O66.0
ICD-10-CMThis code represents a complication of labor where the fetal shoulders become lodged behind the maternal pubic symphysis after delivery of the head, preventing further descent. This obstetric emergency requires specific maneuvers to dislodge the shoulders and complete the delivery. It signifies a mechanical obstruction during the second stage of labor directly attributable to the fetal shoulder presentation.
Assign this code when documentation clearly indicates obstructed labor specifically due to shoulder dystocia. This typically occurs during vaginal delivery attempts and is often noted in the delivery summary or operative report. Supporting documentation will describe the need for specific maneuvers (e.g., McRoberts, suprapubic pressure) to resolve the dystocia.
