Does Medicare Pay For A Colonoscopy?

  • Medicare with Melissa

Colorectal cancer is the third leading cause of cancer-related deaths in the United States. Colonoscopies are important screenings that help in the early detection and prevention of colorectal cancer, especially as we get older. But does Medicare pay for a colonoscopy? Keep reading to discover more about colonoscopies, including the appropriate age for screening based on your risk profile and how different Medicare plans handle coverage for this procedure.

What is a Colonoscopy?

A colonoscopy is a diagnostic procedure that enables a gastroenterologist to closely examine the inner lining of your large intestine (rectum and colon). The procedure uses a flexible, slender tube called a colonoscope that is gently inserted into the rectum and guided through the colon. A small video camera attached at the end of the colonoscope sends real-time images to a monitor, providing a detailed view. The procedure usually takes around 30 minutes to an hour.

During the colonoscopy, your doctor can detect inflamed tissue, ulcers, polyps (small growths that could potentially turn into cancer), and any abnormality in the colon. The colonoscope also allows for the removal of polyps and some cancers in the colon at the same time they are discovered, a process known as a polypectomy.

One additional benefit of a colonoscopy is that it allows your doctor to obtain biopsy samples while performing the procedure. In case any suspicious areas are detected, a small amount of tissue can be removed and sent to a laboratory for in-depth examination. This approach enables the identification and proper treatment of diseases, including early-stage cancer and precancerous growths.

A colonoscopy is not only a diagnostic tool but also a preventative one. Regular colonoscopies can help detect colorectal cancer in its early stages, significantly increasing the chances of successful treatment. In many cases, a colonoscopy can prevent colorectal cancer entirely by finding and removing polyps before they have a chance to develop into cancer.

When should I get screened?

The timing of your first colonoscopy and the frequency of subsequent screenings depends on a variety of factors, including your age, medical history, family history of colorectal cancer, and overall health status.

Age-Based Recommendations

If you’re at average risk, most medical experts usually follow the guidelines provided by the American Cancer Society and recommend beginning regular colonoscopies at age 45. Prior to this change in 2018, the recommended starting age was 50. The reason for this shift was the rising incidence of colorectal cancer among younger adults.

If your colonoscopy results are normal and you don’t have other risk factors, your doctor will likely recommend that you have the procedure again in 10 years.

High-Risk Individuals

Certain people may need to start screenings earlier and have them more frequently. High-risk individuals include those with:

  • A personal history of colorectal cancer or certain types of polyps.
  • A family history of colorectal cancer or polyps, particularly if a first-degree relative (parent, sibling, or child) was diagnosed with the disease before the age of 60.
  • A known family history of hereditary colorectal cancer syndromes, such as familial adenomatous polyposis (FAP) or Lynch syndrome (hereditary non-polyposis colorectal cancer or HNPCC).
  • A personal history of inflammatory bowel disease (IBD), including Crohn’s disease or ulcerative colitis.

If you fall into any of these high-risk categories, you should talk to your doctor about when to begin screenings and how often they should be repeated.

Remember, colorectal cancer doesn’t always present symptoms in its early stages, which is why regular screenings are so crucial. When caught early, the chances of successfully treating colorectal cancer are much higher, and colonoscopies play a crucial role in that early detection.

Medicare Colonoscopy Coverage

If you’re identified as high-risk for colorectal cancer, Medicare covers colonoscopy screenings every 2 years. This allows for frequent monitoring and early detection of potential issues. Being classified as high risk can depend on several factors, including personal and family medical history, age, lifestyle choices, and certain genetic conditions.

If you’re not considered high-risk, Medicare offers coverage for a colonoscopy once every 10 years, or once every 2 years if you’ve previously undergone a flexible sigmoidoscopy.

Medicare coverage also extends to situations where you’ve initially undertaken a non-invasive stool-based screening test, like fecal occult blood tests or a multi-target stool DNA test. If the results of these tests are positive, Medicare covers a follow-up colonoscopy as a screening test.

So, how much does a colonoscopy cost with Medicare? If your doctor or healthcare provider agrees to accept the Medicare-approved amount as full payment for services (known as accepting assignment), you won’t have to pay anything for the screening test. However, if a polyp or other tissue is detected and removed during the colonoscopy, you’ll be responsible for paying 15% of the Medicare-approved amount for the doctors’ services.

Additionally, if the procedure takes place in a hospital outpatient setting or an ambulatory surgical center, a 15% coinsurance fee will also apply for the facility. The good news is that the Part B deductible does not apply in any of these situations.

As with any medical procedure, it’s advisable to discuss the cost and coverage details with your healthcare provider. The exact amount you owe may vary based on multiple factors. These can include other insurance you may have, the fees your doctor charges, whether your doctor accepts assignment, the type of facility where you have your procedure, and the location where you receive your test or service.

