Rupture in Descemet's membrane, right eye

This code signifies a tear or break in Descemet's membrane, the innermost layer of the corneal stroma, specifically affecting the right eye. Such a rupture can lead to corneal edema and vision impairment due to fluid accumulation within the cornea.

Use this code when documentation clearly indicates a diagnosis of Descemet's membrane rupture in the patient's right eye. This condition is often associated with corneal hydrops, trauma, or congenital anomalies like congenital glaucoma. Supporting documentation should include ophthalmological examination findings detailing the rupture.

• Ensure laterality is accurately documented and coded; this code is specific to the right eye.
• Distinguish from other corneal disorders, such as corneal edema or bullous keratopathy, unless the rupture is the underlying cause.
• Consider sequencing this code with other codes for the underlying cause or associated conditions, such as corneal hydrops (H18.2X) if present.
