The main purpose of the Maximizing Opioid Recovery Emergency Savings Act, also known as the MORE Savings Act, is to improve access to effective treatments for opioid use disorders under the Medicare program. It aims to eliminate out-of-pocket costs for certain opioid treatments, making them more affordable for individuals in need. Key provisions of the Act include the requirement for Medicare and health insurance plans to cover medication-assisted treatments for opioid use disorders, medications to reverse opioid overdoses, and various recovery support services.
