ICD-10 Code E50.2 – Vitamin A deficiency with corneal xerosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E50.2 – Vitamin A deficiency with corneal xerosis
What it is
E50.2 identifies vitamin A deficiency when it has caused corneal xerosis, a drying of the cornea. Use it when documentation links the deficiency to this specific eye finding.
Clinical signs
Clinical features may include dry, dull, or hazy corneal appearance and other signs of vitamin A deficiency. Clinical features vary; refer to documentation.
When to use this code
Use E50.2 when the record clearly states vitamin A deficiency with corneal xerosis or equivalent wording. It also applies when the clinician documents corneal dryness due to vitamin A deficiency. If the eye finding is present but the cause is not stated, check documentation.
Do not use for
Do not use this code for vitamin A deficiency without corneal involvement, or for corneal dryness from another cause. Check documentation if the record only says xerosis or dry eye.
Coding tip
Link the deficiency and corneal xerosis in the chart before assigning E50.2.
