Breakdown (mechanical) of intraocular lens, init encntr

This code signifies a mechanical failure or malfunction of an implanted intraocular lens (IOL). This breakdown can manifest as a fracture, dislocation, or other structural compromise of the IOL itself, distinct from issues related to its positioning or surrounding tissues.

Apply this code when a patient presents with symptoms directly attributable to a structural defect or mechanical failure of their IOL, such as decreased vision, glare, or pain, and it is the initial presentation or treatment for this specific IOL breakdown. This is appropriate for the first encounter where the mechanical breakdown is diagnosed and managed.

• Ensure documentation clearly specifies a mechanical breakdown of the IOL, not just a malposition or complication of the surrounding capsule.
• Confirm this is the initial encounter for the specific mechanical breakdown; subsequent encounters would use a different seventh character.
• Distinguish from complications related to the IOL's presence, such as inflammation or infection, which would be coded separately.
