I62Other and unspecified nontraumatic intracranial hemorrhage

I62 is the ICD-10-CM diagnosis code for other and unspecified nontraumatic intracranial hemorrhage. 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 3 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: I62.0 (hemorrhage), I62.1 (hemorrhage) and I62.9 (unspecified).

The conditions in its Excludes2 note aren't part of I62, but may be coded alongside it if the patient has both: sequelae of intracranial hemorrhage (I69.2).

Use an additional code, if known, to indicate National Institutes of Health Stroke Scale (NIHSS) score (R29.7-).

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