T18.3 Foreign body in small intestine

Name of the Condition

• Foreign body in small intestine
  
  • ICD-10-CM Code: T18.3

Summary

A foreign body in the small intestine refers to an object that has been ingested and lodged within the small intestine. This can occur in both children and adults and may lead to complications such as obstruction or perforation if not addressed.

Causes

Ingestion of non-food items, such as coins, toys, or other small objects, is a common cause. Accidental ingestion of larger food particles or items not meant for consumption can also result in a foreign body in the small intestine.

Risk Factors

• Children: Natural curiosity and tendency to put objects in their mouth.
• Adults with mental health disorders, cognitive impairment, or intoxication.
• Wearing dental appliances, such as partial dentures, which can trigger accidental ingestion.
• History of pica or other eating disorders involving non-food items.

Symptoms

• Abdominal pain or discomfort.
• Nausea and vomiting.
• Difficulty swallowing.
• Gastrointestinal blockage signs, like inability to pass gas or stool.
• Bloating or distension.
• Rectal bleeding (if perforation occurs).

Diagnosis

Diagnosis typically involves imaging tests such as X-ray, CT scan, or MRI to identify the object's location and nature. Endoscopy may be used for both diagnostic and treatment purposes, especially if the object is accessible.

Treatment Options

• Observation: In some cases, the object may pass naturally through the intestines.
• Endoscopic Removal: Non-surgically retrieving the object using specialized tools.
• Surgery: In cases of obstruction, perforation, or unsuccessful endoscopic retrieval.

Prognosis and Follow-Up

Prognosis depends on the size, type, and location of the foreign body, as well as the presence of complications. Most cases resolve with appropriate treatment, but follow-up imaging or endoscopy may be needed to ensure complete removal and assess for damage.

Complications

• Intestinal obstruction or perforation.
• Infection or abscess formation.
• Bleeding or fistula development.
• Peritonitis in severe cases.

Lifestyle & Prevention

• Supervise young children to prevent accidental ingestion.
• Avoid eating or drinking while distracted or intoxicated.
• Keep small objects out of reach of children.
• Address underlying conditions like pica or swallowing disorders.

When to Seek Professional Help

Seek immediate medical attention if experiencing severe abdominal pain, vomiting, inability to pass stool or gas, or signs of infection (e.g., fever, chills).

Tips for Medical Coders

Document the type of foreign body (if known), location, and any associated complications. Ensure the encounter type (e.g., initial, subsequent) is clearly specified. Include details about diagnostic methods and treatment provided to support code assignment.
