Fetal anemia and thrombocytopenia, unsp trimester, fetus 2

This code signifies the diagnosis of both anemia and thrombocytopenia in the second fetus of a multiple gestation pregnancy, where the specific trimester of diagnosis is not documented. These conditions indicate a deficiency in red blood cells and platelets, respectively, in the developing fetus.

This code is appropriate when documentation specifies both fetal anemia and thrombocytopenia affecting fetus 2 in a multifetal pregnancy, and the trimester of diagnosis is not recorded. It should be used when the physician's notes clearly identify these co-occurring hematologic issues in the specified fetus without a trimester.

• Ensure documentation explicitly identifies both anemia and thrombocytopenia in fetus 2.
• Avoid using this code if the trimester is known; instead, use the trimester-specific codes (O36.821- or O36.823-).
• This code is for the maternal record, indicating a complication affecting the fetus.
