what is the g code for a medicare colonoscopy?
For patients at high risk for colorectal cancer, a screening barium enema performed as an alternative to colonoscopy (G0105) is reported with code G0120. Medicare will pay for this procedure every two years (at least 23 completed months since the last screening barium enema or colonoscopy). There is no age limit. For patients at normal risk for colorectal cancer, a screening barium enema performed as an alternative to sigmoidoscopy (G0104) is reported with code G0106.
