Unsp fx upper end left radius, subs for clos fx w malunion

This code signifies an unspecified fracture of the upper end of the left radius that has previously been treated but is now experiencing malunion. Malunion indicates that the bone has healed, but in an unsatisfactory position or alignment. This is a subsequent encounter, meaning the initial treatment has concluded, and the patient is being seen for ongoing management of the healed but malaligned fracture.

Use this code for patients presenting with a previously treated, unspecified fracture of the proximal left radius where imaging or clinical assessment confirms malunion. This applies to follow-up visits after the initial healing period, when the focus is on addressing the consequences of the malunion rather than the acute fracture.

• Ensure documentation clearly specifies "left radius" and "upper end" to support laterality and anatomical site.
• Verify that the encounter is indeed "subsequent" and that malunion is explicitly documented, not just delayed healing or nonunion.
• Consider additional codes for any associated symptoms, complications, or surgical interventions related to the malunion.
