1.4 Million DPC Members and Growing. But What Happens When They Need a Specialist?

You run a DPC practice. A patient walks in with chest pain. You spend 45 minutes with them, order the right labs, and determine they need a cardiologist. Then what?

In most DPC practices, “then what” means handing the patient a phone number and sending them back into the insurance maze. The 30-minute visit becomes a two-week wait, a prior authorization, and a $400 copay. Everything your practice stands for gets undone the moment care leaves your building.

This is DPC’s specialist problem. And as the model scales past 1.4 million members nationwide, it’s getting harder to ignore.

The Growth Makes It Urgent

A December 2025 study in Health Affairs found that DPC and concierge practice sites grew 83% between 2018 and 2023. Participating clinicians increased nearly 79% over the same period.

The numbers kept climbing. According to DPC News, DPC now has roughly 2,827 offices and 1.4 million members across the U.S. That puts the model within striking distance of serving 1% of the American population.

The HSA eligibility changes from the One Big Beautiful Bill Act are accelerating this. So is employer adoption, with about 58% of DPC practices now partnering with employers and more than half of all memberships being employer-sponsored.

None of that growth fixes the referral problem. If anything, it makes it worse. More members means more specialist needs, and every one of those referrals is a crack in the DPC experience.

Someone Is Building a Fix

At Hint Summit 2026 in Nashville, UberDoc introduced a specialty referral platform built specifically for DPC practices. The pitch: DPC physicians can refer patients to board-certified specialists across more than 50 specialties with transparent, upfront pricing. No insurance pre-authorization. Same-week availability.

The mechanics are straightforward. A DPC doctor recommends a specialist and shares a direct booking link with the patient, or books during the visit. The patient pays a known price before they walk in the door.

UberDoc is a small company (CSE-listed, still early stage), and the platform is still adding features like preferred specialist lists and referral outcome tracking. This isn’t a finished product being rolled out to thousands of practices tomorrow.

But the fact that companies are building DPC-specific referral infrastructure tells you something about where the market is heading. When DPC was 500 practices, the specialist gap was a nuisance. At nearly 3,000 offices, it’s a structural weakness.

Why This Is Hard to Solve

DPC practices report 20% fewer specialist referrals than traditional fee-for-service practices, along with 66% fewer emergency department visits. Longer visits and smaller panels mean DPC doctors catch things earlier and manage more conditions in-house.

But “fewer” referrals doesn’t mean “no” referrals. Patients still need cardiologists, dermatologists, orthopedic surgeons. And the DPC model has no native answer for what happens when they do.

Some practices negotiate cash-pay rates with local specialists. Others maintain relationships with imaging centers and labs that offer transparent pricing. A few work with organizations like Access Health Direct to coordinate referrals within a direct-pay network.

These are workarounds, not systems. They depend on the individual physician’s connections and the local market. A DPC practice in Austin with three friendly specialists down the street has a different experience than one in rural Tennessee.

What This Means

The specialist referral gap is one of the last major friction points in the DPC model. Membership billing is largely solved. EHRs are catching up. HSA eligibility is settled law. Employer adoption is growing fast.

What’s missing is the connective tissue between primary care and specialty care that works the same way DPC itself works: transparent pricing, direct access, no insurance gatekeeping.

If you’re running a DPC practice today, you might already have a local system figured out for referrals. That works at small scale. But the DPC movement is growing beyond the point where individual relationships can carry the load. The practices, platforms, and networks that figure out specialist access first will have a real advantage as the market pushes toward that 1% threshold and beyond.

The DPC model promised to fix primary care. The next chapter is about fixing everything that happens after primary care.
