Insurance Type and Withdrawal of Life-Sustaining Therapy in Critically Injured Trauma Patients.

Importance: Withdrawal of life-sustaining therapy (WLST) decisions for critically injured trauma patients are complicated and multifactorial, with potential for patients' insurance status to affect decision-making. Objectives: To determine if patient insurance type (private insurance, Medicaid, and uninsured) is associated with time to WLST in critically injured adults cared for at US trauma centers. Design, Setting, and Participants: This retrospective registry-based cohort study included reported data from level I and level II trauma centers in the US that participated in the American College of Surgeons Trauma Quality Improvement Program (TQIP) registry. Participants included adult trauma patients who were injured between January 1, 2017, and December 31, 2020, and required an intensive care unit stay. Patients were excluded if they died on arrival or in the emergency department or had a preexisting do not resuscitate directive. Analyses were performed on December 12, 2023. Exposures: Insurance type (private insurance, Medicaid, uninsured). Main Outcomes and Measures: An adjusted time-to-event analysis for association between insurance status and time to WLST was performed, with analyses accounting for clustering by hospital. Results: This study included 307 731 patients, of whom 160 809 (52.3%) had private insurance, 88 233 (28.6%) had Medicaid, and 58 689 (19.1%) were uninsured. The mean (SD) age was 40.2 (14.1) years, 232 994 (75.7%) were male, 59 551 (19.4%) were African American or Black patients, and 201 012 (65.3%) were White patients. In total, 12 962 patients (4.2%) underwent WLST during their admission. Patients who are uninsured were significantly more likely to undergo earlier WLST compared with those with private insurance (HR, 1.54; 95% CI, 1.46-1.62) and Medicaid (HR, 1.47; 95% CI, 1.39-1.55). This finding was robust to sensitivity analysis excluding patients who died within 48 hours of presentation and after accounting for nonwithdrawal death as a competing risk. Conclusions and Relevance: In this cohort study of US adult trauma patients who were critically injured, patients who were uninsured underwent earlier WLST compared with those with private or Medicaid insurance. Based on our findings, patient's ability to pay was may be associated with a shift in decision-making for WLST, suggesting the influence of socioeconomics on patient outcomes.

Effect of Medicaid expansion on cancer treatment and survival among Medicaid beneficiaries and the uninsured.

BACKGROUND: The Affordable Care Act expanded Medicaid coverage for people with low income in the United States. Expanded insurance coverage could promote more timely access to cancer treatment, which could improve overall survival (OS), yet the long-term effects of Medicaid expansion (ME) remain unknown. We evaluated whether ME was associated with improved timely treatment initiation (TTI) and 3-year OS among patients with breast, cervical, colon, and lung cancers who were affected by the policy. METHODS: Medicaid-insured or uninsured patients aged 40-64 with stage I-III breast, cervical, colon, or non-small cell lung cancer within the National Cancer Database (NCDB). A difference-in-differences (DID) approach was used to compare changes in TTI (within 60 days) and 3-year OS between patients in ME states versus nonexpansion (NE) states before (2010-2013) and after (2015-2018) ME. Adjusted DID estimates for TTI and 3-year OS were calculated using multivariable linear regression and Cox proportional hazards regression models, respectively. RESULTS: ME was associated with a relative increase in TTI within 60 days for breast (DID = 4.6; p < 0.001), cervical (DID = 5.0 p = 0.013), and colon (DID = 4.0, p = 0.008), but not lung cancer (p = 0.505). In Cox regression analysis, ME was associated with improved 3-year OS for breast (DID hazard ratio [HR] = 0.82, p = 0.009), cervical (DID-HR = 0.81, p = 0.048), and lung (DID-HR = 0.87, p = 0.003). Changes in 3-year OS for colon cancer were not statistically different between ME and NE states (DID-HR, 0.77; p = 0.075). CONCLUSIONS: Findings suggest that expanded insurance coverage can improve treatment and survival outcomes among low income and uninsured patients with cancer. As the debate surrounding ME continues nationwide, our findings serve as valuable insights to inform the development of policies aimed at fostering accessible and affordable healthcare for all.

