About coding hypereosinophilic HES syndrome
The ICD-10-CM code for hypereosinophilic HES syndrome is D72.119 (Hypereosinophilic syndrome [HES], unspecified). The official index lists 4 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on D72.119.
Within D72.11, choose D72.119 (unspecified) only when documentation doesn't support a more specific option: idiopathic hypereosinophilic syndrome [IHES] (D72.110), lymphocytic Variant Hypereosinophilic Syndrome [LHES] (D72.111) and other hypereosinophilic syndrome (D72.118).
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 814 (Reticuloendothelial and Immunity Disorders with MCC, relative weight 2.0729), DRG 815 (Reticuloendothelial and Immunity Disorders with CC, relative weight 1.0444) and DRG 816 (Reticuloendothelial and Immunity Disorders without CC/MCC, relative weight 0.7381), 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.
