Hyphema, left eye

This code describes the presence of blood in the anterior chamber of the left eye, typically visible as a reddish fluid level between the cornea and the iris. This condition often results from trauma, but can also be spontaneous due to underlying medical conditions.

Use this code when documentation clearly indicates a diagnosis of hyphema affecting the left eye. This diagnosis is typically made during an ophthalmologic examination following an injury or when a patient presents with sudden vision changes or eye pain.

• Always specify laterality; do not use unspecified codes if the left eye is documented.
• Code any underlying cause of the hyphema (e.g., trauma, bleeding disorder) as a primary or secondary diagnosis.
• Distinguish from vitreous hemorrhage (H43.1-), which involves bleeding in the posterior chamber.
