State Medicaid Coverage and Reimbursement of Adult Vaccines Administered by Physicians and Pharmacists.

Introduction: Effective from October 2023, federal law requires Medicaid programs to cover all recommended adult vaccines administered by physicians with no cost sharing for all eligibility groups. However, uniform coverage does not always translate to optimal uptake. Rather, other factors such as Medicaid reimbursement rates influence vaccine access and ultimately patient uptake. This study reviewed Medicaid policies to understand vaccine coverage and reimbursement, for both physicians and pharmacists, in all 50 U.S. states; Washington, DC; and Puerto Rico (collectively referred to as states). Methods: Between March and September 2022, the researchers reviewed states' public Medicaid policies regarding adult vaccines, focusing on the service of injectable vaccine administration and 3 products: hepatitis A, 9-valent human papilloma virus, and 23-valent pneumococcal polysaccharide. Results: Among 50 states with available data, 7 (14%) restricted Medicaid coverage for hepatitis A, 9-valent human papilloma virus, and/or 23-valent pneumococcal polysaccharide administered by physicians, and 15 (30%) did so for pharmacists. Median physician reimbursement rate was below the private sector rate for hepatitis A (89%) and 9-valent human papilloma virus (94%) but above the rate for 23-valent pneumococcal polysaccharide (108%). Median physician reimbursement for vaccine administration during an office visit was $11.86; the median pharmacist administration fee was $10.67. Conclusions: Although federal law now requires all state Medicaid programs to cover, without cost sharing, all recommended adult vaccines administered by physicians, equitable vaccine access may be hindered by state coverage restrictions for pharmacists and by relatively low reimbursement rates relative to Medicare and commercial coverage for both physicians and pharmacists.

Attitudes and Beliefs around the Value of Vaccination in the United States.

Despite the benefits of immunization, differences in attitudes persist toward vaccines. We captured individuals' perceptions of vaccines and vaccination across the United States (US) to inform vaccine-related policy development. A survey was completed by 5000 respondents from 10 states. Respondents were screened for inclusion, which included individuals ≥ 18 years of age that had received a vaccine or were unvaccinated but indicated a favorable or neutral attitude towards vaccinations. Participants were excluded if they indicated they did not support the idea of vaccinations. Questions explored perceptions of vaccines for all age groups. Among unvaccinated individuals, the most common concerns were about safety (38%). Most respondents (95%) highlighted the importance of state immunization programs for disease prevention. Access to health and immunization records and immunization information systems were important to 96% and 88% of respondents, respectively, for future health planning. Doctors and healthcare professionals (HCPs) were considered trusted sources for vaccine information (95%). Overall, respondents recognized the importance of vaccination, but documented concerns among the unvaccinated indicated a need for greater promotion regarding vaccine safety. Doctors and HCPs, as trusted information sources, should continue to and increasingly advocate for the importance of immunization to increase vaccine uptake.

Availability of Adult Vaccination Services by Provider Type and Setting.

INTRODUCTION: Knowledge regarding the benefits for adult vaccination services under Medicaid's fee-for-service arrangement is dated; little is known regarding the availability of vaccination services for adult Medicaid beneficiaries in MCO arrangements. This study evaluates the availability of provider reimbursement benefits for adult vaccination services under fee-for-service and MCO arrangements for different types of healthcare providers and settings. METHODS: A total of 43 Medicaid directors across the 50 U.S. states and the District of Columbia participated in a semistructured survey conducted from June 2018 to June 2019 (43/51). The frequency of Medicaid fee-for-service and MCO arrangements reporting reimbursement for adult vaccination services by various provider types and settings were assessed in 2019. Elements of vaccination services examined in this study were vaccine purchase, vaccine administration, and vaccination-related counseling. RESULTS: Under fee-for-service, 41 Medicaid programs reimburse primary care providers for adult vaccine purchase (41/43); fewer programs reimburse vaccine administration and vaccination-related counseling (33/43 and 30/43, respectively). Similar results were observed for obstetricians-gynecologists, nurse practitioners, and pharmacies. Although 24 fee-for-service (24/43) and 23 MCO (23/34) arrangements cover adult vaccination services in most settings, long-term care facilities have the lowest reported reimbursement eligibility. CONCLUSIONS: In most jurisdictions, vaccination services for adult Medicaid beneficiaries are available for a variety of healthcare provider types and settings under both fee-for-service and MCO arrangements. However, because provider reimbursement benefits remain inconsistent for adult vaccination counseling services and within long-term care facilities, access to adult vaccination services may be reduced for Medicaid beneficiaries who depend on these resources.

State Policies on Access to Vaccination Services for Low-Income Adults.

Importance: State vaccination benefits coverage and access for adult Medicaid beneficiaries vary substantially. Multiple studies have documented lower vaccination uptake in publicly insured adults compared with privately insured adults. Objective: To evaluate adult Medicaid beneficiaries' access to adult immunization services through review of vaccination benefits coverage in Medicaid programs across the 50 states and the District of Columbia. Design, Setting, and Participants: A public domain document review with supplemental semistructured telephone survey was conducted between June 1, 2018, and June 14, 2019, to evaluate vaccination services benefits in fee-for-service and managed care organization arrangements for adult Medicaid beneficiaries in the 50 states and the District of Columbia (total, 51 Medicaid programs). Exposures: Document review of benefits coverage for adult immunization services and supplemental survey with validation of document review findings. Main Outcomes and Measures: Benefits coverage for adult Medicaid beneficiaries and reimbursement amounts for vaccine purchase and administration. Results: Public domain document review was completed for all 51 jurisdictions. Among these, 44 Medicaid programs (86%) validated document review findings and completed the survey. Only 22 Medicaid programs (43%) covered all 13 Advisory Committee on Immunization Practices-recommended adult immunizations under both fee-for-service and managed care organization arrangements. Most fee-for-service arrangements (37 of 49) reimbursed health care professionals using any of the 4 approved vaccine administration codes; however, 8 of 49 programs did not separately reimburse for vaccine administration to adult Medicaid beneficiaries. Depending on administration route, median reimbursement for adult vaccine administration ranged from $9.81 to $13.98 per dose. Median per-dose reimbursement for adult vaccine purchase was highest for 9-valent human papillomavirus vaccine ($204.87) and lowest for Haemophilus influenzae type b vaccine ($18.09). Median reimbursement was below the private sector price for 7 of the 13 included vaccines. Conclusions and Relevance: Even in programs with complete vaccination benefits coverage, reimbursement amounts to health care professionals for vaccine purchase and administration may not fully cover vaccination provision costs. Reimbursement amounts below costs may reduce incentives for health care professionals to vaccinate low-income adults and thereby limit Medicaid adult beneficiary access to vaccination.
