C124 – Subsequent visit - day of discharge
OHIP Surgical Procedures Code — CONSULTATIONS AND VISITS · Schedule of Benefits
A subsequent visit rendered by the physician identified as the patient's Most Responsible Physician (MRP) on the day the patient is discharged from the hospital. The service includes the clinical visit and the administrative requirements of discharge coordination.
When to Use
- Use C124 for a standard discharge of an MRP patient who has been hospitalized for at least 48 hours.
- Use C124 when you have performed the final clinical assessment and completed the discharge summary, including medication reconciliation and follow-up planning.
- Use C124 instead of C126 when the patient does not meet the complexity criteria of 7+ days, 3+ diagnoses, and 45+ minutes of care.
Common Pitfalls
- Billing C124 for patients discharged within 48 hours of admission will result in an automatic rejection.
- Attempting to bill C124 on the same day as critical care per diem codes like G521, G522, or G523 is prohibited and will cause a claim conflict.
- Failing to complete the discharge summary within the 48-hour window puts the claim at risk of clawback during an audit.
Billing Tips
- If discharging on a weekend or holiday, ensure you add the E084 premium to the C124 claim to capture the appropriate weekend uplift.
- If the patient is highly complex, verify if they meet the criteria for C126, which provides a higher fee than C124 for the same discharge event.
