The HHS Office of Inspector General (OIG) has released another in series of Congressionally-mandated reports on Medicare market shares of mail order diabetes test strips, this one covering the three-month period after implementation of the National Mail-Order recompete on July 1, 2016. This market share data is intended to help CMS determine if competitive bidding contract suppliers meet a Medicare Improvements for Patients and Providers Act (MIPPA requirement that they provide at least 50 percent, by volume, of the types of diabetes test strips provided to Medicare beneficiaries. According to the OIG, the top strip type made up 43 percent of the mail-order market, and the top 10 types of strips accounted for 98 percent of the market during this period. A supplier could comply with the MIPPA 50-percent rule by committing to provide two strip types.
