HIPAA Title II focuses on standardizing healthcare transactions and protecting private health information. It requires covered entities to use electronic transactions by October 2002 and comply with unique identifiers rules. These unique identifiers include an employer ID, National Provider Identifier (NPI), and proposed National Health Plan Identifier (NHI). The Privacy Rule aims to properly protect individuals' health information while allowing needed information sharing. It balances privacy protections with important data uses. The Security Rule ensures electronic protected health information is only available to authorized persons and maintains integrity and availability of the data.
