Insurance coverage for obesity treatment.

Recent work demonstrates the benefits of weight loss from intensive lifestyle modification. One barrier to counseling may be lack of reimbursement. We sought to quantify the obesity coverage policies of insurers in Pennsylvania. A three-page questionnaire was sent to eligible Pennsylvania health plans. Respondents included company medical directors and administrators from other departments, including public relations, provider relations, disease management, and utilization review. The questionnaire inquired about major treatment modalities for obesity, including details of coverage. Sixteen of 19 eligible plans (84%) responded. All plans provided some coverage for bariatric surgery. Nine out of 16 companies (56%) stated that they covered individual dietary counseling, but only five paid for intensive counseling. Less than 50% of plans reimbursed other forms of lifestyle modification or weight loss medication. Surgery was covered significantly more often than all other treatment modalities (P<0.02 for all comparisons). No differences in reimbursement were found by plan type or by number of enrollees. Insurance reimbursement for obesity in Pennsylvania does not consistently reflect recent evidence for the benefits of lifestyle modification. Given the increasing evidence for the clinical and cost-effectiveness of nonsurgical weight loss therapy, coverage policies may begin to change.

SCHIP expansion and parental coverage: an evaluation of Wisconsin's BadgerCare.

The Wisconsin BadgerCare program, which became operational in July 1999, expanded public health insurance eligibility to both parents and children in families with incomes below 185% of the U.S. poverty line (200% for those already enrolled). This eligibility expansion was part of a federal initiative known as the State Children's Health Insurance Program (SCHIP). Wisconsin was one of only four states that initially expanded coverage to parents of eligible children. In this paper, we attempt to answer the following question: To what extent does a public program with the characteristics of Wisconsin's BadgerCare program reduce the proportion of the low-income adult population without health care coverage? Using a coordinated set of administrative databases, we track three cohorts of mother-only families: those who were receiving cash assistance under the Wisconsin AFDC and TANF programs in September 1995, 1997, and 1999, and who subsequently left welfare. We follow these 19,201 "welfare leaver" families on a quarterly basis for up to 25 quarters, from 2 years before they left welfare through the end of 2001, making it possible to use the labor market information and welfare history of the women in analyzing outcomes. We apply multiple methods to address the policy evaluation question, including probit, random effects, and two difference-in-difference strategies, and compare the results across methods. All of our estimates indicate that BadgerCare substantially increased public health care coverage for mother-only families leaving welfare. Our best estimate is that BadgerCare increased the public health care coverage of all adult leavers by about 17-25% points.

Premium subsidies for health insurance: excessive coverage vs. adverse selection.

The tax subsidy for employment-related health insurance can lead to excessive coverage and excessive spending on medical care. Yet, the potential also exists for adverse selection to result in the opposite problem-insufficient coverage and underconsumption of medical care. This paper uses the model of Rothschild and Stiglitz (R-S) to show that a simple linear premium subsidy can correct market failure due to adverse selection. The optimal linear subsidy balances welfare losses from excessive coverage against welfare gains from reduced adverse selection. Indeed, a capped premium subsidy may mitigate adverse selection without creating incentives for excessive coverage.

Adolescents' knowledge of their health insurance coverage.

PURPOSE: To determine the accuracy of adolescents' self-report of health insurance coverage, using parents' report as a comparison standard. METHODS: Two separate samples of urban, school-based adolescents and their parents completed self-administered questionnaires about type of health insurance coverage. Sample 1 included 123 and Sample 2 included 93 adolescent-parent pairs. Percent agreement and the kappa statistic were determined for each of the sample groups, and for males versus females and older (> 14 years) versus younger (< or = 14 years) adolescents. RESULTS: In Sample 1, 33% of adolescent respondents responded "don't know" to the question about type of insurance coverage, and 4% left the question blank; in Sample 2, 3% answered "don't know," with none leaving the question blank. For Sample 1, we found a 57% rate of agreement of adolescents with their parents, and a corresponding kappa of .21. Females and older subjects demonstrated greater accuracy, with kappa's all in the range .13-.29. In Sample 2, 73% of subjects agreed with parents' report, with a kappa of .48. Females and older subjects also demonstrated greater accuracy, with the highest kappa of .59 demonstrated by older females. Excluding those responding with "don't know," we found overall percent agreement with parents of 87% in Sample 1 and 73% in Sample 2; the corresponding kappas were .47 and .51. Females demonstrated higher agreement with parents in both samples. The results stratifying by age were inconsistent. In Sample 1, privately insured subjects were more accurate reporters than those either on medical assistance or uninsured. In Sample 2, no differences were seen by type of insurance. CONCLUSIONS: Many adolescents do not know their health insurance coverage status. However, for those who did claim to know, acceptable rates of accuracy using both percent agreement and the kappa statistic were demonstrated. Further research is needed to determine how information about insurance is communicated to adolescents and how this knowledge affects access to and use of health services.

