In most states, hospitals negotiate payment rates with each payer. Payers can include private health insurance plans, self-insured employer plans, and uninsured individuals, and may also include public payers like Medicaid and Medicare.1,2
Hospital rate setting is a system in which an authority, usually a state agency, establishes uniform rates for hospital services for multiple payers. When every payer in the state participates—as is the case in Maryland—it is referred to as all-payer hospital rate setting.
This paper updates Hub Research Brief No. 1 (March 2015; first updated August 2017) with results from Maryland’s most recent Medicare waiver, and the state’s progress towards the Triple Aim: Improving the individual experience of care, improving population health and reducing per capita costs.
Hospital care (inpatient and outpatient) accounts for about one-third of national healthcare spending.3 Moreover, hospital spending is expected to increase by 5.7 percent per year, on average, during 2020-2027—far exceeding the general rate of inflation.4 Annual increases in hospital spending have been identified as a major driver of medical spending, and even a modest decrease can mean annual savings of billions of dollars.5 Moreover, in many areas of the county hospitals have achieved enormous market power, both by acquiring other hospitals but also by acquiring physician practices. Variations in market power have resulted in tremendous variation in the prices charges by private payers for similar hospital services, sometimes far exceeding the cost to provide services.6 The prevalence of price discrimination can leave smaller payers and the uninsured paying much higher prices for hospital services. Such a system also adds to administrative waste and inequitable health outcomes.7
A hospital rate setting system can potentially contain costs, increase equity and reduce administrative waste by establishing payment levels and controlling the rate of growth of those payment levels over time. In addition, a rate setting system can provide a platform for aligned approaches to improve the quality and equity of care. When quality incentives are built into the payment rates of every payer, they apply to the full population of patients, rather than just an individual insurer's population, increasing the incentive to deliver care more efficiently and improve quality. Because spending flows and performance metrics are publicly debated, these systems can provide better price and quality transparency to the public.
All-payer systems, such as Maryland's, require a federal waiver in order for the state's rate setting agency to replace Medicare's payment rules with its own. While the form of this waiver has evolved over time, it generally requires that the state's payment rules not exceed the amount that Medicare would have spent under its regular payment rules for hospitals.
A study of Maryland's system has found that rate setting can be successful in controlling the rate of hospital cost increases.8 However, success depends on the way in which rate setting is implemented, as well as regulators’ ability to enforce the rates and impose penalties for noncompliance.
Maryland Model (1971-2013): Formulation and Evolution of the All-Payer Rate Setting System
Like many other states, Maryland established its hospital rate setting system in the 1970s. The Maryland Hospital Association initially proposed rate regulation as a means of financing the growing levels of hospital uncompensated care. In response, the state established the Health Services Cost Review Commission (HSCRC), a state agency with broad powers of hospital rate setting and public disclosure. With a 1977 Medicare waiver, Maryland added Medicare rates to their system, creating a true “all-payer” approach, with all public and private payers paying on the same basis.
During these early decades using the all-payer rate system, Maryland has effectively moderated per admission spending growth and improved the financial stability of the state’s hospitals.11 Average hospital cost per admission in Maryland went from 26 percent greater than the national average in 1976 to 2 percent lower in 2007.12 Further, the system helped create a more equitable spread of the costs of uncompensated care and helped eliminate cost-shifting among payers.13
However, while the system effectively reduced per-admission costs, Maryland faced challenges with the original model. Hospital admissions in Maryland increased at a rate of 2.7 percent from 2001 to 2007 compared to the national average of 1 percent, indicating that the approach created perverse incentives for high volume.14
Total Patient Revenue System (TPR) Pilot Program (2008-2010; 2010-2013)
To address the increase in hospital admissions, in 2008 Maryland piloted a global budget system for hospitals as an incentive to reduce unnecessary admissions and readmissions. The idea was that fixed, predictable revenues tied to performance measures would eliminate incentive for unnecessary admissions and give hospitals the flexibility to invest in care improvements. Participating hospitals received a fixed global budget covering all outpatient and inpatient services, based on hospitals’ revenue from the previous year (see Figure 2). Prior-year revenue was then adjusted by an estimate of underlying cost inflation, demographic changes in the hospitals’ service areas and relative performance on specific quality measures.15
Ten rural community hospitals participated in the three-year pilot called the Total Patient Revenue System (TPR) program. Overall, the TPR hospitals successfully reduced the number of admissions and readmissions, as well as emergency department visits. For example, between 2010 and 2014, a western Maryland hospital reduced inpatient admissions by 32 percent and reduced readmissions by 42 percent.16 A 2019 study comparing TPR hospitals to non-TPR Maryland hospitals found that emergency department admission rates, ambulatory surgery visit rates, and outpatient visits and service rates fell by 12 percent, 45 percent, and 40 percent, respectively.17
But the findings are mixed. A second 2019 study found little impact on inpatient admissions, although it similarly concluded that outpatient and non-emergency department (ED) visits decreased.18 This study compared population-level utilization between ZIP code areas assigned to a TPR hospital service area or a non-TPR hospital service area. Three years after implementation, researchers found no significant changes in inpatient admissions, either overall or discretionary. In addition, researchers found a 15 percent decrease in non-emergency department outpatient visits (including outpatient clinic visits and outpatient surgeries.
