I. Introduction
Preventive health services consist of services — such as screenings, counseling, and immunizations — that can prevent illness or its severity, including death.Footnote 1 Clinical preventive care services, such as immunization, prevent the onset of illnesses.Footnote 2 Preventive care also can prevent potentially lethal conditions, such as high blood pressure, from worsening. Extensive research has found that preventive care can decrease the incidence of disease, facilitate earlier detection, improve health outcomes, and avert premature death.Footnote 3 The importance of preventive services to support population and community health will increase as the U.S. population continues to grow older and sicker. Indeed, a principal goal of Healthy People 2030, a national health initiative under the Department of Health and Human Services identifying science-based public health objectives, is to improve access to, and use of, preventive care.Footnote 4
Preventive services play a particularly important role in maternal and infant health, a matter of high concern in the United States.Footnote 5 Health problems in connection with pregnancy and the postpartum period have emerged as chief problems,Footnote 6 and many drivers of maternal mortality are amenable to preventive care, such as early detection and treatment of high blood pressure and gestational diabetes.Footnote 7 The value of prevention extends beyond physical health conditions; a Centers for Disease Control and Prevention (CDC) study found that 23% of pregnancy-related deaths were the result of mental health conditions, and early screening and detection before, during, or after pregnancy can help alleviate deadly outcomes.Footnote 8 Early intervention not only protects mothers, but can also avert infant mortality and lifelong disabling consequences attributable to serious conditions, such as low birthweight.Footnote 9
Preventive care largely takes place in the context of primary care.Footnote 10 However, while primary care is essential to a high-performing health care system, the United States falls well behind other nations on measures of primary care access and quality.Footnote 11 In recent years, the Biden Administration has taken steps to increase access to primary care using strategies identified by the National Academies of Science, Engineering, and Medicine.Footnote 12
Chief among those tools are community health centers (CHCs or “health centers”). Established as a small demonstration in 1965, over the course of nearly six decades CHCs have emerged as the chief strategy for anchoring comprehensive primary care in medically underserved rural and urban communities.Footnote 13 In 2022, CHCs operating across nearly 15,000 sites furnished health care to more than 30 million people, or approximately one in ten Americans.Footnote 14 Their patients are disproportionately low income (66% below 100% of the federal poverty level) and people of color (representing 59%of patients).Footnote 15 Health centers are known for the quality of their careFootnote 16 and their accessibility given their obligation to adjust charges to reflect patient income.Footnote 17 The scope of primary health care required of all CHCs under federal law, which authorizes their establishment and operation along with operational funding, is considerable.Footnote 18 Required services encompass a full range of preventive health care services like prenatal and perinatal care, cancer screening, cholesterol screening, family planning, preventive dental care, and well-child care, which includes preventive dental and vision care, immunizations, screenings for elevated blood lead levels, and screenings for communicable diseases.
Health centers rely on a combination of grants and patient fees for revenue.Footnote 19 Operational grant funding is modest; a temporary surge in COVID-19 funding elevated grant and contract support to about 34% of total operating revenue, but that figure will decline as supplemental COVID-19 funds disappear.Footnote 20 Historically, federal operating funds have reflected about 20% of total operations,Footnote 21 and when adjusted for inflation, grant funding has actually decreased over time.Footnote 22 Funding levels going forward remain unclear: they depend on a combination of discretionary appropriations as well as a Community Health Center Fund established as part of the Affordable Care Act (ACA)Footnote 23 that, despite its status as a permanent legal authority, utilizes a funding system that requires extension every few years.Footnote 24 Thus, base operational funding for health centers is not only modest, but also in a constant state of uncertainty. In 2022, 513 centers serving 11 million patients were already operating at a deficit.Footnote 25