Inadequate prescription-drug coverage for Medicare enrollees--a call to action.

In summary, most low-income elderly and disabled persons lack coverage for important medications, resulting in avoidable deterioration of health among those with chronic illnesses and use of expensive institutional services. Rapidly escalating drug costs, more restrictive drug-coverage policies, and a dramatic increase in the population of elderly and disabled persons will exacerbate these problems. With the current budget surplus, as well as bipartisan concern about health care needs and public concern about drug costs and coverage, it is time to act responsibly and aggressively. We recommend a national replication of the best features of state pharmacy-assistance programs in a federal-state insurance program for low-income Medicare enrollees, either alone or in combination with expanded Medicare coverage. Such a program will reduce the current inequitable situation in which the most vulnerable patients have the least access to medications, with serious medical and economic consequences.

The national coverage decision for reimbursement for biofeedback and pelvic floor electrical stimulation for treatment of urinary incontinence.

On October 6, 2000, the Centers for Medicare & Medicaid Services (CMS) (formerly the Health Care Financing Administration) issued a national coverage decision for the use of biofeedback and pelvic floor electrical stimulation in the treatment of urinary incontinence. This decision was the first major health care coverage decision made using CMS's new "open" process. The new process included the use of a panel of physicians to evaluate adequacy of evidence to support the utilization of the modalities. From the very beginning, there were indications that CMS was not favorably disposed toward the use of these modalities, and there was a real threat that coverage could be withdrawn or that no decision would be made. The organized and cohesive response of the health care community influenced CMS to make a positive coverage decision. Through the diligent and tenacious work of a group of nurses called the SUNA/WOCN Continence Coalition, professional organizations and prominent individuals were brought together to approach CMS with one message and one voice.

Association between health insurance coverage of office visit and cancer screening among women.

BACKGROUND: Little is known regarding the nuances of insurance benefit design that may affect the receipt of clinical preventive services. OBJECTIVE: To evaluate whether differences in insurance coverage of physician office visits influences the receipt of cancer screening in women who have full coverage for the screening services. DESIGN: Cohort study of women enrolled in fee-for-service (FFS) or Preferred Provider Organization (PPO) health plans, where FFS plans have less generous office visit coverage, for the period 1995 to 1997. SETTINGS AND PARTICIPANTS: General Motors Corporation's employees and their dependents. MAIN OUTCOME MEASURES: Papanicolaou and mammography rates in women aged 21 to 64 years (n = 139,294) and 52 to 64 years (n = 56,554), respectively. RESULTS: Compared with FFS plans, enrollees in PPO plans were significantly more likely to obtain a Papanicolaou smear and mammogram (adjusted relative risk [RRa] = 1.22; 95% CI, 1.21-1.24; and RRa, 1.17; 95% CI, 1.15-1.18, respectively). The association was more pronounced among hourly individuals (RRa, 1.27; 95% CI, 1.26-1.29 for Papanicolaou smears; RRa, 1.17; 95% CI, 1.16-1.19 for mammograms) than among salaried individuals (RRa, 1.10; 95% CI, 1.08-1.12 for Papanicolaou smears and RRa, 1.10; 95% CI, 1.06-1.12 for mammograms), corresponding to a greater differential in office visit coverage among the hourly group. CONCLUSIONS: Benefit structure appears to have an important effect on receipt of cancer screening in women. The findings highlight the need to ensure that future reforms of the health care system do not adversely affect the use of preventive services.

Assessing the validity of insurance coverage data in hospital discharge records: California OSHPD data.

