Changes in care associated with integrating Medicare and Medicaid for dual-eligible individuals.
This study’s objective was to evaluate changes in care associated with integrating Medicare and Medicaid coverage in a fully integrated dual-eligible special needs plan (FIDE-SNP) in Pennsylvania. This cohort study used a difference-in-differences analysis compared changes in care between 2 cohorts of dual-eligible individuals: (1) an integration cohort composed of Medicare Dual Eligible Special Needs Plan enrollees who joined a companion Medicaid plan following a 2018 state reform mandating Medicaid managed care (leading to integration), and (2) a comparison cohort with nonintegrated coverage before and after the start of Medicaid managed care. Analyses were conducted of outcomes in 4 domains: use of home- and community-based services (HCBS), care management and coordination, hospital stays and postacute care, and long-term nursing home stays. The study included 7967 individuals in the integration cohort and 3832 individuals in the comparison cohort. HCBS use increased differentially in the integration vs comparison cohorts by 0.61 days/person-month. However, integration was not associated with changes in care management and coordination, including medication use for chronic conditions (-0.02 fills/person-month) or follow-up outpatient care after a hospital stay (-0.01 visits/hospital stay). There was no significant difference in hospital stays between the cohorts.

The impact of Medicaid expansion on spending and utilization by older low-income Medicare beneficiaries.
This study examined indirect spillover effects of Affordable Care Act (ACA) Medicaid expansions to working-age adults on health care coverage, spending, and utilization by older low-income Medicare beneficiaries. The authors used data from the 2010-2018 Health and Retirement Study survey linked to annual Medicare beneficiary summary files. They estimated individual-level difference-in-differences models of total spending for inpatient, institutional outpatient, physician/professional provider services; inpatient stays, outpatient visits, physician visits; and Medicaid and Part A and B Medicare coverage. They also compared changes in outcomes before and after Medicaid expansion in expansion versus nonexpansion states. The sample included low-income respondents aged 69 and older with linked Medicare data, enrolled in full-year traditional Medicare, and living in the community. ACA Medicaid expansion was associated with a 9.8 percentage point increase in Medicaid coverage, a 4.4 percentage point increase in having any institutional outpatient spending, and a positive but statistically insignificant 2.4 percentage point change in Part B enrollment.

Use of intergovernmental transfers-based Medicaid supplemental payments to boost nursing home finances: evidence from Indiana nursing homes.
The objective of this study was to estimate the effect of participation in the intergovernmental transfers-based Medicaid supplemental payment program on nursing home revenue and expenditures. Data was taken from all Medicare and Medicaid-certified nursing homes in Indiana from 2009-17. The findings indicated that nursing homes owned or operated by nonstate governmental organizations received a fraction of the total supplemental payments on average, but the authors observed increased payments in later years. Participating nursing homes did not increase clinical expenses. The authors concluded that these findings raised questions regarding the transparency of financing arrangements between nonstate governmental organizations and nursing homes and the need to link supplemental payments to clinical expenses.

Effects of a Medicaid dental coverage "cliff" on dental care access among low-income Medicare beneficiaries.
Medicare beneficiaries with income levels slightly exceeding the thresholds of eligibility for Medicaid have few affordable options for dental coverage. This gap results in a dental coverage “cliff” above these thresholds. The purpose of this study was to assess how a sudden drop-off in dental coverage from Medicaid impacts access to dental care in low-income Medicare beneficiaries. The researchers studied low-income community resident Medicare recipients whose incomes were within approximately 75 percentage points of state-specific Medicaid income eligibility thresholds. The study found that Medicare beneficiaries whose income was higher than Medicaid eligibility thresholds were 5.0 percentage points more likely to report challenges accessing dental care because of cost concerns or a lack of insurance than beneficiaries below the thresholds.

Are online reviews of assisted living communities associated with patient-centered outcomes?
The purpose of this study was to explore the relationship between assisted living (AL) online quality review ratings and AL residents' home time. The researchers identified Medicare beneficiaries who entered AL communities in 2018, with the main outcome of resident home time in the year after AL admission. Additional outcomes were the percentage of time spent in emergency room, inpatient hospital, nursing home, and inpatient hospice. The study sample included 59,831 residents in 12,143 ALs. AL online Google reviews for 2013-2017 were linked to 2018-2019 Medicare data. AL average rating score and rating status were generated using Google reviews. The study found that from 2013 to 2017, ALs received an average rating of 4.1 on Google, with a standard deviation of 1.1. Each one-unit increase in the AL's average online rating was associated with an increase in residents' risk-adjusted home time by 0.33 percentage points. Residents in high-rated ALs had a 0.64 pp increase in home time compared with residents in ALs without ratings. Thet study concluded that higher online rating scores were positively associated with residents' home time, and a lack of ratings was related with decreased home time.

