O70.2 Third degree perineal laceration during delivery

Name of the Condition

• Third degree perineal laceration during delivery

Summary

Third degree perineal laceration during delivery refers to a severe tear that occurs in the perineum during childbirth. This tear extends through the vaginal tissue, perineal muscles, and the anal sphincter but does not involve the rectal mucosa. It requires surgical repair to ensure proper healing.

Causes

Most commonly, third degree perineal lacerations occur due to the mechanical stress and stretching of the perineal tissues during vaginal delivery. The pressure exerted by the baby passing through the birth canal can cause significant tearing.

Risk Factors

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

Symptoms

• Significant pain and swelling in the perineal area
• Bleeding around the perineum
• Difficulty controlling bowel movements
• Discomfort during urination

Diagnosis

Diagnosis is made through a physical examination by a healthcare professional immediately after delivery. The provider assesses the extent of the tear by visually inspecting and manually examining the perineal area to determine the involvement of the anal sphincter.

Treatment Options

Treatment involves surgical repair to stitch the torn tissues, including the anal sphincter. Post-operative care includes pain relief management, stool softeners to prevent straining, and maintaining proper hygiene to avoid infection.

Prognosis and Follow-Up

With proper treatment, healing is typically successful. 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
• Prolonged pain or discomfort
• Difficulty with bowel control (incontinence)
• Delayed healing

Lifestyle & Prevention

• Prenatal perineal massage may help reduce the risk of severe tearing.
• Controlled pushing during delivery can minimize perineal stress.
• Avoiding unnecessary episiotomies may lower the likelihood of severe lacerations.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, excessive bleeding, signs of infection (e.g., fever, pus), or difficulty controlling bowel movements after delivery.

Tips for Medical Coders

When coding for third degree perineal laceration during delivery, ensure documentation clearly specifies the tear involves the anal sphincter but not the rectal mucosa. Verify that the delivery context is documented to support the use of this code.
