Bent bone of left rad, subs for opn fx type I/2 w malunion

This code describes a left radius fracture that has healed in an abnormal position (malunion), specifically involving a bent bone. It indicates that the fracture was initially an open fracture of either Type I or Type II, and the current encounter is for follow-up care related to this malunion.

Use this code for patients presenting for ongoing management, evaluation, or treatment of a malunited left radial fracture that was originally an open Type I or II injury. This would include follow-up appointments after initial treatment, or when assessing the functional impact of the malunion.

• Ensure documentation clearly specifies "bent bone" and "malunion" of the left radius.
• Verify the original fracture was an open Type I or II to accurately apply this code.
• Confirm this is a subsequent encounter, not the initial treatment for the fracture or malunion.
