Nondisp artic fx head of l femr, 7thM

This code describes a fracture involving the joint surface of the left femoral head that has not shifted out of alignment. It specifically indicates that the fracture was initially an open fracture (meaning the bone broke through the skin) of either Type I or Type II severity, and that the bone fragments have failed to heal together properly during a subsequent encounter.

Use this code for follow-up visits where a patient is being treated for a previously diagnosed nondisplaced articular fracture of the left femoral head that was initially open (Type I or II) and is now complicated by nonunion. This applies to ongoing care, including cast changes, wound care, or evaluation for further surgical intervention due to the nonunion.

• Ensure documentation clearly specifies "nondisplaced" and "articular" for the femoral head fracture.
• Verify the initial open fracture type (I or II) and the presence of nonunion during the subsequent encounter.
• This code requires an additional code to specify the type of nonunion (e.g., M84.48XA for nonunion of fracture, femur, initial encounter).
