Beatrice, whose name has been changed to protect her privacy, recently sat in an examination room at Brigham and Women’s Hospital, recovering from a traumatic fall that could have easily resulted in a lengthy hospitalization. While the primary reason for her visit was the physical trauma of the fall, the actual medical encounter encompassed a vast spectrum of clinical and emotional labor that often goes unmeasured in the traditional American healthcare billing machine. During the visit, I reviewed security footage of the incident captured on her smartphone to understand the mechanism of injury, performed a comprehensive physical assessment, and meticulously designed a pain management strategy tailored to avoid exacerbating her chronic gastritis. However, the scope of the visit quickly expanded: we addressed a resurgence of her generalized anxiety, titrated her thyroid hormone replacement therapy, administered a necessary vaccine, and coordinated a follow-up nursing check-in to ensure her safety at home.
This multifaceted encounter epitomizes the quintessential role of the primary care physician—a role that has historically been undervalued in a healthcare system designed to reward discrete, high-tech procedures over long-term cognitive management. For decades, the complexity of this "relationship-based" care was largely invisible to insurers. However, as of January 2024, Medicare began allowing clinicians to recognize this work through a specific line item on the doctor’s bill: the G2211 code. This code allows for an additional reimbursement of approximately $16 per visit, intended to compensate for the "inherent complexity" of providing ongoing, longitudinal care. As a health services researcher and internal medicine physician at Harvard Medical School, I have viewed this code with a mixture of professional optimism and academic skepticism. While it represents a well-meaning attempt by the Centers for Medicare & Medicaid Services (CMS) to shore up the crumbling foundation of the primary care sector, recent data suggests that the implementation of G2211 may be missing its intended mark.
To understand why a $16 billing code has become a flashpoint in health policy, one must first understand the structural inequities of the Medicare Physician Fee Schedule (PFS). The PFS is the primary mechanism through which Medicare, and by extension most private insurers, determines how much a doctor is paid for their time. For years, these rates have been influenced by the Relative Value Scale Update Committee (RUC), a group dominated by specialists. Under this framework, procedural interventions—such as cataract surgeries, colonoscopies, or skin biopsies—have been assigned significantly higher values than "cognitive" work, such as managing a patient with five co-morbidities or diagnosing a rare autoimmune disorder through careful history-taking. This "fee-for-service" model essentially treats healthcare as a series of transactions, ignoring the "invisible" work that happens between visits, such as coordinating care with specialists, answering patient messages, or reconciling medication lists to prevent adverse drug interactions.
The consequences of this payment distortion are profound and systemic. When primary care is underfunded, clinicians are forced into a "hamster wheel" of high-volume, short-duration visits to remain financially viable. This environment fuels physician burnout and discourages medical students from entering primary care, leading to a projected shortage of up to 48,000 primary care physicians by 2034, according to the Association of American Medical Colleges (AAMC). The Milbank Memorial Fund’s 2025 Health of US Primary Care Scorecard further highlights that the United States continues to underinvest in primary care compared to its international peers, spending only about 5% to 7% of total healthcare dollars on primary care, whereas other OECD nations often spend double that amount. This underinvestment correlates directly with the United States’ lagging life expectancy and higher rates of preventable chronic disease.
The G2211 code was introduced as a targeted remedy for these issues. CMS designed the code to support clinicians who serve as the "continuing focal point" for all of a patient’s healthcare needs. In its inaugural year, the code saw significant utilization, being billed 26 million times by roughly 25% of all physicians who bill Medicare. This level of adoption is remarkably high compared to previous attempts at introducing complex care codes, which often suffered from low uptake due to overly burdensome documentation requirements. However, a deeper analysis of the billing data reveals a surprising trend: the largest share of G2211 claims (43%) did not come from primary care physicians, but from specialists.
While the law prevents Medicare from restricting a billing code to a specific specialty, the intent of G2211 was to support holistic, relational care. While some specialists, such as infectious disease doctors treating patients with HIV or neurologists managing chronic Parkinson’s disease, do provide longitudinal care that mirrors primary care, many others may be using the code for more transactional encounters. Our research indicates that many specialist claims were for relatively stable conditions like mild glaucoma or acid reflux—conditions that, while requiring management, may not meet the threshold of complexity the code was intended to address. This creates a policy dilemma: in the zero-sum game of the Medicare Physician Fee Schedule, where total spending is capped by budget neutrality requirements, the widespread use of G2211 by specialists could inadvertently dilute the financial boost intended for the primary care sector.
Furthermore, the implementation of G2211 has introduced a new layer of friction into the doctor-patient relationship. For a patient, receiving a bill that includes an "add-on" fee for the "complexity" of their relationship with their doctor can feel like being "nickel-and-dimed." While the out-of-pocket cost for a Medicare beneficiary is typically small—around $3—it represents a fundamental shift in how patients perceive their care. A notable critique recently appeared in the Wall Street Journal, where a contributor lambasted the code as "blithering piffle," arguing that hospitals and doctors were using administrative jargon to justify extra charges for standard care. This highlights the "moral injury" felt by many primary care physicians: the necessity of clicking an extra box to "codify" a relationship that should be the standard of care, only to have that code cause confusion or resentment for the patient.
Despite these growing pains, CMS recently announced its intention to maintain the G2211 code, signaling a commitment to the principle of longitudinal care. However, the agency also recognizes that a per-visit add-on code is a blunt instrument for a complex problem. In January 2025, Medicare introduced the Advanced Primary Care Management (APCM) codes, which represent a more evolved approach to payment reform. Unlike G2211, which is tied to an in-person or telehealth visit, APCM codes allow for monthly per-patient payments. This "capitated" or "value-based" payment model is designed to cover the totality of care provided by a medical home, including the work of nurse practitioners, social workers, and pharmacists who may never bill for a discrete visit but are essential to a patient’s health.
The transition toward APCM and other "hybrid" payment models, which Medicare plans to expand in 2027, suggests a move away from the transactional nature of fee-for-service. The goal is to create a system where a physician like myself can spend thirty minutes counseling a patient on lifestyle modifications or coordinating with a home health agency without worrying about whether those minutes are "billable" under a specific CPT code. High-quality primary care has been consistently linked to better health outcomes, lower emergency department utilization, and increased longevity. For the U.S. healthcare system to realize these benefits, the payment structure must reflect the reality that primary care is a continuous service, not a collection of isolated events.
In the case of Beatrice, the G2211 code allowed me to be slightly better compensated for the extra time her visit required. It acknowledged that she is more than a "fall risk" or a "gastritis patient"; she is a person with a complex history who requires a trusted advisor to navigate a fragmented medical landscape. Yet, as our research suggests, a $16 add-on code is merely a bridge, not a destination. As we look toward 2027 and beyond, the success of American primary care will depend on our ability to move beyond "nickel-and-diming" the doctor-patient relationship and instead make a sustained, systemic investment in the people and processes that keep us healthy. The G2211 code was a necessary first step in acknowledging the value of the primary care relationship, but the true transformation will require a fundamental reimagining of how we value health over volume.
