Mech compl of intraocular lens, initial encounter

This code signifies a mechanical issue with an intraocular lens (IOL) that is not specifically categorized elsewhere, occurring during the initial phase of treatment. These complications can include a variety of structural problems with the IOL itself or its positioning within the eye, leading to visual disturbances or discomfort.

Apply this code when a patient presents for the first time with a mechanical complication of an IOL that doesn't fit more specific codes (e.g., dislocation, malposition, or prolapse). Examples include a fractured haptic, a scratched or damaged optic, or an IOL that is otherwise structurally compromised.

• Always use an additional code to specify the exact nature of the mechanical complication, if known.
• Ensure the encounter is truly "initial" for the specific complication being treated. Subsequent encounters would use a different seventh character.
• Distinguish this from complications related to infection or inflammation, which would be coded separately.
