Oth fx shaft of l femr, 7thN

This code signifies a nonunion of an open fracture of the shaft of the left femur, specifically for Gustilo-Anderson type IIIA, IIIB, or IIIC fractures. Nonunion indicates that the bone has failed to heal completely after a prior fracture, requiring ongoing medical management. This is a subsequent encounter, meaning the patient is receiving care for the complications of the original injury.

Use this code for follow-up encounters when a patient with a previously diagnosed open fracture of the left femoral shaft (Gustilo-Anderson type IIIA, IIIB, or IIIC) is being treated for a confirmed nonunion. This applies when the fracture has not healed within the expected timeframe and further intervention or monitoring is required due to the persistent nonunion.

• Ensure documentation clearly specifies "nonunion" and the Gustilo-Anderson open fracture type (IIIA, IIIB, or IIIC) for the left femoral shaft.
• This is a "subsequent encounter" code; do not use for initial treatment of the fracture or for routine follow-up without a documented nonunion.
• Verify laterality (left femur) is explicitly stated in the medical record.