OBJECTIVE: To assess the accuracy of data on "expected source of payment" in the patient discharge database compiled by the California Office of Statewide Health Planning and Development (OSHPD). DATA SOURCES: The OSHPD discharge data for the years 1993 to 1996 linked with administrative data from the University of California (UC) health benefits program for the same years. The linked dataset contains records for all stays in California hospitals by UC employees, retirees, and spouses. STUDY DESIGN: The accuracy of the OSHPD data is assessed using cross-tabulations of insurance type as coded in the two data sources. The UC administrative data is assumed to be accurate, implying that differences between the two sources represent measurement error in the OSHPD data. We cross-tabulate insurance categories and analyze the concordance of dichotomous measures of health maintenance organization (HMO) enrollment derived from the two sources. PRINCIPAL FINDINGS: There are significant coding errors in the OSHPD data on expected source of payment. A nontrivial percentage of patients with preferred provider organization (PPO) coverage are erroneously coded as being in HMOs, and vice versa. The prevalence of such errors increased after OSHPD introduced a new expected source of payment category for PPOs. Measurement problems are especially pronounced for older patients. Many patients over age 65 who are still covered by a commercial insurance plan are erroneously coded as having Medicare coverage. This, combined with the fact that during the period we analyzed, Medicare HMO enrollees and beneficiaries in the fee-for-service (FFS) program are combined in a single payment category, means that the OSHPD data provides essentially no information on insurance coverage for older patients. CONCLUSIONS: Researchers should exercise caution in using the expected source of payment in the OSHPD data. While measures of HMO coverage are reasonably accurate, it is not possible in these data to clearly identify PPOs as a distinct insurance category. For patients over age 65, it is not possible at all to distinguish among alternative insurance arrangements.

The case for a medicare drug coverage benefit: a critical review of the empirical evidence.

The lack of an outpatient prescription drug benefit under Medicare has become a conspicuous omission in the face of accelerated growth in prescription drug expenditures and increased availability of highly effective medications. This article provides a critical review of the empirical evidence on the effect of drug coverage on the use of prescription drugs, health care outcomes, and health care costs among Medicare beneficiaries. The existing literature provides considerable evidence that drug coverage is associated with greater use of all drugs and clinically essential medications and that not all forms of coverage provide the same protection. Longitudinal evidence from elderly and disabled persons in Medicaid indicates that restricting coverage has serious adverse health outcomes for sick and low-income beneficiaries that actually lead to increased health care costs.

Changes in insurance coverage and extent of care during the two years after first hospitalization for a psychotic disorder.

OBJECTIVE: This study examined changes in insurance coverage during the 24 months after first admission for a psychotic disorder and the relationship of insurance type to the extent of care. METHODS: The sample consisted of 443 persons who were enrolled in the Suffolk County (New York) Mental Health Project. Information about coverage-private insurance, Medicaid-Medicare, or no insurance-was obtained from hospital records and interviews. The insurance status groups were compared to examine differences in the percentage of days they received inpatient, outpatient, and day hospital care. RESULTS AND CONCLUSIONS: The proportion of persons with no insurance decreased from baseline to 24 months, from 42 percent to 21 percent. The proportion of persons with private insurance remained similar, 42 and 37 percent. The proportion of those with Medicaid-Medicare increased from 15 percent to 42 percent. Of those with Medicaid-Medicare at baseline (67 persons), 88 percent had such coverage 24 months later. Of those with private insurance at baseline (188 persons), 73 percent had the same coverage 24 months later. Of those with no insurance at baseline (188 persons), 35 percent had no insurance at 24 months, 54 percent had Medicaid-Medicare, and 11 percent had private insurance. Over the 24 months, the Medicaid-Medicare group had the most days of care, the private insurance group had the least inpatient care, and those with no insurance were least likely to receive outpatient care. There was a linear relationship between receiving more outpatient care and spending less time in the hospital and the day hospital.

Patterns of health insurance coverage among rural and urban children.

