Is A41.0 a billable ICD-10-CM code?

No. A41.0 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does A41.0 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 A41.0?

A41.0 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter. Some are written on the categories above A41.0 (A41) and apply to it just the same.

A41.0 — Sepsis due to Staphylococcus aureus

Non-billable headerICD-10-CM

A41.0 is a non-billable header ICD-10-CM code for sepsis due to staphylococcus aureus. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 inherited from the categories above A41.0

These are not written on A41.0, but they bind it: a note on a category applies to every code beneath it. Billing A41.0 with anything listed here is a denial.

Written on A41 — Other sepsis

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

Excludes2 inherited from the categories above A41.0

Also inherited, and the opposite of Excludes1: these conditions are not part of A41.0, but a patient can have both, so you may code both.

Other codes that can never be billed with A41.0

These codes carry an Excludes1 note pointing at A41.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading A41.0 alone.

Z16Resistance to antimicrobial drugs

Risk adjustment

A41.0 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.
