When any provider in the DO’s service area has been authorized to make charges for excess costs, the DO must be alert to the possibility of complaints from beneficiaries regarding these charges for covered services. Notice having been given to the public and to the beneficiary concerning the provider’s right to charge (see HI 00601.600 ), the DO should be able to explain the basis for the charges. To assist the DO, the CMS RO issues lists of providers authorized to make specified charges and updates these lists periodically.
