Payment discrepancies and access to primary care physicians for dual-eligible Medicare-Medicaid beneficiaries.
This study examined whether the Affordable Care Act (ACA) primary care fee bump for dual-eligible Medicare-Medicaid beneficiaries impacted primary care physicians (PCP) acceptance of duals. The authors assessed differences in the likelihood that PCPs had dual caseloads of ≥10% or 20% in states with lower versus full dual reimbursement using linear probability models adjusted for physician and area-level traits. The proportion of PCPs with dual caseloads of ≥10% or 20% decreased significantly between 2012 and 2017. The fee bump was not consistently associated with increases in dual caseloads.

Primary care access to new patient appointments for California Medicaid enrollees: a simulated patient study.
Investigators evaluated variation in the availability of primary care new patient appointments for Medi-Cal (California Medicaid) enrollees in Northern California and its relationship to emergency department (ED) use after Medicaid expansion. Data from the California Health Interview Survey, Medi-Cal enrollment reports, and California hospital discharge records were used. The investigators found that access to primary care in Northern California was limited for new patient Medi-Cal enrollees and varied across counties, despite standard statewide reimbursement rates. Further, counties with more limited access to primary care new patient appointments had higher ED use by Medi-Cal enrollees.

Narrow provider networks and willingness to pay for continuity of care and network breadth.
This study examined choices of health plans in a private health insurance exchange where consumers choose among one broad network and four narrow network plans. The willingness to pay for a network that covers consumers' usual source of care was between $84 and $275/month (for primary care) and between $0 and $115/month (for specialists). The investigators also found that, given that a network covers their usual source of care, consumers show aversion only to the narrowest networks.
