This Statistical Brief presents data from the Healthcare Cost and Utilization Project (HCUP) on hospitalizations involving circumcision procedures in male newborns, updating previously published information from 2005. It provides details on characteristics of infants receiving circumcisions, complementing recently published data on trends in circumcision in the U.S. This Brief provides information on circumcision rates in hospitals across regions of the country by median income, by patient residence, and by payer. Findings by payer are of particular interest because it was recently reported that circumcision rates were 24 percent higher in hospitals located in states where Medicaid pays for circumcisions than in states where Medicaid does not pay for the procedure.
