Physician Barriers to Chronic Complex Illness Care in the U.S.

Introduction

Chronic complex illnesses – such as Postural Orthostatic Tachycardia Syndrome (POTS) – often require lengthy, comprehensive medical visits and ongoing management. However, the U.S. insurance-based reimbursement system is largely designed around short, acute-care visits and procedures. This misalignment creates significant barriers to care for patients with complex chronic conditions. Physicians face financial disincentives when providing the 45–60 minute visits needed for thorough evaluation and management of such illnesses, leading many to limit or avoid these patient populations. Additionally, low reimbursement in cognitive specialties (those focusing on complex chronic care rather than high-paying procedures) discourages physicians from pursuing specialized training (e.g. in autonomic disorders like POTS), contributing to workforce shortages. Below, we examine evidence from peer-reviewed studies, policy analyses, and expert commentary – including insights from Dr. Robert Pearl’s Uncaring – on how reimbursement structures and medical culture impede chronic complex care.

Short Visits vs. Long Visits: Misaligned Reimbursement Models

Most U.S. physicians are paid under fee-for-service models that reward volume of visits and procedures over time-intensive care. Evaluation & Management (E/M) office visit codes illustrate this imbalance. For example, Medicare in 2025 reimburses a typical 15-minute office visit (CPT 99213) at around $87, whereas an extensive 45-60 minute visit for a complex patient (CPT 99215) pays roughly $172 . Three shorter visits (3 × $87 = $261) over 45 minutes actually yield more revenue than one prolonged visit, even though the latter is necessary for complex cases.  As a result, spending an hour with one complicated patient is financially negative to seeing multiple simpler cases in that time.  If the average primary care practice overhead is currently $275-325/hour prior to covering salary cost, then it becomes prohibitive without another revenue source to offset it.     

Research confirms that “amounts paid for office visits are often not large enough to allow a physician to spend the time necessary to accurately diagnose complex symptoms and … develop a treatment plan” for chronic conditions . In other words, current reimbursement rates make prolonged 45–60 minute visits economically unsustainable in a typical practice. A 2023 analysis by Harold D. Miller notes that inadequate payment per visit time is a core problem with chronic care under fee-for-service models . Physicians often feel pressure to shorten visits and increase patient throughput to maintain practice revenue, which undermines care quality for complex illnesses.

Not only is face-to-face time underpaid, but many essential services for chronic disease management are unreimbursed or poorly reimbursed. Coordination tasks – such as extensive care planning, patient education, between-visit phone consultations, and multidisciplinary management – often have no fee or fall outside standard billing codes . This further discourages clinicians from offering comprehensive chronic care, since doing so either cuts into their unpaid time or requires billing additional visits. Newer Medicare programs (e.g. chronic care management codes) have attempted to pay for some non-visit care, but uptake has been slow and payment remains modest. In summary, the prevalent fee-for-service structure “undervalues comprehensive care” while richly rewarding procedures and short problem-focused visits. This misalignment leaves complex chronic patients without the time and attention their conditions demand.

Financial Disincentives and Physician Behavior

Given these payment dynamics, it is perhaps unsurprising that many physicians avoid or limit involvement with high-complexity chronic patients. Simply put, caring for such patients can be financially penalizing. If a doctor schedules a one-hour appointment to manage a complicated condition, they forego the opportunity to see several other patients in that hour. As one policy report bluntly stated, “the specialty practice is penalized financially if it helps [complex] patients avoid exacerbations or slow progression” of disease . Under fee-for-service, a specialist who stabilizes a chronic illness (reducing emergency visits or procedures) actually loses future billable opportunities, creating a perverse disincentive to invest time upfront in effective management .

Several experts have raised concerns that inadequate reimbursement for complexity will lead providers to “avoid complex patients” altogether . For example, in response to a proposed Medicare payment change that would flatten E/M visit rates, specialty physician groups warned that if all office visits are paid the same, specialists would have “no incentive to spend extra time on complex patients” and may limit accepting those cases . A neurologist commenting on the policy noted that without proper adjustments, “specialty providers may tend to avoid complex patients due to lower reimbursement” . This phenomenon, often called “cherry-picking” or patient selection, can reduce access for those who need care the most. Providers in capitation or value-based contracts similarly might shun the sickest patients unless risk adjustments account for their higher care needs .

