Health plans with relatively narrow provider networks have generated widespread debate, mainly concerning the level of regulatory oversight necessary to ensure plans provide consumers meaningful access to care. The Affordable Care Act creates the first federal standard for network adequacy in the commercial insurance market for plans offered through the law’s insurance marketplaces. However, states continue to play a primary role in setting and enforcing network rules. This brief examines state network adequacy standards for marketplace plans in the 50 states and District of Columbia. We identify state requirements in effect at the outset of marketplace coverage, focusing on quantitative measures of network sufficiency and rules designed to ensure the delivery of accurate and timely provider directories. We then explore the extent to which those standards evolved for 2015. Though regulatory changes were limited in year one, states were most likely to act to promote network transparency and enhance oversight.
“Narrow network plans”—that is, health plans with limited networks of providers—were common on the Affordable Care Act’s (ACA’s) health insurance marketplaces in 2014. By one measure, almost half of all marketplace plan networks were “narrow” and nearly all consumers had access to buy such a plan if they chose.1 These narrow network plans are not new nor are they unique to the ACA’s marketplaces; for years, insurers have used limited networks as a way to constrain costs and regain leverage in contract negotiations with providers.2 At the same time, elements of the ACA that encourage insurers to compete on price—for example, marketplaces that allow consumers to compare plans based on premiums and increased standardization of benefits and cost-sharing—appear to have spurred many carriers to design health plans for 2014 that combined an attractive premium with a more restricted choice of providers.3
Narrow network plans may offer value to many consumers if their comparatively lower upfront costs are coupled with meaningful access to a sufficient array of providers. Flexibility to contract selectively also may allow insurers to build networks of providers who can satisfy measures of quality and efficiency, which may lead to higher-value care. But these plans also pose risks. If a network is too narrow, it may jeopardize consumers’ ability to obtain critical services or expose them to the often significant financial costs of out-of-network care. If the design is not transparent—that is, if consumers do not receive accurate and timely information about participating providers—it may be impossible for consumers to make an informed decision about whether the plan’s combination of network and price is right for them.
To help ensure that plans offered on the marketplaces serve the needs of enrollees, the ACA established a national standard for network adequacy.4 Marketplace plans must maintain “a network that is sufficient in number and types of providers” so that “all services will be accessible without unreasonable delay,” and are required to disclose their provider directories to the marketplace for online publication.5
These provisions offer consumers federal protections where previously none existed. Yet the federal framework also gives states significant latitude to determine whether an insurer has complied with the requirements, as well as the power to enforce additional, state-specific network rules if desired.6 Prior to the ACA, most states had some standards governing plan networks. Heading into 2014 and the first year of marketplace coverage, these state rules, depending on their scope, began to apply to some offerings on the marketplaces. Meanwhile a minority of states took steps to create new requirements for marketplace coverage.
This brief describes the network adequacy standards applicable to marketplace plans in each of the 50 states and the District of Columbia at the outset of marketplace coverage in 2014.7 In particular, we focus on quantitative standards that states have set to test the sufficiency of provider networks, and on requirements designed to ensure that consumers have access to updated provider directories. Then we identify the extent to which those requirements evolved in preparation for year two.
