Displ osteochon fx l patella, subs for clos fx w routn heal

This code signifies a follow-up visit for a left kneecap fracture where a piece of bone and cartilage has broken off and shifted from its normal position. At this stage, the fracture is closed (skin intact) and is healing as expected without complications.

Apply this code for subsequent encounters when a patient with a previously diagnosed displaced osteochondral fracture of the left patella is receiving ongoing care. This includes routine follow-up appointments, cast changes, or physical therapy sessions during the normal healing phase of a closed fracture.

• Ensure documentation specifies "left" patella and "displaced osteochondral" fracture type.
• The "D" seventh character indicates a subsequent encounter for routine healing of a closed fracture.
• Do not use for initial treatment or for fractures with delayed healing or nonunion.
