Displ artic fx head of r femur, subs for clos fx w nonunion

This code signifies a fracture of the head of the right femur that extends into the joint surface, where the bone fragments are no longer in their normal alignment. The fracture has failed to heal properly (nonunion), and the patient is presenting for follow-up care or treatment after the initial management of the closed fracture.

Use this code for patients presenting for ongoing treatment, evaluation of nonunion, or surgical intervention for a previously diagnosed and initially treated displaced articular fracture of the right femoral head. This applies when the fracture was initially closed and has subsequently developed a nonunion.

• Ensure documentation clearly states "nonunion" and specifies the right femur and articular involvement.
• Verify the encounter is for subsequent care, not the initial treatment of the fracture.
• Confirm the original fracture was closed; open fractures would require a different subsequent encounter code.
