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

This code signifies a fracture of the left kneecap that is broken into two or more pieces and has shifted out of its normal alignment. The patient is receiving follow-up care for this fracture, which is healing as expected without complications, and the skin over the fracture site remains intact.

Use this code for subsequent encounters when a patient with a displaced transverse fracture of the left patella is being monitored for routine healing. This applies to office visits, follow-up imaging, or physical therapy sessions where the fracture is closed and progressing normally.

• Ensure the documentation specifies "displaced" and "transverse" for the patellar fracture.
• Verify the laterality is "left" and the encounter is for "subsequent" care with "routine healing."
• Do not use this code for initial treatment or if complications like delayed healing or nonunion are present.
