What a Membership Model Buys, and What It Cannot Include

Answer first: a monthly fee is not one thing

A recurring charge attached to care can be doing any of three jobs, and they are not variations on a theme.

It can be a retainer that buys access to a clinician. It can be a gate you pay through before a price is offered to you. Or it can be a bundle in which the fee and the medication are the same charge.

Those three arrangements answer different questions when something goes wrong. Stopping the fee ends a relationship in the first, ends an eligibility in the second, and ends a supply in the third.

Federal law has now written down what the first one is. That definition is the most precise ruler available for reading the other two.

Federal tax law defines the retainer model

A provision of the Internal Revenue Code defines a direct primary care service arrangement. It was added by a public law enacted in July 2025, and the section's own effective-date note applies the change to months beginning after December 2025.

The definition has three parts and each one is load-bearing. The care provided must be medical care as the Code defines it. It must consist solely of primary care services. And it must be provided by primary care practitioners as the Social Security Act defines them.

Then comes the payment condition. The sole compensation for that care must be a fixed periodic fee.

Read the word solely twice. It appears once about the services and once about the compensation, and it is doing the same work both times. An arrangement that adds a second kind of service, or a second kind of charge, is outside the definition.

There is a ceiling as well. The statute caps the aggregate monthly fees for all such arrangements for one person, and doubles that ceiling where an arrangement covers more than one individual. The cap is written as a dollar figure in the law and carries an inflation adjustment in later taxable years.

The exclusion that matters most here

The same provision lists what primary care services do not include, and the middle item is the one that reshapes this market.

Three things are named. Procedures that require the use of general anesthesia. Prescription drugs, other than vaccines. And laboratory services not typically administered in an ambulatory primary care setting.

So a fixed periodic fee that meets this definition is buying clinician access and it is definitionally not buying your medication. The statute puts prescription drugs outside the fee rather than leaving it to the parties.

That single clause separates two arrangements that look identical from the outside. A retainer for primary care and a subscription that supplies a drug are different structures, and only one of them is described here.

The provision also directs that regulations or other guidance be issued on how the clause applies, after consultation between two federal departments. The definition exists now; its edges are still being drawn.

Why a tax definition is a useful ruler for a cash-pay program

The definition binds nobody who is not claiming its treatment. A program that falls outside it is not doing anything wrong, and most programs in this category are not attempting to fall inside it.

Its value is that it forces the question a marketing page can leave open. What, exactly, is the fee compensation for.

The statute's own answer is a relationship with a primary care practitioner and nothing else, priced as one periodic amount. Where a fee is buying something different, the difference is worth naming.

One further detail is worth knowing because it explains the shape of these arrangements. The provision states that such an arrangement is not treated as a health plan for the purpose of a specific eligibility test elsewhere in the Code.

That is a tax classification, not a medical one. It does mean the law regards the retainer as a way of buying care rather than a way of buying coverage, which is exactly the distinction people find confusing in practice.

What concierge and retainer arrangements trade away

The gain is access, and it is a real one. Paying a periodic amount for a relationship generally buys a shorter path to the same clinician and more time inside a visit.

The first trade is scope. An arrangement built on this definition covers primary care services, and it stops where the definition stops. Anything requiring general anesthesia, anything that is a prescription drug, and laboratory work outside the ordinary ambulatory range sit outside the fee.

The second trade is that the fee runs whether or not you use it. A periodic charge is not consumption-based, which is the point of a retainer and also its cost.

The third trade is that a single relationship becomes a single point of failure. Where the arrangement ends, the access ends with it, and access was the thing being bought.

None of that argues against the model. It argues for reading the fee as a purchase of something specific rather than as a general upgrade.

Reading a recurring fee without guessing

Start with the sequence. A fee charged before a price is shown to you is functioning as a gate, whatever it is called on the page.

Then look at what stops when the fee stops. A program that says the medication continues is describing separate purchases; one that says everything ends is describing a bundle.

Then look at who the fee buys. A retainer names a practitioner or a category of practitioner. A platform fee names a service.

And look at whether the recurring amount is described as the sole charge for the care. That phrase is the hinge of the statutory definition, and a program that is not the sole charge for anything is a different structure with a similar name.
