Systemic Inflammatory Response Syndrome without Underlying Cause
A patient with fever and leukocytosis is admitted to the hospital for workup to rule out infection. No clear source of the symptoms was found, and the patient was diagnosed with SIRS as the discharge diagnosis. What is the appropriate principal diagnosis when a patient presents with SIRS and no underlying cause is found, SIRS (R65.10) or the symptoms, e.g., fever, leukocytosis, etc.? There is a “code first” note at category R65.1, Systemic inflammatory response syndrome (SIRS) of non-infectious origin, which states to “code first underlying condition.” ...

Article Overview
This premium article explains a coding scenario involving systemic inflammatory response syndrome in an inpatient admission where an underlying cause is not found. It is intended for coders, CDI staff, and billers who need to understand how this topic is discussed in relation to symptom-based documentation, category-level instructional notes, and principal diagnosis selection. The guidance is presented as a short Q&A-style discussion focused on when the diagnosis is reported and how related documentation is interpreted at a high level.
Why This Topic Matters
Correctly understanding how SIRS is handled when no cause is identified can affect diagnosis reporting, sequencing, and the accuracy of coded claims. The article helps coding professionals recognize the documentation issue and the kind of official note-based guidance involved.
