An Act to prohibit cost sharing for opioid antagonists

This bill requires various health insurance plans in Massachusetts to cover opioid antagonists, such as naloxone, without charging patients any copay or coinsurance. It directly affects state employees, Medicaid participants, and individuals with private insurance policies issued within the state. The law allows these drugs to be covered under statewide standing orders, meaning a prescription from a doctor is not needed to receive the medication. The only exception to the no-cost rule is for plans governed by federal tax laws that would lose their tax-exempt status if they eliminated cost-sharing for this service.
