How Will My Colonoscopy Be Covered if I Have Medicare And Humana Choice PPO? 
Colonoscopy can be covered as a preventative benefit under the Humana plan if it is a routine procedure . If it is part of the regular preventative schedule there will be no cost to have it done . The trick however is that if anything is discovered or if a polyp is removed , it will no longer be billed as a preventative procedure and there will be a copy as a result . Most of the time it is billed as an outpatient surgery and you would need to pay the cost share applicable to it . A diagnostic Colonoscopy is going to be billed as an outpatient surgery .
