ICD-10 Code H20.051 – Hypopyon, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H20.051 – Hypopyon, right eye
What it is
H20.051 identifies hypopyon in the right eye, meaning a visible layering of white blood cells or pus in the anterior chamber. Use it when the finding is documented specifically in the right eye.
Clinical signs
Typical findings include a white or yellow fluid level behind the cornea, often with eye pain, redness, and light sensitivity. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents hypopyon limited to the right eye, whether as the main diagnosis or an associated finding. It may appear with inflammatory or infectious eye conditions, but you should code only what is documented.
Do not use for
Do not use this code for hypopyon in the left eye or bilateral involvement. If the record does not specify the eye or the diagnosis is uncertain, check documentation.
Coding tip
Always confirm laterality in the note before assigning H20.051.
