State lawmakers have sent along to Gov. Charlie Baker a bill that would limit the practice of “step therapy,” which, critics say, steers patients towards cheaper medication options, rather than ones they require.

The legislation is aimed at making sure that health care providers can implement an effective treatment plan for patients without a medical insurance provider insisting on another option.

“This marks an important step today in guaranteeing that those seeking medical treatment throughout the Commonwealth will have fewer barriers to accessing the best treatment available to them,” state Sen. Nick Collins, who represents Dorchester and South Boston, said in a statement.

“I am sure,” he added, “that the positive effects of this legislation will be felt throughout the state, and the First Suffolk District particularly so. I represent a diverse district with a wide range of needs, and we will continue working to ensure that the health and wellbeing of our constituents continues to improve.”

The legislation first passed in July before the enactment vote this week.
