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

This code signifies a fracture running lengthwise through the left kneecap that has shifted from its normal alignment. The patient is currently in a follow-up period for this injury, and the bone healing process is taking longer than typically expected for a closed fracture.

Apply this code when documenting a patient's visit for ongoing management of a previously diagnosed displaced longitudinal fracture of the left patella. This is specifically for situations where the fracture is not yet fully healed, and the healing process has been complicated by a delay.

• Requires a seventh character "G" for subsequent encounter with delayed healing.
• Ensure documentation explicitly states "displaced" and "longitudinal" for the patella fracture.
• Confirm the fracture is "closed" and that delayed healing is noted by the provider.
