Dual Eligibles with Mental Disorders and Medicare Part D: How are They Faring? Julie Donohue University of Pittsburgh Haiden Huskamp Harvard Medical School Sam Zuvekas Agency for Healthcare Research and Quality
Context 6 million Medicare beneficiaries dually eligible for Medicaid moved to Medicare Part D drug plans. 6 million Medicare beneficiaries dually eligible for Medicaid moved to Medicare Part D drug plans. Random assignment to one of multiple benchmark plans, can switch Random assignment to one of multiple benchmark plans, can switch Estimated 60% of disabled and 20% of elderly dual- eligibles have mental disorders Estimated 60% of disabled and 20% of elderly dual- eligibles have mental disorders Protections Protections – “All or substantially all” rule for antidepressants, antipsychotics, and anticonvulsants – Fixed copay for generics, slightly higher for branded drugs, can’t use cost-sharing tiers – Risk adjusted payments to PDPs

Other Findings from the Literature Medication Discontinuities Medication Discontinuities – Some evidence of problems accessing particular medications (Hall et al 2007; West 2007, 2009) Psychotropic Drug Prices Psychotropic Drug Prices – Frank and Newhouse (2008) some evidence that prices for antipsychotics increased under Part D Plan Choice Plan Choice – Most Dual Eligibles assigned randomly, few switch plans (11% in 2006, Neuman et al. 2007) – Reduction in the Number of Benchmark Plans 409 plans in 2006 => 308 in plans in 2006 => 308 in Six states have <=5 plans, Nevada has Six states have <=5 plans, Nevada has 1
Summary and Implications: Out-of-Pocket Costs Major Change in Financing of Psychotropic Medications: Major Change in Financing of Psychotropic Medications: – Out of pocket costs decreased for non dual- eligibles – Out of pocket costs flat for dual-eligibles – Some indirect evidence of medication discontinuities
Summary and Implications: Formulary Coverage Formulary coverage relatively generous Formulary coverage relatively generous – But gaps for some formulations – Increasing use of utilization management Consider monitoring prior authorization approval rates, include in plan performance Consider alternatives to random assignment
Summary and Implications: PDP Market PDPs exiting from market PDPs exiting from market – Limits choice – Reassignment may lead to medication discontinuities – Doubling of PDP risk corridors in 2008 exposes plans to greater risk and may lead to further plan exits if risk adjustment doesn’t accurately reflect dual eligibles expected costs Consider changes in risk adjustment systems to include drug utilization Consider exposing PDPs to less risk for dual- eligibles
