ICD-10 Code H16.051 – Mooren’s corneal ulcer, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H16.051 – Mooren’s corneal ulcer, right eye
What it is
H16.051 identifies Mooren’s corneal ulcer affecting the right eye. It refers to a painful peripheral corneal ulceration that is not due to trauma or another obvious cause.
Clinical signs
Typical findings include peripheral corneal ulceration, pain, redness, tearing, and possible photophobia. Clinical features vary; refer to documentation.
When to use this code
Use H16.051 when the provider documents Mooren’s corneal ulcer in the right eye. Apply it when the diagnosis is specific to the right eye and the record supports a corneal ulcer of this type.
Confirm laterality in the chart before coding. If the note only says corneal ulcer without specifying Mooren’s type, check documentation.
Do not use for
Do not use this code for corneal ulcers with a documented infectious, traumatic, or other specific cause. Do not use it when the eye is not identified as the right eye.
Coding tip
Code the laterality exactly as documented, and query the provider if Mooren’s ulcer is stated without eye laterality.
