Nondisp spiral fx shaft of unsp fibula, 7thM

This code signifies a spiral fracture of the fibular shaft that has not shifted out of alignment. It specifically indicates that the fracture is an open fracture of type I or II, meaning there is a wound communicating with the fracture site, and the bone has failed to heal properly in a subsequent encounter.

This code is used when a patient presents for follow-up care of a previously diagnosed open spiral fibular shaft fracture (Type I or II) that is now complicated by nonunion. This would apply to situations where the patient is undergoing ongoing treatment, such as cast changes, wound care, or planning for further surgical intervention due to the lack of healing.

• Ensure documentation clearly specifies "nondisplaced," "spiral fracture of shaft," and "fibula."
• Verify the open fracture type (I or II) and the presence of nonunion for accurate code assignment.
• This "M" seventh character indicates a subsequent encounter for an open fracture with nonunion, differentiating it from initial or routine follow-up care.
