Nondisp fx of med malleolus of r tibia, 7thM

This code describes a fracture of the inner ankle bone (medial malleolus) of the right tibia that has not shifted out of place. It specifically indicates that the initial injury was an open fracture (meaning the skin was broken) of either Type I or Type II, and the bone is now failing to heal properly (nonunion).

This code is used when a patient is receiving ongoing treatment for a right medial malleolus fracture that was initially an open fracture (Type I or II) and is now experiencing nonunion. This would apply to follow-up visits, cast changes, or surgical interventions aimed at promoting healing of the nonunion.

• Ensure documentation clearly specifies "nondisplaced" and "right" for the medial malleolus.
• Verify the original injury was an open fracture type I or II, as this impacts the "S" category.
• The "M" seventh character indicates a subsequent encounter for a nonunion, so confirm the patient is past the initial healing phase.
