Fetal anemia and thrombocytopenia, first trimester, fetus 5

This code signifies the diagnosis of anemia and/or thrombocytopenia in the fifth fetus of a multiple gestation pregnancy during the first trimester. These conditions indicate a deficiency in red blood cells or platelets, respectively, within the developing fetus, potentially impacting fetal health and development.

Apply this code when documentation explicitly states fetal anemia or thrombocytopenia affecting fetus 5 in a multifetal pregnancy, with the diagnosis occurring during the first trimester (up to the end of the 13th week of gestation). This diagnosis is typically made through advanced prenatal diagnostic techniques such as cordocentesis or detailed ultrasound.

• Ensure the documentation clearly specifies "fetus 5" to differentiate from other fetuses in a multiple gestation.
• Verify the trimester of diagnosis; this code is specific to the first trimester.
• Do not use this code for maternal anemia or thrombocytopenia; it is exclusively for fetal conditions.
