Unfortunately, most of this approach will not be covered by typical insurances. Regular labs (not specialty labs) are usually covered by your insurance. However, the office visit fees, supplements and specialty labs are typically not covered. You can submit superbills to go toward your out-of-network deductible. There are healthcare sharing plans that may cover functional medicine services. This coverage must be obtained prior to getting any new diagnoses, as previous conditions are excluded from coverage. This might be a money-saving option! Some examples are Medi-Share and Samaritan Ministries. You would have to thoroughly vet any option to ensure they would cover your needs.
