I67Other cerebrovascular diseases

I67 is the ICD-10-CM diagnosis code for other cerebrovascular diseases. It belongs to 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 10 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: I67.0 (nonruptured), I67.1 (nonruptured), I67.2 (atherosclerosis), I67.3 (leukoencephalopathy), I67.4 (encephalopathy), I67.5 (disease), I67.6 (system), I67.7 (classified) and 2 more.

Don't report I67 together with the conditions in its Excludes1 note: Occlusion and stenosis of cerebral artery causing cerebral infarction (I63.3-I63.5-) and Occlusion and stenosis of precerebral artery causing cerebral infarction (I63.2-).

The conditions in its Excludes2 note aren't part of I67, but may be coded alongside it if the patient has both: sequelae of the listed conditions (I69.8).

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