ICD-10 Code H18.44 – Keratomalacia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H18.44 – Keratomalacia
What it is
Keratomalacia is softening and degeneration of the cornea, usually from severe vitamin A deficiency. It can progress quickly and threaten vision if not recognized.
Clinical signs
Findings may include corneal clouding, dryness, ulceration, and soft, necrotic corneal tissue. Clinical features vary; refer to documentation.
When to use this code
Use H18.44 when the provider documents keratomalacia or corneal softening due to vitamin A deficiency. It may also apply when the record clearly links corneal degeneration to malnutrition or deficiency states. Code only when the diagnosis is established, not merely suspected.
Do not use for
Do not use this code for simple dry eye, corneal abrasion, or nonspecific keratitis without corneal softening. Check documentation if the note describes another corneal disorder.
Coding tip
Confirm that the provider names keratomalacia or documents corneal softening before assigning H18.44.
