Stanislaus Surgical Hospital said Monday it will suspend operations indefinitely and lay off employees, due to a federal agency decision not to renew its provider agreement for serving Medicare and Medi-Cal patients. The temporary closure of the 23-bed hospital at Oakdale Road and Orangeburg Avenue is effective Saturday, a spokesperson said in a statement Monday. The CMS is terminating the provider agreement with Stanislaus Surgical effective Sept. 15 because the hospital is not in compliance with conditions of participation in the programs.
