The impact of citizenship documentation requirements on access to medicaid for pregnant women in Oregon.

The federal Deficit Reduction Act of 2005 mandated citizenship documentation from all Medicaid applicants as a condition of eligibility and was implemented in Oregon on September 1, 2006. We assessed whether new citizenship documentation requirements were associated with delays in Medicaid authorization for newly pregnant eligible applicants during the first nine months of DRA implementation in Oregon. We conducted a pre-post analysis of administrative records to compare the length of time between Medicaid application and authorization for all newly pregnant, Medicaid-eligible applicants in Oregon (n = 29,284), nine months before and after September 1, 2006.
