We examine whether patients covered by workers' compensation insurance
, which covers the cost of medical care for injured workers without co
st sharing and with relatively little oversight, are charged more for
treatment or receive more services than patients covered by traditiona
l insurance. Our findings indicate that workers compensation recipient
s are charged more for treatment. This difference persists in individu
al services - workers' compensation recipients are charged more per X-
ray and per examination than other patients. We consider different exp
lanations and argue that price discrimination probably plays a role.
