Botulism food poisoning

This code represents a severe, potentially fatal form of foodborne illness caused by toxins produced by Clostridium botulinum. It specifically identifies botulism resulting from ingestion of contaminated food, leading to flaccid paralysis. The neurotoxins block acetylcholine release at neuromuscular junctions, causing muscle weakness and respiratory failure.

Use this code for patients presenting with symptoms of botulism directly linked to food consumption, such as blurred vision, dysphagia, muscle weakness, and respiratory distress. Documentation should clearly indicate a history of ingesting suspected contaminated food and clinical findings consistent with botulinum neurotoxin poisoning.

• Distinguish from infant botulism (005.81) or wound botulism (005.89), which have different etiologies.
• Always sequence as the primary diagnosis when it is the reason for the encounter.
• Ensure documentation specifies "food poisoning" or "foodborne" to support this specific subcategory.
