This study compared beneficiary voluntary disenrollment (withdrawal) from Medicare Preferred Provider Organization (PPO) demonstration plans with voluntary disenrollment from Medicare health maintenance organization (HMO) plans. The PPO demonstration seeks to provide beneficiaries more and better Medicare options.
Researchers found disenrollment rates were more than 3 percentage points higher among PPO demonstration plan participants than among HMO participants in the same markets. Disenrollees from PPOs were more likely than those from HMOs to cite issues with premiums or co-payment amounts, but, PPO disenrollees were less likely to cite problems with access to care or service.
