Project description:ImportanceLittle is known about how out-of-pocket burden differs between Medicare and commercial insurance for ultra-expensive drugs.ObjectiveTo investigate out-of-pocket spending for ultra-expensive drugs in the Medicare Part D program vs commercial insurance.Design, setting, and participantsThis was a retrospective, population-based cohort study of individuals using ultra-expensive drugs included in a 20% nationally random sample of prescription drug claims from Medicare Part D and individuals aged 45 to 64 years using ultra-expensive drugs included in a large national convenience sample of outpatient pharmaceutical claims from commercial insurance plans. Claims data from 2013 through 2019 were used, and data were analyzed in February 2023.Main outcomes and measuresClaims-weighted mean out-of-pocket spending per beneficiary per drug by insurance type, plan, and age.ResultsIn 2019, 37 324 and 24 159 individuals using ultra-expensive drugs were identified in the 20% Part D and commercial samples, respectively (mean [SD] age, 66.2 [11.7] years; 54.9% female). A statistically significant higher share of commercial enrollees vs Part D beneficiaries were female (61.0% vs 51.0%; P < .001), and a statistically significantly lower share were using 3 or more branded medications (28.7% vs 42.6%; P < .001). Mean out-of-pocket spending per beneficiary per drug in 2019 was $4478 in Part D (median [IQR], $4169 [$3369-$5947]) compared with $1821 for commercial (median [IQR], $1272 [$703-$1924]); these differences were statistically significant every year. Differences in out-of-pocket spending comparing commercial enrollees aged 60 to 64 years and Part D beneficiaries aged 65 to 69 years exhibited similar magnitudes and trends. By plan, mean out-of-pocket spending per beneficiary per drug in 2019 was $4301 (median [IQR], $4131 [$3000-$6048]) in Medicare Advantage prescription drug (MAPD) plans, $4575 (median [IQR], $4190 [$3305-$5799]) in stand-alone prescription drug plans (PDPs), $1208 (median [IQR], $752 [$317-$1240]) in health maintenance organization plans, $1569 (median [IQR], $838 [$481-$1472]) in preferred provider organization plans, and $4077 (median [IQR], $2882 [$1075-$4226]) in high-deductible health plans. There were no statistically significant differences between MAPD plans and stand-alone PDPs in any study year. Mean out-of-pocket spending was statistically significantly higher in MAPD plans compared with health maintenance organization plans and in stand-alone PDPs compared with preferred provider organization plans in each study year.Conclusions and relevanceThis cohort study demonstrated that the $2000 out-of-pocket cap included in the Inflation Reduction Act may substantially moderate the potential increase in spending faced by individuals who use ultra-expensive drugs when moving from commercial insurance to Part D coverage.

Project description:ImportanceMedicare beneficiaries with cancer are at risk for financial hardship given increasingly expensive cancer care and significant cost sharing by beneficiaries.ObjectivesTo measure out-of-pocket (OOP) costs incurred by Medicare beneficiaries with cancer and identify which factors and services contribute to high OOP costs.Design, setting, and participantsWe prospectively collected survey data from 18 166 community-dwelling Medicare beneficiaries, including 1409 individuals who were diagnosed with cancer during the study period, who participated in the January 1, 2002, to December 31, 2012, waves of the Health and Retirement Study, a nationally representative panel study of US residents older than 50 years. Data analysis was performed from July 1, 2014, to June 30, 2015.Main outcomes and measuresOut-of-pocket medical spending and financial burden (OOP expenditures divided by total household income).ResultsAmong the 1409 participants (median age, 73 years [interquartile range, 69-79 years]; 46.4% female and 53.6% male) diagnosed with cancer during the study period, the type of supplementary insurance was significantly associated with mean annual OOP costs incurred after a cancer diagnosis ($2116 among those insured by Medicaid, $2367 among those insured by the Veterans Health Administration, $5976 among those insured by a Medicare health maintenance organization, $5492 among those with employer-sponsored insurance, $5670 among those with Medigap insurance coverage, and $8115 among those insured by traditional fee-for-service Medicare but without supplemental insurance coverage). A new diagnosis of cancer or common chronic noncancer condition was associated with increased odds of incurring costs in the highest decile of OOP expenditures (cancer: adjusted odds ratio, 1.86; 95% CI, 1.55-2.23; P < .001; chronic noncancer condition: adjusted odds ratio, 1.82; 95% CI, 1.69-1.97; P < .001). Beneficiaries with a new cancer diagnosis and Medicare alone incurred OOP expenditures that were a mean of 23.7% of their household income; 10% of these beneficiaries incurred OOP expenditures that were 63.1% of their household income. Among the 10% of beneficiaries with cancer who incurred the highest OOP costs, hospitalization contributed to 41.6% of total OOP costs.Conclusions and relevanceMedicare beneficiaries without supplemental insurance incur significant OOP costs following a diagnosis of cancer. Costs associated with hospitalization may be a primary contributor to these high OOP costs. Medicare reform proposals that restructure the benefit design for hospital-based services and incorporate an OOP maximum may help alleviate financial burden, as can interventions that reduce hospitalization in this population.

