Code Description

ICD-10 B67.61 is a billable code used to indicate a diagnosis of echinococcus multilocularis infection, multiple sites.

Key Diagnostic Point:

Echinococcus multilocularis infection is a parasitic disease caused by the larval stage of the Echinococcus multilocularis tapeworm, primarily affecting the liver but can also involve other organs. This infection is endemic in certain regions, particularly in the Northern Hemisphere, where it is transmitted through contact with infected canids, such as foxes and domestic dogs, or through ingestion of contaminated food or water. The disease can lead to the formation of multilocular cysts that mimic malignancy, causing significant morbidity. Symptoms may include abdominal pain, jaundice, and weight loss, and the condition can progress to liver failure if left untreated. Diagnosis is typically made through imaging studies, serological tests, and sometimes histopathological examination. Treatment often involves surgical intervention to remove cysts, along with antiparasitic medications such as albendazole or mebendazole to manage the infection and prevent recurrence.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires knowledge of parasitic infections and their transmission.
  • Differentiation from other liver lesions or malignancies.
  • Need for accurate documentation of multiple sites of infection.
  • Potential for co-infections or complications that must be coded appropriately.

Audit Risk Factors

  • Inadequate documentation of symptoms and clinical findings.
  • Failure to specify multiple sites of infection.
  • Misclassification of the infection as a different parasitic disease.
  • Lack of supporting imaging or laboratory results.

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of parasitic infections, improving the accuracy of data collection and reimbursement processes. B67.61 provides a clear distinction for Echinococcus multilocularis infections, which aids in epidemiological tracking and treatment planning.

ICD-9 vs ICD-10
