About coding platelets dysfunction
The ICD-10-CM code for platelets dysfunction is D69.19 (Other qualitative platelet defects).
Within D69.1, choose D69.19 (Other qualitative platelet defects) only when documentation doesn't support a more specific option: Glanzmann thrombasthenia (D69.11).
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 813 (Coagulation Disorders, relative weight 1.5257), 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.
