E590 – Rigid external fixation - pseudoarthrosis
OHIP Surgical Assists Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
Payable in addition to the primary procedure for the application of rigid external fixation for the treatment of pseudoarthrosis. This code is found in the Fixation subsection of the Musculoskeletal System Surgical Procedures section on page of the Schedule.
When to Use
- Use E590 when applying a rigid external fixation device specifically to manage a non-union or pseudoarthrosis of a long bone.
- Apply this code as an add-on to the primary surgical procedure (e.g., bone grafting or debridement) performed to address the pseudoarthrosis.
Common Pitfalls
- Do not bill E590 for routine fracture stabilization; it is strictly reserved for the treatment of established pseudoarthrosis.
- Avoid billing E590 as a standalone procedure; it must be linked to a primary surgical code to be considered valid by OHIP.
- Ensure the documentation explicitly confirms the diagnosis of pseudoarthrosis, as billing this for simple delayed union may lead to audit recovery.
Billing Tips
- Always append E590 to the primary procedure code on the same claim to ensure the add-on logic is correctly processed by the system.
