NIHSS score 26

This code indicates a National Institutes of Health Stroke Scale (NIHSS) score of 26, reflecting a severe neurological deficit typically observed in patients experiencing an acute ischemic stroke. The NIHSS is a standardized tool used to quantify stroke-related neurological impairment across various domains, including consciousness, motor function, sensation, and language.

Assign this code when documentation explicitly states an NIHSS score of 26, usually following an acute stroke event. This score signifies profound neurological impairment, often associated with significant disability and poor prognosis. It is crucial for tracking stroke severity and guiding treatment decisions.

• Always ensure the NIHSS score is clearly documented by the physician or qualified healthcare professional.
• Do not confuse this specific score with other NIHSS scores; each score has a unique code.
• Sequence this code after the primary diagnosis code for the acute stroke (e.g., I63.x).
