Septic arterial embolism

This code represents an arterial occlusion caused by an infected thrombus or other embolic material originating from a septic source. This condition can lead to ischemia and infarction in the affected arterial distribution, potentially impacting various organs or limbs. The embolism is distinct from a sterile arterial embolism due to its infectious etiology.

Use this code when documentation clearly indicates an arterial embolism with a confirmed or suspected septic origin. This typically occurs in patients with underlying infections such as endocarditis, abscesses, or infected intravenous catheters, where bacterial vegetations or infected clots dislodge and travel through the arterial system. Documentation should specify both the arterial occlusion and the septic nature of the embolus.

• Differentiate from sterile arterial embolisms; the "septic" aspect is crucial for this code.
• Do not use for septic pulmonary embolisms, as these are classified separately under I26.
• Always code the underlying infection responsible for the septic embolism, if known, as a primary or secondary diagnosis.
