This article analyzes disease‐specific moral hazard effects in the demand for physician office visits and explores whether optimal insurance for physician services should be designed to have disease‐specific cost sharing. Generalized method of moments is implemented to address the endogeneity of private health insurance, and the nonnegativity and the discreteness of physician services use. The results indicate that the moral hazard effect varies considerably across disease‐specific specialist care. The strongest moral hazard (for no‐condition related specialist visits) is almost twice the moral hazard effect of the weakest (for chronic condition related specialist visits). Although the findings indicate some variation in the moral hazard effect across disease‐specific general practitioner visits, the variation is less considerable. The main policy implication is that optimal insurance for physician services should be designed to have differential cost sharing based on disease status rather than to have uniform cost sharing.
