Unsp fx upr end l rad, subs for opn fx type I/2 w nonunion

This code signifies an unspecified fracture of the upper portion of the left radius that has not healed properly (nonunion). It specifically applies to situations where the initial injury was an open fracture, classified as Type I or Type II, and the patient is presenting for follow-up care related to this ongoing healing complication.

Use this code for a patient who previously sustained an open fracture (Type I or II) of the proximal left radius and is now being seen for management of a nonunion. This would be appropriate for subsequent visits after the initial treatment, where the fracture has failed to unite.

• Ensure documentation clearly states "nonunion" and specifies the fracture as an open Type I or II initially.
• Verify laterality (left radius) and the specific location (upper end/proximal).
• This code indicates a subsequent encounter, so it should not be used for the initial treatment of the fracture.
