Z858 – Epilation by cryopexy
OHIP Psychiatric Code — OCULAR AND AURAL SURGICAL PROCEDURES · Schedule of Benefits
This surgical procedure involves the removal of eyelashes (epilation) using a freezing technique (cryopexy). The service has 6 base units for anaesthesia (). Refer to the 'Skin and Subcutaneous Tissue - Integumentary System' or 'Lid Tumours or Unlisted Plastic Procedures' sections for procedures related to verruca, keratosis, etc. ().
When to Use
- Use Z858 specifically for the treatment of trichiasis or distichiasis where cryopexy is the chosen modality for eyelash epilation.
- Use this code when the clinical objective is the destruction of the hair follicle via freezing to prevent recurrent ingrown eyelashes, rather than simple mechanical removal.
Common Pitfalls
- Do not bill Z858 for the removal of eyelid lesions such as verruca or keratosis; these must be billed under the appropriate Integumentary System or Lid Tumours sections.
- Avoid billing Z858 in conjunction with Z857 (Epilation by electrolysis) for the same eyelid, as this may be flagged as duplicate or overlapping service intent.
Billing Tips
- Ensure the procedure note explicitly mentions the use of cryopexy, as this distinguishes the service from standard epilation and justifies the specific code selection.
