Other embolism in pregnancy, first trimester

This code signifies the occurrence of any type of embolism, other than those specifically classified elsewhere (e.g., amniotic fluid, pulmonary, cerebral venous sinus thrombosis), during the first trimester of a pregnancy. It indicates a blockage of a blood vessel by an embolus, which can lead to tissue ischemia or infarction, presenting a significant risk to both mother and fetus.

Apply this code when documentation clearly states an embolism of an unspecified or "other" type has occurred in a pregnant patient within the first 12 weeks of gestation. This includes conditions like peripheral arterial embolism or paradoxical embolism not otherwise specified. Supporting documentation should detail the presence of an embolism and the gestational age.

• Always confirm the specific type of embolism and the trimester of pregnancy from the medical record.
• Do not use this code if a more specific embolism code (e.g., O88.211 for embolism of pulmonary artery in pregnancy, first trimester) is available.
• Sequence this code as a primary diagnosis when the embolism is the main reason for the encounter, or as a secondary diagnosis when it is a co-morbidity affecting the pregnancy.