For this reason, insurance revenue plays a major role in CHC financial viability. Insurance is vital to health centers and patients, not only from a financial standpoint for the operational income it produces, but also from a clinical standpoint because it enables access to specialized treatment for physical and mental health conditions when they are identified. Given the extreme poverty in which health center patients live, Medicaid is by far the most important source of third-party revenue; in 2022, Medicaid payments represented 42% percent of all operational financing.Footnote 26 But as a result of the ACA, private insurance has taken on growing significance: subsidized private insurance has become available to patients with incomes in excess of 138% of the federal poverty level, and 100% of the poverty level in non-ACA-expansion states.Footnote 27 Between 2010 and 2022, the percentage of health center patients reporting private insurance coverage rose from 14% to 20%.Footnote 28 Since employer coverage rates remained both low and effectively unchanged over this period — especially for low-wage earners — it is reasonable to attribute the sizable growth in coverage to the establishment of a heavily subsidized private insurance marketplace.Footnote 29
For low-income insured people, the scope of insurance coverage and point-of-care cost-sharing also take on added importance because they lack discretionary income needed to overcome insurance coverage limits. A half-century of data underscores that preventive care ranks among the most price-sensitive careFootnote 30 both because the need is invisible and the absence of a health problem gives people a false sense of security regarding the consequences of forgoing care. For this reason, the ACA preventive benefits provision is highly important for poorer people generally and health center patients in particular. While health centers are obligated to adjust their charges, patients nonetheless can face modest (but for them insurmountable) charges that cause them to avoid seeking care.Footnote 31
By guaranteeing comprehensive preventive coverage without cost-sharing for virtually all privately insured patients, and those insured through Medicaid expansion,Footnote 32 the ACA has made comprehensive preventive care accessible and affordable. For health center patients, the ACA coverage is essential because it offers complete protection against cost-sharing. Coverage provides health centers a much-needed source of revenue, thereby enabling them to allocate their modest levels of grant funding to uninsured patients and services. Despite the ACA, CHCs continue to see large numbers of uninsured patients (19%in 2022Footnote 33 with research consistently showing significantly higher rates of uninsurance in non-expansion states)Footnote 34 and many key services remain outside the scope of insurance coverage requirements, even for patients with health insurance (e.g., adult dental and vision care).Footnote 35
It is against this backdrop that Braidwood Management, Inc. v. Becerra has unfolded.Footnote 36 Braidwood involves wide-ranging constitutional challenges to the legality of the ACA guarantee of free coverage for a broad array of evidence-based preventive health care. The plaintiffs argue that Congress unconstitutionally delegated the power to establish detailed insurance coverage requirements, and that in the context of insurance mandates, the key expert bodies whose recommendations form the basis for the insurance mandates violate the Constitution’s Appointments and Vesting Clauses.Footnote 37 Separately, plaintiffs argue that the free coverage mandate related to preexposure prophylaxis (PrEP) violates their rights under the Religious Freedom Restoration Act.Footnote 38 Thus, the full range of ACA preventive benefits – child health services recommended by the Health Resources and Services Administration (HRSA) Bright Futures program (“Bright Futures”), immunizations recommended by the CDC Advisory Committee on Immunization Practice (ACIP), women’s health services recommended by HRSA’s Women’s Preventive Services Initiative (WPSI), and services recommended by the United States Preventive Services Task Force (USPSTF) – are on the line in Braidwood. Footnote 39
Should the challengers ultimately prevail on their claims now before the Fifth Circuit, it is possible that the free preventive benefit guarantee would disappear and, along with it, coverage for some or all of the preventive benefits added since the ACA’s enactment.Footnote 40 It is also possible that insurers would continue to cover some affected benefits while reinstating cost-sharing including deductibles, coinsurance, and copayments. The extent of benefits loss would be tied to the scope of plaintiffs’ victory because different legal claims affect each of the four preventive service bundles in different ways. A total victory on all claims could result in a total loss of all the benefits secured by the free preventive benefit guarantee.Footnote 41
With the loss of the coverage guarantee, some insurers might drop benefits altogether, while others might retain coverage but reimpose cost-sharing. Regardless of whether coverage is nominally retained, reimposition of cost-sharing likely would reinstate the very barriers that historically deterred use of preventive care and the preventable health consequences that would follow.
