G559
G559 – Critical care - 31st day onwards
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
When to Use
- Use G559 for the physician-in-charge when a patient remains in critical care beyond the 30-day limit covered by G558.
- Apply this code for daily management of a patient who has exhausted the maximum 29 units of G558 in a single critical care episode.
Common Pitfalls
- Billing G559 concurrently with C101 will result in an automatic rejection as these services are mutually exclusive.
- Attempting to bill G559 before the 31st day of the critical care sequence will trigger a rejection, as the system strictly enforces the chronological progression from G557 to G558 to G559.
Billing Tips
- Ensure your patient record clearly tracks the cumulative days of critical care to justify the transition from G558 to G559 upon the 31st day.
