Are Integrated Plan Providers Associated With Lower Premiums on the Health Insurance Marketplaces?

As the health insurance industry becomes more consolidated, hospitals and health systems have started to enter the insurance business. Insurers are also rapidly acquiring providers. Although these "vertically" integrated plan providers are small players in the insurance market, they are becoming more numerous. The health insurance marketplaces (HIMs) offer a unique setting to study integrated plan providers relative to other insurer types because the HIMs were designed to promote competition. In this descriptive study, the authors compared the premiums of the lowest priced silver plans of integrated plan providers with other insurer types on the 2015 and 2016 HIMs. Integrated plan providers were associated with modestly lower premiums relative to most other insurer types. This study provides early insights into premium competition on the HIMs. Examining integrated plan providers as a separate insurer type has important policy implications because they are a growing segment of the marketplaces and their pricing behavior may influence future premium trends.

Temporal Analysis of Market Competition and Density in Renal Transplantation Volume and Outcome.

BACKGROUND: Kidney transplant centers are distributed unevenly throughout 58 donor service areas (DSAs) in the United States. Market competition and transplant center density may affect transplantation access and outcomes. We evaluated the role of spatial organization of transplant centers in conjunction with market competition in the conduct of kidney transplantation. METHODS: The Scientific Registry of Transplant Recipients was queried for market characteristics associated with kidney transplantation between 2003 and 2012. Market competition was calculated using the Herfindahl Hirschman Index. Kidney transplant centers were geocoded to measure spatial organization by the average nearest neighbor (ANN) method. Kidney quality was assessed by kidney donor risk index. A hierarchical negative binomial mixed effects model tested the relationship between market characteristics and annual kidney transplants by DSA. RESULTS: About 152,071 kidney transplants were performed at 229 adult kidney transplant centers in 58 DSAs. Greater market competition was associated with kidney transplant center spatial clustering (P < 0.001). In multivariable analysis, more kidney transplant centers (incidence rate ratio [IRR], 1.04; P = 0.005), 100 more new listings (IRR, 1.02; P = 0.003), 100 more deceased donors (IRR, 1.23; P < 0.001), 100 more new dialysis registrants (IRR, 1.01; P < 0.001), and higher kidney donor risk index (IRR, 1.98; P < 0.001) were associated with increased kidney transplants. CONCLUSIONS: After controlling for market characteristics, larger numbers of kidney transplant centers were associated with more kidney transplants and increased utilization of deceased donor kidneys. This underlines the importance of understanding geography as well as competition in improving access to kidney transplantation.

The structure of risk adjustment for private plans in Medicare.

Medicare bases its risk adjustment method for Medicare Advantage plan payment on the relative costs of treating various diagnoses in traditional Medicare. However, there are many reasons to doubt that the relative cost of treating different diagnoses is similar between Medicare Advantage plans and traditional Medicare, including the varying applicability of care management methods to different diagnoses and the varying degrees of market power among suppliers of services to plans. We use internal cost data from a large health plan to compare its cost of treating various diagnoses with Medicare's reimbursement. We find substantial variability across diagnoses, implying that the current risk adjustment system creates incentives for Medicare Advantage plans to favor beneficiaries with certain diagnoses, but find no consistent relationship between the costliness of the diagnosis and the difference between reimbursement and cost.

Effects of health savings account-eligible plans on utilization and expenditures.

