Z122 – Cyst, haemangioma, lipoma - single lesion - face or neck - local anaesthetic
OHIP Psychiatric Code — INTEGUMENTARY SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
Excision of a single cyst, haemangioma, or lipoma from the face or neck, performed under local anaesthetic. This service includes all constituent and common elements of an insured surgical service as outlined in the Schedule of Benefits. As per the general preamble, for procedures with a 'Z' prefix, an admission assessment by a surgical specialist who has assessed the patient prior to admission for the same illness is deemed a specific re-assessment (, ).
When to Use
- Use Z122 for the excision of a single benign lesion such as a lipoma or cyst specifically located on the face or neck under local anaesthetic.
- Choose Z122 when the procedure is performed in an office or clinic setting, ensuring you add the E542 premium for services rendered outside of a hospital.
Common Pitfalls
- Do not bill an admission assessment or subsequent hospital visit on the same day as Z122, as the surgical fee is considered inclusive of these services per the general preamble.
- Avoid using Z122 for lesions on the trunk or extremities; these require different codes from the Z123-Z127 series.
- Claiming Z122 for multiple lesions is a common audit trigger; you must bill only one unit for a single lesion and use appropriate codes for additional excisions if performed.
Billing Tips
- Always append the E542 premium when performing this procedure in your office to capture the additional $12.65 fee.
- Ensure your operative report clearly documents the anatomical location (face or neck) and the nature of the lesion to justify the use of the Z-prefix code over general excision codes.
