Unsp physl fx upr end humer, unsp arm, 7thP

This code describes a fracture of the growth plate (physis) at the top of the humerus (upper arm bone) that occurred in an unspecified arm. The fracture is now in a healing phase, but it has healed incorrectly, resulting in a malunion.

Use this code for follow-up encounters where a patient is being treated for a previously diagnosed, unspecified physeal fracture of the proximal humerus that has healed in an abnormal position. This indicates the fracture has united, but with an unacceptable alignment or deformity.

• Ensure documentation clearly states "malunion" and specifies the "subsequent encounter" for the fracture.
• This code is for an unspecified arm; if the laterality is known, a more specific code should be used.
• Always sequence this code after the primary reason for the encounter if the malunion is being addressed.
