O70.20 Third degree perineal laceration during delivery, unspecified

Name of the Condition

• Third degree perineal laceration during delivery, unspecified

Summary

Third degree perineal laceration during delivery, unspecified (ICD code O70.20) refers to a severe tear in the perineum during childbirth that extends into the anal sphincter. This type of laceration involves the anal sphincter but does not specify whether it is complete or partial.

Causes

Most commonly, perineal lacerations occur as a result of the mechanical stress during vaginal delivery. The stretching and tearing of tissues as the baby passes through the birth canal are the primary causes.

Risk Factors

• First-time vaginal deliveries
• Large birth weight of the baby
• Use of forceps or vacuum assistance during delivery
• Episiotomies
• Prolonged second stage of labor

Symptoms

• Significant pain, swelling, and bleeding around the perineal area
• Difficulty controlling bowel movements
• Discomfort during urination
• Bruising or discoloration in the perineal region

Diagnosis

Diagnosis is primarily through a physical examination by a healthcare professional immediately after delivery to assess the extent of the tear. The provider evaluates the perineal area to determine the severity and involvement of the anal sphincter.

Treatment Options

• Surgical repair to stitch and mend the torn tissues
• Pain relief management with analgesics
• Use of stool softeners to prevent straining
• Maintaining proper hygiene to reduce infection risk
• Sitz baths to promote healing and provide relief

Prognosis and Follow-Up

With proper treatment, healing is typically successful, but regular follow-up is important to monitor recovery and address any complications such as infection or prolonged discomfort. Most patients recover fully with appropriate care.

Complications

• Infection at the site of the tear
• Delayed healing or wound breakdown
• Persistent pain or discomfort
• Long-term issues with bowel control (incontinence)
• Formation of fistulas (abnormal connections between tissues)

Lifestyle & Prevention

• Prenatal exercises to strengthen pelvic floor muscles
• Controlled pushing during delivery to reduce tissue stress
• Avoiding excessive forceps or vacuum use when possible
• Proper perineal massage in late pregnancy (under guidance)
• Maintaining good hygiene post-delivery to prevent infection

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, excessive bleeding, fever, or signs of infection (e.g., pus, worsening redness) after delivery. Contact your healthcare provider if you have difficulty with bowel movements or notice persistent incontinence.

Tips for Medical Coders

When coding O70.20, ensure documentation specifies the tear involves the anal sphincter but does not indicate whether it is complete or partial. Verify that the diagnosis is confirmed via physical examination and that the delivery context is clearly documented. Avoid using this code if the laceration is classified as first or second degree, or if it involves additional complications not specified here.