Global Budget Model (2014-2018): Making Progress Towards the Triple Aim
Based on learnings from the global budgeting TPR pilot, in 2014, Maryland launched a new initiative to modernize the rate setting system. Under a new five-year Medicare waiver from CMS, the rate setting system evolved to be based on containing total, annual per capita hospital cost growth rather than payment per admission or per episode.
The waiver required that Maryland transition at least 80 percent of hospital revenue to “population-based payment methods,” like the TPR hospitals. In addition, Maryland was required to meet the following goals:19
Early results were mixed. One study that compared changes in utilization among Medicare beneficiaries in Maryland with out-of-state control groups in the first two years had inconsistent results.20 Researchers found no clear evidence that hospitals met their budgets by reducing hospital utilization or enhancing primary care beyond changes that would have been expected without a global budget system.
However, by the fourth year of the waiver, the program was performing well against the program benchmarks. A 2019 evaluation shows that Maryland had already met or exceeded most waiver requirements by year three.21
Medicare Spending and Utilization
Commercial Payer Spending and Utilization
Maryland patients with commercial plans experienced 6.1 percent slower growth in hospital expenditures relative to a comparison group; however, total spending did not decrease due to offsetting higher use of professional services.26
The combined rate of ED visits and observation stays declined for commercial plan members, which researchers believe could be due to hospitals' attempts to move ED use to other settings.27
Other data show hospitals have expanded efforts to help patients transition home or to post-acute settings after discharge. They are using case managers in EDs to connect patients to primary care and other resources, and proactively treating chronic conditions such as diabetes, heart disease and pulmonary disease.28 Furthermore, by the third year of this program, hospitals were increasing their focus on “high-risk, high-cost patients,” who frequently have complex social and medical needs that may require higher use of hospital services, such as individuals with severe mental illnesses or substance use disorders.29 Outcomes improved for beneficiaries with multiple chronic conditions and beneficiaries dually eligible for Medicare and Medicaid relative to other Medicare beneficiaries during the all-payer model period.30 Also during this time, hospitals reduced potentially preventable complications, such as Clostridium Difficile infections and decubitus ulcers, by 48 percent, sailing past the 5-year target.31
On the other hand, coordination of care with community providers, as measured by follow-up visits after hospital discharge, did not improve.32 Lack of provider engagement and provider shortages were cited as barriers to improving care coordination.
Maryland Model (2019-2027): Implementing the Total Cost of Care Model
Encouraged by the success of the global budgeting model, Maryland submitted a progression plan to CMS, termed the Total Cost of Care (TCOC) Model. Under the expansion, the all-payer model applies to some doctors' visits and other outpatient services, such as long-term care. Community healthcare providers are able to choose whether they want to participate in the model. The TCOC model provides tools and incentives for clinicians, hospitals, nonhospital facilities, and specialists to coordinate with each other and provide parient-centered, preventative, and timely care, while ensuring their financial stability.33
While Maryland's regulatory authority is limited to hospitals and Medicaid services, the progression plan calls for engaging physicians and other clinicians in voluntary efforts to redesign care. In addition, the plan places a renewed emphasis on population health improvement, particularly for complex, high-need patients.
