Disp fx of medial malleolus of unsp tibia, init for clos fx

This code signifies a break in the inner ankle bone (medial malleolus) of the tibia, where the bone fragments are not properly aligned. It indicates that this is the first time the fracture is being treated and that the skin over the fracture site is intact.

Apply this code for a patient presenting with a newly diagnosed, non-open fracture of the medial malleolus of the tibia that shows displacement on imaging. This is appropriate for the initial treatment phase, such as emergency department visits or initial orthopedic consultations.

• Ensure imaging reports confirm displacement of the medial malleolus fracture.
• Verify documentation explicitly states "closed fracture" and "initial encounter."
• Do not use this code for open fractures, subsequent encounters, or nonunion/malunion.