Empirical data on physician behavior supports these warnings. In the primary care arena, studies have long shown that physicians lack enough time to address all chronic conditions for a typical patient panel – an estimated 26.7 hours per day would be needed to fully meet preventive and chronic care guidelines for an average primary care panel, far above available time . Under such strain, doctors naturally prioritize issues that can be handled quickly or those tied to better reimbursement. One consequence is the well-documented gap in quality for chronic illness management: for instance, hypertension control rates hover around 55–60%, meaning many patients’ blood pressure is not at goal . Dr. Robert Pearl argues this shortfall is partially cultural (physicians historically prize dramatic cures over “mundane” chronic management) and partially systemic – doctors are not rewarded for meticulous chronic care, and thus may not invest the extra effort consistently . In short, the current payment structure tends to discourage physicians from devoting time to complex chronic cases, inadvertently incentivizing them to sidestep the sickest, most time-intensive patients.

Low ROI Specialties: Training Positions Go Unfilled

One major downstream effect of these financial disincentives is the impact on specialty choice and workforce supply. Medical specialties that manage chronic, complex illnesses without performing lucrative procedures often offer lower salaries. New physicians, burdened with student debt and years of training, may be reluctant to enter fields with relatively poor return on investment. This has led to shortages in fields like geriatrics, infectious disease, endocrinology, and likely autonomic disorders. In fact, non-procedural specialties have some of the highest rates of unfilled training positions in the U.S. each year.

For example, in the 2023 fellowship Match, nearly half of infectious disease (ID) fellowship programs went unfilled. Only 56% of ID programs (74% of available ID fellowship slots) filled with an applicant, despite an increasing number of training programs . The Infectious Diseases Society of America noted this persistent shortage and explicitly cited “low compensation” as a major “roadblock to recruitment” . Early-career doctors perceive (accurately) that ID specialists earn substantially less than other internal medicine subspecialists, despite the field’s critical importance for public health. The median ID physician salary (~$250–300k) trails procedurally oriented fields like cardiology by a wide margin , which dampens interest in ID fellowships. A similar trend is seen in geriatrics: year after year, more than one-third of geriatric medicine fellowship slots go unfilled . Geriatricians manage complex elderly patients with multiple chronic conditions – work that is cognitively demanding but comparatively low-paid. As a result, geriatrics is “underfunded and undervalued,” and medical students cite lower compensation and lack of exposure as key deterrents to entering the field . According to a 2025 report, primary care physicians (including geriatricians) earn about 20% less than other specialists on average, due to “outdated payment systems,” and the rate of new doctors going into primary care is at a decade low . This reflects how payment structures drive career choices.

Although data specifically on autonomic disorders (like POTS) as a subspecialty are limited, it falls into the same category of a cognitive specialty with low volume and few procedures. Autonomic neurology or cardiology programs are typically one-year fellowships with a focus on chronic conditions (POTS, dysautonomias, syncope, etc.). These fellowships are often non-ACGME or have limited slots, and they likely face challenges filling positions. There is evidence of a dearth of clinicians familiar with POTS; a recent study found that even after diagnosis, 67% of U.S. POTS patients had at least one doctor tell them they had “never heard of POTS,” indicating a scarcity of knowledgeable specialists . (In Canada, where incentives differ, the figure was an alarming 78% .) The same study noted “barriers to care” in both countries and longer diagnostic delays where specialist access was poorer . This suggests that few physicians pursue expertise in autonomic disorders. One likely reason is financial: an autonomic disorders practice involves long consultations, detailed testing (e.g. tilt-table tests, autonomic reflex screens), and extensive follow-up – services that are not highly reimbursed relative to the time and resources required. Unlike cardiologists who do catheterizations or electrophysiology procedures, a POTS specialist’s “productivity” in RVUs comes mostly from office visits and interpretations, which yield lower income. Thus, the return on investment (ROI) for spending extra years in training to become a POTS specialist is relatively low. The situation mirrors what is seen in geriatrics and ID: as one article noted, “lower compensation…[is] a barrier to growing the [geriatrics] workforce” . Autonomic medicine, being similarly undercompensated and less “glamorous” in the medical hierarchy, almost certainly struggles to attract trainees, leaving many fellowship slots unfilled and patients with limited access to care.

Quantifying the Cost of Long Visits

It is useful to quantify how reimbursement policies translate into lost income when treating chronic complex illness. Take the example of a busy clinic deciding how to allocate an hour of physician time:

• Seeing Multiple Patients: In one hour, a physician could see 3–4 routine patients (e.g. 15-20 minutes each). If each visit is a moderate complexity follow-up (billing code 99213 or 99214), the total reimbursement might be on the order of $300–$350 for that hour. Many primary care doctors and specialists structure their schedules this way to cover overhead and meet revenue targets. Currently average overhead for primary care private practice sits at $275-325/hr.  (One can see why the alarming trend of private practice disappearing, while most physicians are now employed by large hospital systems, in which the same care delivered is reimbursed at a much higher rate). 

