About I69.9

I69.9 is the ICD-10-CM diagnosis code for sequelae of unspecified cerebrovascular diseases. It belongs to category I69 (sequelae of cerebrovascular disease), 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 8 subcodes must be used instead.

Within I69, choose I69.9 (unspecified cerebrovascular diseases) only when documentation doesn't support a more specific option: nontraumatic subarachnoid hemorrhage (I69.0), nontraumatic intracerebral hemorrhage (I69.1), other nontraumatic intracranial hemorrhage (I69.2), cerebral infarction (I69.3) and other cerebrovascular diseases (I69.8).

To report this condition, pick the subcode that matches the documentation: I69.90 (disease), I69.91 (disease), I69.92 (disease), I69.93 (disease), I69.94 (disease), I69.95 (disease), I69.96 (disease) and I69.99 (disease).

Don't report I69.9 together with the conditions in its Excludes1 note: sequelae of stroke (I69.3) and sequelae of traumatic intracranial injury (S06.-).

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