Nondisp bimalleol fx unsp low leg, 7thK

This code signifies a bimalleolar fracture of the lower leg, meaning both the medial and lateral malleoli are broken, but the bone fragments remain in their normal anatomical alignment. The "subsequent encounter" indicates the patient is receiving follow-up care for this fracture, and "nonunion" specifies that the fracture has failed to heal completely after a reasonable period.

Use this code for patients presenting for ongoing treatment, such as cast changes, physical therapy, or surgical planning, for a previously diagnosed nondisplaced bimalleolar fracture of an unspecified lower leg that has not united. This applies when the physician explicitly documents nonunion of the fracture.

• Ensure documentation clearly states "nondisplaced" and "bimalleolar fracture" of the lower leg.
• Verify that the encounter is for follow-up care and that "nonunion" is explicitly documented by the provider.
• Do not use this code for initial treatment or for malunion or delayed union; specific codes exist for those conditions.
