ICD-10 Code H18.441 – Keratomalacia, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H18.441 – Keratomalacia, right eye
What it is
Keratomalacia is softening and breakdown of the cornea in the right eye. This code identifies the condition as affecting only the right eye, so you should not use it for bilateral or unspecified eye disease.
Clinical signs
Typical findings include corneal clouding, ulceration, or melting with reduced transparency. Clinical features vary; refer to documentation for laterality, severity, and whether the cornea is actively thinning or perforated.
When to use this code
Use H18.441 when the record specifically documents keratomalacia in the right eye. This is appropriate when the clinician names corneal softening or corneal melting and clearly links it to the right eye. If the note only says corneal disease, check documentation before coding.
Do not use for
Do not use this code for keratomalacia of the left eye, both eyes, or an unspecified eye. Also avoid it when the documentation describes another corneal disorder without confirming keratomalacia.
Coding tip
Verify laterality in the ophthalmology note before assigning H18.441.
