Screening Colonoscopy Versus Diagnostic Colonoscopy
Patient is over 45 and asymptomatic with no GI issues to report.
- No pathology found to report. IF screening colonoscopy is a benefit, insurance should consider it as a covered benefit.
- If pathology is found and reported, a modifier is added to the claim to demonstrate it was a screening procedure which changed to a diagnostic one, which changes patient responsibility for payment.
Patient of any age with any GI symptoms or a positive Cologuard or fecal occult test.
- GI symptoms disqualify any colonoscopy from being a “screening” procedure, even if it is the first procedure a patient has had or they are due for repeat. Examples include diverticulitis, rectal bleeding, abdominal pain, abnormal imaging, etc.
- Most insurance companies consider Cologuard to be the primary colon cancer screening test if done first. If test result is positive, colonoscopy can only be diagnostic.
- Colonoscopy may be a covered benefit, but diagnostic colonoscopy is not considered “screening” or preventative care.
