It is the intent of the legislature to ensure that all enrollees in managed care settings have access to adequate information regarding health care services covered by health carriers' health plans, and provided by health care providers and health care facilities. It is only through such disclosure that Washington state citizens can be fully informed as to the extent of health insurance coverage, availability of health care service options, and necessary treatment. With such information, citizens are able to make knowledgeable decisions regarding their health care.
