In simple words: This code indicates a score of zero on a stroke severity scale, meaning no signs of stroke-related problems.

National Institutes of Health Stroke Scale (NIHSS) score 0. Code first the type of cerebral infarction (I63.-) if applicable.

Example 1: A 60-year-old patient presents to the emergency department with transient symptoms concerning for stroke, such as brief unilateral weakness and slurred speech. After a thorough neurological examination and imaging studies, the physician determines the NIHSS score to be 0, indicating a transient ischemic attack (TIA) or stroke mimic. The code is useful for documentation and tracking of TIA or similar events where initial symptoms resolve completely., A patient arrives at the hospital with suspected stroke symptoms. Upon evaluation using the NIHSS, the patient scores a 0, indicating no neurological deficits. Further investigation reveals the symptoms are due to a different medical condition, such as hypoglycemia or migraine. In this case, R29.700 helps differentiate stroke mimics from actual strokes and aids in proper diagnosis., A patient with a history of stroke undergoes regular neurological assessments using the NIHSS. During one such assessment, the patient receives a score of 0. This indicates a positive outcome in stroke recovery and the absence of residual neurological deficits.

Documentation should include a detailed neurological examination record, results of imaging studies (CT, MRI), and the NIHSS assessment form completed by a qualified healthcare professional. Any other relevant clinical findings and differential diagnoses considered should also be documented.

** The NIHSS is a standardized tool used to evaluate the severity of stroke symptoms.A score of 0 indicates the absence of neurological deficits. If any neurological deficit is present, a different NIHSS code reflecting the appropriate score should be used.
