Nondisp spiral fx shaft of r fibula, 7thN

This code describes a specific type of fibula fracture: a spiral break in the shaft of the right fibula that has not shifted out of alignment. It indicates that the fracture is an open fracture (meaning the bone broke through the skin) of a severe type (IIIA, IIIB, or IIIC), and that the bone is failing to heal properly (nonunion). This particular code is used for follow-up care after the initial treatment.

Use this code when documenting ongoing treatment for a patient with a previously diagnosed nondisplaced spiral fracture of the shaft of the right fibula. The fracture must have been an open fracture of type IIIA, IIIB, or IIIC, and the current encounter addresses the complication of nonunion. This would apply to scenarios such as subsequent clinic visits, surgical interventions for nonunion, or wound care related to the open fracture.

• Ensure documentation clearly specifies "nondisplaced" and "spiral fracture of shaft of right fibula."
• Verify the original injury was classified as an open fracture type IIIA, IIIB, or IIIC and that nonunion is explicitly documented.
• This "N" seventh character indicates a subsequent encounter for nonunion; do not use for initial treatment or routine healing.
