Nondisp commnt fx l patella, subs for clos fx w routn heal

This code describes a left kneecap fracture that has broken into multiple pieces but remains in its anatomical position. The patient is in the healing phase following initial treatment, and the fracture is progressing as expected without complications.

Apply this code for follow-up encounters where a patient is receiving ongoing care for a previously diagnosed nondisplaced comminuted fracture of the left patella. This includes routine cast changes, physical therapy evaluations, or follow-up imaging to assess healing progress, provided the fracture is closed and healing routinely.

• Ensure documentation specifies "left" patella and "nondisplaced comminuted" fracture type.
• The 7th character "D" indicates a subsequent encounter for routine healing of a closed fracture.
• Do not use if the fracture is open, displaced, or experiencing delayed/nonunion healing.