In the First Year of Coverage, About Half of States Had One or More Quantitative Standards to Measure the Adequacy of Marketplace Plan Networks
By January 2014, nearly all states had rules intended to promote the sufficiency of health plans’ provider networks. In general, these standards seek to ensure that enrollees have reasonable access to in-network providers who perform the health services covered by their insurance policy. However, the particulars of these requirements vary substantially. In many states the rules apply only to a subset of plans—for example, health maintenance organizations (HMOs)—that use a specific network design. The timing and frequency with which these standards are applied differ, as well. In many states, regulators conduct network adequacy reviews only when an insurer initially seeks licensure, upon notice of a significant change in a plan’s network, or in response to complaints. Oversight on an ongoing basis is much less common.8
Twenty-one states had qualitative standards to assess the adequacy of plans’ provider networks. For example, Maryland requires carriers to maintain a panel of in-network providers that is “sufficient in numbers and types of available providers to meet the health care needs of enrollees.”9
Kansas uses a similar formulation, requiring a “sufficient” mix of in-network providers so enrollees can access all covered services “without unreasonable delay.”10 These approaches, variations of which are common in other states, resemble key provisions of a 1996 model law developed by the National Association of Insurance Commissioners (NAIC).11
In contrast, 27 states had rules requiring at least some network-based marketplace plans to satisfy one or more quantitative measures of sufficiency (Exhibit 1). These standards took different forms (Exhibit 2). Most frequently, states specified the maximum amount of time and/or distance an enrollee must travel to access covered services. Twenty-three states had such requirements in place at the start of 2014, including New Jersey, which obligates its managed care plans to have available at least two primary care physicians within 10 miles or 30 minutes driving or public transit time of 90 percent of its enrollees.12
Eleven states impose limits on how long enrollees can be made to wait for appointments for services. Montana, for example, requires managed care plans to ensure access to urgent care within 24 hours; nonurgent care with symptoms within 10 days; immunizations within 21 days; and routine or preventive services within 45 days.13 Nearly as many—10 states—have standards prescribing minimum ratios of providers to enrollees. Nevada requires that its marketplace plans adhere to ratios for internal medicine providers (at least one for every 2,500 covered persons) and for certain specialized services (e.g., one cardiology provider for every 7,500 enrollees).14 Less common are rules requiring plans to ensure access to providers at flexible times or during extended office hours. California was one of just seven states with such requirements, obligating certain network plans to include providers that offer nonemergency services until 10 p.m. at least one day per week, or for at least four hours each Saturday.15
In 2014, 10 States Required Insurers to Update Provider Directories at Least Semiannually
Federal regulations require marketplace plans to make their provider directories available to the marketplace for online publication and to potential enrollees in hard copy upon request.16
Heading into the first year of marketplace coverage, a minority of states were enforcing rules of their own that augmented the federal standard by specifying the frequency with which insurers must update their provider lists. Nine states required network plans to provide updated directories at fixed intervals throughout the year. In addition, Arkansas mandated that insurers submit an updated directory within 14 days of any change (Exhibit 3).17
Though Few States Made Significant Changes to Network and Provider Directory Standards for 2015, More Acted to Increase Oversight
In 2014, policymakers in most states considered whether and how to adjust their regulatory approach to network adequacy. But by January 2015, few states had yet charted a substantially different course. In three states, regulators developed new quantitative requirements.18 Arkansas officials issued regulations obligating network plans offered inside and outside the marketplaces to adhere to time and distance standards beginning in 2015.19 Regulators in the California Department of Insurance filed emergency rules that adopted appointment wait time standards similar to those already applicable to plans regulated by the state’s Department of Managed Health Care.20 Meanwhile, in Washington, authorities revised the state’s framework to incorporate more detailed and concrete network standards. These additions include time and distance requirements, a specified ratio of primary care providers to plan enrollees, and maximum wait times for primary care and specialist appointments.21
A somewhat larger number of states set rules intended to increase the transparency of plan networks. Six states tightened requirements for plans to update provider directories (Exhibit 4).22 For example, as part of its broader overhaul of network standards, Washington included a requirement for plans to update their directories on a monthly basis.23 New York’s legislature imposed a still more stringent standard, mandating that online directories be made current within 15 days of the addition or termination of a provider from the network or a change in a physician’s hospital affiliation.24 Illinois and Maine passed legislation promoting timely disclosures of directory information.25 This new legal authority will make it easier for regulators in those states to develop more specific requirements in the future, should they choose.
In addition, at least six states, including Arkansas, California, Mississippi, New Hampshire, New York, and Washington, acted to bolster the ability of regulators to oversee and enforce marketplace plan standards. California, for example, enacted a bill that requires regulators to perform annual reviews of plans’ compliance with state standards and to post their findings, including any waivers or alternative standards that regulators approved, online.26 Mississippi issued regulations that require carriers to provide, for each of their managed care plans, a detailed filing describing the plan’s network and the insurer’s processes and procedures for complying with the state’s network adequacy rules. The new regulation also establishes explicitly that regulators have authority to enforce the state’s network standards in the event of a violation.27
The first year of marketplace coverage triggered widespread interest in how health plans design provider networks. This attention has reignited debate—largely dormant since the proliferation of managed care plans in the 1990s—about the degree to which those networks meet the needs of consumers and the level of regulatory oversight appropriate to ensure they do.
