Disparities in Enrollment in Medicare Advantage Plans With Dental Benefits.

This cross-sectional study evaluates the association of Medicare beneficiaries' sociodemographic characteristics with having Medicare Advantage plans that cover oral health services.

Claims analysis of Medicare fee-for-service oral health care encounters, from 2019 through 2021.

BACKGROUND: Many qualifying people rely on Medicare fee-for-service (FFS) for their health care insurance, although it rarely provides coverage for oral health care services. The objective of this study was to gain insights into oral health care that is being provided by all health care provider types for Medicare FFS beneficiaries. METHODS: The authors used the Centers for Medicare & Medicaid Services Virtual Data Research Center to query 100% of Medicare FFS claims from 2019 through 2021 and identify all encounters for which there was either an oral health-related International Classification of Diseases, Tenth Revision, Clinical Modification diagnosis code or a CDT 2019-2021: Current Dental Terminology code recorded on the claim. The authors used a cross-sectional study design and calculated descriptive statistics to describe characteristics of identified oral health care encounters. The encounter level was the unit of analysis. RESULTS: A total of 2,098,056 oral health care encounters were identified through Medicare FFS claims during the study observation period, with a lower volume observed after 2019. Nearly 98% of encounters were related to those in which oral health diagnoses were recorded (International Classification of Diseases, Tenth Revision, Clinical Modification code on claim), and non-oral health care providers primarily submitted these claims. Most encounters included beneficiaries with chronic conditions, and a roughly equal proportion included those qualifying for Medicare on the basis of age and disability. CONCLUSIONS: Previously unreported characteristics of oral health care encounters were identified through administrative claims, providing insights into oral health care being provided to a subset of Medicare FFS beneficiaries. PRACTICAL IMPLICATIONS: Future research and policies should focus on strengthening medical-dental integration models and expanding access to oral health care for the Medicare FFS population.

Association Between Medicaid Dental Payment Policies and Children's Dental Visits, Oral Health, and School Absences.

Importance: Although all state Medicaid programs cover children's dental services, less than half of publicly insured children receive recommended care. Objective: To evaluate the association between the ratio of Medicaid payment rates to dentist charges for an index of services (fee ratio) and children's preventive dental visits, oral health, and school absences. Design, Setting, and Participants: In this cross-sectional study, a difference-in-differences analysis was conducted between September 2021 and April 2022 of 15 738 Medicaid-enrolled children and a control group of 16 867 privately insured children aged 6 to 17 years who participated in the 2016-2019 National Survey of Children's Health. Exploratory subgroup analyses by sex and race and ethnicity were also performed. A 2-sided P < .05 was considered significant. Main Outcomes and Measures: Past-year preventive dental visits (at least 1 and at least 2), parent-reported excellent oral health, and number of days absent from school (at least 4 days and at least 7 days). Results: The Medicaid-enrolled sample included a weighted estimate of 51.20% boys and 48.80% girls (mean age, 11.24 years; Black, 21.65%; Hispanic, 37.75%; White, 31.45%). By weighted baseline estimates, 87% and 48% of Medicaid-enrolled children had at least 1 and at least 2 past-year dental visits, respectively, and 29% had parent-reported excellent oral health. Increasing the fee ratio by 1 percentage point was associated with percentage point increases of 0.18 in at least 1 dental visit (95% CI, 0.07-0.30), 0.27 in at least 2 visits (95% CI, 0.04-0.51), and 0.19 in excellent oral health (95% CI, 0.01-0.36). Increases in at least 2 visits were larger for Hispanic children than for White children. By weighted baseline estimates, 28% and 15% of Medicaid-enrolled children had at least 4 and at least 7 past-year school absences, respectively. Regression estimates for school absences were not statistically significant for the full sample but were estimated to be significantly reduced among girls. Conclusions and Relevance: This cross-sectional study found that more generous Medicaid payment policies were associated with significant but modest increases in children's preventive dental visits and excellent oral health. Further research is needed to understand the potential association between policies that improve access to dental care and children's academic success.

The Association Between Medicaid Adult Dental Coverage And Children's Oral Health.

