Z13.85Encounter for screening for nervous system disorders

Z13.85 is the ICD-10-CM diagnosis code for encounter for screening for nervous system disorders. It belongs to category Z13 (encounter for screening for other diseases and disorders), block Z00-Z13 (persons encountering health services for examinations) and chapter 21 (factors influencing health status and contact with health services). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.

Within Z13.8 (encounter for screening for other specified diseases and disorders), Z13.85 is specifically for encounter for screening for nervous system disorders. Related codes cover digestive system disorders (Z13.81), musculoskeletal disorder (Z13.82), respiratory disorder NEC (Z13.83), dental disorders (Z13.84), disorder due to exposure to contaminants (Z13.88) and other disorder (Z13.89).

To report this condition, pick the subcode that matches the documentation: Z13.850 (injury) and Z13.858 (disorders).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
