Unsp fx upper end of right ulna, subs for clos fx w malunion

This code signifies an unspecified fracture of the upper portion of the right ulna that is currently being treated for a malunion. A malunion indicates that the fracture has healed, but in an unsatisfactory or misaligned position. This specific encounter is for ongoing management of the closed fracture with this complication.

Use this code when a patient presents for follow-up care, rehabilitation, or further intervention related to a previously sustained, unspecified fracture of the right proximal ulna that has healed incorrectly. This applies to situations where the malunion is the primary focus of the current encounter, and the fracture was initially closed.

• Ensure documentation clearly states "malunion" and specifies the "right ulna" and "upper end."
• Verify that the encounter is for a "subsequent encounter" and the original fracture was "closed."
• Do not use this code for initial treatment of the fracture or for nonunion, which is a separate complication.
