Unsp physl fx upr end rad, unsp arm, subs for fx w malunion

This code signifies an unspecified fracture of the growth plate (physis) at the upper end of the radius bone, with no specific laterality indicated. The fracture is in a subsequent encounter phase, specifically complicated by malunion, meaning the bone has healed in an abnormal position.

Apply this code when a patient presents for follow-up care of a previously diagnosed physeal fracture of the proximal radius that has healed incorrectly. This is appropriate for encounters where the malunion is being addressed or monitored, and the specific side of the body is not documented.

• Ensure documentation clearly states "subsequent encounter" and "malunion" for a physeal fracture of the radius.
• Verify that the laterality (left or right arm) is truly unspecified in the medical record before using this code.
• This code is for the upper end of the radius; confirm the fracture location to avoid miscoding.
