Z855 – Drainage of abscess - general anaesthetic
OHIP Psychiatric Code — OCULAR SURGICAL PROCEDURES · Schedule of Benefits
Drainage of an abscess of the eyelid when rendered under general anaesthetic. The '#' prefix indicates that when performed in a hospital or an Integrated Community Health Services Centre (ICHSC), the costs for premises, equipment, supplies, and personnel are funded through the institution and cannot be billed to the patient, as per page .
When to Use
- Use Z855 when performing a formal incision and drainage of a significant eyelid abscess that requires the patient to be under general anaesthesia, rather than local infiltration.
- Select Z855 for complex eyelid abscesses requiring surgical facility resources that cannot be managed in an office setting using local anaesthetic codes like 0200A.
Common Pitfalls
- Billing Z855 for procedures performed under local anaesthesia or sedation; this code strictly requires general anaesthesia documentation.
- Attempting to bill for facility or tray fees alongside Z855, which is prohibited as the '#' prefix indicates these costs are already covered by the hospital or ICHSC.
Billing Tips
- If the patient meets ASA III criteria and an anaesthesiologist is involved, ensure E022C is appended to the claim to capture the additional units for severe systemic disease.
