Unsp fx low end r femr, 7thN

This code signifies a persistent failure of a severe open fracture at the lower end of the right femur to heal properly, specifically when the initial injury involved significant soft tissue damage and contamination (Type IIIA, IIIB, or IIIC). It indicates that the patient is receiving ongoing treatment for this nonunion.

Use this code for follow-up encounters when a patient is being managed for a previously diagnosed open fracture of the distal right femur that has failed to unite, and the original injury was classified as an open fracture type IIIA, IIIB, or IIIC. This applies to situations such as surgical revisions, prolonged immobilization, or ongoing wound care related to the nonunion.

• Ensure documentation clearly specifies "nonunion" and the "subsequent encounter" for treatment.
• Verify the original open fracture type (IIIA, IIIB, or IIIC) is documented to support the specificity of this code.
• Do not use for initial encounters or for fractures that are healing normally.
