E020 – ASA E - Emergency Anaesthesia Premium
OHIP Surgical Assists Code · Schedule of Benefits
When to Use
- Use E020C when performing emergency surgery on an ASA III, IV, or V patient where the procedure commences within 24 hours of the OR booking.
- Apply this premium alongside the appropriate ASA status code (E022C, E017C, or E016C) for urgent surgical interventions that meet the 24-hour booking threshold.
Common Pitfalls
- Billing E020C for ASA I or II patients, which will result in automatic rejection as the premium is restricted to ASA III-V.
- Claiming E020C for elective cases booked more than 24 hours in advance, even if the patient is high-risk.
- Failing to include the base ASA status code (E022C, E017C, or E016C) on the same claim, as E020C is a modifier and not a standalone service.
Billing Tips
- Ensure the OR booking time is clearly documented in the anaesthesia record to support the 'within 24 hours' requirement in the event of an audit.
