Nondisp commnt fx left patella, subs for clos fx w nonunion

This code signifies a comminuted fracture of the left kneecap that is not displaced, meaning the bone fragments are still in their anatomical position. The "subsequent encounter" indicates the patient is receiving follow-up care for this fracture, and "nonunion" specifies that the bone has failed to heal properly.

Apply this code when documenting ongoing treatment for a previously diagnosed nondisplaced comminuted left patellar fracture that has not united. This includes scenarios where the patient is undergoing conservative management, physical therapy, or surgical intervention to address the nonunion. It would also be used for follow-up appointments to monitor the healing process or lack thereof.

• Ensure documentation clearly states "nondisplaced," "comminuted," and "left patella."
• Verify the encounter is for follow-up care related to the fracture and not the initial treatment.
• Confirm the physician's assessment explicitly states "nonunion" of the fracture.