• Seeing One Complex Patient: Alternatively, that hour could be given to a single complex patient with a chronic illness requiring an in-depth evaluation, history, care coordination, and patient counseling. Even if the physician bills the highest level visit (99215) plus perhaps a prolonged service add-on, the reimbursement is likely around $170–$200 for the entire hour . In fee-for-service terms, the opportunity cost of that long visit is a roughly 50% reduction in revenue compared to the multiple shorter visits.
  
  

Over a full clinic day, the income gap compounds. Physicians who routinely accommodate complex 60-minute visits will generate far fewer billable encounters. Unless they work under a different payment model (e.g. salary, capitation with risk adjustment, or a concierge retainer practice), they may find their practice financially unsustainable. Indeed, Medicare’s own fee schedule historically discouraged prolonged visits. Before 2021 coding changes, physicians often had to justify longer visits with extensive documentation for relatively little incremental pay. The system essentially pushes doctors toward “volume over value” – i.e., more visits rather than longer, deeper visits – when it comes to chronic care management . This financial calculus also explains why many specialists double-book appointments or have support staff perform parts of chronic care (nurse practitioners managing diabetes, etc.): they are trying to bridge the gap between what good care requires and what insurance pays for.

It is worth noting that some newer payment initiatives attempt to address this. “Chronic Care Management” (CCM) codes (like Medicare’s CPT 99490) pay a small monthly fee for care coordination of complex patients, and some private insurers or ACOs provide bonuses for high-risk care management. Yet, these payments (often on the order of ~$40–$80 per month per patient for 20+ minutes of non-face time) are relatively low , and many practices report that the administrative burden of billing CCM outweighs the benefit . As of 2020, fewer than expected clinicians were using CCM codes, citing “insufficient reimbursement” as a top barrier . The quantitative reality remains: a physician who devotes extra time to a complex chronic illness case often loses income compared to peers who focus on quick visits or procedures.

Cultural and Systemic Barriers 

Insights from “Uncaring” by Dr. Robert Pearl

Beyond pure economics, Dr. Robert Pearl’s book “Uncaring: How the Culture of Medicine Kills Doctors and Patients” highlights how medical culture and systemic incentives together create barriers in chronic care. Dr. Pearl, a former CEO of a large physician group, argues that physician culture has historically rewarded heroics and technical prowess over the painstaking work of managing chronic disease. Key insights from his commentary include:

• “20th Century vs 21st Century” Medicine: In the past, physicians had fewer tools and less understanding of chronic disease, so medical culture placed high value on clinical intuition, diagnostic acumen, and dramatic lifesaving interventions . In the 21st century, however, many of the greatest needs in healthcare involve managing chronic “lifestyle” diseases (diabetes, heart disease, obesity, etc.) through evidence-based protocols and preventive measures. Pearl notes that following established checklists and guidelines for chronic disease management can save far more lives today than spur-of-the-moment diagnostic genius . Yet, physicians often still derive their professional esteem from the old model. As he puts it, “we are living in the 21st century with a 20th century physician culture” that hasn’t fully embraced the importance of routine chronic care .
  
  
• Lack of Status and Satisfaction in Chronic Care: Treating chronic conditions by methodically adjusting medications, counseling on lifestyle, and preventing complications is vitally important but not “glamorous.” Pearl observes that doctors do not gain much status among peers by keeping a diabetic patient’s A1c controlled or a heart failure patient out of the hospital – whereas performing a complex surgery or rescuing someone in a crisis is celebrated . This cultural bias can lead to frustration and burnout. He gives an example of a urologist who originally derived great pride from doing an advanced procedure (prostatectomy) but grew dissatisfied when evidence-based guidelines reduced the need for that surgery, leaving mostly routine medical management. Even though the urologist’s pay and workload remained high, the loss of that “marquee” intervention led to burnout purely from a status perspective . Likewise, an emergency physician in his organization fell into burnout and substance misuse, citing boredom and monotony – “every day it’s the same routine stuff…no challenge” – despite doing necessary chronic care and acute minor care on each shift . These anecdotes illustrate how a culture fixated on excitement and innovation may devalue the day-to-day management of chronic illness.
  
