Septic pulmonary embolism without acute cor pulmonale

This code signifies a pulmonary embolism that originates from a septic source, such as an infected thrombus, but without the immediate development of acute right-sided heart failure. The embolus obstructs pulmonary arteries, leading to impaired blood flow to the lungs, and is directly linked to an underlying infection.

Use this code when documentation clearly indicates a pulmonary embolism caused by a bacterial or fungal infection, and there is no mention of acute cor pulmonale. This diagnosis is often supported by imaging studies confirming a pulmonary embolism and laboratory findings consistent with sepsis or a localized infection acting as the source.

• Always code the underlying septic condition or infection first, as it is the etiology of the pulmonary embolism.
• Distinguish carefully between septic and non-septic pulmonary emboli; documentation must specify the infectious origin.
• Do not use this code if acute cor pulmonale is documented; a more specific code for pulmonary embolism with acute cor pulmonale would be appropriate.
