Has PQRS paid off more than you expected? You might have accidentally been double-paid. Part B MAC National Government Services announced on Oct. 6 that it erroneously sent duplicate PQRS payments to providers in Connecticut and New York for payments processed on Sept. 7. If you received a double payment from this carrier, you don't need to do anything about it, NGS Medicare said in its statement. The MAC "will be requesting refunds of this money in the near future," it noted.
