Nondisp fx of med malleolus of unsp tibia, 7thM

This code describes a fracture of the inner ankle bone (medial malleolus) of the tibia that is not displaced, meaning the bone fragments are still in their normal alignment. It specifically indicates an open fracture (skin broken) of Type I or II, which is now experiencing nonunion, meaning the bone is failing to heal properly. This is a subsequent encounter, indicating ongoing treatment for the nonunion.

Use this code for follow-up encounters where a patient is being treated for a previously diagnosed, nondisplaced, open Type I or II medial malleolus fracture of an unspecified tibia that has developed nonunion. This would apply to situations such as casting changes, wound care, or surgical planning for the nonunion.

• Ensure documentation clearly states "nondisplaced" and "medial malleolus" of the tibia.
• Confirm the fracture was initially an "open fracture type I or II" and that "nonunion" is explicitly documented.
• Verify this is a "subsequent encounter" for ongoing management of the nonunion, not the initial treatment.
