Pyemic and septic embolism in pregnancy, third trimester

This code signifies the presence of a pyemic or septic embolism occurring during the third trimester of pregnancy. This condition involves the formation of an embolus (a blood clot, air bubble, or other foreign body) that travels through the bloodstream and lodges in a vessel, originating from a site of infection (sepsis) or pus formation (pyemia).

Apply this code when documentation clearly indicates a diagnosis of a septic or pyemic embolism in a pregnant patient who is specifically in her third trimester. Supporting documentation should detail the infectious origin of the embolus and the gestational period.

• Ensure the documentation explicitly states "third trimester" for accurate code assignment.
• Always code the underlying infection responsible for the pyemic or septic embolism first.
• Distinguish from non-septic embolisms; this code specifically requires an infectious etiology.
