Unsp fx low end l femr, 7thN

This code signifies a persistent failure of a severe open fracture at the lower end of the left thigh bone to heal properly, specifically when the fracture was initially classified as Type IIIA, IIIB, or IIIC. "Nonunion" indicates that the bone fragments have not united after a sufficient healing period, requiring further medical intervention. This condition implies significant soft tissue damage and a high risk of infection associated with the initial injury.

Use this code for a patient presenting for follow-up care, treatment, or evaluation of an unhealed, previously diagnosed severe open fracture of the distal left femur. This applies when the initial injury involved extensive soft tissue damage and contamination, and the bone has failed to mend. It is appropriate for subsequent encounters after the initial treatment of the fracture.

• Ensure documentation clearly specifies "nonunion" and the initial open fracture type (IIIA, IIIB, or IIIC) for the lower end of the left femur.
• This code is for subsequent encounters; a different code would be used for the initial treatment of the fracture.
• Verify laterality (left femur) is explicitly stated in the medical record.
