About coding spherocytosis
The ICD-10-CM code for spherocytosis is D58.0 (Hereditary spherocytosis). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on D58.0.
Within D58 (other hereditary hemolytic anemias), D58.0 is specifically for hereditary spherocytosis. Related codes cover hereditary elliptocytosis (D58.1), other hemoglobinopathies (D58.2), other specified hereditary hemolytic anemias (D58.8) and hereditary hemolytic anemia, unspecified (D58.9).
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 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.
