Z191 – Repair of laceration, more than 15.1 cm, other than face
OHIP Psychiatric Code — INTEGUMENTARY SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
This service is for the surgical repair of a laceration greater than 15.1 cm in length, located on an area other than the face. This fee is for a standard closure. For complex lacerations requiring more time or specific anatomical alignment, see Z187 or Z188. Note: As per , wound closure via tissue adhesives (such as cyanoacrylate) is payable at 50% of the listed fee.
When to Use
- Use Z191 for a standard, linear laceration repair exceeding 15.1 cm on the trunk or extremities where no complex anatomical reconstruction or layered closure is required.
- Choose Z191 over Z187 or Z188 when the repair is straightforward and does not involve the specialized tissue alignment or complex surgical techniques defined for those codes.
Common Pitfalls
- Billing Z191 for facial lacerations, which must be billed under the appropriate facial repair codes regardless of length.
- Failing to reduce the fee by 50% when using tissue adhesives (e.g., Dermabond), as mandated by M14, which leads to automatic audit adjustments.
- Overlooking the requirement to document the Injury Severity Score (ISS) when attempting to claim the E420 trauma premium alongside this code.
Billing Tips
- If performing the procedure in a community office setting, ensure E542 is appended to capture the additional $11.55 facility premium.
