Displaced apophyseal fx r femur, subs for clos fx w malunion

This code signifies a fracture of the growth plate (apophysis) in the right thigh bone that has shifted out of alignment and is now healing incorrectly. This "malunion" indicates that the bone fragments have joined together in an abnormal position, potentially leading to functional impairment or deformity.

This code is appropriate for follow-up encounters where a patient with a previously diagnosed displaced apophyseal fracture of the right femur is being treated for the malunion. It specifically applies when the fracture was initially treated non-surgically (closed treatment) and is now demonstrating signs of improper healing.

• Ensure documentation clearly states "malunion" and specifies the right femur and apophyseal fracture type.
• This code is for subsequent encounters; an initial encounter would use a different seventh character.
• Verify that the fracture was treated non-surgically (closed reduction) as indicated by the "P" seventh character.
