What This Code Means
D69.5 is the ICD-10-CM diagnosis code for secondary thrombocytopenia. D69.5 sits in the ICD-10-CM chapter for diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism (d50-d89), within the section covering coagulation defects, purpura and other hemorrhagic conditions (d65-d69).
Header codes like D69.5 cannot be reported on claims directly; they organize child codes that share clinical context. Coders should select the billable child code that matches the documented presentation and then verify its current source-backed HCC mapping. Do not infer a child code or risk adjustment value from the header alone.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for D69.5 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
