Structure of the Workload Identifier

20 - Structure of the Workload Identifier (Rev. 47, 06-25-04) The CMS will assign the contractor workload identifier. It will consist of a combination of data to comprise a nine-digit alpha-numeric contractor workload identifier: • The first five characters will be a five-digit contractor number. • The next four characters represent the Business Segment Identifier (BSI) and consist of the following: o A two character contract jurisdiction code:  For fiscal intermediary, carrier and regional home health intermediary workloads, the code will be the official United States Postal Service (USPS) state abbreviation for the state jurisdiction.  For durable medical equipment regional carriers, these two positions will identify the DME region, for example Region A will be RA. o A one-character modifier to identify the type of Medicare FFS contract:  Fiscal intermediary = A  Carrier = B  Regional home health intermediary = R  Durable medical equipment regional carrier = D. o The final digit will be filled with a space. This structure recognizes that CMS considers there to be four different “types” of contractors, based on the types of claims they process for beneficiaries and providers in every state. The BSI distinguishes the customers in the geographic areas served and the type of claims administered: • For fiscal intermediaries – Providers in the state served plus any providers in other locations that nominated the FI to process its claims, and any chains (of providers) assigned to the FI. • For carriers and regional home health intermediaries – Providers in the state served. • For DMERCS – Suppliers serving beneficiaries that reside in the DMERC’s jurisdiction.
