Across the industry, a year of functional medicine care can run anywhere from around $1,500 to $20,000 or more, and that large spread comes down to one variable: the care model. Cash-pay, concierge, and private practices charging per visit or per program sit at the high end. Membership models sit in the middle. Insurance-accepting models change the math entirely, because eligible medical visits and standard labs can be billed to your plan.

Parsley Health's Complete Care program, for example, is a $150-per-month membership ($1,500 if paid annually, which includes two months free) with a 12-month commitment, and eligible medical visits are billed through insurance for in-network members, with copays and deductibles applying as they would at any doctor's office. Parsley is the first and only functional medicine telehealth practice to accept insurance nationwide, and make root-cause care more financially accessible.

This article breaks the numbers down by model, itemizes what actually drives the cost (visits, labs, supplements), and gives you the questions that keep a year of root-cause care from costing more than it should. All industry figures below come from published sources rather than guesses, because pricing content in this space has a habit of inventing its numbers.

Typical annual costs by care model

There's no standard price for functional medicine, and the field's main training body says so plainly. What exists instead is a set of care models with predictable ranges. The figures below draw on Fullscript's published pricing breakdown and publicly listed practice fees.

Two things to note:The high-end program row describes a real market — destination clinics and longevity-medicine programs price for a concierge experience, and some people want exactly that. The ranges exclude the two most variable line items, labs and supplements, which deserve their own section because they're where budgets most often get away from people.

What drives the cost: visits, labs, and supplements

Visits. Longer appointments are the product. A functional medicine doctor books 60 or more minutes for a first visit, and in a cash-pay model, you're paying for that time directly. In an insurance-accepting model, an eligible medical visit runs through your plan the way a specialist visit would, subject to your copay and deductible.

Lab testing. This is the budget wildcard. Standard blood work (metabolic panels, thyroid, nutrient levels, inflammatory markers) is often billable to insurance when ordered by a licensed clinician. Specialty functional panels are a different story: industry pricing for add-on testing commonly reaches $500 to $2,500 or more per year out-of-pocket, and some of those panels are informational rather than diagnostic. Before agreeing to any test, ask your insurance provider which category it falls into and what it will change about your plan. Our guides to how Parsley approaches testing and common blood test types show what a validated panel covers.

Supplements. Entirely variable, and the place to be most skeptical. A targeted supplement backed by your lab results is money well spent; a 10-bottle protocol recommended before any results exist is a red flag, and it can add $1,000 or more per year to your health care costs. A trustworthy practice recommends less than you expect, ties every recommendation to a finding, and drops what isn't working at follow-up.

Why is most functional medicine cash-pay?

The standard insurance system reimburses short visits and procedures, and the functional medicine model is built on long visits and follow-through, so most independent practices opted out of insurance entirely rather than fit that mold. Even large academic centers that offer functional medicine, like Cleveland Clinic, structure it as a distinct department. The Institute for Functional Medicine describes the landscape accurately:

“Many functional medicine practices are hybrid models, meaning some services may be covered by traditional insurance while others may be fee-for-service.” - Source: Institute for Functional Medicine, patient resources

Parsley Health was built to close that gap: it's the first national functional medicine provider in-network with commercial insurance plans nationwide. Here’s how that works: Insurance plans help cover eligible medical costs: medical visits, lab testing, and prescription medications, with copays and deductibles applying and coverage varying by plan.

The membership fee covers what insurance doesn't reimburse anywhere: clinician partnership, unlimited messaging and support, functional nutrition coaching, a personalized care plan, progress tracking dashboard, a dedicated care coordinator, and the digital platform that securely holds it together. As one member, Kate M., put it on Parsley's insurance page: it was the first functional medicine care she'd found that accepted insurance, which finally made root-cause medicine financially achievable for her.

What does a year at Parsley Health cost?

The Complete Care membership is $150 per month, or $1,500 when paid annually (two months free), with a 12-month commitment. A membership year includes 5 medical visits with a board-certified clinician, 2 functional nutrition coaching sessions, access to advanced diagnostic testing, a targeted care plan covering nutrition, sleep, stress, and movement, a dedicated care coordinator, secure messaging with your care team, and 20% off professional-grade supplements. The cleanest way to understand the cost structure is by who pays for what:

All Parsley programs are HSA/FSA eligible, which lets you pay the membership with pre-tax dollars through a flexible spending or health savings account.

So a realistic annual picture for an in-network member: $1,500 to $1,800 in membership, plus your plan's copays and deductible contributions for medical visits and covered labs, plus whatever targeted supplements or specialty tests you and your clinician decide are worth it. Your out-of-pocket total depends on your specific plan, which is why verifying your coverage is step one, and why we've written a plain-language guide to how functional medicine insurance coverage works.

