Intraoperative Floppy Iris Syndrome

A patient with senile nuclear cataract underwent nuclear cataract phacoemulsification with insertion of prosthetic intraocular lens. The patient had been taking prescribed alpha-1 blocker medication. Because of the risk for intraoperative floppy iris syndrome (IFIS), the surgeon utilized pupil expansion devices during the procedure. The surgeon's final diagnosis listed senile nuclear cataract and IFIS related to alpha-1 blocker medication. What are the appropriate diagnosis code assignments? ...

Article Overview

This article covers the introduction of a diagnosis code for intraoperative floppy iris syndrome and discusses how the condition is described in relation to cataract surgery and medication exposure. It is relevant to ophthalmology, diagnosis coding, and medical record review because it shows where the condition fits within disorder categories and related external cause coding guidance. The page also includes a coding-oriented discussion of associated chapter placement, exclusions, and a sample case scenario.

Why This Topic Matters

It helps coders and clinicians identify the relevant diagnosis category for a surgery-related iris condition and understand the broader coding context around medication-related adverse effects.
