H.R. 8324, the Great American Healthcare Plan, makes significant changes to health savings accounts and requires sweeping price transparency across the healthcare system. The bill increases HSA contribution limits to match 401(k) limits (currently $23,500 annually, adjusted for inflation) with catch-up provisions for those age 50 and older, expands HSA inheritance to allow transfers to children and grandparents, and permits charitable organizations to contribute up to $5,000 annually to individuals' accounts. The legislation requires hospitals, diagnostic laboratories, imaging centers, and ambulatory surgical centers to publicly disclose detailed pricing information in machine-readable formats starting in 2027 and 2028, while health insurance plans must provide real-time access to individual cost estimates and publicly release monthly negotiated rate data; these providers face civil penalties up to $300 per day for non-compliance. The bill also mandates that healthcare providers deliver itemized bills within 30 days, requires health plans to provide detailed explanations of benefits within 45 days, and gives group health plans expanded access to claims and pricing data from providers and service administrators within 15 days. Additionally, the legislation establishes a rebate system for certain Medicare Part B drugs when negotiated prices fall below standard rates and ensures government health programs cover expanded-access prescription drugs administered by qualified healthcare professionals.
