AHA Coding Clinic® for ICD-9 - 2011 Issue 4; VOLUMES 1 & 2 NEW/REVISED CODES
Vitreomacular Adhesion
Effective October 1, 2011, a unique code for vitreomacular adhesion (379.27) has been created. Although vitreomacular adhesion is not a new condition, from a healthcare perspective, there is a need to track this discrete and potentially sight-threatening condition, understand its true prevalence, and identify it separately from other traction disorders as well as associated or downstream conditions. Vitreomacular adhesion (VMA) is a condition affecting the macula, a small portion of the retina, which is important for central vision. VMA may lead to visual impairment or blindness and a variety of complications with similar symptoms. It occurs as a...

Article Overview
This article covers vitreomacular adhesion as a distinct eye condition, why it was assigned a separate diagnosis code, and how it relates to other vitreous and macular disorders. It is relevant to ophthalmology, medical coding, and health information professionals who need to understand the condition, its associated findings, and the broad coding context discussed in the article.
Why This Topic Matters
The article helps readers recognize a specific retinal-vitreous condition that can affect central vision and may be associated with other eye diseases. It matters because the condition is identified separately for tracking and coding purposes, and the article places that distinction in the context of related diagnoses and a clinical scenario.
Article Sections
-
Overview of vitreomacular adhesion
Introduces the condition, why it is tracked separately, and the general clinical and coding context surrounding it.
-
Pathophysiology and related eye conditions
Describes how the condition develops and discusses related retinal and vitreous disorders in broad terms.
-
Eye anatomy and visual impact
Reviews the relevant anatomy of the macula, fovea, and vitreous body and explains why changes in these structures affect vision.
-
Development of vitreomacular traction
Explains how adhesion can persist after vitreous changes and how this can be associated with traction at the macula.
-
Coding context and clinical example
Presents the coding classification context and includes an example scenario involving diagnosis and procedure coding.
