Iridodialysis, left eye

This code describes a complete or partial separation of the iris from its attachment to the ciliary body in the left eye. This detachment can result in a D-shaped pupil, monocular diplopia, and photophobia due to uncontrolled light entry.

Use this code when documentation specifies iridodialysis affecting the left eye, typically following blunt ocular trauma, surgical complications, or rarely, spontaneously. Supporting documentation should clearly indicate the laterality of the condition.

• Always confirm laterality (left eye) from the physician's documentation.
• Distinguish from other iris disorders like iris atrophy or synechiae.
• Consider an external cause code (V00-Y99) if the iridodialysis is trauma-induced.
