is calculated from 7 basic units plus time-based units. This procedure is listed under the Digestive System surgical section. General rules for surgical procedures, including billing for multiple procedures and after-hours premiums, apply.
When to Use
- Use S193 specifically for the conversion of a pre-existing standard ileostomy into a continent ileostomy pouch (e.g., Kock pouch).
- Do not use this code for initial ileostomy creation; use the appropriate S180-series codes for primary stoma formation.
Common Pitfalls
- Billing S193 alongside E718 is prohibited; the system will reject the claim due to the explicit restriction between these codes.
- Failure to document the specific conversion nature of the procedure can lead to audit scrutiny, as the distinction between a revision and a primary construction is critical for the fee schedule.
Billing Tips
- Ensure that if an assistant (S193B) or anaesthetist (S193C) is present, their claims are submitted with the corresponding suffix to trigger the correct basic unit calculation.
