Functional Medicine
Root-cause investigation and personalized treatment plans for complex, chronic health conditions
Functional Medicine is the specialty focused on root-cause investigation and personalized treatment plans for complex, chronic health conditions. OpenDoc keeps the common visit types visible so patients can compare the care path before they book. Transparent pricing on this page currently ranges from $150 to $1,000 across 12 common visit types. Functional medicine practitioners use systems-based, root-cause analysis to identify and address the underlying drivers of chronic disease rather than merely treating symptoms. By integrating advanced laboratory testing, nutrition science, and personalized treatment protocols, functional medicine offers a comprehensive approach for patients with complex conditions that conventional medicine has failed to resolve. OpenDoc provides transparent cash pricing on functional medicine services starting at $150 — a specialty that insurance almost never covers, making upfront pricing essential.

Cash-pay context
Why pricing transparency matters here
Functional medicine is an almost entirely cash-pay specialty — insurance does not cover extended consultations, advanced specialty lab panels, or personalized nutrition protocols. This means every functional medicine patient is already a cash-pay patient, making transparent upfront pricing on OpenDoc the natural standard for this specialty.

Why subspecialty matters
Why OpenDoc separates these care paths instead of collapsing them
Focused training matters
Specialties often branch into narrower care paths. Seeing them clearly helps patients choose providers with training that actually matches the problem.
Prices match the care path
A sports medicine visit, a spine evaluation, and a tumor consult are not the same visit. OpenDoc keeps pricing attached to the path, not just the umbrella specialty.
Less guesswork before booking
Patients should understand the likely route before they see provider cards. That lowers false starts and makes the next step into provider search feel clearer.
Better provider fit
This page keeps specialty, subspecialty, common visit types, and price context aligned so users can move into provider selection with more confidence.
