The United States is facing a primary care physician shortage driven by a combination of low pay, crushing paperwork, capped training programs, and surging demand from an aging population. The AAMC projects the country could be short up to 86,000 physicians by 2036, and over 100 million Americans already live in areas formally designated as primary care shortage zones.
No single factor created this problem. It’s the result of financial incentives that steer medical graduates away from primary care, a payment system that undervalues the work, and structural limits on how many new doctors can be trained each year.
The Pay Gap Pushes Graduates Toward Specialties
Primary care physicians earn significantly less than their specialist colleagues. In 2023, primary care doctors (family medicine, general internal medicine, and general pediatrics) earned an average of $262,000 per year, while specialists averaged $382,000. That’s a $120,000 annual gap, and it compounds over the course of a career into millions of dollars in lost earnings.
This gap matters enormously when you consider the debt new doctors carry. The class of 2024 graduated with a median education debt of $205,000, and the mean was even higher at $212,341. When you owe that much money, choosing a specialty that pays $120,000 more per year isn’t just appealing. For many graduates, it feels financially necessary. The result is that fewer and fewer medical students choose primary care residencies, even as the need for primary care doctors grows.
A Payment System That Undervalues Primary Care
The pay gap isn’t just a market quirk. It’s baked into how Medicare, the largest payer in American healthcare, reimburses doctors. Medicare pays significantly more for clinical procedures like surgeries, imaging, and diagnostic tests than it does for the non-procedural work that makes up most of primary care: office visits, preventive care, patient education, and coordinating treatment across multiple providers.
MedPAC, the congressional advisory body on Medicare, has flagged this as a systemic problem. Procedures also tend to get cheaper over time as technology improves, but the time a primary care doctor spends talking through a patient’s chronic conditions, adjusting medications, and coordinating referrals doesn’t become more efficient. The imbalance encourages doctors of all specialties to prioritize more profitable procedures over high-value but lower-paying services like prevention and care coordination. For primary care physicians, whose entire practice revolves around these lower-paying services, the financial penalty is constant.
Paperwork That Rivals Patient Time
Even doctors who choose primary care are burning out at alarming rates, and electronic health records are a major reason why. For a typical 30-minute primary care visit, physicians spend an average of 36.2 minutes on the associated electronic health record work. That means for every half hour spent with a patient, a doctor spends more than half an hour clicking through digital forms, entering notes, and managing documentation. Some physicians in the top quartile spend nearly 46 minutes per visit on records alone.
This isn’t just frustrating. It’s a direct driver of burnout and early retirement. When the administrative burden of practicing medicine exceeds the time spent actually practicing it, experienced physicians leave the field sooner, and younger doctors are less inclined to enter it.
A Training Pipeline With a Hard Cap
Even if more medical students wanted to become primary care doctors, the system can only train so many. Medicare funds the majority of physician residency training in the United States, and the number of residency slots each hospital can fill has been capped for decades. Without a residency, a medical school graduate cannot practice independently, so these caps directly limit the supply of new physicians.
Congress took a modest step in 2021, authorizing 1,000 new Medicare-funded residency positions to be distributed over at least five years. As of September 2025, only 600 of those positions had been allocated. About half of the hospitals that received new slots applied to train residents in primary care, which is encouraging but far short of what’s needed. Stakeholders have also noted that hospitals in the most underserved areas were sometimes disadvantaged by the distribution process, and the up-front costs of launching new residency programs deterred some hospitals from applying at all.
Demand Is Growing Faster Than Supply
On the other side of the equation, the number of people who need primary care is rising sharply. The U.S. population aged 65 and older grew by 38.6% between 2010 and 2020, reaching 55.8 million. That was the fastest growth rate for this age group since the 1880s. Older adults use primary care far more frequently than younger people, managing multiple chronic conditions that require regular visits, medication adjustments, and specialist referrals.
At the same time, the physician workforce itself is aging. In 2018, 43% of active physicians were 55 or older and likely to retire within 10 years. As these doctors leave practice, they aren’t being replaced fast enough. The combination of rising demand and shrinking supply is what makes the shortage projections so stark.
Geographic Gaps Make It Worse
The shortage isn’t evenly distributed. As of early 2026, the federal government had designated 8,789 primary care Health Professional Shortage Areas across the country. More than 101 million people live in these zones, roughly a third of the U.S. population. Rural communities, low-income urban neighborhoods, and tribal areas are disproportionately affected. A medical school graduate in a major city has little financial incentive to relocate to a rural county where patient volumes may be lower and infrastructure is limited, so these gaps tend to persist and widen over time.
Can Nurse Practitioners and PAs Fill the Gap?
Nurse practitioners and physician assistants have been absorbing a growing share of primary care work. Federal projections estimated the primary care NP workforce would nearly double between 2013 and 2025, growing from about 57,330 to over 110,000. The PA workforce was projected to grow by 76% over the same period, from roughly 33,400 to nearly 58,800.
Research suggests NPs can manage 80 to 90 percent of the care typically provided by primary care physicians, including taking histories, ordering and interpreting tests, developing treatment plans, and delivering preventive care. Federal modeling has found that with changes to how care is delivered and fuller use of NP and PA services, the projected primary care physician shortage could be effectively offset. More strategic deployment of these providers could also help reduce regional disparities in access.
That said, expanding the NP and PA workforce addresses the symptom without fixing the underlying causes. The financial disincentives, training bottlenecks, administrative burden, and payment imbalances that drive physicians away from primary care remain largely unchanged. Until those structural problems are addressed, the shortage will continue to shape where and how Americans can access basic medical care.
