Background: Health insurance fraud committed by patients may be an inc
reasing problem given the number of underinsured and uninsured people
in the United States. Physicians recognizing acts of health insurance
fraud perpetrated by patients face an ethical dilemma: should they dis
close the incident to the insurance company, or protect patient confid
entiality? Objective: To explore physicians' attitudes toward the repo
rting of patient-initiated health insurance fraud. Methods: Three hund
red seven physician members of the American College of Physicians retu
rned a mailed questionnaire that presented 6 case vignettes (3 variabl
es) of patients who used a relative's insurance to obtain health care
in the past. For each vignette, respondents were asked whether the tre
ating physician should report insurance fraud to the health insurance
carrier. Results: Sixty-three respondents (20.7%) indicated that physi
cians should report all the patients presented in the vignettes, while
45 (14.8%) indicated none should be reported; the rest indicated that
the decisions to report should be based on the characteristics presen
ted, with acute vs terminal illness (P<.001), history of fraud (P<.001
), and wealth of the patient (P<.001) all causing physicians to be mor
e likely to report the patient to the health insurance carrier. Multiv
ariate analysis demonstrated that type of practice (P=.04) and respond
ents' experiences with insurance fraud (P=.03) had significant effects
on the willingness to report patients. Conclusions: Physicians are di
vided about whether to report patients who have committed insurance fr
aud. Their decisions to report insurance fraud are influenced by their
attitudes and demographic features, as well as by patient factors.
