Displ transverse fx l patella, subs for clos fx w malunion

This code signifies a fracture of the left kneecap that runs across the bone, where the broken ends are not properly aligned. The patient is in a later stage of care for this injury, and the fracture has healed in an unsatisfactory position, leading to a deformity.

Apply this code when documenting follow-up care for a patient who previously sustained a transverse fracture of the left patella, and imaging or clinical assessment confirms that the fracture has healed with a noticeable malunion. This would be used in scenarios such as evaluating persistent pain or functional limitations due to the malunion, or planning for corrective surgery.

• Ensure documentation clearly states "left" patella and "transverse" fracture.
• Verify that the encounter is for follow-up care and not the initial treatment.
• Confirm that the malunion is explicitly documented, indicating improper healing.
