Z127 – Three or more lesions
OHIP Psychiatric Code — INTEGUMENTARY SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
Surgical excision of three or more lesions, such as cysts, haemangiomas, or lipomas, from areas other than the face or neck. This procedure is performed under local anaesthetic and falls under the Integumentary System Surgical Procedures, specifically Group 3 for skin and subcutaneous tissue lesions.
When to Use
- Use Z127 when excising three or more distinct lesions (e.g., lipomas or cysts) from the trunk or extremities in a single operative session.
- Choose Z127 instead of individual excision codes like Z125 or Z126 when the total count of lesions removed from non-facial/neck areas reaches the threshold of three.
Common Pitfalls
- Billing Z127 in combination with individual excision codes for the same anatomical site will trigger a rejection for duplicate billing or unbundling.
- Attempting to claim Z127 for lesions located on the face or neck is a common audit trigger, as those areas require different surgical codes (e.g., Z128 or Z129 series).
Billing Tips
- Always append the E542 premium if the procedure is performed in a clinic setting rather than a hospital to capture the additional fee.
- Ensure the operative note explicitly lists the anatomical location and type for at least three lesions to justify the use of this specific code over lower-tier excision codes.
