EpiPen® misclassification cost $1.27B over 10 years, says OIG

If the EpiPen® had been classified as brand name instead of generic for purposes of the Medicaid Drug Rebate Program, CMS would have saved $1.27 billion from 2006 to 2016, the HHS Office of Inspector General (OIG) found. This estimate is far greater than the $465 million settlement that the federal government and EpiPen’s manufacturer, Mylan Inc., entered into in October 2016 concerning the classification of the drug under the Program (see Mylan settles EpiPen Medicaid rebate dispute for $465M, Health Law Daily, October 11, 2016).

“The fact that the EpiPen overpayment is so much more than anyone publicly discussed should worry every taxpayer,” said Sen. Charles Grassley (R-Iowa). Grassley reported that CMS recently provided records showing that Mylan was made aware of the misclassification years ago but failed to act (see Federal EpiPen® spending up 463 percent, Mylan misclassified drug as generic, Health Law Daily, October 6, 2016). At the time Sen. Elizabeth Warren (D-Mass) opposed the settlement, calling it “shamefully weak” (see Warren: EpiPen® Medicaid rebate settlement shows ‘crime does pay,’ Health Law Daily, October 26, 2016).

Manufacturers generally owe a higher rebate amount for brand-name drugs than generic under the Medicaid Drug Rebate Program. The basic rebate amount for a generic drug is based on a percentage (currently 13 percent) of its average manufacturer price (AMP) (see 42 C.F.R. Sec. 447.509). The basic rebate amount for a brand-name drug is based on the greater of (1) a fixed percentage (currently 23.1 percent) of the drug’s AMP; or (2) the different between the drug’s AMP and best price. In addition to the rebate amount, manufacturers of brand-name drugs (and, beginning in 2017, manufacturers of generic drugs) pay an inflation-related rebate amount if a drug’s price has increased more than the rate of inflation.

The EpiPen controversy led Grassley to request that the OIG review the Medicaid Drug Rebate Program (see HHS Inspector General to investigate Medicaid Drug Rebate Program, Health Law Daily, December 12, 2016).
