AHIP engaged Milliman, an actuarial consulting firm, to analyze actual rebate data and shed light on (1) the prevalence of drugs with rebates; (2) rebate levels as a percentage of drug spend by level and type of market competition; and (3) average annual cost and price trends for drugs with and without rebates. Throughout the report and the excerpts below, rebate refers only to manufacturer rebates and excludes pharmacy rebates.
The key findings of the Milliman report include:
We believe that the report’s findings support the following AHIP conclusions:
The Milliman Prescription Drug Rebates and Part D Drug Costs Analysis findings include:
Most prescribed medications are not rebated by drug makers.
89% of prescriptions written in 2016 had no rebates, the vast majority of which include generic drugs that generally lack rebates.
81% of all Part D drugs analyzed did not have rebates from drug makers in 2016, and 64% of brand drugs analyzed did not have rebates.
For 2016, brand drugs with manufacturer rebates had lower average annual gross cost per beneficiary than brand drugs without rebates.
Among brand drugs with rebates from drug makers, drug price trends (per unit) were similar for:
Among brand drugs with manufacturer rebates, rebates as a percentage of total drug spending were on average:
Highest for drugs with direct brand and generic competition, &
Lowest for protected class drugs.
Only 13% of the 2016 protected class drugs analyzed had manufacturer rebates.
The rebates for protected class drugs with rebates averaged 14% of drug spend — significantly lower than rebate levels for drugs with direct brand competition (i.e., 39% of drug spend).
AHIP notes that when it comes to out-of-control drug costs, the problem is the price. Lower drug prices are an essential part of making coverage and care more affordable, and there are no barriers for drug manufacturers to voluntarily reduce their prices. Health insurance providers encourage drug makers to work constructively with our industry to lower drug prices and costs for all Americans.
