    ICD-10-CM Code For Long Labor: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group O63 includes prolonged and arrested labor diagnoses such as prolonged first stage of labor, prolonged second stage of labor, and other labor dystocia conditions that cover delays in normal progress of labor and related complications. These ICD-10-CM diagnosis codes are used to document clinical scenarios involving slow or halted progression of labor, capturing factors like stage of labor, duration, and need for interventions. Accurate coding within the ICD-10-CM O63 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM O63: Long Labor Overview

    The diagnoses in this group represent prolonged or arrested labor events occurring during the first or second stage of labor, often related to fetal position, inadequate uterine contraction, or pelvic outlet problems. They target the obstetric process of labor and delivery and complications that can affect maternal and fetal outcomes. Accurate coding matters for complete clinical documentation and supports appropriate reimbursement for care related to complicated labor management.

    Typical Clinical Scenarios

    • A 28-year-old primigravida at 42 weeks gestation presents to labor and delivery after prolonged contractions for more than 20 hours with minimal cervical change and maternal exhaustion. Fetal monitoring is reassuring but labor has failed to progress despite adequate contractions and oxytocin augmentation; the team documents prolonged first stage labor requiring consideration of operative delivery. A code from this group is assigned to capture prolonged labor as the primary complication of the labor course. Typical codes: O63.0, O63.9
    • A 35-year-old multiparous woman in active labor develops arrest of descent in the second stage after pushing for several hours with fetal head at +2 and evidence of maternal fatigue and fetal borderline tracing. She presents urgently for evaluation and ultimately requires assisted vaginal delivery with vacuum due to failure to progress in the second stage. The diagnosis is assigned to reflect prolonged second stage labor as a complication leading to operative intervention. Typical codes: O63.1, O63.9
    • A 30-year-old woman with induction of labor for preeclampsia undergoing oxytocin infusion experiences prolonged latent phase with inadequate cervical dilation over an extended induction period and repeated augmentation attempts. She is admitted for extended monitoring and eventual cesarean delivery for failed induction/prolonged labor, and a code from this group is used to document the prolonged/failed labor course complicating delivery. Typical codes: O63.2, O63.9
