Nondisp commnt fx shaft of ulna, r arm, 7thQ

This code signifies a right arm injury involving a comminuted fracture of the ulna shaft that is not displaced. It specifically indicates that the fracture was initially an open fracture of either Type I or Type II, and the current encounter addresses a complication of malunion.

Use this code when a patient presents for follow-up care or treatment of a malunion stemming from a previously sustained open, comminuted, nondisplaced fracture of the right ulnar shaft. This would apply to scenarios such as surgical correction of the malunion or ongoing management of its effects.

• Ensure documentation clearly specifies "malunion" as the reason for the subsequent encounter.
• Verify the original fracture was an open fracture, Type I or II, and involved the right ulna shaft.
• Do not use for nonunion, delayed union, or routine follow-up without malunion.
