Excludes1 — never code together
The conditions below can never be reported together with A41 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Code first
The underlying condition below must be sequenced before A41. A41 describes a manifestation and cannot be the principal or first-listed diagnosis.
- , if applicable, postprocedural sepsis (T81.44-)
- sepsis due to central venous catheter (T80.211-)
- sepsis during labor (O75.3)
- sepsis following abortion, ectopic or molar pregnancy (O03.37, O03.87, O04.87, O07.37, O08.82)
- sepsis following immunization (T88.0-)
- sepsis following infusion, transfusion or therapeutic injection (T80.22-, T80.29-)
Excludes2 — not included here
The conditions below are not part of A41, but a patient may have both at the same time. When documentation supports it, A41 and the excluded code may both be reported.
- sepsis (due to) (in) actinomycotic (A42.7)
- sepsis (due to) (in) anthrax (A22.7)
- sepsis (due to) (in) candidal (B37.7)
- sepsis (due to) (in) Erysipelothrix (A26.7)

Use additional code — inherited from Chapter 1
Report an additional code alongside A41 to fully describe the condition. A41 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 A41, but a patient may have both at the same time. When documentation supports it, A41 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.-)
