D69.1Qualitative platelet defects

D69.1 is the ICD-10-CM diagnosis code for qualitative platelet defects. It belongs to category D69 (purpura and other hemorrhagic conditions), block D65-D69 (coagulation defects, purpura and other hemorrhagic conditions) and chapter 3 (diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.

Within D69 (purpura and other hemorrhagic conditions), D69.1 is specifically for qualitative platelet defects. Related codes cover allergic purpura (D69.0), other nonthrombocytopenic purpura (D69.2), immune thrombocytopenic purpura (D69.3), 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).

To report this condition, pick the subcode that matches the documentation: D69.11 (thrombasthenia) and D69.19 (defects).

Don't report D69.1 together with the conditions in its Excludes1 note: hemolytic-uremic syndrome (D59.3-).

The conditions in its Excludes2 note aren't part of D69.1, but may be coded alongside it if the patient has both: von Willebrand disease (D68.0-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2027 (expanded into subcodes).

Before ICD-10, this condition was coded in ICD-9-CM as 287.1 (qualitative platelet defects).
