Foodborne Vibrio parahaemolyticus intoxication

This code signifies an acute gastrointestinal illness caused by ingesting food contaminated with Vibrio parahaemolyticus. Patients typically present with watery diarrhea, abdominal cramps, nausea, vomiting, and fever, usually within 24 hours of exposure. The infection is self-limiting in most cases but can be severe in immunocompromised individuals.

Assign this code when documentation confirms a diagnosis of foodborne illness specifically attributed to Vibrio parahaemolyticus. This typically follows laboratory confirmation (e.g., stool culture) or strong epidemiological evidence linking symptoms to consumption of contaminated seafood, particularly raw or undercooked shellfish.

• Ensure the documentation explicitly states "foodborne" and specifies Vibrio parahaemolyticus as the causative agent.
• Do not use this code for other types of Vibrio infections or for food poisoning of unspecified etiology.
• Consider sequencing this code as the primary diagnosis when it is the reason for the encounter.
