I cannot find the letter that was sent to me by NYSIF that had the new billing address and had other information about the new NYSIF payment process. Where can I get another copy?

The information that was on the letter with the new address for mailing claims/bills that describes the new NYSIF payment process, effective December 1, 2015 can be found at:
