Oth intartic fx low end l rad, subs for clos fx w nonunion

This code signifies a fracture within the joint space of the lower end of the left radius that is not healing properly (nonunion). The fracture is currently closed, meaning the skin over the injury is intact, and the patient is receiving follow-up care for this specific injury.

Use this code when documenting a patient's subsequent visit for an intra-articular fracture of the distal left radius that has been identified as a nonunion. This applies to ongoing management, such as monitoring, casting changes, or preparation for surgical intervention for the nonunion.

• Requires a seventh character "K" for subsequent encounter for closed fracture with nonunion.
• Ensure documentation clearly states "nonunion" and specifies the left radius and intra-articular involvement.
• Do not use for initial encounter or for malunion; separate codes exist for those scenarios.
