Nondisp apophyseal fx r femr, 7thN

This code signifies a non-displaced fracture of the growth plate (apophysis) of the right femur that has failed to heal properly, specifically when the fracture was initially an open fracture of severe type (IIIA, IIIB, or IIIC). The "subsequent encounter" indicates that the patient is receiving follow-up care for this nonunion.

Use this code when documenting ongoing treatment for a patient with a previously diagnosed, non-displaced apophyseal fracture of the right femur that was an open fracture (Type IIIA, IIIB, or IIIC) and has now progressed to a nonunion. This would include scenarios such as surgical intervention for nonunion, cast changes, or follow-up appointments to monitor healing progress of the nonunion.

• Ensure documentation clearly specifies "nonunion" and the initial open fracture type (IIIA, IIIB, or IIIC).
• Verify the fracture is indeed "nondisplaced" and located in the "apophysis" of the right femur.
• Confirm this is a subsequent encounter for the nonunion, not the initial treatment of the fracture.
