What Is an NPI?
An NPI is a 10-digit numeric identifier. It does not carry information about you, such as the State where you practice, your provider type, or your specialization. Your NPI will not change, even if your name, address, taxonomy, or other information changes.
In HIPAA standard transactions, the NPI must be used in place of other provider identifiers, such as a Provider Transaction Access Number (PTAN), Online Survey Certification & Reporting (OSCAR), and National Supplier Clearinghouse (NSC).
Benefits of an NPI
Benefits of an NPI include:
- Simple electronic transmission of HIPAA standard transactions
- Standard unique health identifiers for health care providers, health care plans, and employers
- Efficient coordination of benefit transactions
What an NPI Doesn’t Do
Obtaining an NPI will not:
- Change or replace your current Medicare enrollment or certification process
- Enroll you in a health plan
- Ensure you are licensed or credentialed
- Guarantee payment by a health plan
- Require you to conduct HIPAA transactions
