A screening colonoscopy can turn into a diagnostic colonoscopy, For example; if during the screening, a polyp is found and removed, or any other diagnostic issue, it becomes a diagnostic colonoscopy.
Insurances could pay differently for screening colonoscopies than diagnostic colonoscopies. If you have a diagnostic colonoscopy, you may have more out of pocket expense, including lab and pathology charges.
Please check with your Insurance Plan. This will prepare you for what you may have to pay, if your procedure becomes diagnostic.
