Triplet preg w two or more monochorionic fetuses, unsp tri

This code identifies a triplet gestation where at least two of the fetuses share a single chorion, indicating they are monozygotic and share a placenta. The specific trimester of the pregnancy is not documented or is unknown. This condition carries increased risks due to potential complications associated with shared placental circulation.

Apply this code when documentation confirms a triplet pregnancy with two or more monochorionic fetuses, but the trimester is not specified or is not yet determined. This diagnosis is typically established via ultrasound findings demonstrating shared chorionicity among multiple fetuses.

• Ensure documentation clearly states "triplet pregnancy" and "monochorionic" for at least two fetuses.
• Avoid using this code if the specific trimester (e.g., first, second, third) is documented; instead, select the more specific code.
• This code is for the maternal condition; additional codes for fetal conditions or complications should be reported separately.
