Code Description

ICD-10 A20.8 is a billable code used to indicate a diagnosis of enteric yersiniosis.

Key Diagnostic Point:

Enteric yersiniosis is an infectious disease caused by the bacterium Yersinia enterocolitica, which primarily affects the gastrointestinal tract. This zoonotic infection is commonly transmitted through the consumption of contaminated food, particularly undercooked pork, unpasteurized milk, and contaminated water. Symptoms typically include fever, abdominal pain, diarrhea (which may be bloody), and vomiting. In some cases, the infection can mimic appendicitis, leading to misdiagnosis. The disease is more prevalent in children and can lead to complications such as reactive arthritis or, in rare cases, septicemia. Public health measures focus on food safety, proper cooking techniques, and hygiene practices to prevent outbreaks. Surveillance of animal reservoirs, particularly pigs, is crucial as they are the primary source of human infections. The disease is not typically transmitted from person to person, making it essential to identify and control sources of contamination in food production and handling.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between Yersinia enterocolitica and other Yersinia species.
  • Understanding zoonotic transmission and food safety implications.
  • Recognizing clinical presentations that may mimic other gastrointestinal diseases.
  • Documenting specific laboratory findings that confirm diagnosis.

Audit Risk Factors

  • Inadequate documentation of food exposure history.
  • Failure to specify the laboratory confirmation of Yersinia enterocolitica.
  • Misclassification of symptoms that may overlap with other gastrointestinal infections.
  • Lack of detail in patient history regarding zoonotic exposure.
