ICD-10 Code E64.1 – Sequelae of vitamin A deficiency (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E64.1 – Sequelae of vitamin A deficiency
What it is
E64.1 identifies lasting effects left after vitamin A deficiency has occurred. Use it when the current problem is a residual condition, not the active deficiency itself.
Clinical signs
Clinical features vary; refer to documentation. Residual findings may include persistent eye-related changes or other documented consequences of prior vitamin A deficiency.
When to use this code
Use E64.1 when the record clearly states a sequela, late effect, or residual condition due to past vitamin A deficiency. Code the remaining condition when it is being treated or evaluated now, and document the prior deficiency if supported.
Do not use for
Do not use this code for active vitamin A deficiency without sequelae. If the chart does not link the current condition to prior deficiency, check documentation.
Coding tip
Look for explicit wording such as “sequela,” “late effect,” or “residual of vitamin A deficiency” before assigning E64.1.
