CMS's price-substitution policy has saved Medicare and its enrollees $74.3 million since 2013, including nearly a million dollars for 2022.
Since CMS instituted its price-substitution policy in 2013, CMS has implemented price substitutions for 83 drugs. Price substitutions for 26 drugs based on 2022 data saved Medicare and its enrollees $966,307 over 1 year.
CMS could have achieved even greater savings by expanding its criteria for price substitutions.
If CMS expanded its price-substitution criteria to include more drugs, Medicare and its enrollees could have saved up to an additional $8.5 million for 2022.
Potential errors in the average manufacturer price data submitted to CMS prevented OIG from determining whether 30 drugs qualified for a price substitution.
When OIG identifies potential errors during its quarterly analysis of the average sales price and average manufacturer price data, it notifies CMS and requests that CMS review the accuracy of the manufacturers' data.
We continue to support our open recommendation that CMS expand its price-substitution criteria to include additional drugs to more effectively limit excessive payment amounts and to generate greater savings for Medicare and its enrollees. We also encourage CMS to continue to work with manufacturers to review and respond to potential errors in the drug data identified by OIG each quarter to bolster the effectiveness of the price substitution policy.
