Nondisp fx of lateral malleolus of l fibula, 7thM

This code describes a left fibula fracture involving the lateral malleolus, where the bone fragments are still in their normal alignment (nondisplaced). It specifically indicates that this is a follow-up encounter for an open fracture (meaning the skin was broken) classified as Type I or Type II, and the fracture is failing to heal properly (nonunion).

Use this code for patients presenting for ongoing treatment of a previously diagnosed nondisplaced open Type I or II lateral malleolus fracture of the left fibula that has not healed as expected. This applies to situations like cast changes, wound care, or evaluation for further surgical intervention due to the nonunion.

• Verify documentation clearly states "nondisplaced" and identifies the "left fibula" and "lateral malleolus."
• Ensure the original injury was an "open fracture type I or II" and the current encounter addresses "nonunion."
• This code is for subsequent encounters; a different code would be used for the initial treatment of the fracture.