An analysis by KFF found that about 5% of privately insured people in the United States used a relevant preventive service or drug in 2019,Footnote 42 making the access effects of Braidwood potentially considerable. In our earlier research focusing on Braidwood’s implications for women’s health, we found that if post-2010 preventive benefits were to fall away, coverage for 122 preventive services and ninety preventive services relevant to maternal and infant health would be lost in their entirety.Footnote 43 Other research has shown that 4.6 million women could lose access to the free contraceptive services they used in 2022 and over 12,000 infants could lose access to the free newborn screening panel.Footnote 44
How might these losses affect CHCs and their patients? The federal requirement that CHCs serve all, irrespective of ability to pay, and provide these services for free when patients cannot otherwise afford them, suggests that CHCs may face additional financial pressure and operating difficulties if the plaintiffs’ arguments prevail.Footnote 45 The higher the share of services furnished by CHCs that fall into one or more of the preventive services categories, the greater the access and financial risks raised by Braidwood, with spillover effects on overall CHC operating revenues and patient care capacity. The implications might be greater for CHCs that have expanded preventive care staffing and service sites to accommodate increased demand, particularly from older working-age patients with rising health needs, children, and women of childbearing age for whom health centers are a major source of both pregnancy-related and preventive reproductive health care.Footnote 46
II. Methods
This paper focuses on the free ACA preventive services that health centers provide, with particular emphasis on women, infants, and children, whose use of preventive care is a major priority both for coverage reforms and CHCs. Together, children under the age of eighteen and women aged eighteen to forty-four represent 51%of all health center patients.Footnote 47 This analysis utilizes the publicly available preventive services recommendations from the USPSTF, ACIP, WPSI, and Bright Futures, as well as data from the annual Uniform Data System (UDS) to which all CHCs report annually.
We first compiled all the recommendations subject to the ACA free preventive service requirement through the end of 2023, cataloguing any changes that occurred to each recommendation after the enactment of the ACA, comparing recommendations that overlapped between recommending bodies, and flagging recommendations specific to maternal, infant, or child health. Because the challengers are pursuing the overturn of coverage for all preventive service bundles in the ACA, we examined all bundles but tracked the recommending body source, which allows for more flexible analysis if only a subset of the recommending bodies’ recommendations are found to be unconstitutional. To verify our analysis, we ensured at least two team members examined each recommendation. We released these findings on our website in 2023.Footnote 48 We then mapped the most recent 2022 UDS measures to these recommendations to quantify the number of patients using relevant services and the potential number of CHC patients who could be impacted under a Braidwood ruling for the plaintiffs. Utilizing the UDS, we matched the preventive procedures found in the previous analysis with quality measures when available, given that these measures tended to be more directly comparable to the procedures. In the absence of relevant quality measures, we looked at other recorded services. In the absence of service information, we looked for relevant diagnoses that mapped to screenings for those conditions.
While only a subset of CHC patients are covered under insurance that could be subject to change under a ruling in favor of plaintiffs, this analysis provides an important first upper bound so that researchers, health centers, government officials, patients, and advocates can begin to understand the practical implications of such a decision. Furthermore, because marketplace coverage plays an outsize role in non-expansion states (owing to the lower subsidy eligibility threshold), losses could be especially significant for CHCs already facing greater revenue challenges because so many of their patients fall into the Medicaid coverage gap, leaving them with higher uninsured rates.Footnote 49 health centers in non-expansion states experience uninsured rates between seventeen percentage points higher than those located in states adopting the ACA expansion.Footnote 50
Preparing these estimates is challenging given the uncertainty in the publicly funded insurance markets. This is particularly true over the 2023–2024 period because of the process of “unwinding” Medicaid’s continuous coverage guarantee, which spanned the COVID-19 public health emergency pandemic period and is projected to result in considerable losses in coverage, including ACA expansion coverage.Footnote 51 An unknown number of those undergoing unwinding may move to marketplace coverage, and early enrollment estimates suggest that to some degree, this lateral movement may be happening for people whose ACA coverage losses are attributable to slightly higher income. How well this large-scale cross-market transition will occur is unclear. Regardless, this coverage disruption underscores the difficulties confronting CHCs as their grant funding declines and the proportion of insured patients also declines. Further revenue losses from Braidwood would only add to the problem.
Other challenges that arise in conducting a Braidwood impact estimate for CHC practice have to do with limits of the UDS. As valuable as the reporting system is, it does not distinguish between types of Medicaid coverage (e.g., expansion versus traditional eligibility categories). It is not possible to know, furthermore, what percentage of the Medicaid health center patient population losing coverage might eventually and successfully make their way to subsidized marketplace coverage. Additionally, the UDS does not provide detailed information as to the insurance status of patients for each relevant service or diagnosis. Thus, we cannot assume that the percentage of patients with a specific insurance type is consistent across each service or diagnosis, particularly for pregnant people, which is a Medicaid eligibility population category.Footnote 52
III. Results
As shown in Table 1 in Supplementary material, we identified 193 unique procedures at stake in Braidwood. Footnote 53 Two-thirds (125) of these procedures pertain to maternal and infant health, while nearly 30% (fifty-five) pertain to children and adolescents. If the Supreme Court ultimately overturned the preventive benefit guarantee across all four preventive service bundles (i.e., children’s health, women’s health, immunizations, and USPSTF recommendations), then only 25% (forty-eight) of procedures would remain fully covered without cost-sharing. Since ACA enactment, 122 entirely new recommendations have come online, including lung cancer screening, statin use for prevention of cardiovascular disease, and type 2 diabetes screening. Another thirteen procedures would remain intact but only for certain populations. For example, adolescents would no longer qualify for free alcohol use screening. Finally, ten procedures would lose changes designed to improve effectiveness as science has advanced; it is not clear that expert advisory committees would continue to recommend them under those circumstances.
