Excludes1 — never code together
The conditions below can never be reported together with A75 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- rickettsiosis due to Ehrlichia sennetsu (A79.81)
Use additional code — inherited from Chapter 1
Report an additional code alongside A75 to fully describe the condition. A75 is sequenced first.
- code to identify resistance to antimicrobial drugs (Z16.-)
Excludes2 — not included here — inherited from Chapter 1
The conditions below are not part of A75, but a patient may have both at the same time. When documentation supports it, A75 and the excluded code may both be reported.
- carrier or suspected carrier of infectious disease (Z22.-)
- certain localized infections - see body system-related chapters
- infectious and parasitic diseases complicating pregnancy, childbirth and the puerperium (O98.-)
- infectious and parasitic diseases specific to the perinatal period (P35-P39)
