Toxic effect of aflatoxin, undetermined, sequela

This code signifies the long-term or residual health problems resulting from a past exposure to aflatoxins, where the intent of the exposure (accidental, intentional, assault) cannot be determined. Aflatoxins are toxic compounds produced by certain molds, primarily found in agricultural crops, and their chronic effects can include liver damage, immune suppression, and an increased risk of cancer.

Use this code when documenting conditions such as chronic hepatitis, cirrhosis, or hepatocellular carcinoma that are directly attributable to a prior aflatoxin exposure, and the circumstances of that exposure are unknown or unspecified. This code is appropriate for follow-up care or when the patient presents with sequelae long after the initial exposure.

• Always ensure documentation clearly links the current condition to a past aflatoxin exposure.
• The "S" seventh character indicates a sequela, meaning the residual effect of a previous injury or illness.
• Do not use this code for acute aflatoxin poisoning or when the intent of exposure is known (e.g., accidental, intentional self-harm, assault).
