Is A41 a billable ICD-10-CM code?

No. A41 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does A41 sit in the tabular list?

Certain infectious and parasitic diseases (A00-B99), in the block Other bacterial diseases (A30-A49).

What cannot be coded together with A41?

A41 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter.

A41 — Other sepsis

Non-billable headerICD-10-CM

A41 is a non-billable header ICD-10-CM code for other sepsis. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

bacteremia NOS (R78.81)
neonatal (P36.-)
puerperal sepsis (O85)
streptococcal sepsis (A40.-)

Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

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)
sepsis (due to) (in) extraintestinal yersiniosis (A28.2)
sepsis (due to) (in) gonococcal (A54.86)
sepsis (due to) (in) herpesviral (B00.7)
sepsis (due to) (in) listerial (A32.7)
sepsis (due to) (in) melioidosis (A24.1)
sepsis (due to) (in) meningococcal (A39.2-A39.4)
sepsis (due to) (in) plague (A20.7)
sepsis (due to) (in) tularemia (A21.7)
toxic shock syndrome (A48.3)

Code first

The underlying condition must be sequenced before this code.

, 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-)

Other codes that can never be billed with A41

These codes carry an Excludes1 note pointing at A41. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading A41 alone.

A40Streptococcal sepsis
Z16Resistance to antimicrobial drugs
A48.3Toxic shock syndrome

Risk adjustment

A41 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

The condition this code belongs to

Every code for the condition on one page, which one applies when, and the mistake coders make with it.

Code history

A41 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.

Code to one of these instead A41

8 child codes. Green means billable.