Despite the potential for the State Children's Health Insurance Program to improve the health care coverage of rural children, the expansion of public health insurance to children in rural areas may be hampered by a lack of understanding about the patterns of insurance coverage they experience. This study uses the Census Bureau's 1993-1996 panel of the Survey of Income and Program Participation to evaluate differences in the duration of, and in their entry into and exit from, uninsured spells. While the average duration of new spells was shorter for rural children and most regained coverage quickly, rural children were also more likely than urban children to experience protracted spells of uninsurance. Moreover, rural children were more likely than urban children to move between public and private coverage. These findings have important implications for designing insurance expansion programs and outreach strategies to effectively enroll and retain rural children.

Global disparities in COVID-19 vaccine coverage associated with trajectories of SARS-CoV-2 adaptation.

BACKGROUND: Vaccination serves as an effective intervention for health promotion and disease prevention across the socioecological systems and has played an important role during the COVID-19 pandemic. However, global disparities in vaccine coverage have increased uncertainty about the trajectories of viral adaptation, and the potential interplay between SARS-CoV-2 adaptation and vaccine rollout warrants further quantification. METHODS: Using over 13&#xa0;million SARS-CoV-2 genomes across 86 countries from March 2020 to September 2022, we analyzed nonlinear associations between SARS-CoV-2 adaptation and vaccination coverage, considering public health and social measures, international travel, and infection dynamics, before and after the emergence of Omicron. Additionally, we examined the relationship between SARS-CoV-2 adaptation and COVID-19 mortality. RESULTS: During the pre-Omicron period, we found positive associations between nonsynonymous to synonymous divergence (dN/dS) ratios in the S1 subunit and medium levels of adjusted vaccine coverage (effect size: 0.96 [95% CI 0.47, 1.45]), while the association became insignificant at high levels (effect size: -1.89 [95% CI -4.20, 0.43]). However, no significant associations were found when Omicron dominated, possibly due to the immune escape ability of Omicron variants and the complex immune landscape shaped by mass hybrid immunity. Moreover, we observed evidence of dynamic interdependence and positive correlations between COVID-19 mortality and SARS-CoV-2 adaptation, with COVID-19 mortality interpreted as a proxy for uncontrolled viral spread. CONCLUSIONS: Our findings suggest a complex nonlinear relationship between vaccine-induced immunity and SARS-CoV-2 adaptation, with high vaccine coverage potentially linked to lower positive selection. We also observed directional coupling between COVID-19 mortality and SARS-CoV-2 adaptation. This may have implications for fair and fast vaccination in pandemic preparedness and response. CLINICAL TRIAL NUMBER: Not applicable.

Using clinical trials as a condition of coverage: lessons from the National Emphysema Treatment Trial.

In making evidence-based coverage decisions, The Centers for Medicare & Medicaid Services (CMS) often must balance the need for rigorous evaluation of medical technologies with the public's demand for rapid access to new services. During the mid-1990s, this dilemma was apparent with regard to a promising, yet unproven, new procedure for emphysema patients known as lung volume reduction surgery (LVRS). In a unique decision, CMS provided coverage for LVRS only under the protocol of the National Emphysema Treatment Trial (NETT), which it cosponsored with the National Heart, Lung, and Blood Institute. The CMS has recently revised its coverage policy for LVRS based on the results of the NETT. This paper provides a history and rationale for CMS's approach to paying for LVRS. It also discusses lessons learned from the NETT experience and potential implications for future collaborations between health plans and the clinical research enterprise that would provide better information for coverage treatment decisions.

Inclusion of immigrant families in U.S. health coverage expansions.

This paper examines federal and state restrictions on immigrants and the negative impact of these restrictions on local efforts to serve the uninsured. It examines a health coverage program offered to low-income residents in Alameda County, California from 2000 to 2005, illustrating local efforts to expand health coverage to both adults and children, regardless of immigration status. After five years of operating the pilot program, leaders of Alameda County's health care safety net conclude that local health coverage programs are unsustainable over a long period of time without significant federal and state support. The financial resources that federal, state, and local governments are patching together for health coverage could be used more efficiently if consolidated. Stabilizing the federal tax base and recognizing the phenomenal amount of federal, state, and local funding that is already spent on medical care for the uninsured are the first steps towards achieving meaningful health care reform.

Gaps in health coverage among working-age Americans and the consequences.

