A colonoscopy is a colon cancer screening procedure that allows your doctor to examine the lining of your large intestine, or colon. It’s a way to check for colon polyps, ulcers, tumors and other early signs of colon cancer or colorectal cancer.
Colonoscopies are essential because they can help your doctor find and treat colorectal cancers in their earliest stages. The earlier colon cancer is found, the better the prognosis. That makes a colonoscopy one of the most effective ways to test for colon cancer and protect your health and life.
During a colonoscopy:
Beginning at age 50, colonoscopies are recommended as a screening for colorectal cancer. A colonoscopy may also be recommended for abdominal pain, chronic constipation, chronic diarrhea and rectal bleeding.

Colonoscopy prep requires you to empty your colon completely. Starting 12 to 24 hours before your exam, you may be required to avoid solid foods and colored liquids. Your doctor may also ask you to fast completely the night before your exam.
In preparation for your colonoscopy, you may need to take a laxative, perform an at-home enema or make adjustments to any medications you’re taking.
Since everyone is different, be sure to ask your doctor how to best prepare for your colonoscopy.
On the day of your colonoscopy appointment, you’ll be given sedation medication through an IV so you feel relaxed and fall asleep while your doctor examines your large intestine (colon). This medication will be delivered through a needle in your arm (IV).
During the colonoscopy:
During a virtual colonoscopy (CT colonography), your doctor will perform CT scans to produce pictures of your colon. You’ll lie on your back and your stomach so your doctor can get images from different angles. These scans are then reviewed to check for colon polyps and other abnormalities.
Both a colonoscopy and a virtual colonoscopy each take about 30 minutes to complete. Recovery time is usually about an hour.
After a colonoscopy, it can take up to an hour for the sedative to begin to wear off, and up to a day for the effects of the sedative to disappear completely. You’ll spend the initial recovery time in a recovery room at the clinic or hospital.
When you wake up, your doctor will give you instructions for what to do when you get home. You may have some mild cramping or pass some air.
Because of the sedative, you won’t be able to drive or work after the colonoscopy, and will need to arrange for a ride home. You should be able to return to normal activity the following day.
Colonoscopy results can be:
If you’re 50 or older, your doctor will probably want you to have colonoscopies regularly – this is the most common colonoscopy age to begin getting screened.
If you’re younger, and any of the following colon cancer risk factors apply, your doctor may suggest you start early colonoscopy screenings:
Ask your doctor when you should start getting screened and how often you should have a colonoscopy.
Colon cancer grows slowly and doesn’t always cause symptoms in the early stages. But as it progresses, it can cause:
If you notice any of these warning signs, call your colonoscopy doctor (gastroenterologist) or ask your primary care doctor for a referral.
When a colonoscopy is performed, it’s categorized as either a “screening” or “diagnostic” colonoscopy. Your current symptoms, family history and personal health history will determine how your doctor categorizes your colonoscopy.
Both screening and diagnostic colonoscopies are classified using national guidelines. These guidelines are used by insurance companies to determine the amount of colonoscopy costs they will cover and what your out-of-pocket expenses will be.
Whether your colonoscopy is for screening purposes or diagnostic purposes, biopsies and lab testing could influence the overall cost of the procedure.
If a polyp or mass is found and sent to a Pathology lab for evaluation, the overall cost of the colonoscopy will be more expensive than if no mass is found. Mass removal and testing can occur during both screening and diagnostic colonoscopies.
Cost of Screening Colonoscopies
Screening colonoscopies are preventive in nature and are used to check for signs of cancer. Most insurance companies will cover the cost of screening colonoscopies beginning at age 50 and then every 10 years thereafter.
If you have a family history of colon cancer, your doctor may order a screening colonoscopy before age 50.
If screening colonoscopies are covered by your insurance plan, there is usually little (if any) out-of-pocket cost to you.
Cost of Diagnostic Colonoscopies
There are 2 reasons a colonoscopy could be considered “diagnostic” in nature:
Many insurance plans cover diagnostic colonoscopies, however the procedure is not considered “preventive.” Because of this, you may be responsible for a co-payment, and may incur out-of-pocket expenses that count toward your deductible.
In some cases, your colonoscopy could be categorized as diagnostic by the hospital and as a screening by your doctor’s office. This is due to national coding guidelines, which cannot be changed. If your colonoscopy is performed in a doctor’s office, it will be categorized as either screening or diagnostic, not both.
