Nondisp trimalleol fx r low leg, init for opn fx type I/2

This code signifies a fracture involving all three malleoli (medial, lateral, and posterior) of the right lower leg, where the bone fragments remain in their normal anatomical alignment. It specifically indicates an open fracture where the skin is broken, but the wound is relatively clean and small, or the bone protrusion is minimal.

Apply this code for initial treatment of a right trimalleolar fracture that is documented as nondisplaced and classified as an open fracture type I or II according to the Gustilo-Anderson classification. This is used when the patient is first presenting for care of this specific injury.

• Ensure documentation explicitly states "nondisplaced" and "trimalleolar" for the right lower leg.
• Confirm the open fracture type (I or II) is clearly documented; otherwise, a different code for unspecified open fracture or closed fracture may be more appropriate.
• This "B" extension indicates an initial encounter, so it should not be used for subsequent care or sequelae.
