This variable indicates the date the second Comprehensive Medication Review (CMR) with written summary in CMS standardized format was received. Note that for 2016+ this is the date of the last CMR review during the year, if more than one CMR was provided.
CMS created the MTM File from information submitted by Part D plan sponsors to CMS’s Health Plan Management System (HPMS).
This field is only populated if the variable CMR_RECEIVED_NUM is greater than 1. For 2013-2015, there are fields for five CMR dates, see variables (CMR_RECEIVED_DT1 - CMR_RECEIVED_DT5). Note that for 2016+ there are only two CMR_RECEIVED_DT fields – one for the initial CMR (the field called CMR_RECEIVED_DT1) and one for the final date (this field).
