AHA Coding Clinic® for ICD-9 - 2007 Issue 4; VOLUMES 1 AND 2 NEW/REVISED CODES
Intraoperative Floppy Iris Syndrome
Effective October 1, 2007, code 364.81, Intraoperative floppy iris syndrome, has been created for intraoperative floppy iris syndrome (IFIS). IFIS is a newly identified condition that occurs during cataract surgery. It is characterized by loss of muscle tone in the iris that is most commonly associated with an alpha-1 blocker (adrenoreceptor antagonist). The alpha-1 blocker is widely prescribed for the treatment of benign prostatic hyperplasia in men and urinary retention in women. As it is important that the pupil remain stable and dilated during cataract surgery, IFIS increases the risk of posterior capsular rupture and other surgical complications...

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.
Article Sections
-
Clinical overview of intraoperative floppy iris syndrome
Introduces the condition, its relationship to cataract surgery, and the general clinical context in which it is seen. The section also notes why the condition is significant in surgical care.
-
Coding placement and related diagnosis categories
Summarizes where the condition falls within the disorder classification and identifies related surrounding categories. It also references exclusion notes and an external cause code area.
-
Sample case and diagnosis coding question
Presents a short case scenario involving cataract surgery and medication exposure, followed by a coding question. The example is used to illustrate the article’s coding context.
