S274 – Deceased donor, liver removal
OHIP Urology Code — DIGESTIVE SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
This code covers the surgical procedure of removing a liver from a deceased donor. This service is a component of liver transplantation procedures and the fee is for the surgeon's service. Separate calculations apply for anaesthesia (suffix C) and surgical assistant (suffix B) services based on basic and time units. This service is eligible for various after-hours, age-related, and special premiums. As per , a second assistant's service is eligible for payment without requiring special authorization.
When to Use
- Use S274 specifically for the surgical removal of a liver from a deceased donor as part of a multi-organ procurement or liver transplantation protocol.
- Use this code for the primary surgeon's fee; do not use it for the recipient's transplant procedure, which is billed under distinct codes such as S294 or S295.
Common Pitfalls
- Failing to bill the second assistant (suffix B) correctly; unlike most procedures, S274 allows for a second assistant without prior authorization, but it must be explicitly claimed.
- Incorrectly applying after-hours premiums (E409/E410) to the total claim rather than the procedural fee, or failing to ensure the case commencement time meets the specific threshold for the premium.
Billing Tips
- Ensure that surgical assistant (suffix B) and anaesthesiologist (suffix C) services are billed with their respective basic units (6 and 8 units) to avoid underpayment.
- When claiming trauma premiums (E420), ensure the Injury Severity Score (ISS) is clearly documented in the patient's record, as this is a mandatory audit requirement for the 50% increase.
