NIHSS score 2

This code indicates a National Institutes of Health Stroke Scale (NIHSS) score of 2, reflecting a very minor neurological deficit often associated with a stroke or transient ischemic attack (TIA). The NIHSS is a standardized tool used to quantify the severity of neurological impairment.

Use this code when documentation explicitly states an NIHSS score of 2, typically in the context of acute cerebrovascular events. This score is often recorded during initial assessment or follow-up to track neurological status.

• Always ensure the NIHSS score is clearly documented by the clinician.
• This code should be sequenced after the primary diagnosis for the cerebrovascular event (e.g., ischemic stroke, TIA).
• Do not use this code if the NIHSS score is not explicitly stated as 2; use the unspecified code or the appropriate specific score.
