Systemic inflammatory response syndrome (SIRS) of non-infectious origin
ICD-10 R65.1 is a billable code used to indicate a diagnosis of systemic inflammatory response syndrome (sirs) of non-infectious origin.
Systemic Inflammatory Response Syndrome (SIRS) of non-infectious origin is characterized by a systemic inflammatory response that can occur due to various non-infectious triggers. Symptoms may include fever, tachycardia, tachypnea, and leukocytosis or leukopenia. The syndrome can arise from conditions such as pancreatitis, trauma, burns, or autoimmune diseases. Clinically, SIRS is identified by the presence of at least two of the following criteria: body temperature >38°C or <36°C, heart rate >90 beats per minute, respiratory rate >20 breaths per minute or arterial CO2 tension <32 mmHg, and white blood cell count >12,000 cells/mm³ or <4,000 cells/mm³. Laboratory findings may reveal elevated inflammatory markers such as C-reactive protein (CRP) and procalcitonin. It is crucial to differentiate SIRS from sepsis, which is specifically caused by infection. Accurate diagnosis and coding are essential for appropriate management and reimbursement.
Detailed documentation of clinical findings, lab results, and the underlying non-infectious cause is essential.
Patients presenting with pancreatitis, autoimmune disorders, or severe trauma.
Ensure that the documentation clearly distinguishes SIRS from sepsis and includes all relevant clinical criteria.
Acute care documentation must include vital signs, lab results, and a clear assessment of the patient's condition.
Patients with acute trauma, burns, or severe allergic reactions presenting with SIRS symptoms.
Rapid assessment and documentation are critical; ensure that the non-infectious cause is identified and documented.
Used for patients presenting with SIRS symptoms in the emergency department.
Document the patient's presenting symptoms, vital signs, and any lab results.
Emergency medicine providers should ensure that the documentation supports the level of service billed.
The key clinical criteria for diagnosing SIRS include an abnormal body temperature, elevated heart rate, increased respiratory rate, and abnormal white blood cell count. At least two of these criteria must be met.
