The Medicare Part D prescription drug benefit includes a $265 deductible, an insured period during which the beneficiary pays 25%of drug costs from $265 to $2,400, and a coverage gap when the beneficiary pays 100 percent of drug costs until reaching the catastrophic limit of $3,850; then they pay 5%.
A new study found elderly Medicare patients with depression enrolled in stand-alone Part D plans in 2007 reduced their use of antidepressants during the Medicare Part D coverage gap.
In fact, a full gap in drug coverage resulted in a 12.1% reduction in antidepressant use, particularly for brand-name drugs.
