The Unique Identifier Rule established three types of identifiers to streamline healthcare transactions. The identifiers are:
1. National Provider Identifier (NPI): This identifier is a unique 10-digit number assigned to healthcare providers by the Centers for Medicare & Medicaid Services (CMS). It is used in standard transactions to identify healthcare providers.
2. National Health Plan Identifier (NHI): This identifier is used to uniquely identify health plans or insurers involved in healthcare transactions. It helps in streamlining administrative processes and ensuring accurate communication between different entities in the healthcare system.
The option that does not fit the list of Unique Identifiers provided is:
- Standard Unique Employer Identifier: This identifier is not part of the list of unique identifiers established by the Unique Identifier Rule. It is used to uniquely identify employers rather than healthcare providers, health plans, or administrative entities in the healthcare system.
