E504 – Metacarpal - each additional
OHIP Surgical Assists Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
This fee code is payable for each additional metacarpal fracture that undergoes a closed reduction during the same operative session. It is an add-on to F009, which covers the first metacarpal fracture reduction.
When to Use
- Use E504 when performing a closed reduction on a second or subsequent metacarpal fracture during the same operative session as the primary reduction billed under F009.
- Use this code for each additional metacarpal bone treated; if you reduce three metacarpal fractures, you should bill F009 for the first and E504 twice.
Common Pitfalls
- Billing E504 without an associated F009 on the same claim will result in an automatic rejection.
- Do not use E504 for phalangeal fractures; those require different codes such as F008 or F011 depending on the specific anatomy and procedure.
- Attempting to bill E504 for open reductions is incorrect, as this code is strictly defined for closed reductions.
Billing Tips
- Ensure the number of units for E504 matches the number of additional metacarpals reduced to avoid manual review or claim adjustment.
- If after-hours premiums like E409 or E410 apply, ensure they are calculated based on the total procedural fee including the E504 add-on.
