Nondisp artic fx head of unsp femr, 7thR

This code describes a previously sustained fracture of the femoral head that did not involve displacement of the bone fragments at the joint surface. The initial injury was an open fracture classified as type IIIA, IIIB, or IIIC, and the current encounter addresses a complication where the bone has healed in an abnormal position (malunion).

Use this code for follow-up encounters with patients who are being treated for a malunion of a nondisplaced articular femoral head fracture. This applies specifically when the original injury was a severe open fracture (Gustilo-Anderson type IIIA, IIIB, or IIIC). This code would be appropriate for surgical correction of the malunion or ongoing management of its effects.

• Ensure documentation clearly specifies "nondisplaced articular" and "malunion" for the femoral head fracture.
• Verify the original open fracture was classified as type IIIA, IIIB, or IIIC to support the "R" seventh character.
• Always sequence this code after any codes for the current treatment or condition being addressed due to the "subsequent encounter" nature.
