Breakdown (mechanical) of intraocular lens, sequela

This code signifies a mechanical failure or structural degradation of an intraocular lens (IOL) that has been surgically implanted to correct vision. This breakdown can manifest as a fracture, dislocation, or other physical compromise of the IOL's integrity, occurring as a long-term consequence of the original implantation.

Use this code when documenting a patient presenting with symptoms or findings directly attributable to a mechanical failure of their previously implanted IOL. This applies to situations where the IOL itself has structurally failed, rather than issues related to its positioning or surrounding tissues. This code is appropriate for reporting the sequela of such a breakdown.

• Ensure documentation clearly states a mechanical breakdown of the IOL, not just a malposition or complication.
• This code is for the sequela (late effect) of the breakdown, indicating it's a current problem stemming from a past event.
• Always code any associated complications or symptoms separately, if applicable.
