Unsp fracture of unsp patella, subs for clos fx w nonunion

This code signifies a fracture of the kneecap where the specific type of fracture is not documented, and the affected patella (left or right) is also unspecified. It is used when the patient is receiving follow-up care for a closed fracture that has failed to heal properly, resulting in a nonunion.

This code is appropriate for subsequent encounters when a patient presents with a previously diagnosed, unspecified patellar fracture that is not healing as expected and is now complicated by nonunion. This would include situations where surgical intervention for the nonunion is being planned or performed, or during ongoing conservative management for the nonunion.

• Always strive for greater specificity regarding the patella (left/right) and the type of fracture if documented.
• Ensure the documentation clearly states "nonunion" and that the fracture was initially closed.
• This code requires an "K" seventh character, indicating a subsequent encounter for a nonunion.
