About coding Leukoerythroblastosis
The ICD-10-CM code for Leukoerythroblastosis is D75.9 (Disease of blood and blood-forming organs, unspecified).
Within D75, choose D75.9 (Disease of blood and blood-forming organs, unspecified) only when documentation doesn't support a more specific option: familial erythrocytosis (D75.0), secondary polycythemia (D75.1), other specified diseases of blood and blood-forming organs (D75.8) and glucose-6-phosphate dehydrogenase (G6PD) deficiency without anemia (D75.A).
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.
