John A. Hauser Mental Health in Aviation Act

Maddy summaryThis bill requires the Federal Aviation Administration (FAA) to update regulations to encourage pilots and air traffic controllers to seek and disclose mental health care without fear of losing their medical certification. It mandates an annual review of the "special issuance" process (for medical certification) to consider new treatments, improve examiner training, and reduce backlogs, while allocating $15 million annually (2026-2029) to recruit more medical examiners and provide mental health training. Additionally, it funds a $1.5 million annual public campaign to destigmatize mental health care in aviation, improve trust with workers, and make resources easily accessible at aviation medical offices and training facilities. The FAA must consult with industry stakeholders and report progress to Congress on implementation.

Indian Health Service Emergency Claims Parity Act

Maddy summaryThis bill amends the Indian Health Care Improvement Act to establish a 15-day notification deadline for Native Americans who receive emergency medical care from non-Indian Health Service providers or facilities. It directly affects Indigenous individuals seeking emergency treatment outside of IHS facilities by requiring them to notify the Service within 15 days to qualify for payment. The key provision replaces the previous time limitation with a standardized 15-day window for submitting claims. This change simplifies the reimbursement process for emergency care received under existing authority. The bill does not alter eligibility for care but streamlines the administrative requirement for claims processing.

The bill also updates the schedule for recouping federal funds, shifting the timeline for when insurers must repay taxpayer money to later dates ranging from 2029 to 2036.
