Toxic effect of mycotoxin food contamnt, undetermined, subs

This code signifies a toxic reaction to a mycotoxin, other than aflatoxin or ergot alkaloids, ingested through contaminated food. The specific mycotoxin is not identified, and the encounter is for follow-up care after the initial diagnosis and treatment.

Apply this code for patients presenting for subsequent evaluation or management of symptoms related to a previously diagnosed, unspecified mycotoxin food poisoning. This is appropriate when the initial acute phase has passed, and the patient is receiving ongoing care for residual effects or monitoring.

• Ensure the documentation clearly indicates a "subsequent encounter" for the mycotoxin toxicity.
• Confirm that the mycotoxin is not specified as aflatoxin (T64.0-) or ergot alkaloids (T64.1-).
• Always look for a more specific mycotoxin code if the type is identified in the medical record.
