The bill amends Chapter 27-20.8 of the General Laws by introducing a new section that establishes a co-pay cap for prescription asthma inhalers, devices, and equipment. It mandates that health plans providing coverage for these items must limit the out-of-pocket expense for covered individuals to no more than twenty-five dollars ($25.00) for a thirty-day supply. Additionally, coverage for these items will not be subject to any deductibles.

The bill defines "prescription inhaler" as a prescribed inhaled medication approved by the FDA for the treatment or prevention of a respiratory condition, including but not limited to pressurized metered dose inhalers (pMDI), dry powdered inhalers (DPI), and soft mist inhalers (SMI). It specifies that "prescription devices and prescription equipment" refers to prescribed supplies used to administer inhaled medications, such as nebulizers and holding chambers.

Furthermore, the bill states that prior authorization policies may only be used to confirm the presence of diagnoses or other medical conditions that demonstrate medical necessity. The office of the health insurance commissioner is granted the authority to enforce compliance with these provisions and to promulgate rules and regulations necessary for implementation and alignment with federal requirements. The act is set to take effect on January 1, 2027.
