The bill would allow Medicaid to again cover circumcisions. The procedure was dropped from Medicaid last year as a money-saving move. Several states have stopped covering circumcisions amid concerns that they're not medically necessary. Colorado projected that it would save about $186,500 a year if it stopped covering circumcisions.

Colorado's bill was proposed Thursday by several Democrats. It awaits a hearing in the Senate.

Seventeen other states have dropped coverage for routine circumcisions under Medicaid.

Circumcision is the most common medical procedure performed on children in the United States, but is far less common around the world. According to data from the World Health Organization, 75 percent of men in the U.S. have been circumcised compared with 30 percent in Canada and 6 percent in the United Kingdom.
