What D64 covers · when clinicians use it
ICD-10 code D64 identifies Other anemias in the U.S. ICD-10-CM clinical and billing record set. It sits within the Blood & Blood-forming Organs chapter (D50–D89), the section that groups related diagnoses so providers, payers, and public-health agencies report them consistently. Clinicians and medical coders apply D64 when an encounter's findings match the Other anemias description, attaching it to the patient record so downstream insurance claims, payer audits, quality reporting, and epidemiological surveillance all reference the same standardized diagnosis. The ICD-10-CM is maintained by the Centers for Medicare & Medicaid Services and the CDC's National Center for Health Statistics, with an updated official code set released each U.S. fiscal year — always verify D64 against the current CMS/CDC release and your payer's documentation guidance before final use. This page summarizes documentation context for D64 and is a coding reference, not clinical, diagnostic, or billing advice.
D64 refers to Other anemias, a group of anemias that do not fall under typical nutritional or hemolytic categories. These include red cell aplasia, marrow failure, bleeding-induced anemia, and anemia related to chronic disease. Each has distinct etiologies and management strategies but shares a core disruption in red blood cell production or survival.
Symptoms
- Fatigue – From low hemoglobin and oxygen delivery
- Pallor – Especially visible in the skin and mucosa
- Shortness of breath – Particularly on exertion
- Rapid heartbeat – As the body compensates for anemia
- Weakness or dizziness – From low red cell count
- Bleeding symptoms – If associated with marrow failure
- Delayed healing or chronic illness signs – In anemia of chronic disease
Diagnosis
Diagnosis of Other anemias requires complete blood count (CBC), reticulocyte count, bone marrow biopsy (in marrow failure syndromes), iron studies, and inflammatory markers. Underlying causes such as chronic disease, hemorrhage, or autoimmune conditions must be identified for effective treatment.
ICD10 Code Usage
ICD10 code D64 is widely used in hematology, internal medicine, oncology, and critical care. It helps document non-nutritional and non-hereditary anemias in EHRs, insurance claims, and public health records, aiding clinical and financial continuity of care.
Related Codes
- D60 – Acquired pure red cell aplasia [erythroblastopenia]
- D61 – Other aplastic anemias and other bone marrow failure syndromes
- D62 – Acute posthemorrhagic anemia
- D63 – Anemia in chronic diseases classified elsewhere
FAQs
Q1: What is ICD10 code D64?
A: It represents Other anemias, used to document non-nutritional, acquired, or secondary forms of anemia in clinical practice.
Q2: What are the main causes?
A: Blood loss, chronic diseases (e.g., cancer, kidney disease), autoimmune suppression of marrow, or unknown marrow failure mechanisms.
Q3: Are these anemias reversible?
A: Some are treatable or manageable, especially if the underlying cause is addressed. Others may require lifelong monitoring.
Q4: How are they treated?
A: Blood transfusions, immunosuppressants, erythropoietin, or treatment of the root condition (e.g., inflammation, infection).
Q5: Who manages these conditions?
A: Hematologists, internists, nephrologists, or oncologists depending on the cause and severity.
Conclusion
ICD10 code D64 enables clear classification and tracking of Other anemias. It supports personalized management, enables coding precision, and ensures that patients receive targeted evaluation and therapies based on the specific type of anemia.
