The "Great American Healthcare Plan" significantly expands the utility and accessibility of Health Savings Accounts (HSAs). It proposes to increase contribution limitations, remove certain eligibility requirements, and allow funds to cover a broader array of expenses. These new eligible expenses include health insurance premiums, direct primary care arrangements, healthy food, vitamins, dietary supplements, and sports and fitness activities, subject to monthly limits based on account balance. The bill introduces greater flexibility by allowing medical expenses incurred before an HSA's establishment to be covered under certain conditions and permits administrative error corrections. It also enables HSA rollovers to children or parents of the account holder and grants HSAs equivalent bankruptcy protections as retirement funds. Employers would be able to satisfy their mandate by contributing $450 per month to an employee's HSA, and rollovers from Health Care Flexible Spending Accounts (FSAs) and Health Reimbursement Arrangements (HRAs) would be permitted. Furthermore, the legislation introduces "qualified general contributions" to HSAs from entities like non-profits or tribal governments, which would be excluded from gross income. It also allows charitable organizations to contribute up to $5,000 annually to an individual's HSA and permits HSA funds to be used for payments to health care sharing ministries. These provisions aim to broaden funding sources and eligible uses for HSAs. Title II of the bill establishes "health marketplace pools," which would be deemed employers under ERISA, allowing them to offer group health plans or group health insurance coverage. These pools must be formed for risk pooling, cannot discriminate based on health status, and can offer drug-only coverage. This aims to provide more options for individuals and small businesses to access group health benefits. A major focus of the bill is strengthening price transparency across the healthcare system. It mandates that hospitals publicly disclose all standard charges monthly, including gross charges, discounted cash prices, and payer-specific negotiated rates, in both machine-readable and consumer-friendly formats. Similar transparency requirements, with associated penalties for non-compliance, are extended to clinical diagnostic laboratories, imaging service providers, and ambulatory surgical centers, particularly those with hospital ownership. Health plans would be required to provide real-time, personalized cost-sharing information to enrollees via self-service tools, detailing deductibles, out-of-pocket maximums, and prior authorization requirements. Additionally, plans must publicly disclose machine-readable files containing in-network rates, historical net drug prices, and out-of-network billed/allowed amounts. The bill also strengthens group health plans' access to claims and encounter data from administrative service providers, prohibiting contractual limitations and imposing significant penalties for non-compliance. To further empower patients, the bill requires healthcare providers and facilities to furnish itemized bills within 30 days of final payment, detailing services, billing codes, prices, and charity care policies. It prohibits collection actions if these transparency rules are violated or if charges exceed good faith estimates without proper justification. Finally, the bill introduces a framework for "expanded-access prescription drugs" that can be dispensed by various licensed healthcare professionals, with federal preemption over conflicting state laws, and mandates coverage by Government-sponsored programs.
