Fetal anemia and thrombocytopenia, second trimester, fetus 1

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

Apply this code when documentation confirms fetal anemia and/or thrombocytopenia identified in the second trimester for a singleton pregnancy. This typically follows diagnostic procedures such as fetal blood sampling (cordocentesis) or Doppler ultrasound findings suggestive of these conditions.

• Ensure documentation specifies "fetus 1" for singleton pregnancies; for multiple gestations, use the appropriate code for the affected fetus.
• Confirm the trimester of diagnosis is explicitly stated as the second trimester.
• Do not confuse with codes for maternal anemia or thrombocytopenia; this code specifically refers to the fetal condition.
