Z13.858

Encounter for screening for other nervous system disorders

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015
LAST UPDATED09/12/2025

Code Description

ICD-10 Z13.858 is a billable code used to indicate a diagnosis of encounter for screening for other nervous system disorders.

Key Diagnostic Point:

Z13.858 is used to indicate an encounter for screening for various nervous system disorders that are not specifically classified elsewhere. This code is essential in preventive care, as it allows healthcare providers to identify potential neurological issues early, facilitating timely intervention. Factors influencing health status, such as socioeconomic status, access to healthcare, and education, play a critical role in the effectiveness of these screenings. Social determinants of health, including living conditions and community resources, can impact the prevalence and management of nervous system disorders. Preventive screenings can help mitigate risks associated with these disorders, leading to improved health outcomes. Documentation must reflect the reason for the screening, any relevant patient history, and the results of the screening to ensure accurate coding and reimbursement.
