Physician-led, root-cause care is now in-network for 150 million Americans through health insurance plans in all 50 states

Parsley Health was the first telehealth provider to offer functional medicine nationwide, and is now the first to offer it through the mainstream healthcare insurance system. Starting today, Parsley's physician-led, root-cause care is available nationwide through in-network insurance plans, expanding access to 150 million people through their existing health insurance benefits.

Parsley now accepts hundreds of major insurance plans, including Aetna, Cigna, UnitedHealthcare, BlueCross BlueShield, Humana, and Centene. Insurance may cover eligible medical costs such as provider visits, diagnostic testing, and clinician-directed prescriptions. This milestone reflects a cultural shift in demand for more personalized, comprehensive, integrated medicine.

"When I founded Parsley Health a decade ago, my mission was to make high-quality, evidence-based functional medicine and longevity care accessible to everyone. So, going in-network nationwide was the ultimate goal — and I'm proud that Parsley is the first to make this a reality," said Dr. Robin Berzin, Founder and CEO of Parsley Health. "Functional medicine has historically been expensive, elusive, and inconsistent. Parsley has solved all three. We're giving millions of people easy access to care that both treats complex conditions sustainably and optimizes their health over time."

Parsley first introduced in-network coverage in New York in 2023 through a partnership with Mount Sinai Hospital, followed by an expansion in California. Today's nationwide rollout represents a significant step towards making proactive, preventative medicine the default option in our nation's healthcare system.

The case for root-cause functional medicine

Today, 3 in 4 American adults live with at least one chronic condition, and more than 4 in 10 with two or more. Chronic disease now accounts for 90% of the nation's $4.9 trillion in annual healthcare spending.¹ This shows how the traditional healthcare system was built to manage symptoms and handle acute care, rather than address underlying causes at the root and optimize for long-term health.

As a result, consumers have increasingly sought out alternative options: the global health and wellness economy now stands at $6.8 trillion and is projected to approach $9.8 trillion by 2029,² with 84% of U.S. consumers naming wellness a top or important priority.³ This has fueled the explosive growth of integrative and functional medicine — a U.S. market expected to grow from $28.65 billion to over $229 billion by 2033.⁴

How in-network functional medicine works

Parsley's care model was built to meet that need. Its board-certified clinicians, specially trained in functional medicine, take a systems-based approach to understand how interconnected factors — from hormones and metabolism to gut health and inflammation — contribute to conditions like fatigue, autoimmunity, metabolic syndrome, infertility, and GI dysfunction. The results are measurable with 89% of Parsley members reporting significant symptom improvement or complete resolution within their first year of care, based on the Parsley Symptom Index, a proprietary outcomes tool developed in alignment with FDA guidelines and validated in peer-reviewed research.

With insurance serving to offset or cover eligible medical costs, program fees are also reduced to $150/month (or $1,500 if paid annually), which supports Parsley's full experience: a dedicated five-person care team — including a board-certified clinician, functional medicine nutrition coach, and RN care coordinator — clinical interpretation of lab testing and diagnostics, access to specialty testing, five provider visits annually, integrated progress tracking, ongoing support, and more. Typical out-of-pocket costs for comparable functional or concierge medicine can range from $500-1,500+ for a single visit with annual programs ranging from $5,000 to $20,000+. Parsley has solved for both the rushed, reactive, and fragmented constraints of conventional medicine and the expensive, inaccessible, out-of-network model of other options.
