Unsp fx shaft of unsp fibula, 7thN

This code describes a situation where a patient has an unhealed fracture of the shaft of an unspecified fibula, which was initially an open fracture classified as Type IIIA, IIIB, or IIIC. The "nonunion" indicates that the bone has failed to heal completely after a period of time. This code is used for subsequent encounters, meaning the initial treatment has already occurred.

Use this code when documenting ongoing care for a patient with a previously treated, but now unhealed, open fibula shaft fracture (Type IIIA, IIIB, or IIIC). This would apply during follow-up appointments, further surgical interventions for nonunion, or during rehabilitation phases where the nonunion is still being addressed.

• Ensure documentation clearly specifies "nonunion" and the original open fracture type (IIIA, IIIB, or IIIC).
• Verify that this is a subsequent encounter, not the initial treatment for the fracture.
• Confirm the fracture location is the shaft of the fibula; if a specific fibula (left/right) is known, a more specific code should be used.