Influence of health insurance on withdrawal of life sustaining treatment for patients with isolated traumatic brain injury: a retrospective multi-center observational cohort study.

BACKGROUND: Healthcare inequities for patients with traumatic brain injury (TBI) represent a major priority area for trauma quality improvement. We hypothesized a relationship between health insurance status and timing of withdrawal of life sustaining treatment (WLST) for adults with severe TBI. METHODS: This multicenter retrospective observational cohort study utilized data collected between 2017 and 2020. We identified adult (age ≥ 16) patients with isolated severe TBI admitted participating Trauma Quality Improvement Program centers. We determined the relationship between insurance status (public, private, and uninsured) and the timing of WLST using a competing risk survival analysis framework adjusting for baseline, clinical, injury and trauma center characteristics. Multivariable cause-specific Cox regressions were used to compute adjusted hazard ratios (HR) reflecting timing of WLST, accounting for mortality events. We also quantified the between-center residual variability in WLST using the median odds ratio (MOR) and measured insurance status association with access to rehabilitation at discharge. RESULTS: We identified 42,111 adults with isolated severe TBI treated across 509 trauma centers across North America. There were 10,771 (25.6%) WLST events in the cohort and a higher unadjusted incidence of WLST events was evident in public insurance patients compared to private or uninsured groups. After adjustment, WLST occurred earlier for publicly insured (HR 1.07, 95% CI 1.02-1.12) and uninsured patients (HR 1.29, 95% CI 1.18-1.41) compared to privately insured patients. Access to rehabilitation was lower for both publicly insured and uninsured patients compared to patients with private insurance. Accounting for case-mix, the MOR was 1.49 (95% CI 1.43-1.55), reflecting significant residual between-center variation in WLST decision-making. CONCLUSIONS: Our findings highlight the presence of disparate WLST practices independently associated with health insurance status. Additionally, these results emphasize between-center variability in WLST, persisting despite adjustments for measurable patient and trauma center characteristics.

Rural-urban disparities and socioeconomic determinants of caesarean delivery rates in Zimbabwe: Evidence from the 2019 National Multiple Indicator Cluster Survey.

Caesarean sections (CSs) have increased globally, with concerns being raised involving overutilisation and inequalities in access. In Zimbabwe, where healthcare access varies greatly, we aimed to analyse factors associated with ever having a CS using the 2019 National Multiple Indicator Cluster Survey. The weighted national CS rate was 10.3%, and CS happened more commonly among women in urban than rural areas (15.7% v. 7.4%; odds ratio (OR) 2.34; (95% confidence interval (CI)) 1.71 - 3.20; p=0.001). Percentages of those having a CS significantly increased with education: overall χ2 for a trend of p=0.001 and wealth quintile, and overall χ2 for a trend of p=0.001. Women with insurance coverage were more likely to have had a CS than those without: 26.7% v. 8.7%; OR 3.82; 95% CI 2.51 - 5.83; p=0.001. The same was the case for women with access to the internet: 15.4% v. 7.0%, OR 2.42; 95%CI 1.71 - 3.41; p=0.001). These findings show an association that could indicate this being overutilised by insured women in urban settings, rather than being accessible based on clinical needs. Further research should explore reasons for these disparities and inform interventions to ensure equitable access to optimum childbirth in Zimbabwe.

Factors affecting decisions of an HMO Drug Exemptions Committee on individual patient requests for coverage of non-formulary drugs.

