What O70 covers · when clinicians use it
ICD-10 code O70 identifies Perineal laceration during delivery in the U.S. ICD-10-CM clinical and billing record set. It sits within the ICD-10-CM diagnosis classification, the section that groups related diagnoses so providers, payers, and public-health agencies report them consistently. Clinicians and medical coders apply O70 when an encounter's findings match the Perineal laceration during delivery description, attaching it to the patient record so downstream insurance claims, payer audits, quality reporting, and epidemiological surveillance all reference the same standardized diagnosis. The ICD-10-CM is maintained by the Centers for Medicare & Medicaid Services and the CDC's National Center for Health Statistics, with an updated official code set released each U.S. fiscal year — always verify O70 against the current CMS/CDC release and your payer's documentation guidance before final use. This page summarizes documentation context for O70 and is a coding reference, not clinical, diagnostic, or billing advice.
O70 refers to Perineal laceration during delivery, encompassing critical labor and delivery events such as preterm labor, labor arrest, obstructed labor, fetal distress, perineal injuries, postpartum hemorrhage, and anesthesia complications during childbirth.
Symptoms
- Early or strong contractions – Signaling preterm labor (O60)
- Prolonged or stalled labor – Indicative of failed induction or labor abnormalities (O61–O63)
- Severe maternal bleeding – Seen with intrapartum or postpartum hemorrhage (O67, O72)
- Fetal heart rate decelerations – Indicating fetal distress (O76, O77)
- Umbilical cord prolapse – A serious emergency under O69
Diagnosis
Diagnosis of Perineal laceration during delivery involves continuous intrapartum monitoring, cervical checks, fetal heart rate monitoring (CTG), assessment of uterine contractions, blood loss estimation, ultrasound imaging, and laboratory tests to monitor maternal and fetal status during labor and delivery.
ICD10 Code Usage
ICD10 code O70 is critical for obstetricians, labor and delivery nurses, and maternal-fetal medicine teams for accurately recording labor complications, planning emergency interventions, and ensuring optimal maternal and neonatal outcomes.

FAQs
Q1: What is ICD10 code O70?
A: It refers to Perineal laceration during delivery, which covers labor abnormalities, delivery trauma, postpartum complications, and fetal stress during the intrapartum period.
Q2: What causes failed induction of labor (O61)?
A: Causes include unfavorable cervix, ineffective uterine contractions, cephalopelvic disproportion, or fetal malposition.
Q3: What is postpartum hemorrhage (O72)?
A: Excessive bleeding after delivery, often due to uterine atony, retained placenta, or trauma.
Q4: How is fetal heart rate abnormality during labor (O76) managed?
A: Management may involve oxygen administration, maternal repositioning, fluid resuscitation, amnioinfusion, or emergency cesarean delivery.
Q5: How serious are umbilical cord complications (O69)?
A: They can lead to acute fetal distress, requiring immediate obstetric intervention to prevent stillbirth or hypoxic injury.
Conclusion
ICD10 code O70 enables comprehensive documentation and management of Perineal laceration during delivery, supporting safe delivery practices, timely interventions, and improved outcomes for both mother and child during labor and childbirth.