Medicare Advantage Colonoscopy Coverage

Medicare Advantage, also known as Medicare Part C, is a type of health insurance plan provided by private insurance companies approved by Medicare. These plans must offer at least the same level of coverage as Original Medicare (Part A and Part B), which means that coverage for colonoscopies is included. However, the specifics of this coverage can vary based on the individual Medicare Advantage plan.

If you’re enrolled in a Medicare Advantage plan, you can expect coverage for colonoscopy screenings in line with the Medicare guidelines. That means, if you are deemed high risk for colorectal cancer, colonoscopy screenings will be covered once every 24 months. If you’re not considered high risk, the screenings are typically covered once every 120 months, or every 48 months if you have previously had a flexible sigmoidoscopy.

Like Original Medicare, if your initial screening was a non-invasive stool-based test and you received a positive result, a follow-up colonoscopy is also covered as a screening test under Medicare Advantage.

However, it’s important to remember that each Medicare Advantage plan can set its own out-of-pocket costs. This means that the specifics of your copayments, deductibles, or coinsurance can vary based on the plan you choose. Some plans might require you to pay a copayment for your colonoscopy, while others might apply the procedure towards your plan’s annual deductible. Still, others may have different rules about coverage if the colonoscopy is performed as a screening test versus a diagnostic procedure.

Furthermore, Medicare Advantage plans often have networks of preferred providers. Depending on your plan, you might need to choose a doctor within the plan’s network, or you could face higher costs. In some cases, the procedure might not be covered at all if it’s performed by a doctor outside of your plan’s network.

To get the most accurate information, it’s highly recommended that you contact your plan provider directly. Ask about any potential out-of-pocket costs you might be responsible for, whether you need to choose a provider from within your plan’s network, and what conditions apply if the screening becomes a diagnostic procedure.

Medicare Supplement Colonoscopy Coverage

Medicare Supplement Insurance, also known as Medigap, plays a vital role in handling the out-of-pocket costs that aren’t covered by Original Medicare. These costs include deductibles, copayments, and coinsurance. Understanding how your Medigap policy works with your Original Medicare coverage, especially when it comes to colonoscopy screenings, can give you a clear financial picture and peace of mind.

If you’re enrolled in Original Medicare and have a Medigap policy, Medicare first pays its share of the approved amount for your colonoscopy. After this, your Medigap policy kicks in to cover some or all of the remaining costs, depending on the specific policy you have.

For instance, if a polyp or tissue is found and removed during your colonoscopy, Original Medicare covers 80% of the Medicare-approved amount for your doctor’s services. The remaining 20% and any coinsurance fees for the hospital outpatient setting or ambulatory surgical center could potentially fall on you. However, with a Medigap policy, these remaining costs are likely to be covered, reducing or even eliminating your out-of-pocket expenses.

It’s crucial to remember that the degree of coverage offered by your Medigap policy can vary depending on the specific plan you have. Medigap plans are standardized and named by letters (A, B, C, D, F, G, K, L, M, and N) with each offering different levels of coverage. Plans F and G, for instance, cover all the coinsurance and copayment costs left after Original Medicare has paid its share.

However, you must also be aware of potential restrictions. Medigap policies generally don’t cover any healthcare provider who doesn’t accept Medicare. This is why it’s always advisable to confirm with your healthcare provider about their participation in Medicare before scheduling your colonoscopy.


Preventive screenings like colonoscopies play a crucial role in maintaining your health, especially as you age. With the knowledge you now have about your coverage, you can confidently schedule your screening, knowing that your Medicare plan will support you.

Remember, early detection through regular screenings is one of the most effective ways to prevent colorectal cancer. So, stay proactive about your health and be sure to use the benefits that your Medicare plan offers. That way you can live a long and healthy life with peace of mind.

Meet Melissa MacCalla

Medicare is not simple and can be hard, frustrating, and downright confusing for most. I love when I get someone on the phone and I am given the opportunity to explain the difference in plans to them and have Medicare make sense. I enjoy talking to clients year after year, hearing about their families growing or them asking about mine.


Oh my gosh!! I was so confused about the Medicare Supplement process. I am turning 65 soon and am retired and have always had insurance thru my former employer. I didn’t know a thing about going on Medicare and was struggling to sort it all out.

A friend of mine recommended contacting Senior HealthCare Solutions, so I did. Melissa was FANTASTIC!! She was professional, responsive, caring and friendly. She explained the steps I needed to take, gathered my information, helped me choose good plans for MY specific needs and took care of my applications over the phone. 1-2-3, eesy-peesy and I was done!! And it didn’t cost me a DIME!!! WOW!!! I HIGHLY recommend Senior Healthcare Solutions for anyone who’s overwhelmed with making the right choices with Medicare Supplemental Insurance and Rx coverage. It’ll take a load off your mind!
