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 decide they need a cardiologist. Then what?

If you’re doing DPC well, you call a specialist you trust. You send your notes instead of a terse e-fax. You follow up on what the cardiology visit turned up and make sure recommendations don’t get dropped. That part of the referral is where DPC quietly runs circles around 12-minute insurance practices.

What you can’t fix from inside your exam room is the other half. The prior auth. Three-week waits. A $400 copay. Pricing nobody can quote until the bill lands. That’s not a DPC failure. It’s the specialist layer still running on insurance-based rules your practice doesn’t control.

That’s DPC’s specialist problem. The coordination part is solved. The cost and access part isn’t. And as the model scales past 1.4 million members nationwide, that gap is 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. And it isn’t trying to replace the coordination DPC physicians already do. It’s attaching cash-pay specialist access to it.

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 the Cost Layer Lags the Coordination

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.

When referrals do happen, DPC doctors aren’t handing patients a phone number and disappearing. Forward Family Medicine, a DPC practice in Pennsylvania, walks through the standard approach in a detailed piece on how DPC handles referrals: warm handoffs to specialists the physician trusts, detailed referral packages instead of terse e-faxes, tracking of results and medication changes, and advocacy when wait times need to be shortened. That coordination is real work, and it’s one of the things patients are actually paying for.

The part DPC can’t solve from inside the exam room is the specialist’s bill. That still runs through the patient’s insurance, usually a high-deductible plan. Some practices negotiate cash-pay rates with local specialists. Others route patients through direct-pay networks like Access Health Direct. These help, but they depend on the individual physician’s rolodex 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 remaining specialist friction is one of the last major gaps in DPC. Membership billing is largely solved. EHRs are catching up. HSA eligibility is settled law. Employer adoption is growing fast.

What’s still missing is a repeatable way to pair the coordination DPC doctors already do with specialist pricing that works the same way DPC itself does: transparent, direct, no insurance gatekeeping.

If you’re running a DPC practice today, you probably already have the coordination side dialed in. A handful of trusted specialists. A couple of cash-pay imaging centers. A clear handoff process that doesn’t leave patients guessing. That’s real infrastructure, and it’s most of the battle. What it doesn’t give you is predictable pricing every time a patient needs care outside your practice. That’s the last mile.

The DPC model already fixed how primary care feels. The next chapter is making the specialist layer feel the same way.
