ICD-10 code for graft-versus-host disease

The ICD-10-CM code for graft-versus-host disease is D89.813 (Graft-versus-host disease, unspecified). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on D89.813.

Within D89.81, choose D89.813 (unspecified) only when documentation doesn't support a more specific option: acute graft-versus-host disease (D89.810), chronic graft-versus-host disease (D89.811) and acute on chronic graft-versus-host disease (D89.812).

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.
