About A41.5
A41.5 is the ICD-10-CM diagnosis code for sepsis due to other Gram-negative organisms. It belongs to category A41 (other sepsis), block A30-A49 (other bacterial diseases) and chapter 1 (certain infectious and parasitic diseases). It is a header code, so it can't be reported by itself; one of its 6 subcodes must be used instead.
Within A41, choose A41.5 (Sepsis due to other Gram-negative organisms) only when documentation doesn't support a more specific option: sepsis due to Staphylococcus aureus (A41.0), sepsis due to other specified staphylococcus (A41.1), sepsis due to unspecified staphylococcus (A41.2), sepsis due to Hemophilus influenzae (A41.3), sepsis due to anaerobes (A41.4), other specified sepsis (A41.8) and sepsis, unspecified organism (A41.9).
To report this condition, pick the subcode that matches the documentation: A41.50 (unspecified), A41.51 (coli]), A41.52 (pseudomonas), A41.53 (serratia), A41.54 (baumannii) and A41.59 (sepsis).
Code first: , 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) and 2 more.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
