Fetal anemia and thrombocytopenia, second trimester, oth

This diagnosis code indicates the presence of both anemia and thrombocytopenia in a fetus during the second trimester of pregnancy. It specifically applies when these conditions affect a fetus other than the first-listed or primary fetus in a multiple gestation.

Use this code when documentation clearly identifies a second-trimester fetus (in a multiple gestation) experiencing both a low red blood cell count (anemia) and a low platelet count (thrombocytopenia). This diagnosis is typically supported by fetal ultrasound findings, fetal blood sampling (cordocentesis), or other diagnostic tests confirming both conditions in a specific fetus.

• Ensure documentation specifies "other fetus" in a multiple gestation to differentiate from the primary fetus.
• Confirm both anemia and thrombocytopenia are present; do not use if only one condition is documented.
• Verify the gestational age falls within the second trimester (14 weeks 0 days to 27 weeks 6 days).