Although all state Medicaid programs cover children's dental care, Medicaid-eligible children are more likely to experience tooth decay than children in higher-income families. Using data from the 1999-2016 National Health and Nutrition Examination Survey and the 2003, 2007, and 2011-12 waves of the National Survey of Children's Health, we examined the association between Medicaid adult dental coverage (an optional benefit) and children's oral health. Adult dental coverage was associated with a statistically significant 5-percentage-point reduction in the prevalence of untreated caries among children after Medicaid-enrolled adults had access to coverage for at least one year. These policies were also associated with a reduction in parent-reported fair or poor child oral health with a two-year lag between the onset of the policy and the effect. Effects were concentrated among children younger than age twelve. We estimated declines in poor oral health among all racial and ethnic subgroups, although there was some evidence that non-Hispanic Black children experienced larger and more persistent effects than non-Hispanic White children. Future assessments of the costs and benefits of offering adult dental coverage may consider potential effects on the children of adult Medicaid enrollees.

Enrollment trends in employer-sponsored health plans that include dental benefits.

BACKGROUND: In this study, the authors provide a better understanding of enrollment trends associated with dental plans embedded in private-sector, employer-sponsored insurance health plans for the years 2005, 2010, 2015, and 2018. METHODS: Data used were from the insurance component of the Medical Expenditure Panel Survey. The authors present the number of employees enrolled in employer-sponsored insurance health plans and the percentage of these employees enrolled in health plans that include dental benefits. The authors present yearly estimates for 2005, 2010, 2015, and 2018, according to employer characteristics and state. RESULTS: While the number of embedded dental benefit plans has decreased from approximately 14.1 million plans to slightly more than 9.3 million plans in 2018 since 2005, the percentage of enrollees in employer-sponsored insurance health plans with dental coverage has decreased from approximately 23.2% of enrollees to slightly more than 15.0%. CONCLUSIONS: Although the percentage of embedded dental plans is decreasing, they are still an important component of the dental insurance market and are especially important to those employees who are enrolled. PRACTICAL IMPLICATIONS: Information will provide a better understanding of the source and extent of embedded dental plans provided via private-sector employers. These plans are often less generous than stand-alone plans.

Does covering routine dental care for the Medicare population produce cost savings in Medicare? A preliminary 2-year analysis.

OBJECTIVES: We estimated the association between the use of preventive dental care and medical use and expense for older persons over a 2-year period to determine if a Medicare dental benefit for routine care could result in potential cost savings in Medicare. METHODS: We relied on 2008-2014 Medical Expenditure Panel Survey data to estimate separate logistic and lognormal ordinary least squares regressions to analyze the influence of year 1 preventive dental care on either year 1 or year 2 use and expenses for total health care, office-based care, outpatient care, inpatient stays, emergency department visits, and prescription drugs. RESULTS: Our findings provide evidence over a 2-year period that a Medicare dental benefit for routine care could produce an increase in office-based visits and expense. We also found that older persons currently using routine dental care have healthier lifestyles and greater access to care and use of preventive medical care than current nonusers. CONCLUSION: Our results affirm the need for a longer-term study to provide any conclusive evidence as to the ultimate impact of a Medicare dental benefit on other health care use and expenses.

The demand for preventive and restorative dental services among older adults.

Many older Americans have poor access to dental care, resulting in a high prevalence of oral health problems. Because traditional Medicare does not include dental care benefits, only older Americans who are employed, have post-retirement dental benefits or spousal coverage, or enroll in certain Medicare Advantage plans are able to obtain dental care coverage. We seek to determine the extent to which poor access to dental insurance and high out-of-pocket costs affect dental service use by the elderly. Using the 2007-2015 Medical Expenditure Panel Survey and supplemental data on dental care prices, we estimate a demand system for preventive dental services and basic and major restorative services. Selection into dental and medical insurance is addressed using a correlated random effects panel data specification. Consistent with prior studies of the nonelderly population, dental service use was not sensitive to out-of-pocket prices. However, private dental insurance increased preventive service use by 25%, and dental coverage through Medicaid increased basic and major service use by 23% and 36%, respectively. The use of services was more responsive to dental insurance for women than men. These estimates suggest that a Medicare dental benefit could significantly increase dental service use by older Americans.

