Does Insurance Cover Functional Medicine?
Functional medicine is rarely covered as a category, but individual services may be covered depending on the practitioner's base credential. If your functional medicine doctor is an MD or DO, standard office visits may be billed to insurance. However, specialized functional medicine labs, supplements, and extended consultations are typically not covered.
Medicare Coverage
No specific Medicare coverage for 'functional medicine.' However, if the provider is a licensed MD/DO, standard E&M (evaluation and management) visits can be billed to Medicare for diagnosed conditions. Specialty labs, supplement protocols, and lifestyle coaching are not covered.
Eligible Providers
Private Insurance Coverage
Private plans may cover E&M visits with functional medicine MDs/DOs using standard billing codes. Extended visit codes (99354-99355) are sometimes covered. Specialized functional lab panels ($300-3,000+) and supplement recommendations are virtually never covered by insurance.
What about Medicaid?
Medicaid coverage for functional medicine varies by state. Some states cover it under managed care plans while others do not. Contact your state Medicaid office or check your plan's benefits guide.

How to Check Your Coverage
- 1
Call the number on your insurance card
Ask: "Is functional medicine a covered benefit under my plan?" Get the answer in writing or note the reference number.
- 2
Ask about prior authorization
Some plans require pre-approval before treatment. Ask if a referral from your primary care doctor is needed.
- 3
Verify provider network status
In-network providers will cost significantly less. Ask your insurer for a list of covered providers in your area.
- 4
Understand your cost share
Ask about your copay, coinsurance, and deductible for this service. Out-of-network benefits may still apply.
- 5
Check HSA/FSA eligibility
Even if insurance doesn't cover functional medicine, you may be able to use pre-tax HSA or FSA funds. Get a letter of medical necessity from your doctor.
