Fetal anemia and thrombocytopenia, first trimester, unsp

This code signifies the presence of fetal anemia and/or thrombocytopenia identified during the first trimester of pregnancy. It indicates a hematological abnormality in the fetus, specifically a low red blood cell count (anemia) and/or a low platelet count (thrombocytopenia), detected early in gestation.

Use this code when documentation confirms fetal anemia and/or thrombocytopenia diagnosed in the first trimester, and further specificity regarding the trimester or applicability is not provided or is not relevant. This would typically be supported by ultrasound findings, fetal blood sampling (if performed), or other diagnostic tests indicating these conditions.

• Ensure documentation clearly specifies the first trimester for both conditions.
• If the specific type or cause of fetal anemia/thrombocytopenia is known, consider more specific codes if available.
• Always sequence this code after the primary obstetric complication if applicable, or as the primary diagnosis if the fetal condition is the focus of the encounter.
