DPC Isn't Concierge Medicine. A Law Firm Just Spelled Out Why.
You’ve probably heard someone call DPC “concierge medicine.” Maybe a patient. Maybe a colleague. Maybe a reporter who couldn’t be bothered to check. The two models share surface-level DNA: membership fees, smaller panels, longer visits. But legally, they’re different animals. And a national law firm just published a primer that makes the case clearly.
What Nossaman Got Right
Nossaman LLP, a law firm with a national healthcare practice, published “Understanding Concierge Medicine: A Practice-Level Overview” this week. The piece walks through the legal landscape of membership-based medicine, covering everything from corporate practice rules to membership agreement requirements.
The timing matters. The broader membership medicine market hit roughly $7.35 billion in 2024, according to the article, with projections showing 10% or more annual growth that could double the market by 2030. DPC membership alone grew 837% from 2017 to 2025. More physicians are considering the model than at any point in the last decade. And as the market scales, the legal framework isn’t something you figure out later.
Two Models, Two Legal Frameworks
The core distinction is about insurance.
A hybrid concierge practice charges patients a retainer fee for enhanced access. Same-day appointments, longer visits, direct physician communication. But the practice still bills insurance and Medicare for covered services. Patients pay more for the experience. The insurance billing stays.
A Direct Primary Care practice skips insurance entirely. Patients pay a periodic fee that covers a defined scope of primary care services. No claims. No billing codes. No pre-authorizations.
The legal consequence of that split is significant. When a practice bills insurance, it stays within the existing regulatory framework of CMS compliance, coding requirements, and payer contracts. When it doesn’t, the question becomes whether the practice is offering something that looks like insurance to state regulators.
Most states have answered that question by passing DPC-specific legislation that exempts direct primary care agreements from insurance regulation. But not every state has acted. In states that haven’t, the legal status of a cash-only membership practice can be ambiguous. The Nossaman analysis flags this as one of the most important considerations for any physician evaluating the model.
The Corporate Practice Problem
The article also highlights an issue that many physicians don’t think about until it’s too late: the Corporate Practice of Medicine doctrine.
In states like California, the law is blunt. California Business and Professions Code § 2400 says that corporations and other artificial entities “shall have no professional rights, privileges, or powers.” Only licensed physicians can own and control medical practices. A non-physician investor, management company, or corporate entity can’t make clinical decisions or own the practice entity.
This matters for DPC physicians who get approached by companies offering to handle operations, billing, or practice management in exchange for equity or control. The doctrine doesn’t prohibit administrative support. Practices routinely use Management Services Organizations for non-clinical functions. But clinical decision-making authority has to stay with a licensed physician.
With private equity interest in DPC growing, understanding where that line falls is practical, not theoretical.
Get the Agreement Right
Nossaman’s primer outlines what a legally sound membership agreement needs to include:
- Covered services and what gets billed separately
- A clear statement that the membership is not health insurance and does not satisfy federal coverage mandates
- Termination terms, including advance notice requirements and refund policies
- Patient obligations regarding payment and compliance
- Third-party payment provisions, which are increasingly relevant as employers fund more DPC memberships
In states with DPC legislation, these disclosures are typically required by statute. In states without specific DPC laws, a comprehensive membership agreement is the practice’s primary legal protection against being classified as an unauthorized insurance product.
What This Means
If you’re running a DPC practice, the distinction between your model and concierge medicine isn’t semantic. It determines which regulations apply, how your membership agreement needs to be structured, and what happens when a state regulator comes asking questions.
If you’re considering starting a practice, this is the legal homework you do before signing a lease. Understanding the Corporate Practice of Medicine doctrine in your state, structuring your membership agreement correctly, and confirming whether your state has specific DPC legislation will shape everything from entity formation to patient onboarding.
The Nossaman analysis covers the broader concierge landscape, not just DPC. But the legal framework it describes is the same framework DPC physicians operate within. As the membership medicine market grows toward what could be a $15 billion industry by decade’s end, more physicians will face these legal questions for the first time. The ones who get the answers before they open their doors will have one less thing keeping them up at night.
