Other mechanical complication of intraocular lens, sequela

This code signifies a long-term or residual issue resulting from a mechanical problem with an intraocular lens (IOL) that is not specifically classified elsewhere. These complications can arise months or years after IOL implantation and may include chronic inflammation, persistent discomfort, or visual disturbances directly attributable to the IOL's mechanical integrity or position.

Use this code when documenting a patient presenting with a chronic or residual mechanical complication of an IOL, such as persistent IOL decentration, tilt, or subluxation that is not acute or actively dislocated. It is appropriate for follow-up encounters addressing the ongoing effects of such a complication after initial treatment or stabilization.

• Always assign this code as a secondary diagnosis when an underlying condition or current treatment for the sequela is also being addressed.
• Ensure documentation clearly links the current mechanical issue to a previously implanted intraocular lens and specifies it as a long-term effect.
• Do not use for acute or initial presentations of IOL dislocation or malposition; those would typically fall under the acute T85.2 series.
