A40 vs A41

A40 (Streptococcal sepsis) compared with A41 (Other sepsis), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.

Can these codes be reported together?

No — do not report together. A41 carries an Excludes1 note covering A40: “streptococcal sepsis (A40.-)”

Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
