Oth disp fx of upper end of l humer, subs for fx w malunion

This code signifies a malunion of a previously displaced fracture of the proximal end of the left humerus. It indicates that the fracture has healed, but in an anatomically incorrect or misaligned position, leading to potential functional impairment. This is a subsequent encounter, meaning the patient is being seen for ongoing management of this specific malunion.

Use this code for follow-up encounters where a patient is being managed for a malunited fracture of the proximal left humerus that was initially displaced. This applies when the malunion is the primary focus of the visit, such as for evaluation of function, pain management, or consideration of corrective surgery.

• Ensure documentation clearly specifies "malunion" and not "nonunion" or "delayed healing," as these have different codes.
• Verify the laterality (left) and the specific bone/location (upper end of humerus) are accurately documented.
• Confirm this is a subsequent encounter for the fracture; initial encounters or sequelae of the malunion would use different codes.
