Does Medicare Cover Mycotoxin Testing?

Although Medicare does not specifically mention mycotoxin testing, Medicare Part B may cover mycotoxin tests if a doctor deems it medically necessary.
Mycotoxins are toxic compounds that certain types of molds and fungi produce. They occur naturally but can contaminate food and some indoor environments.
Common mycotoxins include:
Aflatoxins: Different types of aflatoxins grow in soil, rotting vegetation, hay, grains, cereals, corn, sorghum, wheat, rice, soybeans, peanuts, sunflower seeds, cotton seeds, chili and black pepper, coriander, turmeric, ginger, pistachio nuts, almonds, walnuts, coconuts, and Brazil nuts.
Ochratoxins: These types can contaminate foods, including cereals and cereal products, coffee beans, dry vine fruits, wine, grape juice, spices, and licorice.
Patulin: These can be found in rotting fruit, with the main dietary sources found in apples and apple juice made from affected fruit.
Fusarium fungi: These are often found in cereal crops, wheat, oats, and maize.
Tests for mycotoxins and Medicare coverage
A doctor or healthcare professional may order tests to look for signs of myotoxicity, such as a blood serum test, skin prick testing for particular mold allergens, a bronchial challenge test, or urinalysis.
Medicare Part B will typically cover these tests as long as they are medically essential. There are no out-of-pocket costs for these clinical diagnostic lab tests.
Symptoms of mycotoxicity
Mycotoxins can cause mild to more serious health conditions and some of the symptoms you may experience can include:
coughing
wheezing
nasal congestion
skin rashes
watery eyes
itching
muscle aches
fatigue
liver damage
Additionally, people with weakened immune systems may experience heightened sensitivity to mycotoxins.
Reducing the risk of mycotoxins
You can minimize health risks related to mycotoxins by:
Inspecting your food items: Inspect whole grains like corn, wheat, rice, dried figs, and nuts, including peanuts, Brazil nuts, pistachios, walnuts, almonds, coconuts, and hazelnuts. Throw out foods that look moldy, have discoloration, or are shriveled.
Ensuring freshness of food: Buy grains and nuts that are as fresh as possible.
Taking care of food storage: Ensure your foods are stored correctly by keeping them dry, not too warm, and free from insects. Try not to keep foods for long periods before you use them and adhere to packing 'use by' dates.
Diversifying your diet: Eating a variety of foods can help reduce your exposure to mycotoxins.
