Fetal anemia and thrombocytopenia, third trimester, fetus 2

This code signifies the presence of anemia and/or thrombocytopenia in the second 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 developing fetus.

Apply this code when documentation clearly indicates that the second fetus in a multiple gestation is diagnosed with either anemia or thrombocytopenia, or both, and the pregnancy is in the third trimester. Supporting documentation would include ultrasound reports, fetal blood sampling results, or physician notes specifying these conditions for the identified fetus.

• Ensure the documentation specifies "fetus 2" to differentiate from other fetuses in a multiple gestation.
• Verify the trimester of pregnancy is clearly documented as the third trimester.
• Do not use this code if only one of the conditions (anemia or thrombocytopenia) is present; there are more specific codes for those individual conditions.