OBJECTIVE: To assess the impact of a health savings account (HSA)-eligible plan on utilization and expenditures in an employer-sponsored Midwestern health plan which offered a traditional plan from 2003 through 2004 that was fully replaced by an HSA-eligible plan in 2005 and 2006. STUDY DESIGN: Retrospective pre-post design with a control group. METHODS: Medical and pharmacy claims of plan members younger than 65 years who were continuously enrolled throughout the 4-year study period were used to evaluate the impact of switching to the HSA-eligible plan. Expenditure and utilization measures were compared with those for a control group covered by employers in the same industry and geographic location, while controlling for patient characteristics. RESULTS: The HSA-eligible plan was associated with significantly lower total expenditures (-17.4%), fewer and less costly office visits (-13.6% and -20.3%, respectively), fewer emergency department (ED) visits (-20.1%), lower pharmacy expenditures (-29.2%), lower expenses per drug (-27.9%), a reduced likelihood of mammograms (odds ratio [OR] = 0.55, P <.05) and Papanicolaou tests (OR = 0.66, P <.05), and a borderline significant reduction in routine physical exams (OR = 0.76, P <.10). The HSA-eligible plan also was associated with increased outpatient facility expenditures (5.1%, P <.05). CONCLUSION: Employer-sponsored HSA-eligible plans appear to be associated with lower healthcare expenditures and/or utilization, particularly for office visits, ED visits, and pharmacy. However, they also may discourage preventive care, leading to increased long-term medical costs. Employers offering HSA-eligible plans should ensure that there are no financial barriers for preventive services.

Health plan competition for Medicaid enrollees based on performance does not improve quality of care.

Incentives to improve the quality of care provided in Medicaid managed care plans are increasingly common and take many forms. One is a pay-for-performance program that automatically assigns new enrollees to better-performing Medicaid plans in California. Our qualitative and quantitative study of this program examined the expected and actual impacts of the performance incentive on all areas of care. We compared quality outcomes in plans included in the pay-for-performance, "auto-assignment" incentive and comparable outcomes in plans that were not included. We found that quality did not improve significantly faster in plans included in the incentive scheme. Combined with some evidence of negative impact on other areas of care, the findings raise questions about the usefulness of this program in California Medicaid, and about similar programs in other states.

Consumer-oriented health care reform strategies: a review of the evidence on managed competition and consumer-directed health insurance.

CONTEXT: For many years, leading health care reform proposals have been based on market-oriented strategies. In the 1990s, a number of reform proposals were built around the concept of "managed competition," but more recently, "consumer-directed health care" models have received attention. Although price-conscious consumer demand plays a critical role in both the managed competition and consumer-directed health care models, the two strategies are based on different visions of the health care marketplace and the best way to use market forces to achieve greater systemwide efficiencies. METHODS: This article reviews the research literature that tests the main hypotheses concerning the two policy strategies. FINDINGS: Numerous studies provide consistent evidence that consumers' health plan choices are sensitive to out-of-pocket premiums. The elasticity of demand appears to vary with consumers' health risk, with younger, healthier individuals being more price sensitive. This heterogeneity increases the potential for adverse selection. Biased risk selection also is a concern when the menu of health plan options includes consumer-directed health plans. Several studies confirm that such plans tend to attract healthier enrollees. A smaller number of studies test the main hypothesis regarding consumer-directed health plans, which is that they result in lower medical spending than do more generous plans. These studies find little support for this claim. CONCLUSIONS: The experiences of employers that have adopted key elements of managed competition are generally consistent with the key hypotheses underlying that strategy. Research in this area, however, has focused on only a narrow range of questions. Because consumer-directed health care is such a recent phenomenon, research on this strategy is even more limited. Additional studies on both topics would be valuable.

Strengths and limitations of competitive versus non-competitive models of integrated capitated fundholding.