  
• Systemic Pressures and the “Perverse” Fee-For-Service Incentive: Cultural attitudes are reinforced by the payment system. Pearl is blunt in calling fee-for-service “outdated and perverse,” linking it to both physician burnout and poor chronic outcomes . Because FFS only rewards doing more, doctors feel compelled to see more patients, order more tests, and “spend less time with each, [and] skip over the health aspects that aren’t well-compensated” . For chronic illness, those “uncompensated” aspects often include lifestyle counseling, patient education, and coordination with other providers – precisely the interventions that could prevent complications. This creates a vicious cycle: doctors rush through visits, patients with complex conditions feel unheard and unmanaged, conditions worsen, and doctors then face crises that are still reimbursed sub-optimally (e.g. long hospital discussions, end-of-life care for preventable complications). Pearl suggests that physicians’ inability to provide the care they know patients need (due to time and billing constraints) is a hidden driver of burnout and a form of “moral injury” . Doctors genuinely care about their patients, but the system’s demands force them into providing fragmented or superficial care, which conflicts with their professional values.
  
  
• “Systemic vs Cultural” – Both Need Change: Dr. Pearl emphasizes that poor outcomes in chronic disease (e.g. people “dying unnecessarily from chronic disease”) have both systemic causes and cultural causes . Systemic factors include insurance rules, lack of care integration, and patients’ socioeconomic barriers. Cultural factors include physicians’ mindsets and training. For instance, Pearl notes that when only ~55% of hypertensive patients have their blood pressure controlled, physicians don’t typically blame themselves or the culture – they may cite patient noncompliance or system issues . However, he challenges the profession to also turn inward: the culture of medicine tends to “repress and deny” its own shortcomings in managing chronic illness . Rather than treating suboptimal chronic care as a moral failing, doctors often normalize it, which stalls improvement. Pearl calls for a culture that embraces accountability for chronic care outcomes and for payment reforms that reward keeping patients healthy, not just treating them when they’re sick .
  
  

In summary, Uncaring highlights that fixing chronic care barriers isn’t only about paying doctors more – it’s also about reshaping what physicians value and how they were socialized. The current culture and payment structure arose in an era focused on acute illness; they are ill-suited for today’s chronic disease burdens. Dr. Pearl advocates for aligning financial incentives with preventive, patient-centered care and fostering a culture that finds professional fulfillment in improving chronic health outcomes, not just acute interventions .

Conclusion

Chronic complex illnesses like POTS exemplify the cracks in the U.S. healthcare reimbursement system. Patients with these conditions need doctors who can devote time and thoughtful planning to their care, but the fee-for-service model makes such care financially difficult. Peer-reviewed studies and policy analyses show that current reimbursement structures fail to support prolonged visits and comprehensive services, effectively discouraging physicians from taking on complex chronic cases . The result is fewer providers willing to treat these patients and fewer trainees entering fields that specialize in chronic care, due in large part to low ROI and income potential . Quantitatively, the system rewards brevity over thoroughness, as seen in E/M payments that prefer multiple short visits to one long visit . Culturally, medicine has been slow to elevate the importance of chronic care management to the same level as acute care heroics, though that is gradually changing.

To dismantle these barriers, experts recommend payment reforms and cultural shifts: for instance, creating “patient-centered payment” models with dedicated fees for diagnosis, care planning, and care coordination in chronic disease . Such models would pay for the “time and resources required to determine an accurate diagnosis” and manage a chronic condition, rather than paying per visit regardless of complexity . There are calls for higher compensation for cognitive care and longer visits, so that physicians are not penalized for spending time with complex patients . Additionally, adjustments in value-based programs to account for patient complexity would remove the incentive to avoid the sickest patients . On the cultural side, leaders like Dr. Pearl urge a redefinition of what is valorized in medicine – placing chronic care outcomes and prevention on par with procedural success. If residency programs and health systems start prioritizing and rewarding chronic illness management (through training, praise, and payment), more physicians might feel both intrinsically and extrinsically motivated to serve this population.

In conclusion, the barriers to chronic complex care in the U.S. are multifaceted but not insurmountable. Aligning reimbursement with the realities of chronic illness – by adequately funding longer visits and care coordination – is a crucial step. Equally important is nurturing a medical culture that finds achievement in helping patients live better with chronic disease, not just in dramatic cures. As the prevalence and cost of chronic conditions continue to rise, addressing these reimbursement and cultural issues is vital to improve access and quality of care for patients with complex illnesses. The research and expert consensus make one thing clear: a healthcare system that truly values chronic care will pay for the time it takes to do it well, and will celebrate the doctors who dedicate themselves to it .

