A41 vs P36
A41 (Other sepsis) compared with P36 (Bacterial sepsis of newborn), 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 P36: “neonatal (P36.-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
