ICD-10 code for hemolytic anemia

The ICD-10-CM code for hemolytic anemia is D58.9 (Hereditary hemolytic anemia, unspecified). The official index lists 56 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on D58.9.

Within D58, choose D58.9 (Hereditary hemolytic anemia, unspecified) only when documentation doesn't support a more specific option: hereditary spherocytosis (D58.0), hereditary elliptocytosis (D58.1), other hemoglobinopathies (D58.2) and other specified hereditary hemolytic anemias (D58.8).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

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.
