Iridodialysis, bilateral

This code describes a complete or partial separation of the iris from its ciliary body attachment in both eyes. This detachment can result in a D-shaped pupil and may lead to monocular diplopia, glare, or photophobia due to light entering the eye through the defect.

Use this code when documentation clearly indicates iridodialysis affecting both the right and left eyes. This condition is often a sequela of blunt ocular trauma, but can also occur iatrogenically during intraocular surgery. Supporting documentation should include a physician's diagnosis and findings from an ophthalmologic examination.

• Ensure the documentation explicitly states "bilateral" or specifies iridodialysis in both eyes.
• Do not confuse this with other iris disorders like iris atrophy or synechiae; this code is specific to detachment from the ciliary body.
• Code any associated ocular trauma or surgical complications as primary diagnoses if they are the underlying cause.
