E578 – Interphalangeal dislocation - each additional
OHIP Surgical Assists Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
This code is payable for each additional interphalangeal dislocation reduction, following the initial reduction billed under D027.
When to Use
- Use E578 for the second and any subsequent interphalangeal joint dislocations reduced during the same encounter as the primary reduction billed under D027.
- Apply this code when multiple fingers are injured in a single trauma event and each requires a separate closed reduction procedure.
Common Pitfalls
- Billing E578 as a standalone code without a corresponding D027 will result in an automatic rejection.
- Attempting to use E578 for the initial joint reduction instead of D027 is a common error that leads to payment discrepancies.
- Failing to specify the number of units for E578 when reducing three or more joints will result in underpayment.
Billing Tips
- Ensure the total number of units for E578 matches the number of additional joints reduced beyond the first one billed under D027.
- If performing reductions after hours, remember that the percentage-based premiums (E409 or E410) apply to the total fee of the D027 and the cumulative E578 units.