BACKGROUND: In Israel, coverage of health needs is delivered by four health maintenance organizations (HMOs), which are budgeted by the government according to the recommendations of the National Drug Formulary (NDF) Committee. For medications not listed in the NDF, individuals may request to cover the costs by the HMO Exemptions Committee (DEC). The objectives of the current study, a first of its kind, are to document the DEC decision process, to identify its components and to determine the decisions' clinical outcome. METHODS: This retrospective cohort study included all members (≥ age 18) of the Maccabi Healthcare Service (MHS) who submitted a request to the DEC between June 2017 and December 2018. Collected data include patient demographics, clinical information and components of the decision process. Decision success (i.e., clinical outcome correlated with DEC decision) was determined by clinical outcome over at least one-year follow-up. RESULTS: A total of 335 requests were included. Strong evidence and rare disease were positively associated with approvals, while the availability of alternative treatments and costs were negatively associated. The majority of decisions (75%) met predicted clinical outcomes. Only estimated costs were found to be associated with decision success. CONCLUSIONS: Factors that reduce the potential costs of a requested drug are significantly associated with higher odds for drug approval, but only when the evidence supports potential benefit.

Disparities in satisfaction among insured and uninsured adult outpatient department service users in Southern Ethiopia, 2022: a comparative cross-sectional study.

BACKGROUND: Patient satisfaction is a critical measure of the quality of healthcare services provided by healthcare facilities. However, very few studies, particularly in Ethiopia, which includes the study area, have specifically examined these discrepancies among people who use outpatient care. In this study, satisfaction levels and associated factors were compared between insured and uninsured patients receiving outpatient services at public health institutions in Hadiya Zone, southern Ethiopia. METHODS: A facility-based comparative cross-sectional study design was employed on 630 patients using multistage and systematic random sampling. Data were collected using a pretested and structured interviewer-administered questionnaire. Results of the analysis were presented in text, tables, and graphs as appropriate. Multivariable logistic regression was used to predict associations between predictors and the outcome variable. Statistical significance was declared at p-value < 0.05. RESULTS: Overall, 344(55.48%) patients were satisfied with the service they received, of which 206(65.8%) out of 313 with a 95% CI [60.7-71.2%] were insured and 138(44.95%) out of 307 with a 95% CI [39.4-5.1%] were uninsured. Among insured patients, factors associated with higher satisfaction included having a family size less than five members [AOR = 3.3, 95% CI; 1.5, 7.4], perceived fair waiting time to be seen[AOR = 2.35, 95% CI; 1.02, 5.5], perceived short waiting time to be seen[AOR = 8.12, 95% CI; 1.6, 41.3], having all ordered laboratory tests available within the facility[AOR = 7.89, 95% CI; 3.5, 17.5], having some ordered laboratory tests within the facility[AOR = 2.97, 95% CI; 1.25, 7.01] having all prescribed medications available within the facility[AOR = 16.11, 95% CI; 6.25, 41.5], having some prescribed medications available within the facility[AOR = 13.11, 95% CI; 4.7, 36.4]. Among non-insured patients, factors associated with higher satisfaction included urban residency, a fair and short perceived time to be seen, having ordered laboratory tests within the facility, and having prescribed drugs within the facility. CONCLUSION: This study identified lower overall satisfaction, particularly among uninsured patients. Enrollment in the CBHI program significantly impacted satisfaction, with both groups reporting lower levels compared to enrollment periods. Access to essential services, wait times, and socio-demographic factors identified as associated factors with patient satisfaction regardless of insurance status.

Quantifying the insurance value for rare diseases: Duchenne muscular dystrophy.

OBJECTIVES: To quantify the magnitude of an ISPOR novel value element, insurance value, as applied to new treatments for a rare, severe disease with pediatric onset: Duchenne muscular dystrophy (DMD). STUDY DESIGN: Prospective survey of individuals planning to have children in the future. METHODS: A survey was administered to US adults (aged ≥ 21 years) planning to have a child in the future to elicit willingness to pay (WTP) for insurance coverage for a new hypothetical DMD treatment that improved mortality and morbidity relative to the current standard of care. To identify an indifference point between status quo insurance and insurance with additional cost that would cover the treatment if respondents had a child with DMD, a multiple random staircase design was used. Insurance value-the value individuals receive from a reduction in future health risks-was calculated as the difference between respondent's WTP and what a risk-neutral individual would pay. The risk-neutral value was the product of the (1) probability of having a child with DMD (decision weighted), (2) quality-adjusted life-years (QALYs) gained from the new treatment, and (3) WTP per QALY. RESULTS: Among 207 respondents, 80.2% (n = 166) were aged 25 to 44 years, and 59.9% (n = 124) were women. WTP for insurance coverage of the hypothetical treatment was $973 annually, whereas the decision-weighted risk-neutral value was $452 per year. Thus, insurance value constituted 53.5% ($520) of value for new DMD treatments. CONCLUSIONS: Individuals planning to have children in the future are willing to pay more for insurance coverage of novel DMD treatments than is assumed under risk-neutral, QALY-based frameworks.

