Anyone who has navigated the American healthcare system as a patient knows the frustrations well. The three-week wait for an appointment that turns out to be eleven minutes long. The confusing bills that arrive months later. The experience of going through the effort of scheduling and attending a visit only to feel like your actual concerns were never fully addressed. The specialist referral that requires a pre-authorization that takes weeks. And the persistent sense that the system was not designed around what patients need — it was designed around billing codes and reimbursement structures. For many patients, this is not an occasional inconvenience. It is the defining experience of trying to manage their health within a system that consistently makes that harder than it should be.
The direct primary care (DPC) model emerged as a physician-led response to exactly these frustrations. By removing insurance from the primary care equation entirely and replacing it with a transparent monthly membership fee, DPC practices eliminate most of the structural incentives that push conventional medicine toward rushed appointments, limited access, and impersonal care. Physicians in DPC models typically see far fewer patients than those in insurance-based practices, which means more time per patient, faster access, and the ability to actually practice medicine thoughtfully rather than react to billing constraints. More patients are beginning to understand this model and ask whether it might serve them better than what they currently have.
SustainMD operates within a model informed by these principles — providing telehealth-based internal medicine and obesity medicine care with a focus on thoroughness, access, and physician continuity. Dr. Allison Barbee brings her full training in internal medicine and obesity medicine to every patient relationship, not as a transaction gated by insurance approvals, but as an ongoing clinical partnership. For patients in North Carolina, California, Florida, and Maine, SustainMD offers a genuine alternative to the frustrations that conventional care often creates.
What Is Direct Primary Care?
Direct primary care is a primary care delivery model in which patients pay a flat monthly or annual membership fee directly to their physician or practice in exchange for access to a defined scope of primary care services. There are no copays per visit, no claim submissions, no insurance pre-authorizations for routine care, and no billing codes that restrict how a physician spends time with patients. The membership fee covers the relationship — not individual transactions.
DPC practices typically keep patient panels significantly smaller than insurance-based practices. The average insurance-based primary care physician manages a panel of 1,500 to 3,000 patients to generate sufficient revenue per visit. A typical DPC physician manages 400 to 800 patients. This reduction in panel size is what enables same-day or next-day access, longer appointments, direct communication with the physician, and the kind of thorough care that simply is not financially viable in a fee-for-service model.
How DPC Differs from Insurance-Based Primary Care
Access and Availability
In insurance-based primary care, physician access is rationed by the volume demands of a large patient panel. When a practice must generate a certain number of billed encounters per day to remain financially viable, the result is short appointment windows, long waits for non-urgent needs, and the kind of reactive rather than proactive care that leaves patients feeling underserved. DPC practices, by contrast, are financially sustainable at smaller panel sizes, which allows physicians to be genuinely available — not just technically accessible.
Patients in DPC practices often have direct communication access to their physician through secure messaging or phone calls, can schedule appointments the same day or next day for non-emergency concerns, and receive longer appointments that accommodate thorough discussion of complex issues.
Time per Patient
This is where the difference becomes most tangible for patients. In a typical insurance-based model, a primary care appointment might realistically allocate eight to fifteen minutes of physician time once administrative overhead is accounted for. DPC appointments are routinely thirty to sixty minutes. This is not just a comfort difference — it is a clinical difference. Chronic disease management, metabolic health evaluation, complex medication reviews, and meaningful conversations about lifestyle and treatment options require time. When the appointment model systematically prevents adequate time, clinical quality suffers.
Cost Transparency
One of the most consistent complaints about insurance-based healthcare is the complete opacity of cost until bills arrive — sometimes months after service. DPC replaces this with a simple, predictable monthly fee. Patients know exactly what they are paying. For procedures and tests not included in the membership, DPC practices typically have wholesale pricing arrangements that produce significantly lower out-of-pocket costs than insurance-billed rates for labs and common medications.
Preventive and Proactive Care
Insurance-based primary care is reimbursed primarily for treating problems, which creates structural incentives toward reactive rather than preventive care. DPC practices, free of this reimbursement structure, are better positioned to invest physician time in proactive monitoring, metabolic surveillance, and early intervention that prevents problems before they become expensive and difficult to treat.
What DPC Does Not Cover
Direct primary care covers primary care services, not specialty care, hospitalizations, emergency care, or complex procedures. Patients in DPC models typically also carry a high-deductible health insurance plan or health-sharing arrangement that protects them from catastrophic costs. DPC is not a replacement for insurance — it is a replacement for the primary care component that insurance often handles poorly. The combination of a low-cost catastrophic plan and a DPC membership often produces better access to primary care and lower total healthcare spending than a comprehensive insurance plan alone.
Is DPC Right for You?