Diversity in the use of specialized dental services by older adults in the United States.

OBJECTIVES: We estimated the use of any dental services and the use of specific types of dental services conditional on any dental use for adults 50 and over in the United States to analyze: a) disparities in the use of specialized dental services and b) whether older adults receiving routine dental care use fewer expensive specialized dental services. METHODS: We relied on data tabulations and estimated logistic regressions from the 2014 Medical Expenditure Panel Study to analyze the influence of various covariates such as age, race/ethnicity, education, dental insurance, income, and health status on the likelihood of a) using any dental care and b) using routine dental care (prophylaxis, examinations, bitewings, etc.) and specialized services for restorative, periodontal, oral surgery, or prosthetic dental care conditional on using any dental care. RESULTS: We found a) lower use of specialized services among higher income, more educated, healthier, nonminority older adults and b) association between lower use of routine dental care and higher use of expensive restorative, oral surgery, and prosthetic dental services. CONCLUSIONS: Our study identifies diversity in the use of specialized dental services among an older adult population and suggests that more widespread use of routine dental services could potentially improve oral health and limit the need for expensive specialized dental care for this population.

Projecting the Demand for Dental Care in 2040.

The purpose of this study was to provide a forward-thinking assessment of the underlying factors likely to impact trends in dental care demand and the need for dental providers in 2020, 2025, and beyond. Dental workforce trends and their likely impact on the need for dentists are a function of predicted dental care demand, which will in turn be determined by the size and characteristics of our population size, economic outlook, the state of public and private dental care insurance, trends in dental care delivery, professionally determined dental care need, and population health beliefs. Projecting rates of dental care utilization far into the future is difficult because projections must be made using historical data, and established trends may not persist if there is structural change in the future. Nonetheless, when structural change occurs, it does not typically affect all aspects of the economy, so there is value in describing the likely future impact of current trends. This article was written as part of the project "Advancing Dental Education in the 21st Century."

Projections Of Dental Care Use Through 2026: Preventive Care To Increase While Treatment Will Decline.

This study provides a forward-thinking assessment of the factors likely to affect future trends in dental care in the United States. We developed a forecasting model based on historical data from the Medical Expenditure Panel Survey to determine how demographic trends and recent health care policies will affect dental care use in the future. Our forecasts suggest that the medical and dental insurance reforms instituted under the Affordable Care Act will increase rates of dental care use and the number of dental visits, with utilization rates reaching 47 percent in 2026 and the number of visits reaching 334 million, under optimistic assumptions about take-up of pediatric dental coverage. Our forecasting model also indicates that visits for preventive dental care will increase in the future, while visits for dental treatment will decline. Our forecasts can be used to infer future need for different types of dental care providers and to provide policy makers with the information needed to consider the expansion of mandates for dental benefit coverage to adult populations covered by Medicaid, Medicare, and individual and small-group plans sold on health insurance exchanges.

Differences Among Older Adults in the Types of Dental Services Used in the United States.

The purpose of this article is to explore differences in the socioeconomic, demographic characteristics of older adults in the United States with respect to their use of different types of dental care services. The 2008 Health and Retirement Study (HRS) collected information about patterns of dental care use and oral health from individuals aged 55 years and older in the United States. We analyze these data and explore patterns of service use by key characteristics before modeling the relationship between service use type and those characteristics. The most commonly used service category was fillings, inlays, or bonding, reported by 43.6% of those with any utilization. Just over one third of those with any utilization reported a visit for a crown, implant, or prosthesis, and one quarter reported a gum treatment or tooth extraction. The strongest consistent predictors of use type are denture, dentate, and oral health status along with dental insurance coverage and wealth. Our results provide insights into the need for public policies to address inequalities in access to dental services among an older US population. Our findings show that lower income, less wealthy elderly with poor oral health are more likely to not use any dental services rather than using only preventive dental care, and that cost prevents most non-users who say they need dental care from going to the dentist. These results suggest a serious access problem and one that ultimately produces even worse oral health and expensive major procedures for this population in the future.

