1 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

2 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

11 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 2009 409 plans in 2006 => 308 in 2009 2009 Six states have <=5 plans, Nevada has 1 2009 Six states have <=5 plans, Nevada has 1

12 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

13 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

14 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
