Viral and other specified intestinal infections

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015

Code Description

ICD-10 B08 is a billable code used to indicate a diagnosis of viral and other specified intestinal infections.

Key Diagnostic Point:

B08 encompasses a variety of viral infections that primarily affect the intestinal tract, leading to symptoms such as diarrhea, vomiting, abdominal pain, and fever. Common viral pathogens include rotavirus, norovirus, and adenovirus, which are particularly prevalent in pediatric populations. Rotavirus is a leading cause of severe gastroenteritis in children, while norovirus is notorious for outbreaks in crowded settings like cruise ships and nursing homes. The clinical presentation can vary from mild, self-limiting illness to severe dehydration requiring hospitalization. Vaccination plays a crucial role in preventing rotavirus infections, with the rotavirus vaccine recommended for infants. Complications from viral intestinal infections can include dehydration, electrolyte imbalances, and in rare cases, post-infectious irritable bowel syndrome. Accurate coding for B08 requires careful consideration of the specific viral agent involved and the clinical context of the infection.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of viral pathogens that can cause similar symptoms
  • Need for specific documentation of the viral agent
  • Differentiation from bacterial and parasitic infections
  • Potential for complications requiring additional coding

Audit Risk Factors

  • Inadequate documentation of the specific viral agent
  • Misclassification of viral infections as bacterial or parasitic
  • Failure to document complications such as dehydration
  • Inconsistent coding practices across providers
