Excludes1 — never code together
The conditions below can never be reported together with A92 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

Report an additional code alongside A92 to fully describe the condition. A92 is sequenced first.
- code to identify resistance to antimicrobial drugs (Z16.-)
