Or search by name, organization, taxonomy, city, or state:

Search by	Example
NPI number	`1234567890`
Provider name	`Jane Smith`
Organization name	`Stormont Vail`
Taxonomy code	`207R00000X` (Internal Medicine)
City + State	`Topeka, KS`

What makes this different from NPPES

The NPPES NPI Registry gives you the provider record. RCI gives you the provider record plus the billing context:

NPPES gives you	RCI adds
Provider name, NPI, type	Facility CCN linkage
Practice address	GPCI values for that location
Taxonomy code	MAC jurisdiction
Organization affiliation	Payment system (OPPS/IPPS/MPFS)
Enumeration date	Billing form (CMS-1500 vs UB-04)
	Timely filing deadlines
	State Medicaid program
	Full L1-L6 resolution (with CPT)

Use cases

Who	Why
Billers	Look up a referring provider’s NPI, confirm taxonomy, get the billing context for their facility
Credentialing	Verify NPI status, check taxonomy against specialty
Payers	Validate provider identity and facility billing rules during adjudication
Revenue cycle	Cross-reference NPI → CCN → payment rules for claim routing
Platforms	Build provider search + billing context into your product
