About coding primary purpura
The ICD-10-CM code for primary purpura is D69.49 (Other primary thrombocytopenia).
Within D69.4, choose D69.49 (Other primary thrombocytopenia) only when documentation doesn't support a more specific option: Evans syndrome (D69.41) and congenital and hereditary thrombocytopenia purpura (D69.42).
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.