Insurance Instability for Patients With Opioid Use Disorder in the Year After Diagnosis.

Importance: Transitions in insurance coverage may be associated with worse health care outcomes. Little is known about insurance stability for individuals with opioid use disorder (OUD). Objective: To examine insurance transitions among adults with newly diagnosed OUD in the 12 months after diagnosis. Design, Setting, and Participants: Longitudinal cohort study using data from the Massachusetts Public Health Data Warehouse. The cohort includes adults aged 18 to 63 years diagnosed with incident OUD between July 1, 2014, and December 31, 2014, who were enrolled in commercial insurance or Medicaid at diagnosis; individuals diagnosed after 2014 were excluded from the main analyses due to changes in the reporting of insurance claims. Data were analyzed from November 10, 2022, to May 6, 2024. Exposure: Insurance type at time of diagnosis (commercial and Medicaid). Main Outcomes and Measures: The primary outcome was the cumulative incidence of insurance transitions in the 12 months after diagnosis. Logistic regression models were used to generate estimated probabilities of insurance transitions by insurance type and diagnosis for several characteristics including age, race and ethnicity, and whether an individual started medication for OUD (MOUD) within 30 days after diagnosis. Results: There were 20 768 individuals with newly diagnosed OUD between July 1, 2014, and December 31, 2014. Most individuals with newly diagnosed OUD were covered by Medicaid (75.4%). Those with newly diagnosed OUD were primarily male (67% in commercial insurance, 61.8% in Medicaid). In the 12 months following OUD diagnosis, 30.4% of individuals experienced an insurance transition, with adjusted models demonstrating higher transition rates among those starting with Medicaid (31.3%; 95% CI, 30.5%-32.0%) compared with commercial insurance (27.9%; 95% CI, 26.6%-29.1%). The probability of insurance transitions was generally higher for younger individuals than older individuals irrespective of insurance type, although there were notable differences by race and ethnicity. Conclusions and Relevance: This study found that nearly 1 in 3 individuals experience insurance transitions in the 12 months after OUD diagnosis. Insurance transitions may represent an important yet underrecognized factor in OUD treatment outcomes.

Overlap In Carriers And Networks In Medicaid And The Individual Marketplaces.

As people lose Medicaid because of the end of the COVID-19 public health emergency, many states will route former Medicaid managed care enrollees into Affordable Care Act Marketplace coverage with the same carrier. In 2021, 52.1 percent of Medicaid managed care enrollees were enrolled by a carrier that also had a plan on the Marketplace in the same county.

Does Insurance Provide Adequate Coverage for Physical Therapy Visits for Common Orthopedic Diagnoses? A Survey Study.

