This article examines the ethics of medical practice under managed car
e from a pragmatic perspective that gives physicians more useful guida
nce than do existing ethical statements. The article begins with a fra
mework for constructing a realistic set of ethical principles, namely,
that medical ethics derives from physicians' role as healers; that et
hical statements are primarily aspirational, not regulatory; and that
preserving patient trust is the primary objective. The following concr
ete ethical guidelines are presented: Financial incentives should infl
uence physicians to maximize the health of the group of patients under
their care; physicians should not enter into incentive arrangements t
hat they are embarrassed to describe accurately to their patients; phy
sicians should treat each patient impartially without regard to source
of payment, consistent with the physician's own treatment style; if p
hysicians depart from this ideal, they should inform their patients ho
nestly; and it is desirable, although not mandatory, to differentiate
medical treatment recommendations from insurance coverage decisions by
clearly assigning authority over these different roles and by physici
ans advocating for recommended treatment that is not covered.
