Fetal anemia and thrombocytopenia, second trimester, fetus 2

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

Apply this code when documentation clearly identifies fetal anemia or thrombocytopenia specifically impacting fetus 2 in a multifetal pregnancy during the second trimester. This diagnosis is typically made through prenatal testing such as ultrasound, Doppler studies, or fetal blood sampling.

• Ensure the documentation specifies "fetus 2" and "second trimester" for accurate code assignment.
• Do not confuse this with codes for other fetal conditions or conditions affecting the mother.
• Always sequence this code after the primary obstetric code indicating the multiple gestation.