The 8-year TCOC waiver is the first model in which CMS has held a state fully at risk for the total cost of care for Medicare beneficiaries—the financial targets are more than $1 billion in Medicare savings by 2023.34 The Total Cost of Care model includes three programs:
The Total Cost of Care model also focuses heavily on improving state-wide population health. Maryland selected six high-priority areas: Substance-Use Disorder, Diabetes, Hypertension, Obesity, Smoking, and Asthma. Noting that improving population health will increase Medicare savings in the long- and short-term, CMS will use an Outcomes-Based Credits framework to grant Maryland credits for the state's performance on these population health measures and targets. These credits will count towards Maryland's Total Cost of Care savings target and will be commensurate with the return on investment that Medicare anticipates receiving from the state's improved performance.
Though Maryland's evolving approach to hospital reimbursement has realized many successes, researchers have identified challenges to suceeding under the most recent model, namely bolstering effective communication, partnership, and collaboration between hospitals and nonhospital clinicians and facilities. In addition, close coordination between federal and state partners must play a key role in the Total Cost of Care model.35
For decades, Maryland has been the only state with an all-payer hospital rate setting system. Several researchers suggest the following as to why Maryland's system has endured:
The Maryland all-payer hospital rate setting system lowered costs for patients and improved quality, particularly for high-cost, high-need patients and the most recent evaluation found that patient experience stayed the same, compared to a prior period.39
While there is no evidence of this occurring in Maryland, possible downsides to guard against under global budgets include hospital avoidance of costly or complex patients in order to meet spending targets.
More generally, consumer benefits are more likely to be realized if:
The rate setting process uses a public, multi-stakeholder process to establish rates and monitor hospital performance. Consumers and their advocates should have a formal, supported role in the process.
A robust data collection and analysis system is implemented and fully funded (out of the savings the state will realize) in order to measure the impacts on patients. Providers must receive timely, actionable reports on their performance. This data system should incorporate not only claims data but also other information, such as patient complaints made to hospitals, insurers or regulators, and patient experience survey data.
Although theory strongly predicts administrative cost savings under this system, research is lacking to measure the impact of the all-payer hospital rate setting model on administrative costs. In a 2011 article, researchers created a model of potential savings in Vermont if the state adopted an all-payer system for hospitals. The model predicted a 7.3 percent decrease in administrative costs.40 But stronger evidence is needed to understand the impact of all-payer rate setting on hospital and insurer administrative spending compared to more conventional payment approaches.
Like all comprehensive reforms, establishing an effective all-payer rate setting program presents a number of challenges for states.
In addition, regulator experts warn that it can take “three or four years for [hospitals] to make the paradigm shift into a population health approach.”43 Despite these challenges, other states are following this model closely. In 2018, no fewer than 26 states had applied to participate in a global budgeting workshop for rural hospitals.44
Currently, the effort that comes most closely to emulating the Maryland's model is the Pennsylvania Rural Health Model, which began in January 2017. Under the program, participating rural hospitals are paid based on all-payer global budgets. The program pays the hospitals a fixed monthly amount and allows them to use the money how they think best serves their community. Those global payments come from several payers, including private and public insurers. The approach differs from Maryland: The private plans are not required to publicly disclose their payment rates and the state won't set the rates. Nearly half of all rural hospitals in Pennsylvania are operating with negative margins and are at risk of closure. A goal for the program is predictable revenue and spending flexibility to modify the hospital's mission to better meet community needs and stabilizing financing.
The success of Maryland's all-payer model provides a roadmap for how to eliminate the negative incentives of fee-for-service systems by substituting a population-based system of payment and care delivery, which is consistent with the goals of the Triple Aim and many of CMS's new payment initiatives. Hospital rate setting systems can improve patient outcomes and provide predictable revenue for hospitals, while still producing overall system savings.
It is critical that states contemplating a rate setting system similar to Maryland's include input from stakeholders, including a strong voice from consumers, providers and other organizations involved in payment and costs for care. Additionally, the rate setting body must have access to a robust data collection and analysis system to support implementation and the monitoring of progress. These strategies help to ensure the rate setting program is reducing costs and improving the patient's hospital care experience
1. Bringing in public payers requires a waiver from the federal Medicare program and also that the state Medicaid system agreed to be a part of the payment system. In Vermont, for example, Medicaid decided not to participate in a proposed multi-payer system that was designed for them. Medicaid has to agree or be mandated to be a part of the system by the legislature.
