This bill establishes new transparency requirements for health carriers in New Hampshire, mandating that they disclose detailed cost information about healthcare services and prescription drugs through publicly accessible machine-readable files. Specifically, health carriers must create and monthly update three types of digital files: an in-network rate file (showing negotiated rates for services), an out-of-network allowed amount file (displaying costs for services from providers outside their network), and a prescription drug file (revealing negotiated rates and historical net prices for medications). These files must include specific details like billing codes, provider identifiers, and dollar amounts, and must be available online for free without requiring user accounts or credentials. The files aim to help consumers and researchers understand healthcare pricing by providing standardized, comprehensive cost information. Key definitions are established for terms like “billed charge,” “negotiated rate,” and “historical net price,” ensuring clarity in reporting. The requirements will apply to health benefit plans beginning January 1, 2026, and include provisions for good-faith compliance, allowing carriers to correct errors and rely on information from other sources. The bill’s goal is to increase transparency in healthcare costs and facilitate easier comparison of pricing across different health carriers.