This paper examines health coverage and access to care among working-age adults using the Kaiser/Commonwealth 1997 National Survey of Health Insurance. One in three (52 million) working-age adults were either uninsured at the time of the survey or had a recent gap in their health coverage in the past two years. Having even a temporary gap in health coverage made a significant difference in access to care. Compared to the elderly, who are continuously covered by Medicare, working-age adults have greater problems paying their medical bills and gaining access to care and are less satisfied with their health insurance coverage.

Health care for children and youth in the United States: annual report on patterns of coverage, utilization, quality, and expenditures by income.

OBJECTIVES: To examine differences by income in insurance coverage, health care utilization, expenditures, and quality of care for children in the United States. METHODS: Two national health care databases serve as the sources of data for this report: the 2000-2002 Medical Expenditure Panel Survey (MEPS) and the 2001 Nationwide Inpatient Sample (NIS) from the Healthcare Cost and Utilization Project (HCUP). In the MEPS analyses, low income is defined as less than 200% of the federal poverty level and higher income is defined as 200% of the federal poverty level or more. For the HCUP analyses, median household income for the patient's zip code of residence is used to assign community-level income to individual hospitalizations. RESULTS: Coverage. Children from low-income families were more likely than children from middle-high-income families to be uninsured (13.0% vs 5.8%) or covered by public insurance (50.8% vs 7.3%), and less likely to be privately insured (36.2% vs 87.0%). Utilization. Children from low-income families were less likely to have had a medical office visit or a dental visit than children from middle-high-income families (63.7% vs 76.5% for office-based visits and 28.8% vs 51.4% for dental visits) and less likely to have medicines prescribed (45.1% vs 56.4%) or have utilized hospital outpatient services (5.2% vs 7.0%), but more likely to have made trips to the emergency department (14.6% vs 11.4%). Although low-income children comprise almost 40% of the child population, one quarter of total medical expenditures were for these children. Hospital Discharges. Significant differences by community-level income occurred in specific characteristics of hospitalizations, including admissions through the emergency department, expected payer, mean total charges per day, and reasons for hospital admission. Leading reasons for admission varied by income within and across age groups. Quality. Low-income children were more likely than middle-high-income children to have their parents report a big problem getting necessary care (2.4% vs 1.0%) and getting a referral to a specialist (11.5% vs 5.3%). Low-income children were at least twice as likely as middle-high-income children to have their parents report that health providers never/sometimes listened carefully to them (10.0% vs 5.1%), explained things clearly to the parents (9.6% vs 3.4%), and showed respect for what the parents had to say (9.2% vs 4.2%). Children from families with lower community-level incomes were more likely to experience ambulatory-sensitive hospitalizations. Racial/Ethnic Differences Between Income Groups. Use and expenditure patterns for most services were not significantly different between low- and middle-high-income black children and were lower than those for white children. CONCLUSIONS: While health insurance coverage is still an important factor in obtaining health care, the data suggest that efforts beyond coverage may be needed to improve access and quality for low-income children overall and for children who are racial and ethnic minorities, regardless of income.

Drug coverage decisions: the role of dollars and values.

Given the increasing costs of pharmaceuticals today, it is important to understand how pharmacy benefits decisions are made and the role of cost and values in these decisions. This study examines what coverage decisions insurers make and the information and processes used in making these decisions. Fifty-three organizations, differing in size, tax status, and region, were asked about their policies for four new and controversial drugs: Viagra, Enbrel, Zyban, and Celebrex. Enbrel and Celebrex were much more likely to be covered than Viagra and Zyban. In addition, coverage of Enbrel and Celebrex was limited through strategies such as prior authorization, to encourage medically appropriate use of these agents, whereas coverage of Viagra and Zyban was limited predominantly through generalized exclusion or through restrictions on quantity or duration of use. Value judgments, rather than cost, seem to play a central, though largely unspoken, role in these coverage decisions.

Socioeconomic differences in Medicare supplemental coverage.

In this study we compare the beneficiaries with various types of Medicare supplemental insurance coverage to examine the impact of socioeconomic characteristics on such coverage. We found that those who are more disadvantaged are less likely to have any coverage, and those who have it are less likely to have it subsidized by a former employer. These findings have direct implications for the fairness of proposed programs to provide prescription drug coverage to Medicare beneficiaries, and for the advisability of various proposals for reforming Medicare, including "premium-support" programs.