Of the 125 procedures that pertain to maternal and infant health, ninety would be completely removed, including the Recommended Uniform Screening Panel for newborns and screenings for gestational diabetes, depression, and intimate partner violence for mothers. Another five procedures would only remain in place for a subset of currently recommended populations and one procedure would lose a substantial change. Of the fifty-five procedures that pertain only to child and adolescent health, twenty-four would be entirely removed, including screenings for anxiety and hepatitis C as well as provision of fluoride varnish. Another five procedures impacting children and adolescents would only remain in place for a subset of currently recommended populations and two would lose a substantial change. Among these losses, adolescents would no longer qualify for a free meningococcal vaccine.
When comparing the UDS to the 193 unique preventive procedures, we found nine quality measures collected annually that map to the recommendations, including a significant overlap in ages of populations examined; six other services that aligned with the unique preventive procedures; and seven diagnoses that aligned with a condition for which a screening is within the 193 procedures.Footnote 54 The quality measures captured were: (1) tobacco cessation intervention for adults; (2) depression screening for people aged twelve and over; (3) BMI screening with a follow-up plan as appropriate for people aged eighteen and over; (4) HIV screening for people aged fifteen to sixty-five; (5) cervical cancer screening for women aged twenty-three to sixty-four (twenty-one to sixty-five in the USPSTF recommendation); (6) statin use for patients at high risk of cardiovascular events (ages forty to seventy-five in the USPSTF recommendation); (7) colorectal cancer screening for people aged fifty to seventy-four (fifty to seventy-five in the USPSTF recommendation); (8) breast cancer screening for women aged fifty-one to seventy-three (fifty to seventy-four in the USPSTF recommendation); and (9) children aged two who received age-appropriate vaccines by their second birthday. Quality measures are of particular importance because they are a means of accountability to ensure that providers are performing services as they should.Footnote 55 These current values are important for two reasons: (1) we need to know current values to understand the volume of patients using these services who may experience changes to their coverage; and (2) CHCs may be unable to perform as well on these measures due to changes stemming from the Braidwood case outside of their control. Six of these quality measures are associated with recommendations specific to women, infants, and children, though tobacco cessation interventions, depression screenings, and HIV screenings also apply to recommendations specifying more general populations.
Use of services recommended for women, infants, and children was common. Nationally, we found that slightly over 11 million health center patients were screened for tobacco use and received counseling if appropriate — about 36% of all health center patients nationally. Tobacco cessation counseling is a USPSTF-recommended service explicitly for both pregnant and non-pregnant adults. Nearly 11 million people were screened for depression as well, a service recommended under USPSTF and Bright Futures for adults, including pregnant and postpartum women, as well as children and adolescents. Roughly 7 million patients received an HIV screening (approximately 23% of all health center patients nationally), a recommended service under USPSTF and WPSI. About 4 million women received cervical cancer screenings, and nearly 1.7 million received breast cancer screenings, services recommended under USPSTF and WPSI. Roughly 1.6 million women received contraception management, a recommended service in the WPSI service bundle, and 1.1 million patients received a hepatitis B test, a service recommended under USPSTF and Bright Futures for multiple populations including pregnant women. Approximately 126,000 patients aged two received age-appropriate vaccines by their second birthday, or approximately 33% of all patients turning two, and roughly 540,000 children aged nine to seventy-two months received a lead test screening.
We found substantial variation by state for the preventive procedure recommendations contained in the UDS.Footnote 56 The occurrence of tobacco screening ranged from 20% of CHC patients in Wisconsin to 51% of patients in New Hampshire. Similarly, depression screening ranged from 15% in Wisconsin to 52% in Nevada. The range for HIV screenings is particularly stark: 7% in Wyoming and 42% in the District of Columbia.
