The Oregon Health Plan was created to be a sustainable program that could weather budgetary storms without having to cut enrollees from Medicaid. A 2003 redesign of the program increased premiums, raised cost sharing, and imposed rigid premium payment deadlines for members in the “Standard” version of the program but not for members of the “Plus” version. This paper adds two years of longitudinal data to a previous study on the impacts of these changes. It shows that the redesign was a key factor driving a 77 percent disenrollment rate in the Standard program, from a high of 104,000 enrollees in February 2003 to just 24,000 by the end of the study period, November 2005. Those who were in the Standard plan when the reduced benefits and higher member costs went into effect were also nearly twice as likely to have unmet health care needs compared to those in the Plus plan.
Impact In Oregon
The 2003 Medicaid redesign had profound effects on the Oregon Health Plan Standard population. In the months immediately after the redesign, many of those enrolled in the Standard plan left the program entirely. These people, as well as those who remained in the program, subsequently experienced greater unmet health care needs, reduced use of care, more medical debt, and greater household financial strain than members of the Plus plan, to whom the redesign did not apply.
Changes to the cost-sharing structure, which consisted of mandatory copays, increased monthly premiums for some members, and tightened administrative rules including a loss of coverage for nonpayment of premiums, affected Standard plan members in two main ways. First, the changes in premium rules led to heavy disenrollment initially, and those who left often experienced periods of uninsurance throughout the study time frame along with the other changes, such as higher rates of unmet need.
Second, even after gaps in coverage and other known differences between the populations were controlled for, members of the Standard plan experienced poorer outcomes than members of the Plus plan. This suggests that even for those who managed to stay enrolled in spite of higher premiums, increased cost sharing in the form of mandatory copays may have limited members’ access to and use of care, in addition to having a direct financial impact.
Implications For Other States
These findings contain lessons for other states, particularly as they implement Medicaid expansions under the Affordable Care Act. Some states already provide Medicaid coverage to nonelderly adults with incomes up to 133 percent of the federal poverty level, but the act is expected to result in more than seventeen million Americans’ becoming eligible for Medicaid by 2014.
Cost Sharing:
The first lesson is that although strict cost-sharing rules might be an appealing way to offset the costs associated with increased Medicaid enrollment, they create barriers for people to get and keep insurance.
Our data show that Medicaid members are sensitive to even small cost-sharing increases. Coupling those increases with stricter payment policies can create widespread coverage loss. In fact, previously published analyses of this study’s data suggest that the most vulnerable Standard plan members were the most likely to leave in response to changes in cost-sharing rules.
This fact is particularly important because recent analyses of census data suggest that nearly half of those who will become eligible for Medicaid under the new federal eligibility guidelines have incomes below 50 percent of the federal poverty level. In this newly eligible, very-low-income population, offering payment flexibility and exemptions might help ensure that the neediest benefit from coverage expansion.
Coverage Gaps:
Second, those who leave Medicaid in response to changes in cost-sharing rules are very likely to experience major coverage gaps. Over time, they have more difficulty meeting their health care needs, accumulate more medical debt, and experience greater financial strain than those who stay insured.
Unmet Need:
Third, even among those who remain enrolled, increased cost sharing in the form of copayments may result in greater unmet need for health care, along with increased household financial strain and medical debt. It may also greatly depress health care use. Although reducing unnecessary use is one of the goals of cost sharing, when reduced use is paired with an increase in unmet need, the question arises, does the reduction represent care that is needed or that would help prevent costly complications in the future?

Currently there is a fixation in the health policy community on designing plans that require a significant financial contribution from the beneficiary on the theory that high health care costs can be moderated by making patients more sensitive to those costs.
Many studies have now confirmed that these plan designs impair access to health care because of affordability issues, and result in impaired health outcomes. Although this is certainly true for those with moderate incomes, this new study confirms once again that it is particularly disastrous for low-income individuals.
As a result of the Patient Protection and Affordable Care Act (PPACA), in 2014 an estimated 17 million individuals will be added to state Medicaid programs. Because of tight budgets, states are already seeking federal waivers that would relax the PPACA requirements.
It is likely that most states will soon seek waivers for their Medicaid programs to allow flexibility in innovation. The innovations will not be for the purpose of assisting patients in getting the care that they need, but rather they will be for the purpose of reducing the Medicaid component of the state budgets.
PPACA has already enshrined high cost-sharing by establishing low-actuarial value plans (high deductibles, etc.) as the standard within the state insurance exchanges. The temptation for states to expand this concept to Medicaid will be great.
The Oregon Health Plan may have provided an important lesson for other states, but that won’t prevent them from doing the same. After all, making price-sensitive shoppers out of people who have no money is effective in reducing health care spending, even if it does result in further financial hardship, physical suffering, and even death, and dead patients are the least expensive of all.
