When patients lack sufficient health care insurance, financial matters beco
me integrally intertwined with biomedical considerations in the process of
clinical decision making. With a growing medically indigent population, cli
nicians may be compelled to bend billing or reimbursement rules, lower stan
dards, or turn patients away when they cannot afford the costs of care. Thi
s article focuses on 3 types of dilemmas that clinicians face when patients
cannot pay for needed medical services: (1) whether to refer the individua
l to a safety net provider, such as a public clinic; (2) whether to forgo i
ndicated tests and therapies because of cost; and (3) whether to reduce fee
s by fee waivers or other adjustments in billing. Clinicians' responses to
these dilemmas impact on quality of care, continuity, safety net providers,
and the liability risk of committing billing violations or offering nonsta
ndard care. Caring for the underinsured in the current health care climate
requires an understanding of billing regulations, a commitment to informed
consent, and a beneficent approach to finding individualized solutions to e
ach patient care/financial dilemma. To effect change, however, physicians m
ust address issues of social justice outside of the office through politica
l and social activism.
