Nondisp trimalleol fx unsp low leg, 7thQ

This code describes a trimalleolar ankle fracture that has not shifted out of alignment, affecting an unspecified lower leg. It specifically indicates that the fracture was initially an open fracture (meaning the skin was broken) of either Type I or Type II severity, and has since healed in an imperfect or misaligned position (malunion).

This code is appropriate for follow-up encounters where a patient is being treated for complications arising from a previously sustained, non-displaced trimalleolar open fracture (Type I or II) of an unknown lower leg, and the fracture has healed with malunion. It signifies ongoing care related to the suboptimal healing of the initial injury.

• Ensure documentation clearly specifies "nondisplaced" and "trimalleolar" for the fracture type.
• Verify the original injury was an "open fracture type I or II" and that "malunion" is explicitly documented as a current issue.
• This "Q" seventh character indicates a subsequent encounter for a malunion, not the initial treatment of the fracture.
