Y853
Y853 – Y853
OHIP Other Code · Schedule of Benefits
When to Use
- Use Y853 as a mandatory administrative code when billing for the completion of a 'Certificate of Examination' under the Mental Health Act.
- Apply this code in conjunction with K007 or other applicable assessment codes when the physician performs the formal psychiatric evaluation required for an involuntary admission.
Common Pitfalls
- Failing to link Y853 to the corresponding assessment fee code results in an automatic rejection, as Y853 is a non-fee service code that requires a primary service code to process.
- Billing Y853 for informal or voluntary assessments where no formal Certificate of Examination was legally executed is a common audit trigger for inappropriate billing.
Billing Tips
- Always ensure the date of service for Y853 matches the date of the formal documentation of the Certificate of Examination to avoid reconciliation errors during OHIP audits.
