Hyphema, right eye

This code signifies the presence of blood in the anterior chamber of the right eye, a condition known as hyphema. This accumulation of blood typically occurs between the cornea and the iris, often resulting from trauma or spontaneous bleeding.

Use this code when documentation clearly indicates a diagnosis of hyphema affecting the right eye. This is commonly seen following ocular trauma, but can also occur with certain medical conditions like bleeding disorders or neovascularization. Documentation should specify the affected eye.

• Always confirm laterality; separate codes exist for the left eye (H21.02) and bilateral involvement (H21.03).
• If the hyphema is traumatic, sequence the appropriate external cause code (e.g., W50-Y38) and injury code (e.g., S05.11XA) first, followed by this code.
• Distinguish from vitreous hemorrhage (H43.1-), which involves bleeding in the posterior chamber.