Project description:ImportanceThe closure of the Medicare Part D coverage gap from 2010 to 2019 was intended to help decrease out-of-pocket costs for beneficiaries, especially those taking high-cost drugs. However, yearly increases in list prices and the introduction of newer and more expensive drugs may have limited savings for beneficiaries.ObjectiveTo assess the association of closure in the Medicare Part D coverage gap with projected annual out-of-pocket costs from 2010 through 2019 for rheumatoid arthritis (RA) biologics.Design, setting, and participantsThis cross-sectional analysis used data from the Medicare Formulary and Pricing Files for the first quarter (January 1 to March 31) in each calendar year from 2010 to 2019 for 17 RA biologic drug and strength combinations.ExposuresMedicare Part D plan design and drug price by year.Main outcomes and measuresExpected annual out-of-pocket costs for 1 year of treatment.ResultsAmong the 17 drug and strength combinations assessed, list prices increased each year for every product, with a mean increase of 160% for the 6 drugs available during the entire study period. For the 6 products available during the entire study period, projected mean (SD) annual out-of-pocket costs were 34% (2%) lower in 2011 than in 2010 ($6108 in 2010 to $4026 in 2011) but only 21% (8%) lower in 2019 ($4801) because of yearly increases in list price. All 4 products with higher out-of-pocket costs in 2019 than in the first year available entered the market between 2011 and 2015. For all products studied, the percentage of money spent in the catastrophic phase increased each year and was a mean (SD) of 22% (14%) higher in 2019 than in 2010 or the year first available.Conclusions and relevanceAlthough beneficiaries experienced large reductions in out-of-pocket spending from 2010 to 2011, more than half of those savings were lost by 2019 because of annual increases in list prices, even as the coverage gap continued to close in subsequent years.

Project description:ObjectivesTo examine the association between statin out-of-pocket (OOP) costs and utilization among the Medicare Part D population.Data sources/study setting2006-2008 administrative claims and enrollment data for the 5 percent Medicare sample.Study designSample included 346,583 beneficiary-year observations of statin users enrolled in stand-alone prescription drug plans, excluding low-income subsidy recipients. We estimated the association between a plan's OOP statin costs and statin utilization using an instrumental variable approach to account for potential bias due to plan selection. Adherence was defined as percentage of days covered (PDC) of at least 80 percent. Plan OOP costs were constructed for a representative market basket of statin medications. Analyses controlled for demographic characteristics, cardiovascular disease risk, co-morbidity presence, and regional characteristics.Principal findingsAbout 67 percent of the sample had a PDC of at least 80 percent. An increase in annual statin OOP from $200 (50th percentile) to $240 (75th percentile) was associated with a reduction in the rate of adherent beneficiaries from 67 percent to 56 percent (p < .001).ConclusionsGreater OOP costs for statins are associated with reductions in statin utilization.

