Unsp fx upper end of r humerus, subs for fx w malunion

This code indicates an unspecific fracture of the upper part of the right humerus that has healed in an abnormal alignment. This malunion occurred after the initial fracture treatment, and the patient is now receiving ongoing care for this complication.

This code is used when a patient presents for follow-up care, rehabilitation, or further surgical intervention related to a right proximal humerus fracture that has healed incorrectly. It signifies that the initial healing process resulted in a deformity, and the patient is beyond the initial acute treatment phase.

• Ensure documentation clearly states "malunion" and specifies the right humerus.
• Verify this is a subsequent encounter, not an initial treatment for the fracture.
• Look for documentation of previous fracture treatment and current management of the malunion.
