Breakdown (mechanical) of intraocular lens, subs encntr

This code signifies a mechanical failure or malfunction of an intraocular lens (IOL) that has been previously implanted in the eye. This breakdown can involve issues such as lens dislocation, cracking, or other structural integrity problems, leading to visual disturbances or discomfort.

Apply this code when a patient presents for follow-up care, evaluation, or treatment related to a previously identified mechanical breakdown of their intraocular lens. This includes visits for assessment of the problem, planning for revision surgery, or post-operative care for a repair or replacement.

• Ensure documentation clearly states the encounter is for a subsequent visit related to the IOL breakdown.
• Always code the underlying reason for the IOL implantation (e.g., cataract) as a secondary diagnosis if still relevant.
• Do not use for initial diagnosis of the breakdown; a different seventh character would be appropriate for the initial encounter.
