ICD-10-CMDisplaced trimalleolar fracture of right lower leg, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing
This code signifies a complex fracture involving all three malleoli (medial, lateral, and posterior) of the right ankle, which is currently in a routine healing phase. The fracture is open, indicating a break in the skin and exposure of the bone, classified as a severe Type IIIA, IIIB, or IIIC according to the Gustilo-Anderson classification.
Use this code for follow-up encounters where a patient with a previously diagnosed displaced trimalleolar open fracture of the right lower leg (Gustilo-Anderson Type IIIA, IIIB, or IIIC) is receiving ongoing care and the fracture is progressing through an expected, uncomplicated healing period. This applies after the initial treatment and during subsequent visits for monitoring, cast changes, or physical therapy.
