E579 – Metatarsophalangeal dislocation - each additional
OHIP Surgical Assists Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
This service is for the application of each additional plaster cast for a metatarsophalangeal dislocation, following the application of the first cast (E584). It is intended to be used as an add-on to the closed reduction procedure (D030). This service is only payable for procedures performed outside of a hospital setting.
When to Use
- Use E579 only when a second or subsequent plaster cast is applied to the same metatarsophalangeal joint following the initial application of E584.
- Apply this code exclusively for procedures performed in an office or clinic setting, as it is strictly prohibited for hospital-based care.
Common Pitfalls
- Billing E579 without a corresponding E584 on the same claim will result in an automatic rejection.
- Attempting to bill E579 for a hospital-based procedure is a common audit trigger, as the code is explicitly restricted to non-hospital settings.
- Submitting E579 without the primary closed reduction code D030 will lead to claim denial, as the entire sequence must be linked to the reduction procedure.
Billing Tips
- Ensure the clinical record clearly justifies the medical necessity for multiple cast applications to support the use of E579 as an add-on.
- Apply after-hours premiums like E409 or E410 to the base procedure and the E579 add-on if the criteria for non-elective, after-hours care are met.
