Displ transverse fx shaft of l femr, 7thN

This code signifies a left femur fracture located in the shaft, which is displaced and has failed to heal (nonunion). It specifically applies to open fractures classified as Type IIIA, IIIB, or IIIC, indicating significant soft tissue damage and contamination. The "subsequent encounter" aspect means the patient is receiving follow-up care for this previously diagnosed and treated fracture.

Use this code when documenting ongoing treatment for a patient with a non-healing, displaced transverse fracture of the left femoral shaft that was initially an open fracture of Gustilo-Anderson Type IIIA, IIIB, or IIIC. This would typically be seen in clinic visits, hospital admissions for revision surgery, or other follow-up care related to the nonunion.

• Always confirm the laterality (left femur) and the specific fracture type (transverse, shaft, displaced).
• Verify documentation explicitly states "nonunion" and the Gustilo-Anderson classification (IIIA, IIIB, or IIIC) for the open fracture.
• Ensure this is a "subsequent encounter" for care related to the nonunion, not the initial treatment.
