The Maine HealthCost website is maintained by the Maine Health Data Organization, an independent executive agency established by the Maine legislature in 1996 "to collect clinical and financial health care information and to exercise responsible stewardship in making this information accessible to the public." The site is one of only two state-mandated transparency websites nationwide that received a grade of "B" from Price Transparency Task Force members Catalyst for Payment Reform and Health Care Incentives Improvement Institute in their 2014 Report Card on State Transparency Laws. (The other state receiving a "B" grade, the highest grade awarded in the 2014 report, was Massachusetts). 

The site is recommended in part because it provides data on actual paid amounts for a variety of procedures and services. The "Cost Compare" function on the site allows comparison of average prices for procedures at different facilities in the state. The site’s resources page also provides links to cost calculators that health plans offer for their subscribers in Maine.
