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

This code describes a fracture of the right kneecap that has broken into multiple pieces but where the bone fragments are still in their normal anatomical position. The "subsequent encounter" indicates the patient is receiving follow-up care for this fracture, and "nonunion" specifies that the bone is failing to heal properly.

This code is appropriate for encounters where a patient is being treated for a previously diagnosed, nondisplaced comminuted fracture of the right patella that has not healed as expected. This includes situations where the patient is undergoing evaluation for nonunion, receiving treatment for nonunion, or being monitored for delayed healing.

• Ensure documentation clearly states "nondisplaced," "comminuted," and "right patella."
• Verify that the encounter is for follow-up care and not the initial treatment of the fracture.
• Confirm that the physician's assessment explicitly mentions "nonunion" or a similar term indicating failed healing.
