Issued by: Centers for Medicare & Medicaid Services (CMS)

Issue Date: January 30, 2019

Program Area: CSR Reconciliation (CSR)

Question: Can issuers resubmit files that CMS has already accepted?

Answer: Yes, issuers may resubmit the file at any point during the data submission period established even if the file was previously accepted. Reconciliation will be conducted on an issuer's most recent, successful (Accepted or Accepted with errors) data submission as of the submission deadline. CMS will consider every resubmission as a new submission, so the filename for the resubmission must be unique and include a new date and time. Issuers must resubmit the entire file (i.e., the full pipe-delimited file) when resubmitting data files.
