About Z22.32

Z22.32 is the ICD-10-CM diagnosis code for carrier of bacterial disease due to staphylococci. 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 2 subcodes must be used instead.

Within Z22.3 (carrier of other specified bacterial diseases), Z22.32 is specifically for carrier of bacterial disease due to staphylococci. Related codes cover bacterial disease due to meningococci (Z22.31), bacterial disease due to streptococci (Z22.33), Acinetobacter baumannii (Z22.34), Enterobacterales (Z22.35) and other specified bacterial diseases (Z22.39).

To report this condition, pick the subcode that matches the documentation: Z22.321 (aureus) and Z22.322 (aureus).

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