FI Jurisdiction of Requests for Payment (Rev. 1, 10-01-03)

The FIs have jurisdiction for the following:

• All Part A services (hospital, SNF, HHA, and hospice);

• Most Part B services from providers that furnish Part A services; and

• Part B facility services from CORFs, Renal; Dialysis Facilities, Rural Health Clinics, Religious Nonmedical Institutions, Outpatient Physical Therapy Centers, Federally Qualified Health Centers, and Community Mental Health Centers. For example, rural health clinics may bill physician services to carriers under applicable physician provider numbers on carrier-compliant claim formats. Also, some DMEPOS may be billed by home health agencies on claims sent to RHHIs, and some physician, lab and ambulance services may be billed by some types of providers submitting claims to FIs.

Within this general framework, specific jurisdiction among FIs is determined by which FI has received the official tie-in notice from the CMS RO. See §20 for procedures for provider nomination of its FI. Once an FI is assigned, that FI has jurisdiction for all services furnished by the provider or supplier, except those service outside the provider/suppliers scope of service. See the Medicare Claims Processing Manual chapters relating to the service for a description of who may bill the individual service, e.g. lab (Chapter 17) or DME (Chapter 20).

The RHHIs have jurisdiction for HHA and Hospice claims.

There is a national single FI for FQHCs. United Government Systems processes all claims from independent FQHCs.

Regional RHC FIs have jurisdiction for claims from freestanding RHCs. See for a listing of RHC regional FIs. The host provider’s area FI has jurisdiction for provider based RHCs and FQHCs.

In addition some provider chains may elect a single FI for all providers in the chain. A complete list of FIs and carriers and their service areas may be viewed at:

Note that some providers and supplier under FI claims jurisdiction may also provide covered services outside the scope of the facility service, and may bill these services to the carrier.

Claims sent to the incorrect FI are returned to the provider with an instruction to bill the correct FI.
