ICD-10 Code E50.9 – Vitamin A deficiency, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E50.9 – Vitamin A deficiency, unspecified
What it is
E50.9 identifies vitamin A deficiency when the record confirms deficiency but does not specify the type or cause. Use it for a general diagnosis of low vitamin A status without further detail.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings may include night blindness, dry eyes, or other signs of impaired vision and mucous membrane changes.
When to use this code
Use E50.9 when the provider documents vitamin A deficiency and no more specific subtype is stated. It also fits when the chart lacks enough detail to code a more specific deficiency category. Check documentation if the cause, severity, or associated eye findings are described.
Do not use for
Do not use this code if the record specifies a different vitamin deficiency or a more precise vitamin A deficiency code. Do not assign it when vitamin A status is normal or only suspected.
Coding tip
If the note mentions eye findings, malnutrition, or a known cause, look for a more specific code before defaulting to E50.9.
