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

This code describes a situation where a patient has a previously treated, nondisplaced fracture of the growth plate at the lower end of their right thigh bone. The fracture was an open fracture (meaning the bone broke through the skin) of a severe type (IIIA, IIIB, or IIIC), and despite prior treatment, the bone has failed to heal properly.

Use this code for follow-up encounters when a patient with a history of a severe open lower right femoral epiphyseal fracture is being treated for nonunion. This indicates ongoing management for the failure of the bone fragments to unite after the initial injury and subsequent treatment.

• Ensure documentation clearly specifies "nondisplaced" and "right femur" for laterality and displacement.
• Confirm the encounter is for "subsequent" care and specifically addresses the "nonunion" of a previously open fracture type IIIA, IIIB, or IIIC.
• Do not use this code for initial treatment or for malunion; nonunion must be explicitly documented.
