ICD-10 Code A41.8 – Other specified sepsis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A41.8 – Other specified sepsis
What it is
A41.8 identifies sepsis caused by an organism or clinical circumstance not named in the more specific sepsis codes. Use it when the record clearly supports sepsis, but the documented cause does not fit another A41 category.
Clinical signs
Clinical features vary; refer to documentation. Sepsis is generally documented as a systemic response to infection with signs of organ dysfunction or severe illness, but you should code only what the provider states.
When to use this code
Use A41.8 when the provider documents sepsis and names a causative organism or source that is not captured by a more specific code. It may also fit when the record says “other specified sepsis” or gives a clear sepsis diagnosis without a better ICD-10 choice. Check documentation for organism, source, and any additional codes needed for the underlying infection.
Do not use for
Do not use this code for simple infection without sepsis, or when a more specific sepsis code applies. If the documentation is unclear, do not guess; check documentation.
Coding tip
Always code the documented sepsis first, then add the underlying infection or organism code when supported by the record.
