ICD-10 code for Hypochromic anemia
From the official ICD-10-CM alphabetic index entry “Anemia (essential) (general) (hemoglobin deficiency) (infantile) (primary) (profound) › hypochromic (idiopathic) (microcytic) (normoblastic)”. Page updated September 29, 2026.
About coding Hypochromic anemia
The ICD-10-CM code for Hypochromic anemia is D50.9 (Iron deficiency anemia, unspecified). The official index lists 5 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on D50.9.
Within D50, choose D50.9 (unspecified) only when documentation doesn't support a more specific option: secondary to blood loss (chronic) (D50.0), Sideropenic dysphagia (D50.1) and other iron deficiency anemias (D50.8).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 811 (Red Blood Cell Disorders with MCC, relative weight 1.3988) and DRG 812 (Red Blood Cell Disorders without MCC, relative weight 0.9234), in MDC 16 (Diseases and Disorders of the Blood and Blood Forming Organs and Immunological Disorders), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
