Fetal anemia and thrombocytopenia, unsp trimester, fetus 5

This code signifies the presence of anemia and thrombocytopenia in the fifth fetus of a multiple gestation pregnancy, where the specific trimester of gestation is not documented. It indicates a hematologic abnormality affecting fetal health, requiring clinical attention and monitoring.

Use this code when documentation clearly identifies both fetal anemia and thrombocytopenia in the fifth fetus of a multiple pregnancy, and the trimester of gestation is not specified. This code is appropriate when the medical record explicitly states "fetus 5" in the context of these conditions.

• Ensure documentation specifies "fetus 5" to differentiate from other fetuses in a multiple gestation.
• Avoid using this code if the trimester is known; instead, select the appropriate trimester-specific code (e.g., O36.8215, O36.8225, O36.8235).
• Always sequence this code as a secondary diagnosis following the primary obstetric code indicating the reason for the encounter.
