Labor and delivery complicated by vasa previa, unsp

This code describes a pregnancy where the fetal blood vessels (vasa previa) lie exposed within the membranes over the cervical os, unprotected by Wharton's jelly or placental tissue. This condition places the fetus at high risk for exsanguination if the membranes rupture, as the vessels can tear. It specifically indicates that the complication occurred during labor and delivery.

Use this code when documentation confirms vasa previa was identified and complicated the labor and delivery process. This diagnosis is typically made antenatally via ultrasound with color Doppler, but may be discovered intrapartum. Documentation should clearly state the presence of vasa previa and its impact on the delivery.

• Ensure documentation specifies "labor and delivery complicated by" vasa previa, not just "vasa previa" identified antenatally.
• This code is for the maternal record; a separate code for the newborn's condition (e.g., P02.7) may also be necessary if affected.
• Do not confuse with placenta previa (O44.-) or vasa previa identified but not complicating labor and delivery (O43.12-).
