Re: Insurance Billing for Functional Nutrition Lab Tests

To Whom It May Concern,

I recommend the following tests to assist me in supporting our shared client/patient.

These lab tests are helpful to me in detemining proper dietary, lifestyle and nutraceutical recommendations. 

Since I do not conduct billing through health insurance to cover the cost of lab testing, when lab testing might coincide with a medical diagnosis, I recommend my clients discuss ordering the lab tests through their medical doctors so that insurance can cover the cost.
