Nondisp transverse fx shaft of l ulna, 7thR

This code signifies a follow-up encounter for a patient who previously sustained a transverse fracture of the shaft of their left ulna. The fracture was initially an open fracture of type IIIA, IIIB, or IIIC, and has subsequently healed with malunion, meaning the bone fragments have united in a deformed or misaligned position. The fracture itself is currently nondisplaced.

This code is appropriate for documenting subsequent patient visits where the primary focus is the ongoing management or assessment of a malunited, previously open, transverse left ulnar shaft fracture. This includes scenarios such as monitoring the malunion, planning for corrective surgery, or evaluating the functional impact of the malunion. It should be used after the initial treatment phase for the acute fracture.

• Ensure documentation clearly specifies "subsequent encounter" and confirms the presence of malunion.
• Verify the original fracture was an open fracture type IIIA, IIIB, or IIIC, as this is a specific inclusion criterion.
• Do not use for initial treatment of the fracture or for nonunion; specific codes exist for those scenarios.