DPC tends to provide the most value for patients who currently use primary care regularly but feel underserved by rushed appointments and poor access. It is also well-suited for patients managing chronic conditions who benefit significantly from more physician time, more consistent follow-up, and more proactive care. Patients with complex metabolic health needs — insulin resistance, obesity, prediabetes, metabolic syndrome — are an especially natural fit because these conditions require the kind of thorough evaluation and ongoing management that insurance-based primary care routinely does not provide.
DPC may be less appropriate for patients with complex multi-specialty needs that require extensive coordination with specialist care, or for those whose healthcare is very infrequent and the monthly membership fee would exceed what they would otherwise pay. An honest conversation with a DPC-informed physician can help you assess whether the model fits your situation.
Virtual DPC: Combining Access with Convenience
The combination of the DPC model with telehealth delivery is a natural evolution that removes the remaining access barrier of geographic proximity. Virtual DPC practices provide all the advantages of the DPC model — physician time, direct access, personalized care — without requiring the patient to live near the practice’s physical location. For patients in rural areas, those with demanding schedules, or anyone who has struggled to find quality primary care that is both thorough and accessible, virtual DPC represents a genuinely different option.
SustainMD operates at this intersection — telehealth-delivered, physician-led, focused on the metabolic and chronic disease management needs that benefit most from the DPC model’s emphasis on time and access.
Conclusion
The frustrations many patients feel with insurance-based primary care are not random — they are structural outcomes of a system built around billing codes and volume rather than clinical relationships and patient needs. Direct primary care addresses these structural problems by realigning the incentives around what actually produces better health outcomes: access, time, continuity, and thoroughness. It is not the right model for everyone, but for patients who currently feel underserved by their primary care experience and have predictable primary care needs, it is worth understanding seriously. Dr. Allison Barbee at SustainMD is happy to discuss whether this approach to care is a good fit for your specific situation.

Frequently Asked Questions
1. What is direct primary care and how does it work?
Direct primary care is a membership-based model in which patients pay a monthly fee directly to their physician for access to primary care services. There are no per-visit copays, no insurance billing for routine care, and no claim submissions — just a direct financial relationship that supports a smaller patient panel and more physician time per patient.
2. Do I still need health insurance if I join a DPC practice?
Yes. DPC covers primary care only. Most DPC patients also carry a high-deductible health plan or health-sharing arrangement for specialty care, hospitalizations, and emergencies. The combination typically provides better primary care access and lower total costs than comprehensive insurance alone.
3. How much does direct primary care typically cost?
Monthly membership fees vary by practice, patient age, and services included, but typically range from $50 to $150 per month for adult patients. This covers the primary care relationship — not labs, imaging, or specialist referrals, though many DPC practices offer wholesale pricing on these services.
4. What services are included in a DPC membership?
This varies by practice, but typically includes unlimited primary care visits (virtual or in-person), direct physician communication, chronic disease management, medication management, and preventive care. Some practices include certain lab work and generic medications in the membership fee.
5. Is direct primary care the same as concierge medicine?
They share some similarities but differ in scope and cost. Concierge medicine typically operates alongside insurance billing and may include specialty services, usually at a higher membership cost. DPC explicitly removes insurance from the primary care equation and tends to be more accessible price-wise.
6. Can I use a DPC practice for metabolic health and weight management?
Yes. DPC is particularly well-suited for metabolic health management because these conditions benefit enormously from the physician time, thorough lab evaluation, and consistent follow-up that DPC makes possible. SustainMD specializes in exactly this type of care.
7. What are the advantages of virtual DPC compared to in-person DPC?
Virtual DPC removes the geographic constraint, allowing patients anywhere in a state to access quality physician-led primary care without commuting to an office. It offers the same access, continuity, and physician time advantages as in-person DPC while adding the convenience of telehealth.
8. Is DPC available in rural areas?
Virtual DPC is accessible to patients in rural and suburban areas regardless of proximity to a physical practice. SustainMD serves patients across North Carolina, California, Florida, and Maine through telehealth, making physician-led metabolic and primary care accessible outside major metro areas.
9. How does direct primary care handle specialist referrals?
DPC physicians can refer patients to specialists as needed. Some DPC practices have established relationships with specialists at negotiated rates; others work within existing insurance networks. The DPC relationship does not limit specialist access — it improves the quality and thoroughness of the primary care component that generates and coordinates referrals.
10. How do I know if DPC is the right model for my healthcare needs?
DPC tends to provide the most value for patients who use primary care regularly, manage chronic conditions, and feel underserved by rushed conventional care. A consultation with a DPC-informed physician can help you assess whether the model, cost structure, and services align with your specific situation and health needs.