OBJECTIVES: This study aimed to analyze the association between physical therapists' recommended number of visits for a full recovery from common orthopedic injuries/surgeries and the extent of insurance coverage for these visits. METHODS: A prospective observational study was conducted with board-certified physical therapists. A qualitative questionnaire was used to gather physical therapists' demographics and the recommended number of physical therapy visits to achieve a full recovery after 11 common orthopedic diagnoses. Physical therapists also were asked to report whether they believe that insurance provides an adequate number of visits overall. In addition to the qualitative survey, insurance coverage details of major Alabama companies were obtained for comparison. Descriptive statistics of the participating therapists were analyzed for sex, age, degree/training, and years of experience. Kruskal-Wallis statistics were used to analyze variance between the aforementioned groupings when compared with the reported average number of sessions. RESULTS: The survey (N = 251) collected data on the average number of physical therapy sessions that are necessary for a complete recovery as recommended by physical therapists for 11 common orthopedic diagnoses. From this survey, the average number of necessary visits ranged from 11.3 visits (ankle sprains) to 37.3 visits (anterior cruciate ligament reconstruction), with the overall average number of visits being 23.8. Only 24% of physical therapists believed that insurance companies provided enough coverage. Insurance coverage varied but often required additional procedures to allocate the adequate number of visits for the studied orthopedic pathologies. CONCLUSIONS: The majority of practicing physical therapists in Alabama perceive insufficient insurance coverage for physical therapy visits for most orthopedic diagnoses. This study has implications for healthcare decision making and patient-centered rehabilitation goals. Physicians and physical therapists can use this information to optimize treatment decisions and rehabilitation goals. Patients will benefit from improved physical and economic well-being. This study has the potential to drive further research and influence national insurance policies to better serve patients' needs.

Medicare Eligibility and Changes in Coverage, Access to Care, and Health by Sexual Orientation and Gender Identity.

Importance: Medicare provides nearly universal insurance coverage at age 65 years. However, how Medicare eligibility affects disparities in health insurance coverage, access to care, and health status among individuals by sexual orientation and gender identity is poorly understood. Objective: To assess the association of Medicare eligibility with disparities in health insurance coverage, access to care, and self-reported health status among individuals by sexual orientation and by gender identity. Design, Setting, and Participants: This cross-sectional study used the age discontinuity for Medicare eligibility at age 65 years to isolate the association of Medicare with health insurance coverage, access to care, and self-reported health status, by their sexual orientation and by their gender identity. Data were collected from the Behavioral Risk Factor Surveillance System for respondents from 51 to 79 years old from 2014 to 2021. Data analysis was performed from September 2022 to April 2023. Exposures: Medicare eligibility at age 65 years. Main Outcomes and Measures: Proportions of respondents with health insurance coverage, usual source of care, cost barriers to care, influenza vaccination, and self-reported health status. Results: The study population included 927 952 individuals (mean [SD] age, 64.4 [7.7] years; 524 972 [56.6%] females and 402 670 [43.4%] males), of whom 28 077 (3.03%) identified as a sexual minority-lesbian, gay, bisexual, or another sexual minority identity (LGB+) and 3286 (0.35%) as transgender or gender diverse. Respondents who identified as heterosexual had greater improvements at age 65 years in insurance coverage (4.2 percentage points [pp]; 95% CI, 4.0-4.4 pp) than those who identified as LGB+ (3.6 pp; 95% CI, 2.3-4.8 pp), except when the analysis was limited to a subsample of married respondents. For access to care, improvements in usual source of care, cost barriers to care, and influenza vaccination were larger at age 65 years for heterosexual respondents compared with LGB+ respondents, although confidence intervals were overlapping and less precise for LGB+ individuals. For self-reported health status, the analyses found larger improvements at age 65 years for LGB+ respondents compared with heterosexual respondents. There was considerable heterogeneity by state in disparities by sexual orientation among individuals who were nearly eligible for Medicare (close to 65 years old), with the US South and Central states demonstrating the highest disparities. Among the top-10 highest-disparities states, Medicare eligibility was associated with greater increases in coverage (6.7 pp vs 5.0 pp) and access to a usual source of care (1.4 pp vs 0.6 pp) for LGB+ respondents compared with heterosexual respondents. Conclusions and Relevance: The findings of this cross-sectional study indicate that Medicare eligibility was not associated with consistently greater improvements in health insurance coverage and access to care among LGBTQI+ individuals compared with heterosexual and/or cisgender individuals. However, among sexual minority individuals, Medicare may be associated with closing gaps in self-reported health status, and among states with the highest disparities, it may improve health insurance coverage, access to care, and self-reported health status.

Effects of Affordable Care Act on uninsured hospitalization: Evidence from Texas.