IV. Discussion
This analysis documents the considerable exposure faced by CHCs and their patients should the Braidwood plaintiffs succeed. Female patients subject to the ACA preventive service provision constitute a population particularly vulnerable to the withdrawal of preventive coverage, as suggested by the finding that cervical cancer screenings, breast cancer screenings, and contraception management are three common services that centers provide. Indeed, American women generally appear to use these preventive services frequently. In 2022, 72% of all women aged forty and up had received a mammogram in the past two years, and 73% of women aged eighteen to sixty-four had received a pap smear in the past three years.Footnote 57 In 2020, about three-quarters of all women reported receiving a well-woman visit or general check-up in the past two years; these frequently include mammograms, pap smears, and contraceptive counseling.Footnote 58 Women living in a household earning below 200% of the federal poverty level, which is the majority of female CHC patients, are particularly likely to postpone preventive services because of cost.Footnote 59
The evidence shows that a significant portion of health center patients receive thee preventive services (or should receive them based on diagnoses) at stake in the Braidwood case. Health center data limitations do not allow us to determine the percentage of patients who receive any of the 193 procedures at stake or understand how many may experience some change to their ability to pay for the services they need. However, a recent KFF analysis suggests that 60% of individuals who are privately insured receive at least one preventive service annually, and it seems likely that owing to the preventive orientation of health centers, their patients receive preventive service at a rate meeting or exceeding this value.Footnote 60
It is important to note that some health centers and their patients are more likely to be disproportionately affected by the effects of the Braidwood case. The state-level analyses provide some insight into these differences. For example, if the ruling regarding PrEP is upheld, health centers in Washington, DC would likely experience greater impact than centers in North Dakota because a higher percentage of DC patients receive PrEP management. When focusing on depression screenings, it appears that Wisconsin would likely experience less impact than New Hampshire.
An additional complication in understanding the magnitude of effects is that the percentage of patients who have insurance subject to the ACA preventive service provision differs by state. For example, while California has a relatively low percentage of health center patients who have private insurance (9%), and are therefore likely subject to the ACA provision, it has a relatively high percentage of health center patients who have Medicaid (67%).Footnote 61 We do not know what percentage of these Medicaid patients are in the expansion population, nor do we know if California would continue to offer full preventive coverage under its Medicaid plan, although continued coverage is likely. Other states, however, might not make the same choice. In contrast, 38% of Wyoming’s health center patients rely on private insurance and only 21% use Medicaid.Footnote 62 Because Wyoming has not expanded Medicaid, the state’s entire Medicaid enrollee population is not subject to the Braidwood ruling, making determining the potential effects of the Braidwood case somewhat more straightforward. Nonetheless, across all states, an analysis of which states and health centers tend to see more patients utilizing preventive services provides suggestive evidence as to where there may be issues.
We also lack information as to the cost of the preventive services at stake and health centers’ current reimbursement rates. However, this figure could be determined in future research. While we can find the base payment rate that Medicare must pay CHCs ($180.16 in 2022),Footnote 63 we cannot estimate the shortfall that would occur if coverage were eliminated without more detailed information. With the shortfall figure, we could begin to quantify the trade-offs that health centers may need to make. When faced with budget deficits in the past, health centers have contemplated cutting hours or services, closing sites, and layoffs.Footnote 64 For patients, these decisions mean less access to care that spills over to all patients, not just those with insurance subject to ACA preventive service provisions. Less access to care can translate to poorer health as conditions go untreated or undetected. Additionally, as patients face confusion as to whether they must pay for services, they may be less likely to seek care, particularly preventive care that does not treat an immediate acute condition.
V. Conclusion
Preventive services are a core part of CHC services by mission, legal mandate, and practice. A Braidwood ruling that eliminates coverage and changes the availability of free preventive services would have substantial effects on centers and their patients, upending care in many communities. At a time when CHCs are already experiencing a shift in patient coverage due to the Medicaid unwinding,Footnote 65 grant funding is uncertain and stagnant,Footnote 66 CHCs are in involved in the delivery of one in six low-income births,Footnote 67 and there is increased concern about pregnancy complications in a world in which the Supreme Court overturned constitutional protection for abortion,Footnote 68 the ability for health centers to provide relevant preventive screening services and receive payment for such services is essential.
