Displaced longitudinal fracture of unsp patella, init

This code signifies a break in the kneecap that runs lengthwise, where the bone fragments are no longer in their normal alignment. The specific patella (left or right) is not documented, and the skin over the fracture remains intact. This diagnosis is for the initial treatment phase of the injury.

Apply this code when documentation confirms a longitudinal patellar fracture with displacement, and the encounter is for the primary management of the injury. This includes initial evaluation, reduction, casting, or surgical repair of a closed fracture. Use when laterality of the patella is unspecified in the medical record.

• Ensure documentation explicitly states "displaced" and "longitudinal" for the patellar fracture.
• Confirm the encounter is the "initial encounter" for this specific injury.
• Only use this code when the medical record does not specify whether the fracture is of the left or right patella.
