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.
