Many healthcare-related statutes are lengthy and difficult to understand, but you can get a better idea of the meaning and intent behind a statute by looking at the various drafts of the bill, committee meetings, and hearings associated with its adoption. Luckily, most large pieces of legislation have legislative histories collected by Hein or ProQuest, so you can find all of the information about the legislation in one place.
