Health plans and government programs regularly face difficult decisions about whether care is "medically necessary." NIHCM Foundation held a symposium, "Making Coverage Decisions about New and Emerging Technologies." Also, NIHCM co-sponsored a forum (policy brief) on this important topic with the U.S. Agency for Health Care Policy and Research (now the Agency for Healthcare Research and Quality). Papers commissioned for that event subsequently appeared in Health Affairs. For other medical necessity publications, see Quality Publications .
