O70.22 Third degree perineal laceration during delivery, IIIb

Name of the Condition

• Third degree perineal laceration during delivery, IIIb

Summary

Third degree perineal laceration during delivery, IIIb 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, involving 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 and rectal mucosa.

Treatment Options

Treatment involves surgical repair to stitch the torn tissues, including the anal sphincter and rectal mucosa. Post-operative care includes pain relief management, use of stool softeners, and maintaining proper hygiene.

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. Follow-up appointments may involve assessing bowel and urinary function.

Complications

• Infection at the site of the tear
• Prolonged pain or discomfort
• Difficulty with bowel or urinary control
• Fistula formation (abnormal connection between the rectum and vagina)

Lifestyle & Prevention

• Pelvic floor exercises during pregnancy may help strengthen muscles
• Controlled pushing during delivery can reduce tearing risk
• Avoiding excessive forceps or vacuum use when possible
• Discussing delivery plans with healthcare providers to minimize risk factors

When to Seek Professional Help

Seek immediate medical attention if experiencing severe pain, excessive bleeding, fever, or signs of infection (e.g., pus, worsening swelling) after delivery. Also, consult a provider if bowel or urinary control issues persist.

Tips for Medical Coders

Document the extent of the tear, including involvement of the anal sphincter and rectal mucosa, to support accurate coding. Ensure clinical notes specify the anatomical structures affected and any surgical interventions performed.
