ICD-10 code for arrest marrow

The ICD-10-CM code for arrest marrow is D61.9 (Aplastic anemia, unspecified).

Within D61, choose D61.9 (Aplastic anemia, unspecified) only when documentation doesn't support a more specific option: constitutional aplastic anemia (D61.0), drug-induced aplastic anemia (D61.1), aplastic anemia due to other external agents (D61.2), idiopathic aplastic anemia (D61.3) and other specified aplastic anemias and other bone marrow failure syndromes (D61.8).

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 808 (Major Hematological and Immunological Diagnoses Except Sickle Cell Crisis and Coagulation Disorders with MCC, relative weight 2.1705), DRG 809 (Major Hematological and Immunological Diagnoses Except Sickle Cell Crisis and Coagulation Disorders with CC, relative weight 1.2262) and DRG 810 (Major Hematological and Immunological Diagnoses Except Sickle Cell Crisis and Coagulation Disorders without CC/MCC, relative weight 1.075), 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.
