Newborn affected by hemorrhage into maternal circulation

This code identifies a newborn diagnosed with anemia or other complications resulting from blood loss into the mother's bloodstream during pregnancy or delivery. This condition occurs when fetal red blood cells cross the placental barrier and enter the maternal circulation, leading to fetal blood depletion.

Apply this code when documentation confirms a diagnosis of fetal-maternal hemorrhage affecting the newborn, often evidenced by neonatal anemia, hydrops fetalis, or other signs of fetal blood loss. Supporting documentation typically includes Kleihauer-Betke test results, fetal hemoglobin levels, and clinical signs of neonatal anemia.

• Ensure the documentation clearly states the hemorrhage originated from the fetus into the maternal circulation, not vice versa.
• Do not confuse with codes for maternal hemorrhage affecting the newborn (e.g., P50.0-P50.3).
• Sequence this code as a secondary diagnosis if the primary reason for admission is a more specific complication directly resulting from the hemorrhage.
