ResDAC Comments
From CY 2017 to CY 2021, the MBSF: Chronic Conditions segment also has a newer (CC30) version. The algorithm used to create the First Occurrence of Colorectal Cancer variable in the CC30 version includes more DX codes and an increased reference period.
The earliest possible date for anyone in the CCW is January 1, 1999. If the beneficiary became eligible for Medicare after that, the earliest possible date will be some time after his/her coverage start date (i.e., the COVSTART variable in the Beneficiary File).
