Toxic effect of mycotoxin food contamnt, undet, sequela

This code signifies a long-term or late-occurring health problem resulting from exposure to an unspecified mycotoxin food contaminant. The original poisoning event is no longer acute, and the specific mycotoxin responsible for the toxic effect could not be determined. This code is used when the patient presents with residual symptoms or conditions directly attributable to that past exposure.

Use this code when documenting a chronic condition or sequela (e.g., organ damage, neurological deficits, chronic fatigue) that is definitively linked to a past toxic exposure from an unidentified mycotoxin in food. This applies when the acute phase of the poisoning has resolved, and the patient is now being treated for the lasting effects. It is appropriate when the specific mycotoxin cannot be identified, and the intent is to capture the long-term impact.

• Requires a seventh character 'S' to indicate sequela, meaning the residual effect of a past condition.
• Do not use for acute poisoning; refer to codes for initial encounters or subsequent encounters for active treatment of the poisoning itself.
• Always sequence this code after the code(s) for the specific manifestation(s) of the sequela (e.g., chronic kidney disease, neuropathy).
