About coding ANCA positive vasculitis
The ICD-10-CM code for ANCA positive vasculitis is I77.82 (Antineutrophilic cytoplasmic antibody [ANCA] vasculitis).
Within I77.8 (other specified disorders of arteries and arterioles), I77.82 is specifically for Antineutrophilic cytoplasmic antibody [ANCA] vasculitis. Related codes cover aortic ectasia (I77.81) and other specified disorders of arteries and arterioles (I77.89).
The conditions in its Excludes2 note aren't part of I77.82, but may be coded alongside it if the patient has both: eosinophilic granulomatosis with polyangiitis (M30.1), granulomatosis with polyangiitis (M31.3-) and microscopic polyangiitis (M31.7).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
