Oth fx shaft of right ulna, subs for clos fx w malunion

This code signifies a follow-up visit for a patient who previously sustained a closed fracture of the shaft of their right ulna, and that fracture has healed in an unsatisfactory position, known as a malunion. The "other fracture" designation indicates it's not a greenstick, transverse, oblique, spiral, or comminuted fracture.

This code is appropriate when a patient presents for ongoing management or evaluation of a malunited closed fracture of the right ulnar shaft. This could include assessment for corrective surgery, physical therapy, or monitoring of functional limitations due to the malunion. It is used after the initial treatment of the fracture.

• Ensure documentation clearly states "malunion" and specifies the right ulna shaft.
• Verify the encounter is for follow-up care, not the initial treatment of the fracture.
• Confirm the fracture was initially closed; open fractures have different coding pathways.
