ICD-10 Code I69.86 – Other paralytic syndrome following other cerebrovascular disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.86 – Other paralytic syndrome following other cerebrovascular disease
What it is
I69.86 identifies residual paralysis or weakness that remains after a cerebrovascular disease other than stroke. Use it for lasting neurologic deficits caused by a prior vascular brain event, not for the acute episode itself.
Clinical signs
Common findings include persistent weakness, reduced movement, or paralysis affecting one or more limbs or body regions. Clinical features vary; refer to documentation for the exact neurologic deficit and laterality, if stated.
When to use this code
Use this code when the record clearly documents a past cerebrovascular disease with ongoing paralytic syndrome as a sequela. It is appropriate for follow-up visits when the residual deficit is the reason for care or is still being monitored.
Do not use it for an acute cerebrovascular event, and do not assume the deficit is current without documentation. If the note only says “history of CVA” or “weakness,” check documentation before assigning this code.
Do not use for
Do not use for acute stroke, transient ischemic attack, or nonspecific weakness without a documented paralytic sequela. Also avoid it when the paralysis is due to another cause, such as trauma or neuropathy.
Coding tip
Link the residual paralysis to the prior cerebrovascular disease in the chart, and code any documented laterality or dominant/nondominant detail separately when supported.