Advancing health equity through partnerships of state Medicaid agencies, Medicaid managed care organizations, and health care delivery organizations.
This article explored how multi-stakeholder teams operationalized the Roadmap to Advance Health Equity model during the early stages of its implementation. Semi-structured interviews were conducted with representatives from multi-stakeholder teams from state Medicaid agencies, Medicaid managed care organizations, and health care delivery organizations in seven US states about their experiences. The team representatives shared practical strategies for implementing the Roadmap to Advance Health Equity, which the authors believed could inform future efforts to build intra- and inter-organizational cultures of equity and integrate health equity into care delivery and payment systems.

Preparing for participation in the centers for Medicare and Medicaid Services' bundle care payment initiative-advanced for major bowel surgery.
This study aimed to assess where the largest opportunities for care improvement lay with the bundled payment reimbursement model and how best to identify patients at high risk of suffering costly complications, including hospital readmission. The authors used a cohort of patients from 2014 and 2016 who met inclusion criteria for the Major Bowel Bundled Payment Program and performed a cost analysis to identify opportunities for improved care efficiency. Using the results, they identified readmissions as a target for improvement and then assessed whether the American College of Surgeons' National Surgical Quality Improvement Program surgical risk calculator (ACS NSQIP SRC) could accurately identify patients within the bundled payment population who were at high risk of readmission using a logistic regression model. Patients who were readmitted within 90-days post-surgery were 2.53 times more likely to be high-cost (>$60,000) then non-readmitted patients. However, the ACS NSQIP SRC did not accurately predict patients at high risk of readmission within the first 30 days post-surgery.

Characteristics, utilization, and concentration of outpatient care for dual-eligible Medicare beneficiaries.
The purpose of this study was to describe the distribution of outpatient care for dual-eligible Medicare beneficiaries ("duals") and characterize the intensity of outpatient care utilization of duals vs non-dual-eligible beneficiaries ("nonduals"). The researchers assessed the distribution of outpatient care across physician practices and compared the use of different outpatient services between duals and nonduals. The study found that nearly 80% of outpatient visits for duals were provided by 35% of practices. Compared with low-dual and no-dual practices, high-dual practices served more patients, with morhe comorbidities. Duals had 2 less outpatient visits per year compared with nonduals with substantially fewer subspecialty care visits despite having more comorbidities.

Differences in care between special needs plans and other Medicare coverage for dual eligibles.
This study compared access to, use of, and satisfaction with care among dual eligibles enrolled in Dual Eligible Special Needs Plans (D-SNPs) versus those enrolled in Medicare Advantage (MA) plans and traditional Medicare. Findings showed that, compared with those in traditional Medicare, dual eligibles generally reported greater access to care, preventive service use, and satisfaction with care in D-SNPs. There were, however, fewer differences in these outcomes among dual eligibles in D-SNPs versus other MA plans. Overall, these findings suggested that D-SNPs altogether have not provided consistently superior or more equitable care, and they highlight areas where federal and state policy could strengthen incentives for D-SNPs to improve care.

A national assessment of legacy versus new generation Medicaid data.
The purpose of the study was to review Medicaid legacy, Medicaid new generation, and Medicare claims across multiple states and compare performance on data analytic tasks. The researchers targeted the series of events that begins with a non-hospital-related medical emergency and ends with survival to discharge or death. Six data quality indicators were developed to evaluate the following: ambulance variables; code reporting for external cause of injury; linkage between claims; and death reporting on hospital discharge status codes. For death reporting on hospital discharge status codes the researchers estimated the severity of injuries and developed a model of its correlation with death in the Medicare population. The resulting model was utilized to compare reported versus expected deaths by level of injury severity in the Medicaid population. The study found that new generation Medicare claims had high performance across states and indicators, Medicaid legacy claims underperformed on multiple indicators in most states, and while new generation Medicaid claims outperformed Medicaid legacy claims on several indicators, conducting high-level analysis with that data will require substantial improvements.

