Recent accounts of enrollees in managed care plans being denied access
to potentially lifesaving services have heightened public anxiety abo
ut the impact of managed care on the accessibility and appropriateness
of care, and this anxiety has been translated into legislative action
. The present review focuses on an area of managed care operations tha
t has received considerable attention in state legislatures and in Con
gress during the past 2 years: the financial relationship between mana
ged care health plans and physicians. Twelve states now mandate that m
anaged care plans disclose information about their financial relations
hip with physicians, and 11 states regulate the method used by managed
care health plans to compensate physicians. Most laws that regulate m
ethods of compensation prohibit health plans from providing physicians
an inducement to reduce or limit the delivery of ''medically necessar
y'' services. Moreover, in 1996 the Health Care Financing Administrati
on finalized its regulations governing the financial incentives facing
physicians in plans that treat Medicaid or Medicare patients, and the
se regulations went into effect on January 1, 1997. These regulations
also are examined in this study.
