Nondisp fx of medial malleolus of left tibia, init

This code describes a break in the inner ankle bone (medial malleolus) of the left lower leg, where the bone fragments have not shifted out of alignment. It indicates the first time this specific injury is being treated, and the skin over the fracture is intact.

Apply this code for patients presenting with a newly diagnosed, non-displaced fracture of the medial malleolus on the left side. This is appropriate for the initial evaluation and management of such a closed injury, typically following trauma like a fall or twisting injury.

• Ensure documentation explicitly states "nondisplaced" and identifies the "left" medial malleolus.
• Confirm this is the patient's first encounter for this specific fracture; subsequent care would use a different encounter character.
• Verify the fracture is closed (skin intact) to avoid using codes for open fractures.
