Displ longitud fx r patella, subs for clos fx w delay heal

This code signifies a fracture of the right kneecap that runs lengthwise and is no longer in its anatomical alignment. The patient is in a later phase of treatment for this injury, and the healing process is taking longer than expected, despite the skin remaining intact over the fracture site.

Apply this code when documenting follow-up care for a patient with a previously diagnosed displaced longitudinal fracture of the right patella. This is appropriate when the physician notes delayed healing of the closed fracture during a subsequent visit. This code would be used for services such as cast changes, physical therapy evaluations, or follow-up imaging to assess healing progress.

• Ensure documentation explicitly states "delayed healing" for this specific fracture.
• Verify the fracture is indeed "displaced" and "longitudinal" to the right patella.
• Confirm this is a "subsequent encounter" and the fracture is "closed."