Association of dual Medicare and Medicaid eligibility with outcomes and spending for cancer surgery in high-quality hospitals.
The purpose of this study was to assess whether treatment at high-quality hospitals mitigates dual-eligibility-associated disparities in outcomes and spending for cancer surgery. Medicare beneficiaries 65 years or older who underwent colectomy, rectal resection, lung resection, or pancreatectomy were evaluated. The findings indicate that, even among the highest-quality hospitals, dual-eligibility patients had poorer outcomes and higher spending. Dually eligible patients were more likely to be discharged to a facility and thus incurred higher post-acute care costs. Although treatment at high-quality hospitals is associated with reduced differences in outcomes, dual-eligibility patients remain at high risk for adverse post-operative outcomes as well as increased readmissions and post-acute care use.

Increasing Medicaid's stagnant asset test for people eligible for Medicare and Medicaid will help vulnerable seniors.
Researchers examined states' income and asset tests for full-benefit Medicaid during the period 2006-18 and examined how alternative asset tests would affect eligibility for community-dwelling Medicare beneficiaries ages sixty-five and older. They found that increasing asset limits would lessen restrictions on Medicaid eligibility that arise from stagnant asset tests, broadening eligibility for certain low-income Medicare beneficiaries and allowing them to retain higher, yet still modest, savings.

Trends in anticoagulation prescription spending among Medicare Part D and Medicaid beneficiaries between 2014 and 2019.
Researchers examined contemporary direct oral anticoagulant (DOAC) spending patterns within Medicare Part D and Medicaid between 2014 and 2019. They found that, although overall DOAC spending is increasing, DOAC use may be associated with lower downstream medical expenditures compared with warfarin stemming from decreased risk of major bleeding and stroke and reduced drug monitoring.

Welcome mats and on-ramps for older adults: the impact of the Affordable Care Act's Medicaid Expansions on Dual Enrollment in Medicare and Medicaid.
The authors examined whether Medicaid participation by low-income adults age 65 and up increased as a result of Medicaid expansions to working-age adults under the Affordable Care Act (ACA). Using American Community Survey data and state variation in ACA Medicaid expansions, they found that Medicaid expansions to working-age adults increased Medicaid participation among low-income older adults by 4.4 percent. They also found evidence of an “on-ramp” effect, which is an important mechanism behind welcome mat effects among some older adults.

The relationship between take-up of prescription drug subsidies and Medicaid among low-income Medicare beneficiaries.
In this study, the investigators examined take-up of the Low-Income Subsidy (LIS) and Medicaid among Medicare beneficiaries who qualified for both programs. They went beyond prior analyses that reported average enrollment by program by 1.) examining whether LIS take-up mirrored Medicaid enrollment at income levels where individuals qualified for limited Medicaid benefits that had low take-up rates and 2.) highlighting opportunities for policy reforms to increase participation in both programs.

Large self-insured employers lack power to effectively negotiate hospital prices.
This study examined the ability of self-insured employers to negotiate hospital prices and investigated the relationship between hospital prices and employer market power in the United States. Findings showed that employer market power was low in most metropolitan statistical areas. Recommendations included encouraging self-insured employers to consider building purchase alliances with state and local government employee groups in order to enhance their market power and to lower negotiated prices for hospital services.

Does Medicaid coverage of Medicare cost sharing affect physician care for dual-eligible Medicare beneficiaries?
The objective of this paper was to assess changes in physicians' provision of care to duals (low-income individuals with Medicare and Medicaid) in response to a policy that required Medicaid to fully pay Medicare's cost sharing for office visits with these patients. This policy-a provision of the Affordable Care Act-effectively increased payments for office visits with duals by 0%-20%, depending on the state, in 2013 and 2014.

Modernizing Medicaid coverage for Medicare beneficiaries with low income.
Medicaid serves as a supplemental insurer for eleven million low-income Medicare beneficiaries, known as duals. For these beneficiaries, Medicaid pays for Medicare’s out-of-pocket costs, including premiums, deductibles and coinsurance. This paper examined opportunities to close these gaps in Medicaid coverage and discussed how these reforms could complement other efforts to modernize Medicaid for low-income Medicare beneficiaries.

