Overpayment Letters: Look for Blue Envelopes
On August 13, 2012, CGS began sending overpayment letters (demand letters) in light blue envelopes. Requests for repayment of Medicare funds are time-sensitive, and we hope that this change in envelope color will help you quickly and easily identify these requests. Please note: due to the limited quantity of blue envelopes available at this time, you may continue to receive some overpayment letters in white envelopes over the next several weeks. We will also mail any overpayment letters longer than 8 pages in larger white envelopes (it is not common for overpayment letters to exceed 8 pages).
Other things you should know:
- CGS uses the Healthcare Integrated General Ledger Accounting System (HIGLAS). HIGLAS is the standard accounting and payment system for Medicare and Medicaid, and all demand letters from CGS are issued through HIGLAS.
- At this time, HIGLAS demand letters are automatically sent to the physical address on file for the specific provider, based on the completed CMS-855 enrollment form.
- We ask that you alert staff within your facility, practice or place of business to watch for these light blue envelopes so you can take the appropriate action quickly (e.g., refund the requested amount or file an appeal).
