Nondisp seg fx shaft of unsp fibula, 7thN

This code describes a fibula shaft fracture that is broken in multiple places (segmental) but the bone fragments are still in their normal alignment (nondisplaced). It specifically applies to an open fracture (bone broke through the skin) of a severe type (IIIA, IIIB, or IIIC) that has failed to heal properly (nonunion) and is being treated in a subsequent encounter.

Use this code when documenting follow-up care for a patient with a previously diagnosed segmental, nondisplaced open fibula shaft fracture (types IIIA, IIIB, or IIIC) where the fracture has not healed as expected. This would be appropriate for visits related to ongoing management of the nonunion, such as repeat imaging, wound care, or planning for revision surgery.

• Ensure documentation clearly specifies "nondisplaced," "segmental," and "nonunion" for the fibula shaft.
• Verify the original open fracture was classified as type IIIA, IIIB, or IIIC.
• This code is for subsequent encounters; an initial encounter would use a different code.
