Septicemia and Sepsis
Septicemia and Sepsis are no longer synonymous terms
AHA Coding Clinic for ICD-9-CM, Fourth Quarter, 2003
![Page 6: Sepsis New Guidelines, New Codes](https://reader036.vdocuments.us/reader036/viewer/2022062319/55505079b4c9058f768b5475/html5/thumbnails/6.jpg)
Coding “Sepsis”
Sepsis requires two codes
Underlying condition 038.x
and
995.91 or 995.92
Per Instructional notes in Tabular Index.
![Page 7: Sepsis New Guidelines, New Codes](https://reader036.vdocuments.us/reader036/viewer/2022062319/55505079b4c9058f768b5475/html5/thumbnails/7.jpg)
995.9x SIRS
Systemic Inflammatory Response Syndrome
A major complication of infection and/or trauma that includes systemic inflammation, elevated or reduced temperature, rapid heart rate and respiration, and elevated white blood cell count that may progress into organ and multi-organ failure.
![Page 8: Sepsis New Guidelines, New Codes](https://reader036.vdocuments.us/reader036/viewer/2022062319/55505079b4c9058f768b5475/html5/thumbnails/8.jpg)
995.9x SIRS
Two or more of the following: Temperature >38 C or <36 C Heart Rate > 90 beats per minute Respiratory Rate > 20 breaths per minute or
PaCO2 < 32 mm Hg White Blood Cell Count > 12,000/cu mm,
<4,000/cu mm or >10% immature (band) forms

995.9x SIRS
995.90 SIRS, unspecified
995.91 … due to infectious process. Sepsis 995.92 … due to infectious process w/ organ
dysfunction. Severe Sepsis
995.93 … due to non-infectious process 995.94 … due to non-infectious process w/
organ dysfunction
![Page 11: Sepsis New Guidelines, New Codes](https://reader036.vdocuments.us/reader036/viewer/2022062319/55505079b4c9058f768b5475/html5/thumbnails/11.jpg)
995.9x SIRS sequencing
Code first the underlying cause
Use an infection or trauma code plus 995.9x (SIRS) to accurately reflect severity
In absence of underlying condition, 995.90 SIRS is used as the principal diagnosis
![Page 12: Sepsis New Guidelines, New Codes](https://reader036.vdocuments.us/reader036/viewer/2022062319/55505079b4c9058f768b5475/html5/thumbnails/12.jpg)
995.92 and 995.94
In presence of organ dysfunction use additional code to specify the organ dysfunction, e.g.: Acute renal failure (584.5-584.9 ) Acute respiratory failure (518.81) Critical illness myopathy (359.81) Critical illness polyneuropathy (357.82) Encephalopathy (348.31) Hepatic failure (570) Kidney failure (584.5-584.9, 585, 586) Septic shock (785.52)

OR 038.9, 995.92, 518.81, 507.0?
Until we get Coding Clinic guidance: Cause is important – what caused the respiratory
failure? Severe sepsis, or pneumonia? Respiratory Failure is included in severe sepsis
(though coded separately)
![Page 28: Sepsis New Guidelines, New Codes](https://reader036.vdocuments.us/reader036/viewer/2022062319/55505079b4c9058f768b5475/html5/thumbnails/28.jpg)

Line Sepsis 996.62, 038.9, 995.91
OR 038.9, 995.91, 996.62 ?
Based on previous guidance, the complication code is sequenced first. Similar to the “poisoning” chapter, the case is classified and coded to the Complications chapter.

What can you do?
Why does it getting it right matter? Severity of illness Statistics Reimbursement
What can you do? Work to improve documentation Talk to infectious disease staff Talk to trauma staff Talk to ICU intensivists
