Toxic effect of harmful algae and algae toxins, asslt, init

This code signifies a patient presenting with adverse health effects resulting from exposure to harmful algae or their toxins, specifically when the exposure was intentionally inflicted by another person. These effects can range from gastrointestinal distress and skin irritation to neurological symptoms, depending on the specific toxin and exposure level.

Apply this code when documentation clearly indicates a patient's illness or injury is due to toxic exposure from algae or algal toxins, and the circumstances surrounding the exposure are identified as an assault. This would include scenarios where an individual deliberately contaminates food, water, or a person with harmful algae or their byproducts.

• Ensure the documentation explicitly states "assault" or similar language indicating intentional harm by another party.
• Verify the specific type of toxic effect is documented to support the diagnosis.
• Confirm this is the initial encounter for the assault-related toxic effect; subsequent encounters will require different seventh characters.
