Fetal anemia and thrombocytopenia, first trimester, fetus 3

This diagnosis code signifies the presence of fetal anemia and thrombocytopenia in the third fetus of a multiple gestation pregnancy, occurring during the first trimester. This condition indicates a deficiency in red blood cells and platelets in the developing fetus, potentially leading to significant health complications.

Apply this code when documentation clearly indicates both fetal anemia and thrombocytopenia are diagnosed in the third fetus of a multifetal pregnancy during the first trimester. Supporting documentation would include ultrasound reports, fetal blood sampling results, and physician notes confirming the specific fetus affected and the gestational age at diagnosis.

• Ensure the documentation specifies "fetus 3" to differentiate from other fetuses in a multiple gestation.
• Verify the trimester of diagnosis is explicitly stated as the first trimester.
• Do not use this code if only anemia or only thrombocytopenia is present; both conditions must be documented.
