Certificate-of-Need Laws: How They Affect Healthcare Access, Quality, and Cost

What years of study reveals about the effectiveness of CON programs

Certificate-of-need (CON) laws require healthcare providers to seek permission from state regulators before they offer new services, expand facilities, or invest in technology. While the original hope was that CON laws would restrain healthcare costs, increase healthcare quality, and improve access to care for poor and underserved communities, a large body of academic research suggests that CON laws have instead limited access, degraded quality, and increased cost.

Despite this poor track record, CON laws remain in 35 states and the District of Columbia, keeping millions of Americans from getting the care they need. 

Given the evidence from academic research and the experience of states which have undertaken reform, state policymakers who wish to increase patient access to high-quality, lower-cost care would be well advised to eliminate their entire CON programs. Reforming CON laws also represents a valuable step policymakers can take to improve the responsiveness of their healthcare systems in times of crisis. See below for research related to CON laws and the COVID-19 pandemic.

Which States Have Certificate-of-Need Laws?

As of May 2021, 35 states and the District of Columbia required providers to obtain a CON before offering at least one healthcare service. Two additional states, Minnesota and Wisconsin, set numerical caps on certain services such as the total number of hospital beds and nursing home beds. Other states require a CON for ground and air aPeoplembulance services, though these laws are often found in transportation statutes, and their effects on health outcomes are not as well studied. Hawaii has the highest number of CON restrictions (28) of any state, with North Carolina (27) and the District of Columbia (25) following close behind. Eleven states have removed all CON laws or caps: California, Colorado, Idaho, Kansas, New Hampshire, North Dakota, Pennsylvania, South Dakota, Texas, Utah, and Wyoming.

Options For Reforming Certificate-of-Need Laws

Many legislators see CON repeal as a common-sense way of improving healthcare in their states. While research shows full repeal is best, there are still ways to make meaningful reform happen even when full repeal is not feasible. Click on one of the reform options below to learn more about it.

    New York was the first state to institute a CON program in 1964, followed by Rhode Island, Maryland, California, and 22 other states over the next 10 years. In 1974, Congress passed the National Health Planning and Resources Development Act, requiring states to implement CON requirements in order to receive funding through certain federal programs. Louisiana was the only state not to implement a CON program during this time. But in 1986—as evidence mounteed that CON laws were failing to control healthcare costs or improve quality or access—the federal government repealed the CON mandate, and many states immediately began retiring their CON programs. Since then, 15 states have done away with their CON regulations. A majority of states still maintain CON programs, however, and vestiges of the National Health Planning and Resources Development Act can be seen in the justifications that state legislatures offer in support of these regulations, despite evidence they are ineffective. Learn more about how CON laws have changed over the past several decades.

    No. CON regulation explicitly limits the establishment and expansion of healthcare facilities and is associated with fewer hospitals, ambulatory surgical centers, dialysis clinics, and hospice care facilities. It is also associated with fewer hospital beds and decreased access to medical imaging technologies. Residents of CON states are more likely than residents of non-CON states to travel further to obtain medical services and CON laws favor incumbent hospitals in the market for services.

    No. CON programs are associated with fewer hospitals overall, but also with fewer rural hospitals, rural hospital substitutes, and rural hospice care. Residents of CON states must drive further to obtain care than residents of non-CON states.

    Sources: Cutler, Huckman, and Kolstad (2010); Carlson et al. (2010); Stratmann and Koopman (2016)

    Mostly likely not. While early research was mixed, more recent research suggests that deaths from treatable complications following surgery and mortality rates from heart failure, pneumonia, and heart attacks are all significantly higher among hospitals in CON states than hospitals in non-CON states. Also, in states with especially comprehensive CON programs, patients are less likely to rate hospitals highly.

    Sources: Stratmann and Wille (2016)

    No. There is no difference in the provision of charity care between states with CON programs and states without them, and CON regulation is associated with greater racial disparities in access to care.

    Sources: DeLia et al. (2009); Stratmann and Russ (2014)

    No. CON regulations have a disproportionate effect on nonhospital providers of medical imaging services and are associated with 14 percent fewer total ambulatory surgical centers.

    Sources: Stratmann and Baker (2017); Stratmann and Koopman (2016)

    No. By limiting supply, CON regulations increase per-unit healthcare costs. Even though CON regulations might reduce overall healthcare spending by reducing the quantity of services that patients consume, the balance of evidence suggests that CON laws actually increase total healthcare spending.