KEY DEFINITIONS***

Chronic Complex Illness – refers to a group of medical conditions that are long-lasting (typically persisting for more than six months) and involve multiple body systems, leading to a complex array of symptoms and health challenges. These illnesses often require comprehensive and coordinated care due to their multifaceted nature. Key characteristics of chronic complex illnesses include:

•  Multisystem Involvement: These conditions affect more than one organ system, leading to a wide range of symptoms that can be difficult to manage and diagnose.  Often involving disorders of the autonomic nervous system. 
• Persistent Symptoms: Symptoms are ongoing and can fluctuate in severity, often impacting the individual’s quality of life and daily functioning.
• Complex Management Needs: Due to the involvement of multiple systems, treatment often requires a multidisciplinary approach, including various healthcare professionals such as physicians, specialists, physical therapists, and mental health providers. Requires key coordination and continuity of care by a primary care provider. 
• Potential for Comorbidities: Individuals with chronic complex illnesses often have other coexisting conditions, which can complicate diagnosis and treatment.

Chronic complex illnesses almost always present with symptoms of dysautonomia.  In addition to the examples of post viral Illness (including Long COVID),  Postural Tachycardia Syndrome (POTS), Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) noted above, other common examples include Post Concussion Syndrome, Fibromyalgia and autoimmune-related disorders like Lupus and multiple sclerosis. Some are genetically inherited, such as Ehlers-Danlos Syndrome. Many of these conditions overlap and are not mutually exclusive. Managing these illnesses typically involves a combination of medication, lifestyle modifications, psychological support, and sometimes alternative therapies. Where cures are effectively absent, the goal of treatment is chiefly to manage symptoms, improve quality of life, and maintain the highest level of function possible over the long term. 

Autonomic Disorders – is a neurology subspecialty accredited by the United Council of Neurologic Subspecialties (UCNS), dedicated to the care of complex and often chronic medical conditions involving the Autonomic Nervous System (ANS). This field is also known as Autonomic Medicine. Although it is a neurology subspecialty, it is inclusive of all specialties, including board-certified practitioners in primary care, internal medicine, pediatrics, cardiology, gastroenterology, urology, and obstetrics/gynecology, among others. Dysautonomia knows no boundaries, as all these disciplines encounter and treat problems involving dysfunction of the autonomic nervous system daily.  Certified Autonomic Disorders Specialists care for a variety of conditions under the umbrella of dysautonomia, representing some of the most severe chronic complex illnesses.

Some of the disorders managed include:

1. 1. Postural Orthostatic Tachycardia Syndrome (POTS) and Orthostatic Intolerance (OI)
   2. Neurocardiogenic Syncope (also known as Vasovagal Syncope)
   3. Multiple System Atrophy (MSA)
   4. Pure Autonomic Failure (PAF)

• Parkinsons include lewy body dementia type. 

1. 1. Familial Dysautonomia (Riley-Day Syndrome)
   2. Orthostatic Hypotension
   3. Baroreflex Failure
   4. Diabetic Autonomic Neuropathy
   5. Autoimmune Autonomic Ganglionopathy

• Autoimmune related complications of GAD-65, Sjogrens, Lupus, Rheumatoid Arthritis, Scleroderma to name several. 

• Post Viral Syndromes including LC-POTS, Neuropathic POTS, ME/CFS, resulting often in loss of cerebral blood flow.  

• Small Fiber Neuropathy

• Amyloidosis 

1. 1. Paraneoplastic Autonomic Neuropathy
   2. Hereditary Sensory and Autonomic Neuropathies (HSAN)
   3. Ehlers-Danlos Syndrome (EDS)-related Dysautonomia, “POTS Plus”

• Chronic migraines

These specialists may also manage autonomic dysfunction related to other conditions not listed.  Treatment and management strategies are tailored to each individual patient, depending on the specific disorder and its severity.

Autonomic Medicine – Specialized field of medicine focused on the study, diagnosis, and treatment of disorders related to the autonomic nervous system (ANS).  See Autonomic Disorders.

Autonomic Nervous System (ANS) – The ANS is responsible for regulating involuntary bodily functions, such as heart rate, blood pressure, digestion, and temperature control.  The Autonomic Nervous System (ANS) is the border between the brain and the body.  

Dysautonomia – Refers to a group of disorders in which the autonomic nervous system (ANS) does not function properly. It is not a diagnosis, but an umbrella term for a wide range of Autonomic Disorders (AD) that often result in symptoms of dizziness, fainting, unstable blood pressure, abnormal heart rates, digestive issues, and intolerance to exercise. The severity and specific symptoms can vary greatly depending on the underlying cause and the particular type of dysautonomia. Some common forms include Postural Orthostatic Tachycardia Syndrome (POTS), ME/CFS, and Multiple System Atrophy – representing some of the most chronic complex illnesses encountered by physicians.
