Suture of the rectum due to trauma, performed via an external approach. As a surgical procedure, this service includes all constituent and common elements as defined in the Schedule of Benefits. This fee is for the surgeon's service (suffix A). Separate fees are applicable for a surgical assistant (suffix B) and an anaesthetist (suffix C). The assistant fee is based on 6 base units plus time units. The anaesthetist fee is based on 7 base units plus time units. The procedure is eligible for various premiums including those for after-hours services, specific patient age groups, and trauma.

When to Use

Use S229 for the primary repair of a traumatic rectal laceration or perforation when the approach is external (e.g., perineal or trans-sacral).
Select this code when the procedure is performed as a distinct surgical event for trauma, rather than as part of a more extensive resection or abdominal procedure.

Common Pitfalls

Billing S229 in conjunction with other abdominal surgical codes without ensuring the procedures are not considered 'included' or 'incidental' under the Schedule of General Preamble rules.
Failing to document the specific Injury Severity Score (ISS) when attempting to claim the E420 trauma premium, which leads to automatic rejection of the premium.

Billing Tips

Always verify if the procedure qualifies for E409 or E410 after-hours premiums based on the exact start time, as these are mutually exclusive with other special visit premiums.
Ensure the surgical assistant (S229B) and anaesthetist (S229C) fees are calculated using the correct base units (6 and 7 respectively) plus time units, as these are not flat-fee additions.
