Thirty-six states and the District of Columbia currently limit entry or expansion of health care facilities through certificate-of-need (CON) programs. These programs prohibit health care providers from entering new markets or making changes to their existing capacity without first gaining the approval of state regulators. Since 1973, Tennessee has been among the states that restrict the supply of health care in this way, with 20 devices and services—ranging from acute hospital beds to magnetic resonance imaging (MRI) scanners to psychiatric services—requiring a certificate of need from the state before the device may be purchased or the service offered.
CON restrictions are in addition to the standard licensing and training requirements for medical professionals, but are neither designed nor intended to ensure public health or ensure that medical professionals have the necessary qualifications to do their jobs. Instead, CON laws are specifically designed to limit the supply of health care and are traditionally justified with the claim that they reduce and control health care costs. The theory is that by restricting market entry and expansion, states might reduce overinvestment in facilities and equipment. In addition, many states justify CON programs as a way to cross-subsidize health care for the poor. Under these “charity care” requirements providers that receive a certificate of need are typically expected to increase the amount of care they provide to the poor. These programs intend to create quid pro quo arrangements: state governments restrict competition, increasing the cost of health care for some, and in return medical providers use these contrived profits to increase the care they provide to the poor.
However, these claimed benefits have failed to materialize as intended. Recent research by Thomas Stratmann and Jacob Russ demonstrates that there is no relationship between CON programs and increased access to health care for the poor. There are, however, serious consequences for continuing to enforce CON regulations. In particular, for those in Tennessee, these programs could mean approximately 8,500 fewer hospital beds, 32 fewer hospitals offering MRI services, and 45 fewer hospitals offering computed tomography (CT) scans. For those seeking quality health care throughout Tennessee, this means less competition and fewer choices, without increased access to care for the poor.
The Rise of CON Programs
CON programs were first adopted by New York in 1964 as a way to strengthen regional health planning programs. Over the following 10 years, 23 other states adopted CON programs. Many of these programs were initiated as “Section 1122” programs, which were federally funded programs providing Medicare and Medicaid reimbursement for certain approved capital expenditures. Tennessee enacted its first CON program in 1973. The passage of the National Health Planning and Resources Development Act of 1974, which made certain federal funds contingent on the enactment of CON programs, provided a strong incentive for the remaining states to implement CON programs. In the seven years following this mandate, nearly every state without a CON program took steps to adopt certificate-of-need statutes. By 1982 every state except Louisiana had some form of a CON program.
In 1987, the federal government repealed its CON program mandate when the ineffectiveness of CON regulations as a cost-control measure became clear. Twelve states rapidly followed suit and repealed their certificate-of-need laws in the 1980s. By 2000, Indiana, North Dakota, and Pennsylvania had also repealed their CON programs. Since 2000, Wisconsin has been the only state to repeal its program.
Tennessee remains among the 36 states, along with the District of Columbia, that continue to limit entry and expansion within their respective health care markets through certificates of need. On average, states with CON programs regulate 14 different services, devices, and procedures. Tennessee’s CON program currently regulates 20 different services, devices, and procedures, which is much higher than the national average. As figure 1 shows, Tennessee’s certificate-of-need program ranks seventh most restrictive in the United States.
Do CON Programs Control Costs and Increase the Poor’s Access to Care?
Many early studies of CON programs found that these programs fail to reduce investment by hospitals. These early studies also found that the programs fail to control costs. Such findings contributed to the federal repeal of CON requirements. More recently, research into the effectiveness of remaining CON programs as a cost-control measure has been mixed. While some studies find that CON regulations may have some limited cost-control effect, others find that strict CON programs may in fact increase costs by 5 percent. The latter finding is not surprising, given that CON programs restrict competition and reduce the available supply of regulated services.
While there is little evidence to support the claim that certificates of need are an effective cost-control measure, many states continue to justify these programs using the rationale that they increase the provision of health care for the poor. To achieve this, 14 states include some requirement for charity care within their respective CON programs. This is what economists refer to as a “cross subsidy.”
The theory behind cross-subsidization through these programs is straightforward. By limiting the number of providers that can enter a particular practice, and by limiting the expansion of incumbent providers, CON regulations effectively give a limited monopoly privilege to providers that receive approval in the form of a certificate of need. Approved providers are therefore able to charge higher prices than would be possible under truly competitive conditions. As a result, it is hoped that providers will use their enhanced profits to cover the losses from providing otherwise unprofitable, uncompensated care to the poor. Those who can pay are suppposed to be charged higher prices to subsidize those who cannot.
In reality, however, this cross-subsidization is not occurring. While early studies found some evidence of cross-subsidization among hospital and nursing homes, the more recent academic literature does not show evidence of this cross-subsidy taking place. The most comprehensive empirical study to date, conducted by Thomas Stratmann and Jacob Russ, finds no relationship between certificates of need and the level of charity care.
The Lasting Effects of Tennessee’s CON Program
While certificates of need neither control costs nor increase charity care, they continue to have lasting effects on the provision of health care services both in Tennessee and in the other states that continue to enforce them. However, these effects have largely come in the form of decreased availability of services and lower hospital capacity.
In particular, Stratmann and Russ present several striking findings regarding the provision of health care in states implementing CON programs. First, CON programs are correlated with fewer hospital beds. Throughout the United States there are approximately 362 beds per 100,000 persons. However, in states such as Tennessee that regulate acute hospital beds through their CON programs, Stratmann and Russ find 131 fewer beds per 100,000 persons. In the case of Tennessee, with its population of approximately 6.5 million, this could mean there are about 8,500 fewer hospital beds throughout the state as a result of its CON program.
Moreover, several basic health care services that are used for a variety of purposes are limited because of the Tennessee’s CON program. Across the United States, an average of six hospitals per 500,000 persons offer MRI services. In states such as Tennessee that regulate the number of hospitals with MRI machines, the number of hospitals that offer MRIs is reduced by 2.5 per 500,000 persons. This could mean 32 fewer hospitals offering MRI services throughout the state. Tennessee’s CON program also affects the availability of CT services. While an average of nine hospitals per 500,000 persons offer CT scans, CON regulations are associated with a 37 percent decrease for these services. For Tennessee, this could mean about 45 fewer hospitals offering CT scans.
While CON programs were intended to limit the supply of health care services within a state, proponents claim that the limits were necessary to either control costs or increase the amount of charity care being provided. However, 40 years of evidence demonstrate that these programs do not achieve their intended outcomes, but rather decrease the supply and availability of health care services by limiting entry and competition. For policymakers in Tennessee, this situation presents an opportunity to reverse course and open the market for greater entry, more competition, and ultimately more options for those seeking care.
