Displ longitud fx r patella, 7thM

This code signifies a displaced fracture running lengthwise through the right kneecap that has failed to heal properly. It specifically applies to cases where the initial injury was an open fracture, classified as Type I or Type II, and the patient is now presenting for follow-up care related to this nonunion.

Apply this code when documenting a patient's visit for ongoing management of a right patellar nonunion, where the original injury was an open longitudinal fracture. This is appropriate for subsequent encounters after the initial treatment, indicating the fracture has not united as expected.

• Ensure documentation clearly states "nonunion" and specifies the right patella.
• Verify the original fracture was an open Type I or II longitudinal patellar fracture.
• This code is for subsequent encounters, not the initial injury or active treatment of the acute fracture.
