2025 ICD-10-CM code O70.23

Third-degree perineal laceration during delivery, involving both the external and internal anal sphincters.

Adhere to official ICD-10-CM coding guidelines provided by the Centers for Medicare & Medicaid Services (CMS) and the World Health Organization (WHO).Ensure accurate documentation is available to support the coding choices.This code is for maternal records only and should not be included in the newborn's record.

Modifiers are not applicable to ICD-10 codes.Modifiers are used with CPT and HCPCS codes to add additional context to the procedure or service performed.

The medical necessity for coding O70.23 is established by the presence of a third-degree perineal laceration during childbirth.The severity of the tear warrants documentation and coding to reflect the extent of injury and the need for potential surgical repair and subsequent management.

The obstetrician or other qualified healthcare professional delivering the baby is responsible for diagnosing and treating the perineal laceration. This may involve surgical repair of the laceration.

IMPORTANT:Other codes within the O70 series might be applicable depending on the specific extent of the laceration (O70.20, O70.21, O70.22, O70.3, O70.4).Code O71.4 (Obstetric high vaginal laceration alone) should not be used concurrently if the perineum is also lacerated.

In simple words: This code describes a serious tear in the area between the vagina and anus that happened during childbirth.The tear is severe and affects the muscles that control bowel movements.

This code signifies a third-degree perineal laceration that occurred during childbirth.The laceration extends through the perineal muscles and involves a tear in both the external anal sphincter (EAS) and the internal anal sphincter (IAS). This is a severe perineal tear requiring more extensive repair.

Example 1: A 30-year-old primipara (first-time mother) experiences a third-degree perineal laceration during vaginal delivery. The laceration involves both the external and internal anal sphincters, requiring surgical repair. Code O70.23 is applied., A 25-year-old multipara experiences a third-degree perineal laceration during a precipitous (rapid) vaginal delivery. The laceration is extensive, requiring immediate surgical repair to prevent complications.Code O70.23 is applied along with codes reflecting the repair procedure., A 35-year-old patient with a history of prior perineal trauma undergoes a vaginal delivery. During delivery, a third-degree perineal laceration occurs, requiring surgical repair in the operating room. Code O70.23 is used to document the laceration, alongside codes that specify the surgical repair.

Detailed documentation should include the degree of the laceration (IIIc), extent of involvement of the anal sphincters, the method of delivery, and details of the repair (if performed).Operator notes and the patient's chart should clearly reflect the diagnosis.
