Note: This article was revised on November 9, 2006, to reflect changes made to CR5243. CR5243 was revised to include a more complete definition for the 2000A. The article was also revised to reflect the new CR transmittal number, CR release date, and the Web address for accessing CR5243. All other information remains the same. |
Provider Types Affected
Institutional providers who bill Medicare fiscal intermediaries (FI) for their services
Provider Action Needed
Impact to You
Effective January 1, 2007, institutional Medicare providers who submit claims for their primary facility and its subparts (such as psychiatric unit, rehabilitation unit, etc.) must report a taxonomy code on all claims submitted to their FI.
What You Need to Know
Please use the attachment to CR5243 (supplied in the Background section of this article) to crosswalk the OSCAR (Online Survey Certification and Reporting System) number to the appropriate taxonomy code for your type of facility. The taxonomy code will assist Medicare in crosswalking from the national provider identifier (NPI) of the provider to each of its subparts in the event that the provider chooses not to apply for a unique NPI for each of its subparts individually.
What You Need to Do
Refer to the Background section of this article for additional crosswalk information .
Background
Regulations implementing the Administrative Simplification provisions of the Health Insurance Portability and Accountability Act (HIPAA) of 1996 require the use of National Provider Identifiers (NPIs) by covered health care providers and health plans (other than small plans) effective May 23, 2007. (45 CFR Part 162, Subpart D (162.402-162.414)
The Centers for Medicare & Medicaid Services (CMS) will utilize a Medicare Provider Identifier Crosswalk between NPIs and legacy identifiers (such as OSCAR numbers) to validate NPIs received in transactions, assist with the population of NPIs in Medicare data center provider files, and to report NPIs on remittance advice (RA) and coordination of benefit (COB) transactions. (See MM4023 at the link provided below for more information on CMS’s implementation of the NPI.) The crosswalk detailed in CR5243 between the provider’s OSCAR number and the appropriate taxonomy code will assist in this process.

Be sure to follow the billing instructions contained in CR5243:
- Report the service facility locator loop (2310E) in an 837-I claim whenever the service was furnished at an address other than the address reported on the claim for the billing or pay-to provider.
- Input the taxonomy code in the 837-I provider loop 2000A (billing or pay-to-provider taxonomy code, but do not report taxonomy in this loop if there is no data reported in the service facility locator loop of the claim).
- Submit separate batches of claims for each subpart identified by a different taxonomy code.
- Providers submitting claims for their primary facility and its subparts must submit a nine-digit zip code on their claims.
- CMS recommends submitting both the OSCAR number and the NPI on claims submitted through May 22, 2007. (Note that failure to report an OSCAR number that corresponds to your NPI could result in a payment delay.)
Implementation Date
The implementation date for this instruction is January 2, 2007.
