ICD-10 Code A41.52 – Sepsis due to Pseudomonas (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A41.52 – Sepsis due to Pseudomonas
What it is
This code identifies sepsis caused by a Pseudomonas infection. Use it when the record shows a systemic inflammatory response or sepsis attributed to Pseudomonas species.
Clinical signs
Clinical features vary; refer to documentation. Typical sepsis findings may include infection with organ dysfunction, altered mental status, fever or hypothermia, and hemodynamic instability.
When to use this code
Use A41.52 when the provider documents sepsis due to Pseudomonas, such as bloodstream infection or another confirmed source with sepsis. You should also code the underlying infection site when documented. If the organism or sepsis relationship is unclear, check documentation.
Do not use for
Do not use this code for Pseudomonas infection without sepsis, or for suspected infection without provider confirmation. Do not assign it when another organism is documented as the cause.
Coding tip
Confirm both the sepsis diagnosis and the Pseudomonas attribution in the provider note before assigning A41.52.
