The Impact of Premium Changes on CommonHealth-Working Enrollment

In 2003, Massachusetts substantially increased premiums charged to enrollees in its CommonHealth-Working (CH-W) program. This study evaluates the impact of the premium change on enrollment. Findings indicate the premium increase had a small, but statistically significant impact on program exits. Key factors as to why the CH-W experience differs from other state programs experiencing similar enrollment declines are discussed. A report and presentation of the study are included.
