What This Code Means
A41 is the ICD-10-CM diagnosis code for other sepsis. A41 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering other bacterial diseases (a30-a49).
Header codes like A41 cannot be reported on claims directly; they organize child codes that share clinical context. Coders should select the billable child code that matches the documented presentation and then verify its current source-backed HCC mapping. Do not infer a child code or risk adjustment value from the header alone.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for A41 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
