ICD-10 code for thrombocytopenia
Confirmed by the official ICD-10-CM index entry “thrombocytopenia, thrombocytopenic”. Page updated September 29, 2026.
About coding thrombocytopenia
The ICD-10-CM code for thrombocytopenia is D69.6 (Thrombocytopenia, unspecified). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on D69.6.
It is also searched as low platelets.
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.
