T668 – T668
OHIP Other Code · Schedule of Benefits
When to Use
- Use T668 for the initial assessment and management of a patient presenting with a confirmed or suspected acute poisoning or toxic ingestion.
- Apply this code when the clinical encounter requires immediate stabilization and toxicological evaluation, distinguishing it from a standard A007 or A008 consultation.
- Utilize T668 for complex cases involving multi-system toxicity where the time and intensity of care exceed the scope of a routine office visit.
Common Pitfalls
- Billing T668 in conjunction with a standard consultation code (A005/A008) for the same patient on the same day will trigger a rejection for duplicate service.
- Failing to document the specific toxic agent or the clinical severity of the poisoning often leads to audit recovery, as the Ministry requires evidence of the complexity justifying the premium fee.
- Using T668 for routine follow-up visits after the acute toxicological event has resolved is an incorrect application of the code; use standard visit codes instead.
Billing Tips
- Ensure the clinical notes explicitly detail the toxicological assessment and the specific management plan to support the T668 fee during a post-payment audit.
- If the patient requires prolonged critical care beyond the initial assessment, consider whether a time-based critical care code is more appropriate than T668.
