In simple words: This code describes facial weakness or drooping that happens after a person has a problem with the blood vessels in their brain, like a stroke, but not including injuries to the head.

This code specifies a facial weakness or droop that occurs as a sequela of a cerebrovascular disease, excluding traumatic intracranial injury (S06.-) or sequelae of the same.It encompasses various cerebrovascular conditions like stroke, but not the initial event itself.

Example 1: A patient presents with persistent right-sided facial droop following a stroke six months prior. The droop was not present before the stroke., A patient experiences new onset facial weakness following a diagnosed cerebrovascular accident. The weakness is documented during a follow-up visit., A patient with a history of stroke reports difficulty controlling facial muscles on one side.This started weeks after the initial stroke event and has worsened gradually.

Documentation should include details about the cerebrovascular event, the onset and progression of facial weakness, neurological examination findings, and any associated symptoms.

** For aftercare related to cerebrovascular disease and facial weakness following the acute phase of illness, a Z code might also be applicable for long-term follow-up (e.g., Z86.73 - personal history of transient ischemic attack and related syndromes). The appropriate 7th character should be added to this code to indicate the encounter type (e.g., A for initial encounter, D for subsequent encounter, or S for sequela).