Integrated budget-holding (fundholding) based on risk-adjusted capitation is commonly proposed as a central element of health system reform. Two contrasting models have been developed: the competitive model where fundholders or health plans compete for enrollees; and the non-competitive model, where plan membership is determined according to an objective attribute such as place of residence. Under the competitive model, efficiency is sought through consumer choice of plan. A range of regulatory elements may also be introduced to moderate undesirable elements of competition. Under the non-competitive model, efficiency is achieved through government regulation and the fact that the fundholder has continuing responsibility for the health of a defined population, supported by micro-management tools (such as quality assurance and selective payment arrangements). In theory, the non-competitive model encourages population-based health services planning. While both models assume risk-adjusted capitated funding, the requirements of any formula are more stringent under the competitive model. Economic theory, as well as documented health system experience, can help identify the relative strengths and limitations of each model. Concerns with the competitive model relate primarily to the capacity to develop robust risk adjusters for capitation sufficient to reduce the incentives for patient risk selection. Possible reductions in the quality of care are also a concern, compounded by difficulties for consumers in discriminating between plans. Efficiency under the non-competitive model requires a strong and appropriate regulatory/policy framework and effective use of micro-management tools. Funding equity objectives can be met through either model by the adoption of income-related contributions, but under the competitive model this may be compromised by incentives for the fundholders to select low-risk patients. Evidence drawn from regional fundholding in New South Wales (NSW, Australia), the US Veterans Health Agency and the literature on managed care in the USA illustrate these concerns. The problem of risk selection in the competitive model is a major theoretical concern, confirmed by the empirical evidence. This, together with concerns regarding other aspects of performance, suggests that the non-competitive model may be preferable, at least as an interim step in reform in public or mixed systems. Future research on this issue is clearly required.

The health plan choices of retirees under managed competition.

OBJECTIVE: To investigate the effect of price on the health insurance decisions of Medicare-eligible retirees in a managed competition setting. DATA SOURCE: The study is based on four years of administrative data from the University of California (UC) Retiree Health Benefits Program, which closely resembles the managed competition model upon which several leading Medicare reform proposals are based. STUDY DESIGN: A change in UC's premium contribution policy between 1993 and 1994 created a unique natural experiment for investigating the effect of price on retirees' health insurance decisions. This study consists of two related analyses. First, I estimate the effect of changes in out-of-pocket premiums between 1993 and 1994 on the decision to switch plans during open enrollment. Second, using data from 1993 to 1996, I examine the extent to which rising premiums for fee-for-service Medigap coverage increased HMO enrollment among Medicare-eligible UC retirees. PRINCIPLE FINDINGS: Price is a significant factor affecting the health plan decisions of Medicare-eligible UC retirees. However, these retirees are substantially less price sensitive than active UC employees and the non-elderly in other similar programs. This result is likely attributable to higher nonpecuniary switching costs facing older individuals. CONCLUSIONS: Although it is not clear exactly how price sensitive enrollees must be in order to generate price competition among health plans, the behavioral differences between retirees and active employees suggest that caution should be taken in extrapolating from research on the non-elderly to the Medicare program.

Medicare program; waiver requirements and solvency standards for provider-sponsored organizations--HCFA. Interim final rule with comment period.

This interim final rule with a request for comments implements authority to waive, in the case of provider-sponsored organizations (PSOs) that meet certain criteria, the requirement that Medicare + Choice organizations be licensed by a State as risk-bearing entities. The waivers will be approved only under certain conditions where the State has denied or failed to act on an application for licensure. This rule also establishes solvency standards that certain entities must meet to contract as PSOs under the new Medicare + Choice program. These standards apply to PSOs that have received a waiver of the requirement that Medicare + Choice organizations be licensed by a State as risk-bearing entities.

Medicare program; HCFA market research for providers and other partners--HCFA. General notice with comment period.

This notice seeks public comments on information needs of Medicare risk contract health maintenance organizations (HMOs) and competitive medical plans (CMPs) and communication strategies that could improve the effectiveness and efficiency of the risk contract program. Under section 4002 of the Balanced Budget Act of 1997, and with the implementation of the Medicare + Choice program, all HMOs and CMPs will contract with HCFA under requirements of the Medicare + Choice program. The information sought in this notice will facilitate future changes in the contracting program, as well as improve information needs and communication strategies under the current risk program. Respondents should prioritize issues raised in the preliminary research and identify and additional areas of information needs and best communication strategies. This initiative is one component of our overall effort to develop a comprehensive communication strategy with Medicare providers and HMOs/CMPs and to develop innovative approaches that will assist all program participants to obtain and use information in the most accessible and effective manner. Preliminary research on the information needs of Medicare risk contract HMOs and CMPs and effective communication strategies has identified a number of areas in which we could provide additional information and potential strategies for communicating that information effectively.
