We will only consider services provided by mental health specialists. Since barriers to care may have evolved after the implementation of the Affordable Care Act in 2014, the search will be limited to studies that use data from January 1, 2014, onward.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>We will search the databases MEDLINE (Ovid), Scopus, and Embase, as well as gray literature and key organizational websites. Study screening will occur in 2 stages: i) titles and abstracts will be screened for key text words, and ii) the full text of potentially relevant sources will be examined in detail against the eligibility criteria. Two reviewers will independently be involved in study selection, and unresolvable issues will be decided by a third reviewer. The review will map extracted data to the Barriers to Health Services Framework, which groups barriers into structural, provider-level, social, and patient-cost barriers. We will provide a narrative summary of our findings and present extracted data in a tabular format.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Review registration:<\/jats:title>\n                    <jats:p>OSF https:\/\/osf.io\/rbxmn<\/jats:p>\n                  <\/jats:sec>","DOI":"10.11124\/jbies-25-00090","type":"journal-article","created":{"date-parts":[[2026,3,6]],"date-time":"2026-03-06T09:01:26Z","timestamp":1772787686000},"page":"1440-1452","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":1,"title":["Barriers to outpatient mental health services experienced by adult Medicaid recipients: a scoping review protocol"],"prefix":"10.11124","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4400-1665","authenticated-orcid":false,"given":"Navdep","family":"Kaur","sequence":"first","affiliation":[{"name":"Department of Epidemiology, Mailman School of Public Health, Columbia University, New York, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5624-021X","authenticated-orcid":false,"given":"Katherine M.","family":"Keyes","sequence":"additional","affiliation":[{"name":"Department of Epidemiology, Mailman School of Public Health, Columbia University, New York, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-8709-5064","authenticated-orcid":false,"given":"Charles C.","family":"Branas","sequence":"additional","affiliation":[{"name":"Department of Epidemiology, Mailman School of Public Health, Columbia University, New York, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2134-4043","authenticated-orcid":false,"given":"Ramin","family":"Mojtabai","sequence":"additional","affiliation":[{"name":"Department of Psychiatry, School of Medicine, Tulane University, New Orleans, LA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3958-5662","authenticated-orcid":false,"given":"Mark","family":"Olfson","sequence":"additional","affiliation":[{"name":"Department of Epidemiology, Mailman School of Public Health, Columbia University, New York, NY, USA"},{"name":"Department of Psychiatry, Columbia University Irving Medical Center, New York, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2026,3,6]]},"reference":[{"issue":"5","key":"R5-20260730","doi-asserted-by":"crossref","first-page":"525","DOI":"10.1001\/jama.2016.9797","article-title":"United States health care reform: progress to date and next steps","volume":"316","author":"Obama","year":"2016","journal-title":"JAMA"},{"issue":"4","key":"R7-20260730","doi-asserted-by":"crossref","first-page":"615-25","DOI":"10.1111\/1475-6773.13311","article-title":"Public insurance expansions and mental health care availability","volume":"55","author":"Blunt","year":"2020","journal-title":"Health Serv Res"},{"issue":"4","key":"R9-20260730","doi-asserted-by":"crossref","first-page":"387-94","DOI":"10.1016\/j.jamcollsurg.2015.12.044","article-title":"Are surgeons being paid fairly by Medicaid?
