Several databases available in Maryland are used to investigate whether Medicaid recipients are more likely than other persons to engage in medical malpractice litigation. All malpractice claims filed during 1985 and 1986 (N = 1037) were updated for outcomes through 1989 and described with regard to the payer status of claimants. The proportion of claims filed by persons enrolled in Medicaid before and/or during the alleged malpractice incident was lower than the proportion of state residents enrolled in Medicaid. In addition, the proportion of obstetric claims filed by Medicaid recipients was identical to their proportion of hospital discharges for obstetric services during the period in which the incidents occurred.
