Z857 – Epilation by hyfrecator, electrolysis or cryopexy
OHIP Psychiatric Code — OCULAR SURGICAL PROCEDURES · Schedule of Benefits
Epilation by hyfrecator or electrolysis is a procedure for the removal of eyelashes. It is listed as a surgical procedure under the 'Eyelids' subsection. The fee is for the surgeon (suffix A). Anaesthesia services (suffix C) are eligible for payment with 6 basic units plus time units. Assistant services (suffix B) are not listed with basic units but may be payable on an Independent Consideration (IC) basis by submitting a claim with M400B if required (see ). The Schedule notes that for conditions such as 'Verruca, keratosis, etc.' one should refer to the 'Skin and Subcutaneous Tissue - Integumentary System' section or 'Lid Tumours or Unlisted Plastic Procedures' ().
When to Use
- Use Z857 specifically for the permanent removal of misdirected or ingrown eyelashes (trichiasis or distichiasis) via hyfrecator or electrolysis.
- Use this code for eyelid-specific epilation rather than Z858, which is reserved for the removal of lesions or other non-epilation procedures.
Common Pitfalls
- Billing Z857 for the removal of skin tags, verruca, or keratosis on the eyelid will result in rejection; these must be billed under the Integumentary System section.
- Attempting to bill Z857 alongside a general office visit code (A007) is generally disallowed as the procedure fee is intended to be comprehensive for the surgical encounter.
Billing Tips
- Ensure the clinical note explicitly documents the use of hyfrecator or electrolysis to justify the use of Z857 over other minor surgical codes.
