E592
E592 – Tendon release (open) - more than one
OHIP Surgical Assists Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
This fee code is applicable for an additional open tendon release procedure on the finger or palm, performed during the same surgical session as the primary `R536` (Tendon release [open] finger/palm). It compensates for the additional work of releasing more than one tendon. As a surgical procedure, it may be eligible for age-based premiums as outlined in and after-hours procedure premiums as described on .
When to Use
- Use E592 in conjunction with R536 when performing an open release on a second or subsequent tendon within the same hand or finger during a single operative session.
- Apply E592 when addressing multiple trigger digits or distinct tendon adhesions that require separate open release incisions or distinct surgical maneuvers beyond the primary R536 procedure.
Common Pitfalls
- Billing E592 as a standalone procedure will result in rejection; it must be submitted on the same claim as the primary R536 code.
- Attempting to bill E592 for a single tendon release is a common audit trigger; the primary R536 covers the first tendon, and E592 is strictly for the additional work.
Billing Tips
- Ensure the operative report clearly identifies the specific tendons released to justify both the primary R536 and the additional E592 units.
- If performing bilateral releases, ensure the claim reflects the correct diagnostic codes and site modifiers to support the necessity of multiple E592 units alongside the primary R536.
