Onset labor 37-39 weeks, w del by (planned) cesarean section

This code describes a delivery occurring via planned cesarean section when spontaneous labor began between 37 weeks 0 days and 38 weeks 6 days of gestation. It signifies a term pregnancy where labor initiated naturally, but the delivery method was a pre-scheduled surgical intervention.

Apply this code when documentation clearly indicates spontaneous onset of labor in a patient between 37+0 and 38+6 weeks gestation, followed by a planned cesarean section for delivery. This scenario often arises when a patient with a scheduled C-section goes into labor prematurely but still within the term window.

• Ensure documentation specifies "spontaneous" labor onset and "planned" cesarean section.
• Verify gestational age at the time of labor onset falls strictly between 37+0 and 38+6 weeks.
• This code is for the maternal record and should be sequenced as a secondary diagnosis following the primary outcome of delivery.
