Z22.3Carrier of other specified bacterial diseases

Z22.3 is the ICD-10-CM diagnosis code for carrier of other specified bacterial diseases. It belongs to category Z22 (carrier of infectious disease), block Z20-Z29 (persons with potential health hazards related to communicable diseases) 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 6 subcodes must be used instead.

Within Z22, choose Z22.3 (Carrier of other specified bacterial diseases) only when documentation doesn't support a more specific option: carrier of typhoid (Z22.0), carrier of other intestinal infectious diseases (Z22.1), carrier of diphtheria (Z22.2), carrier of infections with a predominantly sexual mode of transmission (Z22.4), carrier of human T-lymphotropic virus type-1 [HTLV-1] infection (Z22.6), latent tuberculosis (Z22.7), carrier of other infectious diseases (Z22.8) and unspecified (Z22.9).

To report this condition, pick the subcode that matches the documentation: Z22.31 (meningococci), Z22.32 (staphylococci), Z22.33 (streptococci), Z22.34 (baumannii), Z22.35 (Enterobacterales) and Z22.39 (diseases).

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