Recession of chamber angle, unspecified eye

This code describes a condition where the angle formed by the iris and cornea, which is crucial for aqueous humor drainage, has receded or widened due to trauma, but the specific eye affected is not documented. This anatomical change can impair fluid outflow from the eye, potentially leading to elevated intraocular pressure.

Use this code when documentation indicates a recession of the anterior chamber angle, typically a sequela of blunt ocular trauma, but the medical record does not specify whether the right or left eye is affected. This diagnosis is often made via gonioscopy, revealing a widened ciliary body band.

• Ensure documentation clearly states "unspecified eye" or lacks laterality for the angle recession.
• Do not use this code if the affected eye (right or left) is specified; instead, use the laterality-specific codes.
• Consider sequencing this code with an external cause code (V, W, X, Y codes) if the trauma leading to the recession is still being treated or is relevant to the current encounter.
