ICD-10 codes for Anemia
Anemia is coded primarily under D64.9, D50.9, D53.9 in the ICD-10-CM (Clinical Modification) classification. Top-level categories include D50 (Iron deficiency anemia); D51 (Vitamin B12 deficiency anemia); D52 (Folate deficiency anemia); D53 (Other nutritional anemias). The 2025 ICD-10-CM code set includes 156 codes related to anemia, of which 127 are billable (specific enough to appear on a medical claim).
Anemia is a deficiency of red blood cells or hemoglobin. ICD-10-CM groups anemia codes under D50 to D64. The most commonly used codes include D64.9 for unspecified anemia, D50 codes for iron deficiency, D52 for folate deficiency, D51 for vitamin B12 deficiency, and D63 codes for anemia in other diseases.

What is the ICD-10 code for anemia?
The primary ICD-10-CM codes for anemia are D64.9, D50.9, D53.9. Across all sub-categories, 156 codes are grouped under anemia, with 127 marked as billable (specific enough for a medical claim).
How many ICD-10 codes are there for anemia?
There are 156 ICD-10-CM codes related to anemia. Of these, 127 are billable specific codes and 29 are non-billable header categories that organize the specific codes underneath them. Header codes cannot be reported on a claim by themselves.
Is there a billable ICD-10 code for anemia?
Yes. 127 of the 156 ICD-10-CM codes for anemia are billable. Common examples include D50.0 (Iron deficiency anemia secondary to blood loss (chronic)); D50.1 (Sideropenic dysphagia); D50.8 (Other iron deficiency anemias). Code to the highest level of specificity supported by the documentation.
Which anemia ICD-10 code should I use for billing?
The most commonly used billable codes for anemia include: D50.0 (Iron deficiency anemia secondary to blood loss (chronic)); D50.1 (Sideropenic dysphagia); D50.8 (Other iron deficiency anemias). The correct code depends on the documented clinical presentation, including any complications, episode (acute / chronic), and laterality where applicable. Always code to the highest level of specificity supported by the clinical documentation.
Is D64.9 a billable ICD-10 code?
Yes, D64.9 (Anemia, unspecified) is a billable / specific ICD-10-CM code that can be reported on insurance claims.
What are the SNOMED CT concepts for anemia?
The ICD-10 codes for anemia map to at least 25 SNOMED CT concepts. Examples of SNOMED CT concept IDs in this group include 234352004, 300980002, 413532003, 413533008, 724556004. SNOMED CT is a clinical terminology used in electronic health records; AutoICD's coding API returns SNOMED CT IDs alongside each ICD-10 code via the include_snomed=true flag.
What UMLS Concept Unique Identifiers (CUIs) cover anemia?
The ICD-10 codes for anemia are linked to at least 25 UMLS CUIs in the National Library of Medicine's Metathesaurus. Sample CUIs include C0002884, C0008272, C0162316, C0154286, C0032249. UMLS CUIs unify the same concept across SNOMED CT, ICD-10, ICD-11, RxNorm, MeSH, and dozens of other source vocabularies.
What are other names for anemia in ICD-10?
Anemia may also be referred to as: anemia, low hemoglobin, anemia of chronic disease, B12 deficiency anemia. The same ICD-10-CM codes apply regardless of which term appears in the clinical documentation. Synonyms are surfaced by AutoICD's NER pass and mapped to the canonical ICD-10 family above.
