About coding idiopathic thrombocytopenic purpura
The ICD-10-CM code for idiopathic thrombocytopenic purpura is D69.3 (Immune thrombocytopenic purpura). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on D69.3.
Within D69 (purpura and other hemorrhagic conditions), D69.3 is specifically for immune thrombocytopenic purpura. Related codes cover allergic purpura (D69.0), qualitative platelet defects (D69.1), other nonthrombocytopenic purpura (D69.2), other primary thrombocytopenia (D69.4), secondary thrombocytopenia (D69.5), thrombocytopenia, unspecified (D69.6), other specified hemorrhagic conditions (D69.8) and hemorrhagic condition, unspecified (D69.9).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
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.
