The House in March passed a bill that caps the out-of-pocket cost of insulin at $35 per month for Medicare Part D beneficiaries and for certain privately insured enrollees. A recent Kaiser Family Foundation analysis found that total out-of-pocket spending by Part D enrollees on insulin quadrupled between 2007 and 2019, reaching nearly $1 billion. If a $35 copay cap had been in place in 2019, Part D enrollees without low-income subsidies would have saved $14 per insulin prescription on average. Meanwhile, another study found that over one in four individual and small group enrollees paid more than an average of $35 per month out of pocket for insulin products in 2018. With a $35 cap, median monthly savings could reach $27 in the individual market and $19 in the small and large group markets.
