Nondisp fx of med malleolus of r tibia, 7thN

This code describes a specific type of healing complication for a right ankle fracture. It indicates a fracture of the medial malleolus (the inner ankle bone) that was initially an open fracture (meaning the skin was broken) of a severe type (IIIA, IIIB, or IIIC), but the bone fragments are currently in their normal anatomical position (nondisplaced). The key clinical feature is that the bone has failed to heal properly, known as nonunion, and the patient is in a subsequent phase of care.

Use this code when documenting a patient's follow-up visit for a previously treated open fracture of the right medial malleolus that has not healed and is now considered a nonunion. This applies when the fracture fragments are no longer displaced, indicating either successful reduction or that displacement was not present at the time of nonunion diagnosis. It is appropriate for ongoing management of this specific healing complication.

• Ensure the documentation clearly specifies "nonunion" and the "subsequent encounter" for this condition.
• Verify the initial injury was an "open fracture" of type IIIA, IIIB, or IIIC, as this is a specific characteristic of the code.
• Confirm the fracture is "nondisplaced" at the time of this encounter, differentiating it from displaced nonunions.
