C143 – Second subsequent visit by the MRP following transfer from an Intensive Care Area
OHIP Surgical Procedures Code — CONSULTATIONS AND VISITS · Schedule of Benefits
Second subsequent visit by the MRP following patient’s transfer from an Intensive Care Area (including Neonatal Intensive Care) where the patient was receiving Critical Care, Ventilatory Support, Comprehensive Care or Neonatal Intensive Care services immediately prior to the time of the transfer to an acute care hospital bed in the same hospital.
When to Use
- Use C143 specifically for the second subsequent visit by the MRP on the day following the first visit (C142) after a patient is stepped down from an ICU to a general ward.
- Use this code when managing a patient who required active ventilatory or comprehensive critical care support immediately prior to the ward transfer.
Common Pitfalls
- Billing C143 if you were the physician who provided the critical care services in the ICU prior to the transfer, as this is explicitly prohibited by the Schedule of Benefits.
- Attempting to bill C143 when the patient is discharged on the same day, as C143 is strictly prohibited on the day of discharge (C124/C126).
- Submitting C143 more than once per hospital admission, as it is a one-time-only code per patient stay.
Billing Tips
- Ensure your billing sequence follows C142 for the first post-transfer visit and C143 for the second, as these are the only two codes permitted for this specific transition period.
