ICD-10 Code D64.89 – Other specified anemias (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D64.89 – Other specified anemias
What it is
D64.89 is used for anemia that is documented but does not fit a more specific ICD-10 category. It captures other named or described anemias when the record supports them and no better code is available.
Clinical signs
Clinical features vary; refer to documentation. Anemia may be described by fatigue, pallor, weakness, or reduced oxygen-carrying capacity, but the key point is the provider’s specific diagnosis.
When to use this code
Use D64.89 when the clinician identifies an anemia that is not otherwise classified in ICD-10 and the chart does not support a more specific code. It is appropriate for documented “other specified anemia” or a clearly named anemia that lacks its own code. Check documentation if the cause or type is uncertain.
Do not use for
Do not use this code when a more specific anemia code applies, such as iron deficiency, vitamin deficiency, hemolytic, or aplastic anemia. Also avoid it if the record only says “anemia” without further detail.
Coding tip
Code the most specific anemia type documented, and use D64.89 only after confirming no more precise ICD-10 option fits.