Project description:BACKGROUND:Little is known about the impact of different types of chronic diseases on older adults' out-of-pocket healthcare spending and whether certain diseases trigger higher spending needs than others. METHODS:We use data from the 2014 Health and Retirement Study representing a weighted population of 35,939,270 Medicare beneficiaries aged 65+. Generalized linear models are applied to estimate the effect of different chronic diseases on total out-of-pocket expenditure, adjusted for demographics, socio-economic status, physical health, and other factors. We also decompose total spending by expenditure categories (inpatient, non-inpatient, and prescription drug spending). Sensitivity analysis is performed using a younger sample of older adults aged 50-64. RESULTS:Cardiovascular disease, diabetes, hypertension and cancer, induce significantly higher adjusted out-of-pocket spending among older adults than other conditions. These results hold regardless how the spending differences are assessed (absolute or percentage terms). For Medicare beneficiaries, cardiovascular disease is associated with an excess out-of-pocket spending of $317 per year, followed by diabetes ($237), hypertension ($150), and cancer ($144). Prescription drug spending is singularly the most important driver of additional expenses for cardiovascular disease, diabetes and hypertension, while non-inpatient services spending accounts for the bulk of increased spending among those with cancer. CONCLUSIONS:Our finding that major noncommunicable diseases impact individuals' out-of-pocket medical spending differentially-and that service drivers of increased spending may be heterogeneous across disease types-suggest that health professionals and policymakers should recognize that certain chronic diseases exert greater financial toll on the elderly. Interventions to promote more cost efficient healthcare services and consumer choices can help older adults better cope with these expensive long-lasting conditions and reduce the overall burden of noncommunicable diseases.

Project description:Inpatient and skilled nursing facility (SNF) cost sharing in Medicare Advantage (MA) plans may reduce unnecessary use of these services. However, large out-of-pocket expenses potentially limit access to care and encourage beneficiaries at high risk of needing inpatient and postacute care to avoid or leave MA plans. In 2011 new federal regulations restricted inpatient and skilled nursing facility cost sharing and mandated limits on out-of-pocket spending in MA plans. After these regulations, MA members in plans with low premiums averaged $1,758 in expected out-of-pocket spending for an episode of seven hospital days and twenty skilled nursing facility days. Among members with the same low-premium plan in 2010 and 2011, 36 percent of members belonged to plans that added an out-of-pocket spending limit in 2011. However, these members also had a $293 increase in average cost sharing for an inpatient and skilled nursing facility episode, possibly to offset plans' expenses in financing out-of-pocket limits. Some MA beneficiaries may still have difficulty affording acute and postacute care despite greater regulation of cost sharing.

Project description:ImportancePrior research has documented the increase in prescription drug rebates and the coincident increase in out-of-pocket burden for patients paying coinsurance tied to list prices.ObjectiveTo describe the out-of-pocket burden on patients with coinsurance and assess its association with pharmaceutical competition, which increases payers' leverage to seek higher rebates.Design, setting, and participantsThis retrospective cohort study used branded prescription drugs with US sales reported by publicly traded companies. The study included drugs with nonmissing, nonnegative rebates between 2014 and 2018 from SSR Health. Data analysis was conducted from June to December 2020.ExposuresLevel of branded and generic competition and calendar year.Main outcomes and measuresRetail price markup (ie, the ratio of rebate to net price) paid by patients at the point of sale and effective out-of-pocket share (ie, coinsurance multiplied by list price divided by net price) of a standard Part D plan. Trends in these outcomes were examined and then stratified by degree of competition.ResultsThere were 3322 unique National Drug Codes in the analysis, representing 232 distinct molecules from 138 therapeutic classes in 34 disease areas. The ratio of rebate to net prices was higher and increased faster for drugs with branded and generic competitors (from 83% to 172%) than for drugs with only branded competitors (from 61% to 115%) and those without generic equivalents (from 33% to 49%). Hypothetical patients paying standard Part D coinsurance on drug list prices would have experienced an effective out-of-pocket share increase from 48% to 64% in the initial coverage phase, and from 10% to 13% in the catastrophic coverage phase between 2014 and 2018. In the coverage gap, the share increased from 92% in 2014 to 98% in 2016 and then decreased to 90% in 2018. Compared with drugs with no competition, effective out-of-pocket share paid by patients grew 50% faster for drugs with branded competitors and 100% faster for those with branded and generic competitors.Conclusions and relevanceThis study found substantial increases in cost-sharing burden for patients paying coinsurance on drug list prices between 2014 and 2018, especially in markets with more pharmaceutical competition. Payers passing rebates through to patients at the point of sale could restore the benefits of competition and rebates.

