Nondisp fx of low epiphy (separation) of unsp femr, 7thN

This code describes a situation where the growth plate at the bottom of an unspecified femur was previously broken but is now failing to heal properly, specifically in an open fracture that involved significant soft tissue damage (Type IIIA, IIIB, or IIIC). The fracture itself is not displaced, meaning the bone fragments are still in their normal alignment.

Use this code when documenting follow-up care for a patient with a previously diagnosed nondisplaced lower femoral epiphyseal fracture that was an open fracture of type IIIA, IIIB, or IIIC, and the physician has determined that the bone is not uniting as expected. This typically applies during subsequent visits for ongoing treatment, such as cast changes, wound care, or evaluation for further surgical intervention due to nonunion.

• Ensure documentation clearly specifies "nonunion" and the open fracture type (IIIA, IIIB, or IIIC) from the initial injury.
• Verify the fracture is of the lower epiphysis of the femur and is nondisplaced.
• This code is for subsequent encounters, not the initial treatment of the fracture.
