About I67.8

I67.8 is the ICD-10-CM diagnosis code for other specified cerebrovascular diseases. It belongs to category I67 (other cerebrovascular diseases), block I60-I69 (cerebrovascular diseases) and chapter 9 (diseases of the circulatory system). It is a header code, so it can't be reported by itself; one of its 6 subcodes must be used instead.

Within I67, choose I67.8 (Other specified cerebrovascular diseases) only when documentation doesn't support a more specific option: dissection of cerebral arteries, nonruptured (I67.0), cerebral aneurysm, nonruptured (I67.1), cerebral atherosclerosis (I67.2), progressive vascular leukoencephalopathy (I67.3), hypertensive encephalopathy (I67.4), Moyamoya disease (I67.5), nonpyogenic thrombosis of intracranial venous system (I67.6), cerebral arteritis, not elsewhere classified (I67.7) and 1 more.

To report this condition, pick the subcode that matches the documentation: I67.81 (insufficiency), I67.82 (ischemia), I67.83 (syndrome), I67.84 (vasoconstriction), I67.85 (diseases) and I67.89 (disease).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
