SEER-Medicare: Available Files by Year
Note: Given a new agreement between NCI and CMS, starting with the data released in 2020 all Medicare data included in SEER-Medicare will be obtained from CMS’s CCW. As such, in 2020 and moving forward the included Medicare data will only be available starting in 1999. The SEER data included in SEER-Medicare will also be truncated to include cases diagnosed beginning in 1999.
