The main purpose of the Purchased and Referred Care Improvement Act of 2025 is to clarify and improve how costs associated with purchased or referred healthcare services are handled under the Indian Health Care Improvement Act. This legislation aims to protect patients from being held financially responsible for these costs and to streamline the reimbursement process for those who pay out-of-pocket for such services. Key provisions of the Act include significant changes to the liability for payment of purchased or referred care.
