Fetal anemia and thrombocytopenia, unsp trimester, fetus 4

This code indicates the presence of fetal anemia and thrombocytopenia in a pregnancy where the specific trimester of diagnosis is not documented. It applies to the fourth fetus in a multiple gestation pregnancy. This condition involves a reduction in red blood cells and platelets in the developing fetus.

Use this code when documentation confirms both fetal anemia and thrombocytopenia, and the specific trimester of diagnosis is not specified. This code is appropriate for cases involving the fourth fetus in a multifetal pregnancy. Documentation should clearly identify the affected fetus as the fourth in a multiple gestation.

• Ensure documentation specifies "fetus 4" to differentiate from other fetuses in a multiple gestation.
• Avoid using this code if a specific trimester (first, second, or third) is documented; instead, use the appropriate trimester-specific code.
• Confirm both anemia and thrombocytopenia are present; if only one is documented, a more specific code should be used.
