2-part nondisp fx of surg nk of unsp humer, 7thP

This code describes a situation where a patient has a two-part fracture of the surgical neck of an unspecified humerus that was initially nondisplaced. At a subsequent encounter, the fracture is noted to be healing improperly, resulting in malunion.

This code is used when a patient presents for follow-up care of a previously diagnosed two-part nondisplaced surgical neck humeral fracture, and imaging or clinical assessment confirms that the bone fragments have healed in an anatomically incorrect position. It indicates ongoing management of a complication from the initial fracture.

• Ensure documentation clearly states "malunion" and specifies the "surgical neck" of the humerus.
• Verify that the initial fracture was indeed "nondisplaced" and "two-part."
• This code is for subsequent encounters, not the initial treatment of the fracture.
