ICD-10 Code D64 – Other anemias (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D64 – Other anemias
What it is
D64 is a category for anemias that do not fit a more specific ICD-10-CM code. Use it when documentation identifies an unspecified or other type of anemia and no narrower diagnosis is recorded.
Clinical signs
Clinical features vary; refer to documentation. Anemia is commonly described by reduced red blood cell mass or hemoglobin, with possible fatigue, pallor, weakness, or shortness of breath.
When to use this code
Use D64 when the provider documents “other anemia,” “unspecified anemia,” or a similar non-specific anemia diagnosis and no more precise code is available. It may also apply when the chart confirms anemia but does not identify a cause or subtype. Check documentation before assigning a more specific code.
Do not use for
Do not use D64 if the record supports a specific anemia type, such as iron deficiency, hemolytic, aplastic, or vitamin deficiency anemia. Also avoid it when the condition is only suspected or not documented as anemia.
Coding tip
Look for the underlying cause and the exact anemia type before defaulting to D64.
