Facial weakness following ntrm subarachnoid hemorrhage

This code signifies the presence of facial muscle weakness that has developed as a direct consequence or sequela of a subarachnoid hemorrhage (SAH) that was not caused by trauma. It indicates a neurological deficit affecting the facial nerves, resulting from the previous intracranial bleeding.

Apply this code when documentation explicitly links facial weakness to a prior nontraumatic subarachnoid hemorrhage. This typically occurs in the post-acute or chronic phase of recovery. Supporting documentation should include a confirmed diagnosis of nontraumatic SAH and a clear assessment of residual facial weakness.

• Always sequence this code after the code for the nontraumatic subarachnoid hemorrhage (I60.-) if the SAH is still being treated or monitored.
• Ensure the documentation specifies "nontraumatic" SAH; otherwise, a different category for traumatic sequelae would be appropriate.
• Do not use this code for acute facial weakness occurring during the initial SAH event; this code is for residual or late-onset weakness.
