I84.113 Internal strangulated hemorrhoids

Name of the Condition

• Internal Strangulated Hemorrhoids
• ICD-10 Code: I84.113

Summary

Internal strangulated hemorrhoids occur when internal hemorrhoidal tissue becomes trapped and its blood supply is cut off, leading to tissue ischemia or necrosis. This condition involves the internal hemorrhoidal veins within the rectum or anal canal, where the prolapsed tissue cannot return to its normal position, resulting in compromised blood flow. Strangulation is a serious complication that requires prompt medical attention to prevent tissue damage.

Causes

Strangulation of internal hemorrhoids typically results from increased pressure in the rectal veins, causing the swollen tissue to prolapse and become trapped outside the anal canal. Common triggers include straining during bowel movements, chronic constipation or diarrhea, prolonged sitting, and pregnancy. The trapped tissue compresses blood vessels, disrupting circulation and leading to ischemia.

Risk Factors

• Chronic constipation or diarrhea
• Straining during bowel movements
• Prolonged sitting or standing
• Obesity
• Pregnancy
• Aging
• Heavy lifting
• Family history of hemorrhoids

Symptoms

• Severe pain or throbbing in the anal area
• Swollen, tender lump protruding from the anus
• Inability to reduce the prolapsed tissue
• Dark or discolored tissue (indicating ischemia)
• Fever or chills (if infection develops)
• Bleeding or discharge from the affected area

Diagnosis

Diagnosis is based on clinical evaluation, including a physical examination to assess the prolapsed tissue and check for signs of strangulation, such as discoloration or tenderness. A digital rectal exam or anoscopy may be performed to visualize the internal hemorrhoids and confirm the absence of blood flow. Imaging or further tests are rarely needed unless complications like infection are suspected.

Treatment Options

Treatment focuses on relieving the strangulation and restoring blood flow. Initial management may include manual reduction of the prolapsed tissue, warm sitz baths, and pain relief. Severe cases may require surgical intervention, such as hemorrhoidectomy or rubber band ligation, to remove or fix the affected tissue. Antibiotics may be prescribed if infection is present.

Prognosis and Follow-Up

With prompt treatment, the prognosis is generally good, and most patients recover without long-term complications. Follow-up care involves monitoring for recurrence and addressing underlying risk factors, such as constipation or straining. Regular check-ups may be recommended to prevent future episodes.

Complications

• Tissue necrosis (death of the strangulated tissue)
• Infection or abscess formation
• Chronic pain or discomfort
• Recurrent prolapse
• Rarely, sepsis or other systemic complications

Lifestyle & Prevention

• Maintain regular bowel habits and avoid straining.
• Increase fiber intake and stay hydrated to prevent constipation.
• Avoid prolonged sitting or standing.
• Exercise regularly to improve circulation.
• Manage weight and avoid heavy lifting when possible.

When to Seek Professional Help

Seek immediate medical attention if you experience severe anal pain, a lump that cannot be reduced, fever, or signs of infection. These symptoms may indicate strangulation or other serious complications requiring urgent care.

Tips for Medical Coders

Document the presence of strangulation and its impact on blood flow clearly. Note whether the hemorrhoids are internal and if the tissue is prolapsed or trapped. Ensure the clinical record supports the diagnosis by describing symptoms like pain, discoloration, or inability to reduce the tissue. Use I84.113 only when the documentation confirms internal strangulated hemorrhoids.