OBJECTIVE: To examine the impact of the Affordable Care Act (ACA) health insurance exchanges (Marketplace) on the rate of uninsured discharges in Texas. DATA SOURCE AND STUDY SETTING: Secondary discharge data from 2011 to 2019 from Texas. STUDY DESIGN: We conducted a retrospective study estimating the effects of the ACA Marketplace using difference-in-difference regressions, with the main outcome being the uninsured discharge rate. We stratified our sample by patient's race, age, gender, urbanicity, major diagnostic categories (MDC), and emergent type of admissions. DATA COLLECTION/EXTRACTION METHODS: We used Texas hospital discharge records for non-elderly adults collected by the state of Texas and included acute care hospitals who reported data from 2011 to 2019. PRINCIPAL FINDINGS: The expansion of insurance through ACA Marketplaces led to reductions in the uninsured discharge rate by 9.9% (95% CI, -17.5%, -2.3%) relative to the baseline mean. The effects of the ACA were felt strongest in counties with any share of Hispanic, in counties with a larger population of Black, and other racial groups, in counties with a significant share of female and older age individuals, in counties considered to be urban, in high-volume diagnoses, and emergent type of admissions. CONCLUSIONS: These findings indicate that the ACA facilitated a shift in hospital payor mix from uninsured to insured.

Sampling coverage of the Arkansas all-payer claims database by County's persistent poverty designation.

OBJECTIVES: To evaluate the quality of Arkansas All-Payer Claims Database (APCD) for disparity research in persistent poverty areas by determining (1) its representativeness of Arkansas population, (2) variation by county, and (3) differences in coverage between persistent poverty and other counties. DATA SOURCES: Cross-sectional study using 2019 Arkansas APCD member enrollment data and county-level data from various agencies. DATA COLLECTION/EXTRACTION METHODS: An alias identifier linked persons across insurance plans. County FIPS codes were used to extract county-level variables. STUDY DESIGN: Cohort 1 included individuals with ≥1 day of medical coverage in 2019. Cohort 2 included individuals with medical coverage in June, 2019. Cohort 3 included individuals with continuous medical coverage in 2019. Sampling proportions of a county's population in the three cohorts were compared between persistent poverty and other counties. Inverse-variance weighted linear regression was used to identify county-level socioeconomic and demographic characteristics associated with inclusion in each cohort. PRINCIPAL FINDINGS: In 2019, 73.6% of Arkansans had medical coverage for ≥1 day (Cohort 1), 66.3% had coverage in June (Cohort 2), and 58.8% had continuous coverage (Cohort 3) in APCD. Sampling proportions varied by county (median[range]: Cohort 1, 78% [58%-95%]; Cohort 2, 71% [51%-88%]; and Cohort 3, 64% [44%-80%]), and were higher among persistent poverty counties than others for all three cohorts (mean [SD], persistent poverty vs. other: Cohort 1: 80.9% [6.4%] vs. 77.1% [6.3%], p = 0.04; Cohort 2: 74.0% [6.4%] vs. 70.1% [6.2%], p = 0.03; Cohort 3: 66.4% [6.1%] vs. 62.7% [6.0%], p = 0.03). In the 2019 APCD, larger counties and those with higher proportions of females or persons 65+ years had higher coverage, whereas counties with higher per capita household income, median home value, or disproportionately more persons of other races (non-White and non-Black) had lower coverage (p < 0.05 for all three cohorts). CONCLUSIONS: The Arkansas APCD had good coverage of Arkansas population. Coverage was higher in persistent poverty counties than others.

Health Insurance Coverage Predicts Health Care Use among Latine Immigrants in Two Policy Contexts.

