About coding allergic vasculitis
The ICD-10-CM code for allergic vasculitis is D69.0 (Allergic purpura).
Within D69 (purpura and other hemorrhagic conditions), D69.0 is specifically for allergic purpura. Related codes cover qualitative platelet defects (D69.1), 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).
Don't report D69.0 together with the conditions in its Excludes1 note: thrombocytopenic hemorrhagic purpura (D69.3).
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.
Don't confuse with (Excludes1 for D69.0)
- thrombocytopenic hemorrhagic purpura (D69.3)
