A screening colonoscopy is performed on an individual without symptoms, who has not been diagnosed with colorectal cancer or has no additional risk factors for colorectal cancer, such as polyps or inflammatory bowel disease, prior to the start of the screening exam. A diagnostic colonoscopy is performed on an individual who has symptoms, has a previous history of colorectal cancer, polyps or other gastrointestinal disease or disorders. Please be aware that the insurance companies must process claims based on the provider’s billing. If you have a preventive screening colonoscopy billed as a diagnostic exam instead, you should contact the provider’s office to discuss the services received and to ask if the claim can be resubmitted with preventive coding. If the provider’s office does not agree to resubmit the claim, you should contact the insurance carrier to request a review of the claim. It’s possible that claims originally billed as diagnostic may be reprocessed or adjusted to pay as preventive but only if it can be verified through the provider’s office that the exam started out as a preventive screening.
