Unsp fx head of l femr, 7thN

This code signifies a non-healing fracture of the head of the left femur that was initially an open fracture of severe type (IIIA, IIIB, or IIIC). "Nonunion" indicates that the bone fragments have failed to heal together after a significant period. This diagnosis points to a persistent and complicated injury requiring ongoing medical management.

Use this code for follow-up encounters when a patient presents with a previously diagnosed open fracture of the left femoral head (severe type) that has not healed. This applies to situations where the physician is assessing or treating the nonunion, such as for surgical planning, cast changes, or monitoring healing progress.

• Ensure documentation clearly specifies "nonunion" and the initial open fracture type (IIIA, IIIB, or IIIC).
• Verify the fracture location is specifically the "head of the left femur."
• This code is for subsequent encounters; an initial encounter would use a different code.
