Final answer:
The ICD-10 code for a patient admitted for workup of normal pressure hydrocephalus because of ataxic gait is G80.9 (Cerebral palsy, unspecified).
Step-by-step explanation:
The ICD-10 code for a patient admitted for workup of normal pressure hydrocephalus because of ataxic gait would be G80.9 (Cerebral palsy, unspecified).
ICD-10 stands for International Classification of Diseases, Tenth Revision, which is a medical classification system used to classify and code diagnoses and procedures.
In this case, the ataxic gait is the symptom that led to the workup, and the ruling out of normal pressure hydrocephalus points toward a diagnosis of cerebral palsy, an umbrella term for a group of neurological disorders affecting movement and coordination.
