ICD-10 Code H21.02 – Hyphema, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H21.02 – Hyphema, left eye
What it is
H21.02 identifies blood in the anterior chamber of the left eye. Use it when documentation specifies a hyphema affecting only the left eye.
Clinical signs
Typical findings include visible blood layering in the front of the eye, blurred vision, eye pain, and light sensitivity. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents hyphema of the left eye, including traumatic or nontraumatic cases if laterality is stated. It is appropriate when the record clearly identifies the left eye and does not describe both eyes or an unspecified eye.
Do not use for
Do not use it for hyphema of the right eye, bilateral hyphema, or unspecified eye involvement. Check documentation if the note only says “hyphema” without laterality.
Coding tip
Confirm laterality from the assessment or ophthalmology note before assigning H21.02.
