Labor and delivery complicated by vasa previa, fetus 2

This code signifies a pregnancy where the fetal blood vessels (vasa previa) are positioned over or near the internal cervical os, unprotected by the umbilical cord or placental tissue, leading to a high risk of rupture during labor and delivery. This condition specifically complicates the delivery of the second fetus in a multiple gestation pregnancy.

Apply this code when documentation clearly indicates vasa previa as a complication during the labor and delivery encounter for the second twin or multiple. Supporting documentation should include ultrasound findings confirming vasa previa and notes detailing its impact on the delivery process of the specific fetus.

• Ensure the documentation specifies "fetus 2" to accurately assign this specific code.
• Do not use this code if vasa previa is noted but does not complicate the actual labor and delivery.
• Sequence this code as a secondary diagnosis following the primary code for the outcome of delivery (e.g., Z37.2 for twins, liveborn).
