Displ commnt fx unsp patella, 7thH

This code signifies a complex patellar fracture that has broken into multiple pieces and is no longer in its normal anatomical position. It specifically indicates that the initial injury was an open fracture (meaning the skin was broken) of either Type I or II severity, and the bone is taking longer than expected to heal during a follow-up visit.

Apply this code during subsequent encounters for patients with a previously diagnosed comminuted, displaced, open patellar fracture (Type I or II) who are experiencing delayed union or non-union. This would be used when the patient is receiving ongoing treatment or evaluation for the slow healing process.

• Ensure documentation clearly specifies "delayed healing" for this subsequent encounter.
• Verify the original injury was an open fracture, Type I or II, as this is a specific inclusion criterion.
• This code is for an unspecified patella; if laterality is known, a more specific code should be used.
