People that may benefit from checking blood glucose include those: 1  taking insulina hormone that helps the body use glucose for energy. 2  that are pregnant. 3  having a hard time controlling blood glucose levels. 4  having low blood glucose levels. 5  having low blood glucose levels without the usual warning signs. 6  have ketones from high blood glucose levels.
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.
Colonoscopy is a good example. There are a series of colonoscopy codes, starting with the base code 45378. CMS has developed a set of G codes for screening tests, in the range of G0104âG0106, and G0120âG0122.
