Unspecified sequelae of other cerebrovascular disease

This code represents a long-term or residual effect stemming from a cerebrovascular event other than a stroke, such as a transient ischemic attack (TIA), cerebral aneurysm, or arteriovenous malformation (AVM), when the specific sequela is not documented. It indicates that a patient is experiencing ongoing health issues directly attributable to a past cerebrovascular disease, but the precise nature of these effects is not specified.

Use this code when documentation clearly links a current symptom or condition to a previous cerebrovascular disease (other than stroke) but does not provide enough detail to assign a more specific sequelae code. This is appropriate when the provider notes "sequelae of TIA" or "residual effects of cerebral aneurysm" without further elaboration on the specific deficit.

• Always attempt to query for a more specific sequela if possible, as this code indicates a lack of specificity.
• Do not use this code for sequelae of stroke; refer to the I69.3- category for those conditions.
• This code is typically sequenced after the acute cerebrovascular event has resolved and the patient is experiencing chronic, residual effects.
