## Abstract

This interim final rule with comment period revises the regulatory text to accurately reflect the applicable statutory language describing the rebate calculation for line extension drugs, which was revised by the Bipartisan Budget Act (BBA) of 2018. In addition, we also are issuing a final rule which responds to comments on the definition and identification of line extension drugs for which we requested additional comments in the Covered Outpatient Drugs final rule with comment period published in the February 1, 2016 Federal Register.
