If providers/suppliers meet the definition of a small provider/supplier, under the ASCA exceptions they are not required to submit claims electronically. It is possible that a small provider/supplier may receive a Request for Documentation letter from National Government Services to establish whether or not they meet the criteria for submission of paper claims. If a small provider/supplier receives a Request for Documentation letter from NGS, follow the instructions and complete a Waiver Request form within the timeframe given. NGS will then notify providers/suppliers by mail if they can continue to submit paper claims. If a small provider/supplier does not reply to the letter or follow the instructions within the time frame given, their paper claims will be denied.
