ICD-10 Code I69.992 – Facial weakness following unspecified cerebrovascular disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.992 – Facial weakness following unspecified cerebrovascular disease
What it is
This code identifies facial weakness that remains after an unspecified cerebrovascular disease, such as a prior stroke or other brain vessel event. Use it for residual weakness, not for the acute cerebrovascular episode.
Clinical signs
Clinical features vary; refer to documentation. Typical findings include reduced facial movement, asymmetry, drooping, or impaired facial expression documented as a residual effect of cerebrovascular disease.
When to use this code
Use this code when the record clearly links facial weakness to a past cerebrovascular disease and the acute event is no longer the focus of care. It is appropriate for follow-up visits when the weakness persists as a sequela. Check documentation if the cause, laterality, or acuity is unclear.
Do not use for
Do not use it for acute stroke, transient ischemic attack, or facial weakness from another cause such as Bell palsy or trauma. If the weakness is not documented as a cerebrovascular sequela, check documentation.
Coding tip
Confirm that the provider documents a causal link to prior cerebrovascular disease before assigning this sequela code.
