Nondisp fx of med malleolus of r tibia, 7thK

This code signifies a fracture of the inner ankle bone (medial malleolus) of the right tibia that is still in its correct anatomical position (nondisplaced). The fracture has failed to heal properly after initial treatment, and the patient is presenting for ongoing management of this nonunion.

Apply this code when a patient with a previously diagnosed and treated nondisplaced right medial malleolus fracture presents for follow-up care, and imaging or clinical assessment confirms that the bone fragments have not united. This is appropriate for subsequent encounters where the nonunion is the primary focus of the visit, such as for surgical planning, cast changes, or evaluation of healing progress.

• Ensure documentation clearly states "nonunion" and specifies the "right" medial malleolus.
• Verify the fracture was initially "nondisplaced" and that this is a "subsequent encounter."
• Do not use for initial treatment or routine follow-up of a healing fracture; reserve for confirmed nonunion.
