Oth fx upper end of left radius, subs for clos fx w nonunion

This code signifies a non-union of a previously sustained fracture in the upper portion of the left radius, excluding the radial head or neck. Non-union indicates that the bone has failed to heal completely after the initial injury, and this encounter is for ongoing management of the closed fracture.

Apply this code for follow-up visits where a patient is being treated for a non-united fracture of the proximal left radius, and the fracture was initially closed. This includes scenarios such as cast changes, physical therapy evaluations, or discussions regarding further surgical intervention for the non-union.

• Ensure documentation clearly states "nonunion" and specifies the "left radius" and "upper end" (excluding head/neck).
• Verify the encounter is "subsequent" and the initial fracture was "closed."
• Do not use for initial fracture treatment or for malunion, which is coded differently.
