Nondisp commnt fx unsp patella, init for opn fx type 3A/B/C

This code describes a fracture of the kneecap that has broken into three or more pieces (comminuted) but where the bone fragments remain in their normal anatomical position (nondisplaced). It specifically indicates an open fracture where the skin and soft tissues are severely damaged, exposing the bone, and is being treated for the first time.

Use this code for a patient presenting with a newly diagnosed, comminuted, nondisplaced patellar fracture that is open, with significant soft tissue damage (Type IIIA, IIIB, or IIIC). This is appropriate for the initial surgical or non-surgical management of such an injury, prior to any subsequent care phases.

• Ensure documentation clearly specifies "nondisplaced" and "comminuted" for the patellar fracture.
• Verify the open fracture type (IIIA, IIIB, or IIIC) is explicitly stated or clearly implied by the severity of soft tissue damage.
• This "C" encounter code is only for the initial treatment phase of the open fracture.
