Oth fracture of right patella, subs for clos fx w nonunion

This code signifies a fracture of the right kneecap, other than a transverse, comminuted, or unspecified type, that has not healed properly (nonunion). The fracture is currently closed, meaning the skin over the injury is intact. This encounter is for ongoing treatment or follow-up of this specific nonunion.

Use this code when a patient presents for management of a previously diagnosed, non-healing closed fracture of the right patella. This includes scenarios such as follow-up appointments, physical therapy for the nonunion, or evaluation for surgical intervention to address the nonunion. It is appropriate for any encounter after the initial treatment of the fracture.

• Always sequence this code after the appropriate external cause code if applicable.
• Ensure documentation clearly states "nonunion" and specifies the "right patella" and "closed fracture."
• Verify that this is not the initial encounter for the fracture; if it is, a different code from the S82.091 series would be appropriate.
