ICD-10 Code A41.89 – Other specified sepsis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A41.89 – Other specified sepsis
What it is
A41.89 identifies sepsis that is documented, but does not fit a more specific sepsis category. Use it when the provider names another specified form of sepsis and the record supports that diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Sepsis commonly presents with evidence of systemic infection and organ dysfunction, but you should code only what the provider explicitly documents.
When to use this code
Use A41.89 when the clinician documents sepsis with a specified type or cause that is not captured by another ICD-10 code. It may apply when the note clearly states a named sepsis diagnosis and no more specific code is available.
If the documentation is vague, incomplete, or conflicts with another sepsis category, check documentation before assigning this code. You should not infer the diagnosis from culture results or treatment alone.
Do not use for
Do not use A41.89 for sepsis with a specific organism or for septic shock, which may require different coding. Also avoid it when the record supports only infection without documented sepsis.
Coding tip
Code A41.89 only after confirming the provider’s exact sepsis wording and excluding more specific sepsis codes.
