Fetal anemia and thrombocytopenia, third trimester, fetus 4

This code signifies the presence of both anemia and thrombocytopenia in the fourth fetus of a multiple gestation pregnancy during the third trimester. These conditions indicate a deficiency in red blood cells and platelets, respectively, affecting the developing fetus.

Apply this code when documentation explicitly states both fetal anemia and fetal thrombocytopenia are diagnosed in the fourth fetus during the third trimester of a multifetal pregnancy. This typically arises from antenatal diagnostic testing, such as umbilical cord blood sampling or Doppler studies, confirming these hematologic abnormalities.

• Ensure documentation clearly specifies both anemia and thrombocytopenia; if only one is present, a different code is required.
• Verify the gestational trimester (third) and the specific fetus number (fourth) are explicitly documented.
• This code is for the fetal condition; maternal conditions causing fetal anemia/thrombocytopenia should be coded separately.