Dental Visit Utilization Procedures and Episodes of Treatment.

This investigation describes the factors associated with patients' initial decisions to seek dental care, including the corresponding number of visits and the types of services received during a dental visit episode. Data came from the nationally representative Medical Expenditure Panel Survey (MEPS). Episode-specific dental visits were further classified into three categories, based on type of services received: preventive, treatment-based, or a combination. Among individuals with a visit episode, 78% of the episodes consisted of a single visit. Within an episode, as the number of visits increased, the proportion of initial visits that were of the preventive type decreased.The findings showed that the primary driver of oral healthcare utilization in the United States is preventive care. As new health policy is developed, it is hoped that prevention will remain a central focus in dentistry and that all segments of the population will be able reap its benefits.

Increasing Access to Dental and Medical Care by Allowing Greater Flexibility in Scope of Practice.

In recent years, advocates for increasing access to medical and oral health care have argued for expanding the scope of practice of dentists and physicians. Although this idea may have merit, significant legal and other barriers stand in the way of allowing dentists to do more primary health care, physicians to do more oral health care, and both professions to collaborate. State practice acts, standards of care, and professional school curricula all support the historical separation between the 2 professions. Current laws do not contemplate working across professional boundaries, leaving providers who try vulnerable to legal penalties. Here we examine the legal, regulatory, and training barriers to dental and medical professionals performing services outside their traditional scope of practice.

A Research Note on Transitions in Out-of-Pocket Spending on Dental Services.

OBJECTIVE: We analyze correlates of the direction and magnitude of changes in out-of-pocket (OOP) payments for dental care by older Americans over a recent 4-year period. METHODS: We analyzed data from the 2006 and 2008 waves of the Health and Retirement Study. We estimated multinomial logistic models of the direction and linear regression models of the amounts of OOP changes over survey periods. RESULTS: Financial-based factors were more strongly associated with the direction and magnitude of changing self-payments for dental care than were health factors. DISCUSSION: Findings suggested that dental coverage, income, and wealth and changes in these financial factors were more strongly correlated with the persistence of and changes in OOP payments for dental care over time than were health status and changes in health status. The sensitivity to dental coverage changes should be considered as insurance and retirement policy reforms are deliberated.

Dental use and expenditures for older uninsured Americans: the simulated impact of expanded coverage.

OBJECTIVE: To determine if providing dental insurance to older Americans would close the current gaps in dental use and expenditure between insured and uninsured older Americans. DATA SOURCES/STUDY SETTING: We used data from the 2008 Health and Retirement Survey (HRS) supplemented by data from the 2006 Medical Expenditure Panel Survey (MEPS). STUDY DESIGN: We compared the simulated dental use and expenditures rates of newly insured persons against the corresponding rates for those previously insured. DATA COLLECTION/EXTRACTION METHODS: The HRS is a nationally representative survey administered by the Institute for Social Research (ISR). The MEPS is a nationally representative household survey sponsored by the Agency for Healthcare Research and Quality (AHRQ). PRINCIPAL FINDINGS: We found that expanding dental coverage to older uninsured Americans would close previous gaps in dental use and expense between uninsured and insured noninstitutionalized Americans 55 years and older. CONCLUSIONS: Providing dental coverage to previously uninsured older adults would produce estimated monthly costs net of markups for administrative costs that comport closely to current market rates. Estimates also suggest that the total cost of providing dental coverage targeted specifically to nonusers of dental care may be less than similar costs for prior users.

The effect of dental insurance on the use of dental care for older adults: a partial identification analysis.

We evaluate the impact of dental insurance on the use of dental services using a potential outcomes identification framework designed to handle uncertainty created by unknown counterfactuals-that is, the endogenous selection problem-and uncertainty about the reliability of self-reported insurance status. Using data from the health and retirement study, we estimate that utilization rates of adults older than 50 years would increase from 75% to around 80% under universal dental coverage.

Dental procedures among children age birth to 20, United States, 1999 and 2009.

