Displ osteochon fx left patella, subs for clos fx w malunion

This code signifies a fracture involving both the bone and cartilage of the left kneecap, where the fractured pieces are not properly aligned. This particular code is used when the patient is receiving follow-up care for a fracture that has previously been treated, but has healed in an unsatisfactory position.

Apply this code for patients presenting for ongoing management of a left patellar osteochondral fracture that has healed with a deformity or misalignment. This would include scenarios such as physical therapy, follow-up imaging, or evaluation for corrective surgery after initial treatment has concluded and malunion is identified.

• Ensure documentation clearly states "left patella" and "osteochondral fracture" with evidence of displacement.
• The "P" seventh character indicates a subsequent encounter for a closed fracture with malunion, so verify the patient is past the initial active treatment phase and malunion is documented.
• Distinguish from nonunion (S82.012N) or routine follow-up without malunion (S82.012D, S82.012G, S82.012K, S82.012M).
