Amniotic fluid embolism in the puerperium

This code signifies a rare but severe obstetric emergency where amniotic fluid, fetal cells, hair, or other debris enters the maternal bloodstream, triggering an anaphylactoid reaction during the postpartum period. It leads to acute respiratory distress, cardiovascular collapse, and coagulopathy, often with a high mortality rate. This condition represents a critical complication occurring after childbirth.

Assign this code when documentation explicitly states amniotic fluid embolism occurring during the puerperium, which is the period immediately following childbirth up to six weeks postpartum. Supporting documentation should detail the sudden onset of dyspnea, hypotension, and hemorrhage in a recently delivered patient, consistent with an anaphylactoid syndrome. This code is appropriate when the embolism is confirmed or strongly suspected clinically in the postpartum period.

• Ensure the documentation clearly specifies the timing of the embolism as occurring during the puerperium, not during labor or delivery.
• Always sequence this code as a principal diagnosis when it is the primary reason for admission or encounter.
• Look for associated codes for complications such as disseminated intravascular coagulation (DIC) or acute respiratory failure, and code them accordingly.
