B68.0 Taenia solium taeniasis

Name of the Condition

• Taenia solium taeniasis

Summary

Taenia solium taeniasis is a parasitic infection caused by the tapeworm Taenia solium. The condition arises from consuming undercooked or raw pork contaminated with tapeworm larvae. It may be asymptomatic or cause mild gastrointestinal symptoms, depending on the infection burden. The infection is generally treatable with appropriate antiparasitic therapy.

Causes

Taenia solium taeniasis is caused by ingesting the larvae of Taenia solium, which are present in undercooked or raw pork from infected pigs. Once ingested, the larvae develop into adult tapeworms in the human intestine, where they attach to the intestinal wall and grow.

Risk Factors

• Consumption of raw or undercooked pork.
• Poor food hygiene practices, such as inadequate cooking or cross-contamination.
• Travel to regions with high rates of Taenia solium infection.
• Lack of access to safe food preparation methods.

Symptoms

• Mild abdominal discomfort or pain.
• Nausea or vomiting.
• Loss of appetite or weight loss.
• Visible segments of the tapeworm in stool (rare).

Diagnosis

Diagnosis is typically confirmed by identifying tapeworm eggs or segments in stool samples. Microscopic examination of stool or imaging studies may be used to detect the presence of the parasite.

Treatment Options

Treatment usually involves antiparasitic medications, such as praziquantel or niclosamide, to eliminate the tapeworm. Follow-up stool examinations may be recommended to ensure the infection has been cleared.

Prognosis and Follow-Up

With appropriate treatment, the prognosis is generally good, and most individuals recover fully. Follow-up may be necessary to confirm eradication of the parasite and monitor for recurrence.

Complications

In rare cases, complications can include intestinal obstruction or cysticercosis (larval infection in other tissues) if eggs are ingested.

Lifestyle & Prevention

• Cook pork thoroughly to kill tapeworm larvae.
• Practice good food hygiene to avoid cross-contamination.
• Avoid consuming raw or undercooked pork, especially in regions with high infection rates.

When to Seek Professional Help

Seek medical attention if you experience persistent gastrointestinal symptoms, notice tapeworm segments in stool, or have traveled to areas with high Taenia solium prevalence.

Tips for Medical Coders

When coding for Taenia solium taeniasis (ICD10CM code B68.0), ensure documentation supports the specific diagnosis. Include details about exposure to undercooked pork or travel history if available, as these may support the clinical context. Verify that the code aligns with the confirmed diagnosis and any associated complications.
