Code Description

ICD-10 B56 is a billable code used to indicate a diagnosis of amebiasis.

Key Diagnostic Point:

Amebiasis is an intestinal infection caused by the protozoan parasite Entamoeba histolytica. It primarily affects the gastrointestinal tract, leading to symptoms such as diarrhea, abdominal pain, and dysentery. The infection is prevalent in tropical and subtropical regions, particularly in areas with poor sanitation and hygiene practices. Transmission occurs through the fecal-oral route, often via contaminated food or water. In severe cases, amebiasis can lead to complications such as colonic perforation or liver abscesses. Diagnosis is typically made through stool examination, serological tests, or imaging studies in cases of extraintestinal involvement. Treatment usually involves the use of anti-amoebic medications such as metronidazole or tinidazole, followed by a luminal agent like iodoquinol or paromomycin to eliminate cysts from the intestinal lumen. Public health measures focusing on sanitation and hygiene are crucial in preventing the spread of this disease.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between intestinal and extraintestinal amebiasis.
  • Understanding the various treatment protocols and their documentation.
  • Identifying co-existing conditions that may complicate coding.
  • Navigating the nuances of tropical disease coding.

Audit Risk Factors

  • Inadequate documentation of symptoms and treatment.
  • Failure to specify the type of amebiasis (intestinal vs. extraintestinal).
  • Misclassification of the condition due to overlapping symptoms with other gastrointestinal diseases.
  • Lack of follow-up documentation for treatment efficacy.
