ICD-10 Code D52.0 – Dietary folate deficiency anemia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D52.0 – Dietary folate deficiency anemia
What it is
D52.0 identifies anemia caused by inadequate dietary folate intake. Use it when the record shows folate deficiency from poor nutrition, not from absorption problems or medication effects.
Clinical signs
Clinical features vary; refer to documentation. Common findings include anemia with symptoms such as fatigue, pallor, and weakness, and the chart may note evidence of folate deficiency.
When to use this code
Use D52.0 when the provider documents dietary folate deficiency as the cause of the anemia. It fits cases tied to insufficient intake, poor diet, or malnutrition when folate deficiency is specifically identified.
Assign this code only when the medical record supports a nutritional cause. If the cause is unclear, or another etiology is documented, check documentation before coding.
Do not use for
Do not use D52.0 for folate deficiency anemia due to malabsorption, drugs, or other non-dietary causes. Do not apply it when folate deficiency is not documented.
Coding tip
Look for explicit provider wording linking anemia to dietary folate deficiency before assigning D52.0.
