Frequently Asked Questions About the National Standard Employer Identifier (EIN). Who is required by HIPAA to use the EIN in electronic health transactions?


HIPAA does not require employers to use the standard employer identifier or standard health care transactions. However, we believe that many employers will want to take advantage of this standardization. Providers, health plans, and health care clearinghouses are required to use the standard employer identifier in electronic transactions, such as health care claims or eligibility inquiries, if the transactions require an employer identifier.