This study analyzed electronic health record (EHR) data from 2016 through 2019 from a federally qualified health center (FQHC) serving predominantly low-income Latine immigrants in the Washington, D.C. metropolitan area to examine how changes in health insurance coverage relate to changes in health care use. Federally qualified health center clients were insured for an average of 59% to 63% of their annual visits, but about one-third had no coverage throughout the year. Findings from descriptive regression and within-client fixed effects models indicate that in years with higher proportions of insured visits, clients averaged more medical visits and interpreter services but fewer mental health and care coordination visits. Latine immigrant clients in D.C., a city with a universal health insurance option, had health insurance coverage for 89% of their visits, and averaged more medical and fewer coordination visits relative to those in a neighboring county in a state without a universal insurance option.

The impact of insurance status on patient placement into inpatient and outpatient orthopaedic surgical centers.

BACKGROUND: Innovation has fueled the shift from inpatient to outpatient care for orthopaedic joint arthroplasty. Given this transformation, it becomes imperative to understand what factors help assign care-settings to specific patients for the same procedure. While the comorbidities suffered by patients are important considerations, recent research may point to a more complex determination. Differences in reimbursement structures and patient characteristics across various insurance statuses could potentially influence these decisions. METHODS: Retrospective binary logistic and ordinary least square (OLS) regression analyses were employed on de-identified inpatient and outpatient orthopaedic arthroplasty data from Albany Medical Center from 2018 to 2022. Data elements included surgical setting (inpatient vs. outpatient), covariates (age, sex, race, obesity, smoking status), Elixhauser comorbidity indices, and insurance status. RESULTS: Patients insured by Medicare were significantly more likely to be placed in inpatient care-settings for total hip, knee, and ankle arthroplasty when compared to their privately insured counterparts even after Centers for Medicare and Medicaid Services (CMS) removed each individual surgery from its inpatient-only-list (1.65 (p < 0.05), 1.27 (p < 0.05), and 12.93 (p < 0.05) times more likely respectively). When compared to patients insured by the other payers, Medicare patients did not have the most comorbidities (p < 0.05). CONCLUSIONS: Medicare patients were more likely to be placed in inpatient care-settings for hip, knee, and ankle arthroplasty. However, Medicaid patients were shown to have the most comorbidities. It is of value to note Medicare patients billed for outpatient services experience higher coinsurance rates. LEVEL OF EVIDENCE: III.

This study examines formulary coverage of brand-name adalimumab and biosimilars across Medicare Part D plans.

Disparities in State Medicaid Coverage of Tretinoin for Pigmentary Disorders Compared to Acne Vulgaris.

BACKGROUND: Melasma and post-inflammatory hyperpigmentation (PIH) are common cosmetic dermatologic conditions that predominantly affect patients with skin phototypes III-VI. Comparing treatment coverage for these pigmentary disorders to treatment coverage for acne vulgaris may demonstrate disparities in insurance coverage for diseases that primarily affect patients of color. OBJECTIVE: Describe differences in Medicaid coverage for topical tretinoin for melasma and PIH vs. acne vulgaris in all 50 states and the District of Columbia. METHODS: This is a cross-sectional study of Medicaid insurance plans in all 50 states and the District of Columbia conducted between February 1 and 28, 2023. Data was collected from online publicly available preferred drug lists, prior authorization criteria, and email/telephone inquiries. Information was collected regarding coverage restrictions, including age restrictions, diagnostic restrictions, preferred drug status, and prior authorization requirements. RESULTS: Complete coverage data for all three clinical indications was retrieved from 30 (58.8%) states; partial coverage data for acne vulgaris was retrieved from 16 (31.4%) states; no coverage data was retrieved from 5 (9.8%) states. Of states reporting coverage data, topical tretinoin is covered in 45 (97.8%) states for acne vulgaris and 10 (33.3%) states for melasma and post-inflammatory hyperpigmentation. There was decreased Medicaid coverage of topical tretinoin for acne vulgaris compared to melasma and PIH (P<0.05).  Conclusion: There is differential Medicaid coverage for acne vulgaris compared to pigmentary disorders which disproportionately affect patients of color. Greater advocacy is required to ensure equal treatment for conditions that affect racial minority patients. J Drugs Dermatol. 2024;23(6):e151-e153.     doi:10.36849/JDD.8069e  .
