Anterior synechiae (iris), left eye

This code describes an abnormal adhesion of the iris to the posterior surface of the cornea, specifically affecting the left eye. This condition can obstruct aqueous humor outflow, potentially leading to increased intraocular pressure and glaucoma. It is often a sequela of inflammation, trauma, or surgery.

Use this code when documentation clearly indicates anterior synechiae involving the iris in the left eye. This diagnosis is typically made during a slit-lamp examination. Supporting documentation should specify the location (anterior) and the eye affected.

• Differentiate from posterior synechiae (iris adhering to the lens capsule), which has a different code.
• Always specify laterality (left, right, or bilateral) as indicated in the clinical record.
• Code any underlying cause, such as uveitis or trauma, as a primary diagnosis if applicable.
