E571 is an add-on fee payable to the surgeon for the open release of more than one tendon at the wrist. It must be billed in addition to R537 (Tendon release (open), wrist) for each additional tendon released.

When to Use

Use E571 when performing an open release of two or more distinct tendons at the wrist during the same operative session as the primary R537 procedure.
Apply E571 for each additional tendon beyond the first one released, provided the release is open and located at the wrist.

Common Pitfalls

Billing E571 without an associated R537 claim will result in an automatic rejection, as it is strictly an add-on code.
Attempting to use E571 for tendon releases outside the wrist area or for non-open procedures will lead to audit recovery.
Over-billing the number of units for E571; ensure the number of units claimed matches the exact number of additional tendons released beyond the primary R537.

Billing Tips

Clearly document the specific tendons released in the operative report to justify the number of E571 units claimed during a potential audit.
Ensure the primary procedure R537 is billed as the first line item to establish the base for the E571 add-on.
