ICD-10-CMNondisplaced trimalleolar fracture of right lower leg, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing
This code describes a specific type of ankle fracture involving all three malleoli (medial, lateral, and posterior) in the right lower leg, which has not shifted out of alignment. It indicates that the fracture was initially an open fracture (meaning the skin was broken) of a severe type (IIIA, IIIB, or IIIC) and is now in a phase of routine healing.
Use this code when documenting follow-up care for a patient with a previously diagnosed nondisplaced trimalleolar fracture of the right lower leg that was initially an open fracture of type IIIA, IIIB, or IIIC. This applies when the patient is progressing through the expected healing process without complications. It is appropriate for office visits, cast changes, or imaging reviews during the healing phase after initial treatment.
