Nondisp artic fx head of unsp femr, 7thM

This code describes a situation where a patient has a fracture of the femoral head that does not involve displacement of the bone fragments, but specifically affects the articular surface. This particular encounter is for ongoing treatment of an open fracture (Type I or II) that has failed to heal properly, resulting in a nonunion.

Use this code for follow-up encounters where a patient is receiving care for a previously diagnosed nondisplaced articular fracture of the femoral head. This is applicable when the initial injury was an open fracture (Gustilo-Anderson Type I or II) and the fracture has not united, requiring further management.

• Ensure documentation specifies "nondisplaced" and "articular" for the femoral head fracture.
• Confirm the original injury was an open fracture, specifically Type I or II, and that nonunion is explicitly documented.
• This code is for subsequent encounters; an initial encounter for the acute fracture would use a different code.
