Note to HEDIS Requestors about File Size (3/13/2020)

It has  come to our attention that many HPs are sending very large files containing multiple name variants for the same member.  While we understand the rationale for doing this is to increase the probability of matching member patients in CAIR2, it is also causing the HEDIS  matching process to take much longer as larger files take more time to process.  We are therefore asking HPs who submit member files with multiple variant names to take steps to reduce their input file size in subsequent HEDIS requests by eliminating all non-matching variants member names when a member is successfully matched.  Reducing file sizes will benefit everyone as HPs will get their reports more quickly.   Also, beginning 3/16/2020, CAIR2 will no longer process patient input files with >1M rows to reduce overall processing time.
