Fetal anemia and thrombocytopenia, third trimester, fetus 3

This code signifies the presence of anemia and/or thrombocytopenia in the third identified fetus of a multiple gestation pregnancy during the third trimester. These conditions indicate a deficiency in red blood cells (anemia) or platelets (thrombocytopenia) in the fetus, which can lead to various complications.

Use this code when documentation specifies fetal anemia and/or thrombocytopenia affecting the third fetus in a multifetal pregnancy, and the pregnancy is in the third trimester. Supporting documentation should include ultrasound findings, fetal blood sampling results, or other diagnostic reports confirming these conditions in the specified fetus.

• Ensure the documentation clearly identifies the affected fetus as "fetus 3" in a multiple gestation.
• Verify the gestational age falls within the third trimester (28 weeks to delivery).
• Do not use this code for anemia or thrombocytopenia in the mother; this code is exclusively for fetal conditions.
