Nondisp commnt fx shaft of unsp fibula, 7thN

This code describes a situation where a patient has a comminuted fracture of the fibula shaft that is not displaced, and the fracture is an open fracture (Type IIIA, IIIB, or IIIC). The "N" seventh character indicates that the fracture has not healed as expected and the patient is receiving care for this nonunion during a subsequent encounter.

This code is appropriate for documenting follow-up care for a patient with a previously diagnosed open comminuted fibula shaft fracture that has failed to unite. This includes scenarios where the patient is undergoing treatment for the nonunion, such as bone grafting, revision surgery, or prolonged immobilization. It would be used after the initial treatment of the acute fracture.

• Ensure documentation clearly states "nondisplaced comminuted fracture of fibula shaft" and specifies the open fracture type (IIIA, IIIB, or IIIC).
• Verify that the encounter is for the nonunion of the fracture, not the initial treatment or routine follow-up of a healing fracture.
• Confirm the laterality (left, right, or unspecified) of the fibula fracture is documented; if not specified, the "unspecified" code is appropriate.
