Using data from the Medical Expenditure Panel Survey-Household Component and the National Health Interview Survey, I tested for changes in access to care and affordability around age sixty-five, when most people gain eligibility for Medicare. I found that Medicare eligibility is associated with a 1.5-percentage-point reduction in reports of being unable to get necessary care (a 50.9 percent reduction compared with the percentage at age sixty-four) and a 4.1-percentage-point (45.3 percent) reduction in not being able to get needed care because of the cost. Recently, policy makers have proposed various ways of extending Medicare coverage. These results suggest that incremental Medicare expansions could have positive access and affordability benefits for enrollees compared with the insurance options available to them before they turn sixty-five.","is_dataset_classified":null,"base_score":3.4339872044851463,"endowment":3.4339872044851463,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"33523737","pmcid":null,"openalex_id":"https://openalex.org/W3127335219","authors":[],"funders":[],"total_grants":0,"fwci":6.0629,"citation_percentile":0.96136367,"influential_citations":0,"citation_trend":[{"year":2021,"count":4},{"year":2022,"count":5},{"year":2023,"count":7},{"year":2024,"count":10},{"year":2025,"count":4}],"oa_status":"closed","license":null,"oa_locations":[{"url":"https://doi.org/10.1377/hlthaff.2020.00940","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/33523737","host_type":"repository"}],"fields_of_study":["Healthcare Policy and Management","Global Health Care Issues","Retirement, Disability, and Employment"],"mesh_terms":["Aged","Costs and Cost Analysis","Delivery of Health Care","Eligibility Determination","Health Expenditures","Medicare","Humans","United States","Insurance Coverage"],"keywords":["Medical Expenditure Panel Survey","Health insurance","Medicare Part B","Health care","National Health Interview Survey","Percentage point","Medical care","Actuarial science","Panel survey","Medicine","Point (geometry)","Patient Protection and Affordable Care Act","Business","Family medicine","Environmental health","Demographic economics","Finance","Payment","Economics","Economic growth","Population"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Decent work and economic growth"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-11T18:44:32.410334Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
