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

This code signifies a left patellar fracture that runs lengthwise, where the bone fragments are no longer in their normal alignment. The patient is in a follow-up phase of treatment, and the fracture is healing as expected without complications, and the skin over the fracture site remains intact.

Use this code for subsequent encounters when a patient is receiving ongoing care for a previously diagnosed displaced longitudinal fracture of the left patella. This applies when the fracture is healing routinely and no surgical intervention or complex treatment is currently being performed, and the fracture is closed.

• Ensure documentation specifies "displaced" and "longitudinal" for the left patella.
• Verify the encounter is for "subsequent care" and "routine healing" of a closed fracture.
• Do not use for initial encounters or for fractures with delayed healing, nonunion, or malunion.
