Pricing Methodology Explanation
The NADAC was calculated using information from the most recently completed pharmacy survey.
The CMS Covered Outpatient File drug category type of S/I/N (Single Source/Innovator/Non-Innovator) has not been applied. Most S/I drugs with the same strength, dosage form and route of administration were grouped together for the purpose of the NADAC calculation and N drugs were also grouped together. In some cases, however, in calculating a NADAC, the CMS S/I/N designation was not applied when the state Medicaid brand or generic payment practices for these drugs generally differed from the CMS Covered Outpatient File designation.
