Toxic effect of mycotoxin food contamnt, undetermined, init

This code signifies a patient presenting with adverse health effects due to exposure to mycotoxins, excluding aflatoxin, that were ingested through contaminated food. The specific mycotoxin involved is not identified, and the intent of the exposure (e.g., accidental, intentional) is unknown.

Use this code when a patient exhibits symptoms consistent with mycotoxin poisoning from food, but the exact mycotoxin is not specified in the medical record. This applies to initial evaluations and treatments for such an exposure where the circumstances are undetermined.

• Ensure documentation clearly states "undetermined" for the intent of exposure.
• Only use for initial encounters; subsequent care would require a different seventh character.
• If the specific mycotoxin is identified, a more precise code from the T64.8- series should be used.
