I69.99Other sequelae of unspecified cerebrovascular disease

I69.99 is the ICD-10-CM diagnosis code for other sequelae of unspecified cerebrovascular disease. 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 5 subcodes must be used instead.

Within I69.9, choose I69.99 (Other sequelae of unspecified cerebrovascular disease) only when documentation doesn't support a more specific option: unspecified sequelae of unspecified cerebrovascular disease (I69.90), cognitive deficits following unspecified cerebrovascular disease (I69.91), speech and language deficits following unspecified cerebrovascular disease (I69.92), monoplegia of upper limb following unspecified cerebrovascular disease (I69.93), monoplegia of lower limb following unspecified cerebrovascular disease (I69.94), hemiplegia and hemiparesis following unspecified cerebrovascular disease (I69.95) and other paralytic syndrome following unspecified cerebrovascular disease (I69.96).

To report this condition, pick the subcode that matches the documentation: I69.990 (disease), I69.991 (disease), I69.992 (disease), I69.993 (disease) and I69.998 (disease).

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