Noridian has seen an increase in undeliverable 1099s. To ensure all 1099s are received, Noridian is resending all 1099s with possible insufficient addresses. The remailing of 1099s will have included an enclosure with the following verbiage: "Enclosed is a duplicate of your 2016 Medicare 1099 originally mailed in January. There is concern that due to problems that occurred in the printing process some addresses were incomplete and undeliverable. We apologize for any inconvenience."
