Most US insurance has very strict guidelines about what is diagnostic vs preventative for a colonoscopy. And its almost certianly diagnostic.

diagnostic does not mean "not covered", it just means it moves out of the "zero cost even if you haven't met your deductible yet" categroy defined by the ACA, and into the regular category where you pay your deductible, copays and coinsurance
