Nondisp osteochon fx unsp patella, 7thK

This code signifies a fracture involving both cartilage and underlying bone of the kneecap that is not displaced, meaning the bone fragments are still in their normal alignment. The "subsequent encounter" indicates that the patient is receiving follow-up care for this fracture, and "nonunion" specifies that the fracture has failed to heal completely after the expected healing time.

Use this code for patients presenting for ongoing management of a previously diagnosed nondisplaced osteochondral patellar fracture where imaging or clinical assessment confirms that the fracture has not united. This would include scenarios like follow-up appointments for cast changes, physical therapy, or surgical planning due to the nonunion.

• Ensure documentation clearly states "nondisplaced" and "osteochondral fracture" of the patella.
• The "K" seventh character mandates that the encounter is for follow-up care of a fracture with documented nonunion.
• Always verify the laterality (left, right, or unspecified) of the patella, though this specific code is for unspecified.
