Z845 – Removal of three or more embedded foreign bodies
OHIP Psychiatric Code — OCULAR SURGICAL PROCEDURES · Schedule of Benefits
Removal of three or more embedded foreign bodies from the cornea, performed under local anaesthetic. This service is listed as Independent Consideration (IC). Per , claims for IC services must be submitted with a supporting letter explaining the amount of the fee claimed, and must include an appropriate operative or consultation report, and a comparison of the scope and difficulty of the procedure in relation to non-IC procedures in the Schedule. This procedure is distinguished from Z847 (one foreign body) and Z848 (two foreign bodies). If a general anaesthetic is required, see Z852. This is a surgical procedure and is eligible for age-based premiums for patients under 16 (), after-hours procedure premiums (E409, E410) if non-elective (), and the trauma premium (E420) if criteria are met ().
When to Use
- Use Z845 when you remove three or more distinct embedded foreign bodies from the cornea during a single session, as opposed to Z847 for one or Z848 for two.
- Use Z845 for complex cases involving multiple metallic or organic foreign bodies requiring individual removal techniques under local anaesthetic.
Common Pitfalls
- Failing to submit the required supporting letter and operative report for IC claims will result in immediate rejection or payment at a default minimal rate.
- Attempting to bill Z845 when only one or two foreign bodies are removed, which should be billed under Z847 or Z848 respectively, will trigger an audit risk for upcoding.
- Neglecting to explicitly document the number of foreign bodies removed in the operative note, which is essential to justify the IC fee request over standard fixed-fee codes.
Billing Tips
- When drafting your IC letter, explicitly compare the time and technical complexity of removing three or more bodies against the fixed-fee structure of Z847 to justify your requested amount.
- Ensure the operative report clearly maps the location and depth of each foreign body to substantiate the 'embedded' nature of the procedure.