Is a year of functional medicine worth the cost?

Here's the context most pricing pages skip. Americans already spend heavily on their health each year: KFF's 2024 employer survey put the average annual family premium at $25,572, before deductibles and out-of-pocket costs. And unmanaged chronic conditions carry their own price tag: the American Diabetes Association's economic analysis found people with diagnosed diabetes incur thousands of dollars per year in excess medical costs attributable to the condition. Root-cause care is an investment made against that trajectory.

Who gets the most value per dollar: people with chronic, multi-system symptoms who are already spending on specialists, urgent visits, and supplements without a coordinating plan; people whose insurance is in-network with an accepting practice, which shifts the largest cost category to their existing coverage; and people ready to do the follow-through that makes the plan work. If your needs are simple and your current care is working, a good primary care doctor plus an annual physical may be the right spend, and a credible functional medicine practice will tell you that. Our guide to evaluating providers and our honest take on whether functional medicine is legit can help you pressure-test any practice, including this one.

Five cost questions to ask before you book

Pricing pages give you the headline number. These questions get you to your annual total.

• What does the membership fee cover, and what is billed separately?
• Which services may bill to insurance, and which are paid out of pocket?
• Who verifies my benefits before my first visit?
• How are lab costs handled, and what are my options if my plan covers less?
• How many visits are included, how long are they, and will I see the same clinician each time?

See estimated annual costs for your coverage and care profile on our Cost Breakdown page.

Six ways to keep the annual cost down

• Verify insurance eligibility before you book anywhere, and ask specifically what's billable: visits, labs, or neither.
• Ask which recommended tests are diagnostic and which are informational, and what each will change about your plan. Skip any test without a good answer.
• Route standard labs through insurance when a licensed clinician orders them, and save specialty panels for questions the standard ones can't answer.
• Use HSA or FSA funds; functional medicine visits and eligible programs commonly qualify, which effectively discounts the cost by your tax rate.
• Cap the supplement budget and make every bottle earn its place with a lab result or a symptom change at follow-up.
• Choose annual payment where it's discounted, the way Parsley's annual option includes two months free, if you're confident in the commitment.

Frequently asked questions

How much does functional medicine cost per year?

Industry-wide, roughly $1,500 to $15,000+ per year depending on the model. Per-visit cash-pay care with an MD commonly totals $2,000 to $2,700 in visit fees alone, independent membership clinics often reach $4,000 to $8,000 in year one, and high-end programs run five figures. Insurance-accepting models like Parsley Health pair a $150/month membership with insurance-billed eligible medical visits, so out-of-pocket totals depend on your plan.

Does insurance cover functional medicine?

Insurance doesn't cover 'functional medicine' as a category; it can cover eligible clinical services, meaning medical visits, diagnostics, and prescriptions, when the provider is in-network. Most independent functional medicine practices are cash-pay. Parsley Health accepts commercial insurance plans nationwide for eligible medical visits, with copays and deductibles applying and coverage varying by plan, so verify your benefits first.

How much do functional medicine lab tests cost?

Standard labs ordered by a licensed clinician (metabolic, thyroid, nutrient, and inflammatory panels) are often billable to insurance, leaving you your plan's usual cost share. Specialty functional panels are typically out of pocket, and industry pricing commonly runs $500 to $2,500+ per year for them. Ask whether each test is diagnostic or informational before paying.

Can I use my HSA or FSA for functional medicine?

Usually, yes, for qualified medical expenses, and all Parsley programs are HSA/FSA eligible. Paying with pre-tax dollars effectively reduces the cost by your marginal tax rate. Confirm eligibility with your account administrator, since rules vary by plan and expense type.

Why do some functional medicine programs cost $10,000 or more?

High-end programs bundle concierge access, extensive specialty testing, and destination-clinic experiences, and some overlap with longevity medicine, which prices as a premium category. The price reflects the service model more than the core clinical approach. The root-cause fundamentals (long visits, broad labs, structured diet and lifestyle treatment) are available at a fraction of that through membership and insurance-accepting models.

Is Parsley Health cheaper than other functional medicine options?

The models are structured differently, so compare the published numbers for your situation. Parsley's membership is $150/month with eligible medical visits billed through insurance for in-network members; typical cash-pay practices charge $350 to $950 for an initial visit plus follow-up fees, with everything out of pocket. Your total depends on your plan's copays and deductible, which is why checking eligibility comes first.
