National Provider Identifier (NPI)

• A 10-digit unique identification number that healthcare providers use to identify themselves in electronic health transactions.
• Mandated by the Health Insurance Portability and Accountability Act (HIPAA).
• Required for healthcare providers to participate in Medicare and Medicaid programs.

Patient Demographic (PD)

• Information about a patient's personal characteristics, such as name, address, date of birth, and gender.
• Collected to ensure accurate patient identification and facilitate communication between healthcare providers.
• Often used in conjunction with the NPI to create a patient-provider linkage for billing and record-keeping purposes.
