Code Description

ICD-10 R29.711 is a billable code used to indicate a diagnosis of nihss score 11.

Key Diagnostic Point:

The NIHSS (National Institutes of Health Stroke Scale) score of 11 indicates a moderate stroke severity, reflecting significant neurological impairment. This score is derived from a comprehensive assessment of various neurological functions, including consciousness, language, motor skills, and sensory perception. Patients with a score of 11 may exhibit symptoms such as unilateral weakness, speech difficulties, and impaired coordination. Common causes of such neurological deficits include ischemic strokes, hemorrhagic strokes, or transient ischemic attacks (TIAs). The NIHSS is crucial for determining treatment options and predicting patient outcomes. Accurate scoring and documentation are essential for effective treatment planning and resource allocation in acute stroke management.
