Transparency in Billing Act of 2023

This bill requires hospitals to include a specific unique identifier for off-campus outpatient departments when billing group health plans or insurance issuers for services provided there. It directly affects hospitals that operate off-campus clinics and health insurers that process these claims. The key provision mandates that claims must include this department-specific identifier to prevent hospitals from misrepresenting where services were delivered. The requirement takes effect for plan years beginning January 1, 2024.