The ACA addresses these issues by establishing the first-ever federal standard for network adequacy in the commercial insurance market, applicable nationwide to plans available through the insurance marketplaces. The federal rules that implement this standard create a flexible regulatory framework that defines “network adequacy” qualitatively. Health plans are not required to meet more rigorous quantitative standards—a decision by officials at the U.S. Department of Health and Human Services (HHS) made partly in deference to the “historical flexibility and responsibility” enjoyed by states in this area.28 In addition, to encourage insurer participation in the marketplaces and make it more likely that consumers would have a broader choice of plans, state and federal officials gave insurers further flexibility to satisfy network standards in 2014.29
In response to feedback and ongoing public discussion about the benefits and risks of narrow networks, federal regulators sought to increase oversight for the second year of coverage. Officials are now evaluating plans that seek certification on the federally facilitated marketplaces using a “reasonable access” standard that focuses on provider practice areas that have historically raised network adequacy concerns.30 HHS also recently adopted more stringent requirements for provider directories, including an obligation for insurers to update those lists online at least once each month.31 Meanwhile, the NAIC is considering revisions to its existing network adequacy model law.32 The current version served as a template for federal network adequacy rules and HHS has indicated it will await the results of the NAIC’s work before proposing significant changes to the federal framework.33
As these developments unfolded, many state policymakers weighed whether to revisit their states’ standards. Prior to 2014, nearly all states had erected some sort of regulatory framework for network adequacy. As a practical matter, however, oversight processes were highly uneven both across and within states. In many instances, adequacy requirements applied only to certain types of network designs. Moreover, because assessing compliance with network standards can be complex and resource-intensive, fairly few states conducted regular reviews of plan networks after an insurer had been granted its state license.
In the first year of marketplace coverage, most states maintained these rules as-is or made only incremental changes. Two states, Arkansas and Washington, joined the ranks of those that use a quantitative measure to evaluate the adequacy of plan networks, bringing the total number to 29 states by January 2015. More states prioritized efforts to improve the accuracy and timeliness of provider directories—14 now require directory updates at least semiannually or within a specified interval from any change—or to bolster the authority of regulators to oversee and enforce their network rules.
The relatively deliberate pace of regulatory change at the state level in 2014 is not altogether surprising. To grapple with recent developments in network design, states must balance competing considerations: consumer (and provider) interest in broad access to in-network care on one hand, and consumer (and insurer) interest in flexible health plan designs that facilitate more affordable premiums on the other. There is evidence that some states may have been reluctant to act too aggressively or too quickly in the absence of robust market data and feedback from consumers and stakeholders about their experiences with narrow network marketplace plans.34 Others have begun to solicit stakeholders’ input with an eye toward developing new rules or oversight mechanisms in the future.35
As the process of refining regulatory approaches to narrow networks moves forward on multiple tracks—in individual states, at the NAIC, and at the federal level—it is possible that more states will pursue policies similar to those that proved popular among state officials in 2014. More may seek to enhance network transparency, so consumers can better understand the trade-offs posed by these plans, and to strengthen oversight authority, so regulators may more effectively monitor compliance with existing standards. This latter approach may also include efforts to collect and process data that illustrate how networks are working for consumers, including information on use of out-of-network services and claims appeals.36 As the marketplaces move through their second year, continued tracking and analysis of these developments will be essential to understanding how consumers are experiencing their coverage.

7 State network adequacy standards may apply broadly, to all network plans, or more narrowly, to specified network designs (e.g., health maintenance organizations (HMOs)) or plan types (e.g., marketplace plans). Our analysis focuses on state standards that apply to marketplace plans in either of two ways: 1) through state action that specifically identifies the requirements for marketplace plans; or 2) to the extent a marketplace plan uses a network design (e.g., HMO) that is regulated by the state standard. Thus, in a given state, a standard may apply to some, but not necessarily all, marketplace plans, depending on its scope.