Project description:OBJECTIVE:To update a past systematic review on whether Medicare Part D changed drug utilization and out-of-pocket (OOP) costs overall and within subpopulations, and to identify evidence gaps. DATA SOURCES/STUDY SETTING:Published and gray literature from 2010 to 2015 meeting prespecified screening criteria, including having a comparison group, and utilization or OOP cost outcomes. STUDY DESIGN:We conducted a systematic literature review with a quality assessment. DATA COLLECTION/EXTRACTION METHODS:For each study, we extracted information on study design, data sources, analytic methods, outcomes, and limitations. Because outcome measures vary across studies, we did a qualitative synthesis rather than meta-analysis. PRINCIPAL FINDINGS:Sixty-five studies met screening criteria. Overall, Medicare Part D enrollees have increased drug utilization and decreased OOP costs, but coverage gaps limit the program's impact. Beneficiaries whose insurance becomes more generous after enrollment had disproportionately increased drug utilization and decreased OOP costs. Outcomes among dual-eligibles were mixed. CONCLUSIONS:There is strong evidence on how Medicare Part D and the donut hole coverage gap affect utilization and OOP costs, but weak evidence on how effects vary among dual-eligibles or across diseases. Findings suggest that the Affordable Care Act's provisions to expand coverage and reduce the donut hole should improve patient outcomes.

Project description:Medicare Part D has no cap on beneficiaries' out-of-pocket spending for outpatient prescription drugs, and, unlike Medicare Parts A and B, beneficiaries are prohibited from purchasing supplemental insurance that could provide such a cap. Historically, most beneficiaries whose annual Part D spending reached the catastrophic level were protected from unlimited personal liability by the Low-Income Subsidy (LIS). However, we found that the proportion of beneficiaries whose spending reached that level but did not qualify for the subsidy-and therefore remained liable for coinsurance-increased rapidly, from 18 percent in 2007 to 28 percent in 2015. Moreover, average total per person per year spending grew much more rapidly for those who did not qualify for the LIS than for those who did, primarily because of differences in price and utilization trends for the drugs that represented disproportionately large shares of their spending. We estimated that a cap for all Part D enrollees in 2015 would have raised monthly premiums by only $0.40-$1.31 per member.

Project description:BackgroundSources of regional variation in spending for prescription drugs under Medicare Part D are poorly understood, and such variation may reflect differences in health status, use of effective treatments, or selection of branded drugs over lower-cost generics.MethodsWe analyzed 2008 Medicare data for 4.7 million beneficiaries for prescription-drug use and expenditures overall and in three drug categories: angiotensin-converting-enzyme (ACE) inhibitors and angiotensin-receptor blockers (ARBs), 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors (statins), and selective serotonin-reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs). Differences in per capita expenditures across hospital-referral regions (HRRs) were decomposed into annual prescription volume and cost per prescription. The ratio of prescriptions filled as branded drugs to all prescriptions filled was calculated. We adjusted all measures for demographic, socioeconomic, and health-status differences.ResultsMean adjusted per capita pharmaceutical spending ranged from $2,413 in the lowest to $3,008 in the highest quintile of HRRs. Most (75.9%) of that difference was attributable to the cost per prescription ($53 vs. $63). Regional differences in cost per prescription explained 87.5% of expenditure variation for ACE inhibitors and ARBs and 56.3% for statins but only 36.1% for SSRIs and SNRIs. The ratio of branded-drug to total prescriptions, which correlated highly with cost per prescription, ranged across HRRs from 0.24 to 0.45 overall and from 0.24 to 0.55 for ACE inhibitors and ARBs, 0.29 to 0.60 for statins, and 0.15 to 0.51 for SSRIs and SNRIs.ConclusionsRegional variation in Medicare Part D spending results largely from differences in the cost of drugs selected rather than prescription volume. A reduction in branded-drug use in some regions through modification of Part D plan benefits might lower costs without reducing quality of care.
