E558 – Phalanx fracture - each additional
OHIP Surgical Assists Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
This fee code represents the service for the closed reduction of an additional phalanx fracture. It is an add-on code and must be claimed in addition to F005 for each additional phalanx that is reduced beyond the first one during the same operative session. As with all insured services, this includes common elements like arranging appointments, obtaining consent, maintaining medical records, and providing prescriptions as outlined on -.
When to Use
- Use E558 for each additional phalanx fracture requiring closed reduction when the primary fracture is billed under F005.
- Apply this code when multiple fingers or multiple phalanges on the same finger are reduced during the same operative session.
Common Pitfalls
- Billing E558 without an associated F005 will result in an automatic rejection as it is a strictly dependent add-on code.
- Attempting to bill E558 for the first phalanx fracture instead of using F005 will lead to claim adjustment or rejection.
Billing Tips
- Ensure the total number of units for E558 matches the number of additional phalanges reduced beyond the first one to avoid manual review.
