Air embolism in pregnancy, unspecified trimester

This code signifies the presence of an air embolism occurring during any stage of pregnancy. An air embolism is a blockage of blood supply caused by one or more bubbles of air or other gas in the bloodstream, which can be a life-threatening complication for both the mother and the fetus.

Use this code when documentation confirms an air embolism in a pregnant patient, and the specific trimester is not documented or is unknown. This diagnosis is often associated with invasive procedures during pregnancy, such as amniocentesis, or complications during labor and delivery.

• Always attempt to clarify the specific trimester if possible, as more specific codes exist (O88.011, O88.012, O88.013).
• Code any associated complications of the air embolism, such as cardiac arrest or stroke, in addition to this code.
• Ensure documentation clearly states "air embolism" and its occurrence during pregnancy.
