Oth fx upr end left rad, subs for opn fx type I/2 w malunion

This code signifies a healed or healing fracture of the upper portion of the left radius that did not align correctly (malunion). Specifically, it applies to cases where the initial injury was an open fracture of type I or II, meaning the skin was broken but the wound was relatively clean and small.

This code is appropriate for follow-up visits where a patient is being treated for complications arising from a malunited fracture of the proximal left radius, originally an open fracture type I or II. It would be used after the initial healing phase, when the malunion is being addressed or monitored.

• Ensure documentation clearly specifies "malunion" and the "left radius" as the affected bone.
• Verify the original fracture was an "open fracture type I or II" to differentiate from other open fracture types or closed fractures.
• This code is for subsequent encounters, not the initial treatment of the fracture or the malunion itself if it's a new diagnosis.
