Disp fx of low epiphy (separation) of l femr, 7thN

This code describes a fracture of the growth plate at the bottom of the left thigh bone that has shifted out of alignment. It specifically indicates that the fracture is an open fracture (meaning the bone broke through the skin) of a severe type (IIIA, IIIB, or IIIC) and has failed to heal properly after initial treatment.

This code is appropriate for follow-up encounters where a patient is being treated for a nonunion of a previously diagnosed displaced open fracture of the lower left femoral epiphysis. This includes situations where the patient is undergoing further surgical intervention, cast changes, or other management for the persistent nonunion.

• Ensure documentation clearly specifies "nonunion" and the "subsequent encounter" for this specific fracture.
• Verify the laterality (left) and the specific location (lower epiphysis) of the femur fracture.
• Confirm the open fracture type (IIIA, IIIB, or IIIC) is documented, as this is crucial for code selection.
