About coding platelets decrease
The ICD-10-CM code for platelets decrease is D69.6 (Thrombocytopenia, unspecified).
Within D69, choose D69.6 (Thrombocytopenia, unspecified) only when documentation doesn't support a more specific option: allergic purpura (D69.0), qualitative platelet defects (D69.1), other nonthrombocytopenic purpura (D69.2), immune thrombocytopenic purpura (D69.3), other primary thrombocytopenia (D69.4), secondary thrombocytopenia (D69.5), other specified hemorrhagic conditions (D69.8) and hemorrhagic condition, unspecified (D69.9).
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 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.
