PAMA Regulations regarding the data collection period

Under the final rule, laboratories and physician offices are required to report private payor rate and volume data if they have more than $12,500 in Medicare revenues from laboratory services on the CLFS and they receive more than 50 percent of their Medicare revenues from laboratory and physician services during a data collection period. Laboratories will collect private payor data from January 1, 2016 through June 30, 2016 and report it to CMS by March 31, 2017. CMS will post the new Medicare CLFS rates (based on weighted median private payor rates) in November 2017 that will be effective on January 1, 2018. CMS has issued an article, Guidance to Laboratories for Collecting and Reporting Data for the Private Payor Rate Based Payment System along with an FAQ on the subject.
