title: Effect of Medicare advantage payments on dually eligible Medicare beneficiaries.
abstract: This study estimates the effect of Medicare Advantage (MA) payments and State Medicaid policies on the choice by Medicaid eligible Medicare beneficiaries to either join a MA plan, remain in the fee-for-service (FFS) and enroll in Medicaid (dually enrolled), or remain in FFS Medicare without joining Medicaid. Individual plan choice was modeled using a multinomial logit. The sample includes Medicaid-eligible Medicare beneficiaries (including specified low income Medicare beneficiaries [SLMBs] and qualified Medicare beneficiaries [QMBs]) drawn from the 2000 Medicare Current Beneficiary Survey (MCBS). We find a $10 increase in monthly MA payment reduces the probability of dual enrollment by four percentage points, and FFS Medicare enrollment by 11 percentage points.
