ICD-10 Codes for Anemia
The provided evidence does not contain specific ICD-10 coding information for anemia. The clinical guidelines and research studies focus on the diagnosis, management, and validation of anemia coding systems rather than listing the actual codes themselves.
What the Evidence Shows
The research demonstrates that ICD-10 codes for anemia have significant limitations in accuracy 1, 2. A 2025 validation study found that ICD-10 diagnosis codes for antepartum anemia had only 30% sensitivity (missing 70% of cases) despite 91.8% specificity 1. Another study examining anemia codes showed 32.9% overall discordance between different coding sources 2.
Key Coding Considerations
For general anemia coding:
- ICD-10 codes exist in the D50-D64 range (based on standard ICD-10 classification)
- Specific codes depend on anemia type (iron deficiency, chronic disease, etc.)
- The evidence emphasizes that diagnosis should be based on laboratory values (hemoglobin, ferritin, transferrin saturation) rather than relying solely on coding 3
For specific anemia types mentioned in the evidence:
- Sickle cell anemia uses D57x codes, with D5700, D5701, D5702 for specific types and D571 for nonspecific cases 4
- Iron deficiency anemia requires confirmation with ferritin <15 μg/L (highly specific) or <45 μg/L in inflammatory conditions 3
Clinical Pitfall
Do not use ICD-10 codes alone to identify or diagnose anemia in clinical practice or research 1, 2. The low sensitivity means substantial underdiagnosis. Always confirm with laboratory values: hemoglobin levels, mean cell volume, ferritin, and transferrin saturation 3.
For accurate ICD-10 code assignment, consult your institution's coding department or the official ICD-10-CM manual, as the clinical evidence provided does not specify the complete coding structure.
