MassHealth Regulations DisclaimerThe regulations that are available through the links below appear in a format created for providers. The regulations have been modified from the Secretary of State's official version of the Code of Massachusetts Regulation (CMR) to add a header on every page. Although we try to keep the regulations on our site up-to-date, it is not always possible. IN the case of any discrepancy between the version on this site and the official CMR published by the Secretary of state, the Secretary of State's version takes precedence.
