A new OIG report, “Part B Payments for Drugs Infused through Durable Medical Equipment,” calls for changes in the Medicare reimbursement methodology for Part B infusion drugs administered in conjunction with DME in light of potentially inaccurate pricing. By way of background, DME infusion drugs are reimbursed at 95% of the drug’s average wholesale price (AWP) in effect on October 1, 2003, compared to 106% of the average sales price (ASP) for most Part B drugs. Based on a comparison of actual Medicare reimbursement and the amount that would have been paid under the ASP methodology for each DME infusion drug from 2005 to 2011, the OIG found that payment exceeded ASPs by 54%-122% annually. On the other hand, reimbursement for up to one-third of DME infusion drugs were below the ASP, indicating that in some cases Medicare may underpay for these drugs. On the whole, the OIG estimates that Medicare spending on DME infusion drugs would have been cut by 44% ($334 million) between 2005 and 2011 if payment had been based on ASP. The OIG recommends that CMS either (1) seek legislation requiring DME infusion drug payment to be based on ASP, or (2) include DME infusion drugs in the next round of the DMEPOS competitive bidding program. CMS was noncommittal on legislative changes, but said it would include DME infusion drugs in the next round of competitive bidding (CMS has not yet provided other details on future expansion of competitive bidding).