Payment discrepancies and access to primary care physicians for dual-eligible Medicare-Medicaid beneficiaries.
This study examined whether the Affordable Care Act (ACA) primary care fee bump for dual-eligible Medicare-Medicaid beneficiaries impacted primary care physicians (PCP) acceptance of duals. The authors assessed differences in the likelihood that PCPs had dual caseloads of ≥10% or 20% in states with lower versus full dual reimbursement using linear probability models adjusted for physician and area-level traits. The proportion of PCPs with dual caseloads of ≥10% or 20% decreased significantly between 2012 and 2017. The fee bump was not consistently associated with increases in dual caseloads.

Medicaid coverage 'cliff' increases expenses and decreases care for near-poor Medicare beneficiaries.
Cost sharing in traditional Medicare can consume a substantial portion of the income of beneficiaries who do not have supplemental insurance, resulting in a supplemental coverage cliff. The authors estimated that Medicaid beneficiaries affected by this cliff incurred an additional $2,288 in out-of-pocket spending over the course of two years, used 55 percent fewer outpatient evaluation and management services per year, and filled fewer prescriptions. They recommended expanding eligibility for Medicaid supplemental coverage and increasing take-up of Part D subsidies to lessen cost-related barriers to health care among near-poor Medicare beneficiaries.

Assessment of the Patient Protection and Affordable Care Act's increase in fees for primary care and access to care for dual-eligible beneficiaries.
The purpose of this study was to examine the association between the Affordable Care Act (ACA) fee bump and primary care visits for dual-eligible Medicare and Medicaid beneficiaries. Medicare claims data from 2012 to 2016 was used. Findings showed that the ACA fee bump was not associated with increases in primary care visits for dual-eligible Medicare and Medicaid beneficiaries. Additionally, visits for dual-eligible beneficiaries with primary care physicians decreased after the ACA, a decrease that was partially offset by increases in visits with nonphysician clinicians.

Outcomes of Medicaid home- and community-based long-term services relative to nursing home care among dual eligibles.
This study measured the outcomes of dual-eligible recipients of Medicaid home- and community-based long-term services (HCBS) compared to nursing home residents. The authors used the 2005 and 2012 Medicaid Analytic eXtract (MAX) database, a national compilation of Medicaid claims which merges Medicare claims to identify hospital admissions. A cohort of 1,312,498 older adults dually enrolled in Medicaid and Medicare and using long-term care was tracked. HCBS users were found to have 10 percent points higher annual rates of hospitalization than their nursing home counterparts when selection bias is addressed. The differences persisted across races, dementia status, and intensity of HCBS spending.

New evidence of state variation in Medicaid payment policies for dual Medicare-Medicaid enrollees.
The authors developed the first longitudinal database of state Medicaid policies for paying the cost sharing in Medicare Part B for services provided to dual Medicare-Medicaid enrollees (duals), and an index summarizing the impact of these policies on payments for physician office services. Information from 2004-2018 was consolidated from online Medicaid policy documents, state laws, and policy data reported to them by state Medicaid programs. The database showed that in 2018 42 states had policies to limit Medicaid payments of Medicare cost sharing when Medicaid’s fee schedule was lower than Medicare’s. This was an increase from 36 such states in 2004. In most states, combined Medicare and Medicare payments for evaluation and management services provided to duals averaged 78% of the Medicare allowed amount for these services.

High rates of partial participation in the first year of the merit-based incentive payment system.
This article discusses concerns over the implementation of the Merit-based Incentive Payment System (MIPS) for clinicians, which was authorized with the Medicare Access and CHIP Reauthorization Act of 2015. Data was analyzed from 2017, the first implementation year of MIPS. The authors found that although 90% of participating clinicians reported performance equal to or better than the lower performance threshold of 3 out of 100, almost half of clinicians did not participate in at least one of the three program categories. Even with the low participation rate, 74% of clinicians who only partially participated in the program received positive payment adjustments. The findings underline concerns that the design may have been too flexible to effectively incentivize clinicians to make incremental progress across all targeted aspects of the program (quality, advancing care information, and improvement activities).

Differences between public and private hospital payment rates narrowed, 2012-16.
In 2000-12 payments for inpatient hospital stays, emergency department visits, and outpatient hospital care for privately insured patients grew much faster than payments for Medicare and Medicaid patients. This widening of private-public payment gaps slowed or even reversed itself in 2012-16. In this paper, the author discusses the differences between public and private hospital payment rates, 2012-2016.
