Displ transverse fx unsp patella, 7thK

This code describes a situation where a patient has a transverse fracture of the kneecap that is no longer in its proper alignment. The fracture is being treated, but the bone fragments have failed to heal together after an expected period, and the skin over the fracture remains intact.

Use this code for follow-up encounters when a patient with a previously diagnosed displaced transverse patellar fracture is experiencing nonunion of the bone fragments, and the fracture is still considered closed. This applies to ongoing management, assessment of healing, or preparation for further intervention due to the nonunion.

• Ensure documentation clearly states "nonunion" and specifies the fracture as "transverse" and "displaced."
• Verify that the encounter is for follow-up care of a closed fracture, not an initial treatment or an open fracture.
• This code requires an additional code for any associated complications or treatment modalities.