OBJECTIVE: To describe dental procedures received by US children and adolescents by poverty status and dental insurance coverage. METHODS: Data for this analysis came from the 1999 and 2009 Medical Expenditure Panel Surveys. The primary outcome variable represented the types of dental procedures that were received during dental visits in the preceding year. Descriptive variables included dental insurance and poverty status. Analysis was restricted to children from birth to 20 years. RESULTS: Overall, diagnostic (41.2 percent) and preventive (35.8 percent) procedures accounted for most of the procedures received by children from birth to 20 years of age, while restorative procedures accounted for just 5 percent. Children from low-income families received a higher proportion of restorative procedures than children in higher-income families. The proportion of diagnostic and preventive services was lower among uninsured children than among publicly insured children. Orthodontic services, on the other hand, represented a greater percentage of these procedures among uninsured children than among publicly insured children. DISCUSSION: The vast majority of procedures received by children from birth to 20 years were diagnostic and preventive. Most children with at least one dental visit received a diagnostic or preventive service. Between 1999 and 2009, the proportion of all services received accounted for by diagnostic or preventive services increased. However, the proportion in which each type of procedure was received by children who made at least one visit who received did not change.

Response error in reporting dental coverage by older Americans in the health and retirement study.

The aim of this research was to analyze the inconsistency in responses to survey questions within the Health and Retirement Study (HRS) regarding insurance coverage of dental services. Self-reports of dental coverage in the dental services section were compared with those in the insurance section of the 2002 HRS to identify inconsistent responses. Logistic regression identified characteristics of persons reporting discrepancies and assessed the effect of measurement error on dental coverage coefficient estimates in dental utilization models. In 18% of cases, data reported in the insurance section contradicted data reported in the dental use section of the HRS by those who said insurance at least partially covered (or would have covered) their (hypothetical) dental use. Additional findings included distinct characteristics of persons with potential reporting errors and a downward bias to the regression coefficient for coverage in a dental use model without controls for inconsistent self-reports of coverage. This study offers evidence for the need to validate self-reports of dental insurance coverage among a survey population of older Americans to obtain more accurate estimates of coverage and its impact on dental utilization.

Dental care coverage and use: modeling limitations and opportunities.

OBJECTIVES: We examined why older US adults without dental care coverage and use would have lower use rates if offered coverage than do those who currently have coverage. METHODS: We used data from the 2008 Health and Retirement Study to estimate a multinomial logistic model to analyze the influence of personal characteristics in the grouping of older US adults into those with and those without dental care coverage and dental care use. RESULTS: Compared with persons with no coverage and no dental care use, users of dental care with coverage were more likely to be younger, female, wealthier, college graduates, married, in excellent or very good health, and not missing all their permanent teeth. CONCLUSIONS: Providing dental care coverage to uninsured older US adults without use will not necessarily result in use rates similar to those with prior coverage and use. We have offered a model using modifiable factors that may help policy planners facilitate programs to increase dental care coverage uptake and use.

Dental service mix among older adults aged 65 and over, United States, 1999 and 2009.

OBJECTIVES: The oral health of older Americans will assume increasing importance because of their increasing numbers and the evolving connections between oral health and general health. To establish a baseline and provide data for oral health workforce models, this report describes the types of dental procedures received by US adults 65 years and older in 2009 and looks at trends since 1999. METHODS: Data for this analysis came from the 1999 and 2009 Medical Expenditure Panel Survey. The primary outcome variable represented the types of dental procedures that were received during a dental visit in the preceding year. Descriptive variables included dental insurance and poverty status. Analysis was restricted to adults aged 65 and over. RESULTS: In 2009, diagnostic and preventive procedures accounted for almost three-quarters of all services. Compared with services received by those with private insurance, there were significantly fewer diagnostic and endodontic procedures among those with public coverage. Between 1999 and 2009, the proportion of preventive services significantly increased, whereas the proportion of restorative and endodontic services significantly decreased. Also, the likelihood of receiving preventive procedures increased, whereas the probability of receiving restorative or endodontic services decreased. CONCLUSIONS: Findings point to a shift in the mix of dental services received by older adults during the two periods. The predominance of diagnostic and preventive procedures has important access and workforce implications. An expanded role for dental hygienists in helping to meet the oral health needs of older adults is possible given a hygienist's current scope of practice.
