ICD-10 Code H16.331 – Sclerosing keratitis, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H16.331 – Sclerosing keratitis, right eye
What it is
H16.331 identifies sclerosing keratitis affecting the right eye. It refers to a corneal inflammatory condition with progressive stromal scarring or sclerosis that can reduce corneal clarity.
Clinical signs
Typical findings include corneal opacity, stromal haze, and signs of chronic inflammation in the right eye. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents sclerosing keratitis specifically in the right eye. It is appropriate for ophthalmology notes, problem lists, or encounter diagnoses that clearly localize the condition to the right eye. If laterality is not documented, check documentation.
Do not use for
Do not use this code for keratitis in the left eye, both eyes, or unspecified eye. Avoid it when the record describes another corneal disorder without sclerosing keratitis.
Coding tip
Confirm laterality in the assessment or impression before assigning H16.331.
