Chapter 3: Diseases of the Blood or Blood-Forming Organs
ICD-11 to ICD-10 crosswalk mappings for codes 3A00-3C9Z
80 ICD-11 codes in this chapter have ICD-10 crosswalk mappings from the WHO.
Covers anemias (nutritional, hemolytic, aplastic), coagulation defects, purpura, and other disorders of blood and blood-forming organs. ICD-11 separates blood diseases from immune disorders, providing clearer classification for hematological conditions.
