1. When DMAS determines an overpayment has been made to a provider, DMAS shall promptly send the first demand letter requesting a lump sum refund. The overpayment notice contains the necessary information on how to submit an overpayment waiver request form.For now I'm going to fill out the waiver of over payments letter and send it back but I'm still not sure what to do and what will happen? Virginia's unemployment insurance overpayment collections must be both timelimited and limited to claimants where recovery is possible. Please call 1-800-772-1772 or your local field office and we may be able to process your waiver request quickly over the phone. SB 536 would provide a process for overpayments to be waived if a person can demonstrate financial hardship.
