Code Description

ICD-10 B66.8 is a billable code used to indicate a diagnosis of other specified cestodes.

Key Diagnostic Point:

Cestodes, commonly known as tapeworms, are a class of parasitic flatworms that can infect the intestines of humans and other animals. The ICD-10 code B66.8 is used to classify infections caused by cestodes that are not specifically identified in other codes. These infections can lead to a variety of gastrointestinal symptoms, including abdominal pain, diarrhea, and weight loss. Cestodes are typically transmitted through the ingestion of contaminated food or water, or through contact with infected animals. The most common types of cestodes affecting humans include Taenia saginata (beef tapeworm), Taenia solium (pork tapeworm), and Echinococcus species. Diagnosis often involves stool examination for eggs or proglottids, imaging studies, and serological tests. Treatment usually involves antiparasitic medications such as praziquantel or niclosamide, which are effective in eliminating the adult worms from the host. Proper coding for cestode infections is crucial for accurate epidemiological tracking and treatment reimbursement.

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of cestode species leading to different clinical presentations.
  • Need for precise documentation of symptoms and diagnostic tests.
  • Differentiation from other helminthic infections.
  • Potential for co-infections with other parasites.

Audit Risk Factors

  • Inadequate documentation of the specific cestode type.
  • Failure to document symptoms and diagnostic tests.
  • Misclassification of cestode infections as other helminthic infections.
  • Inconsistent treatment documentation.

Coding Guidelines

Inclusion Criteria

Use B66.8 When
  • According to ICD
  • 10 guidelines, B66
  • 8 should be used when the specific type of cestode is not documented
  • Coders should ensure that all relevant clinical information is captured to support the diagnosis

Exclusion Criteria

Do NOT use B66.8 When
  • Exclusion criteria include cases where the specific cestode is known and can be coded with a more specific code

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of parasitic infections, including cestodes. B66.8 provides a means to capture cases that do not fit neatly into other categories, improving data accuracy and treatment tracking.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of parasitic infections, including cestodes. B66.8 provides a means to capture cases that do not fit neatly into other categories, improving data accuracy and treatment tracking.

Reimbursement & Billing Impact

The transition to ICD-10 has allowed for more specific coding of parasitic infections, including cestodes. B66.8 provides a means to capture cases that do not fit neatly into other categories, improving data accuracy and treatment tracking.
