On July 24, the Massachusetts House unanimously advanced a health care package that includes a provision banning copay accumulators in the state. Since the House amended the bill, which previously passed the Senate in November, a conference committee has been established to resolve the differences between the two versions. The Association for Clinical Oncology and the Massachusetts Society of Clinical Oncology joined a coalition letter urging members of the conference committee and House and Senate leadership to retain the copay accumulator language in the final version.
