Anterior synechiae (iris), unspecified eye

This code describes the abnormal adhesion of the iris to the posterior surface of the cornea, specifically in the anterior chamber of the eye. This condition can obstruct aqueous humor outflow, potentially leading to increased intraocular pressure. It represents an unspecified laterality, meaning the affected eye is not documented.

Use this code when the medical record clearly documents anterior synechiae of the iris, but the specific eye (right or left) is not specified. This diagnosis is often made during a slit-lamp examination. Documentation should indicate the presence of iris adhesions to the cornea.

• Do not use this code if the laterality (right or left eye) is documented; instead, select the appropriate laterality-specific code.
• Consider coding any underlying conditions causing the synechiae, such as uveitis or trauma, as primary diagnoses if applicable.
• Ensure documentation differentiates between anterior synechiae (iris to cornea) and posterior synechiae (iris to lens), as these are distinct conditions.
