Yes, Medicare covers colonoscopy after age 75, but screening stops being routine

Medicare Part B pays for colonoscopy after age 75, but the coverage rules change. Once you turn 75, Medicare no longer covers routine screening colonoscopies — the kind you get when you have no symptoms and no personal or family history of colorectal cancer. If you have symptoms, a personal history of polyps, or a family history of colorectal cancer, Medicare will still cover a diagnostic colonoscopy at any age.

The shift happens because the U.S. Preventive Services Task Force recommends stopping routine screening at age 75 unless you have specific risk factors. Medicare follows this guidance. If your doctor thinks a colonoscopy is medically necessary for you personally — because of symptoms, prior findings, or risk — Medicare covers it. The difference is whether the procedure is preventive or diagnostic.

Key Takeaways

  • Medicare covers colonoscopy after 75 only if it is diagnostic (you have symptoms or a history of polyps) rather than routine screening.
  • If you had a normal colonoscopy before age 75, you do not need another one after 75 unless symptoms develop.
  • Your doctor must document a medical reason for the procedure — symptoms, prior polyps, or family history — for Medicare to cover it.
  • You pay 20 percent of the cost after your Part B deductible, unless your doctor finds and removes polyps during the procedure.

The difference between screening and diagnostic colonoscopy

A screening colonoscopy is done on people with no symptoms to look for cancer or polyps before they cause problems. A diagnostic colonoscopy is done because you have symptoms (bleeding, changes in bowel habits, abdominal pain) or a history that suggests you need one (prior polyps, family history of colorectal cancer, or inflammatory bowel disease).

Medicare covers diagnostic colonoscopy at any age, including after 75. It does not cover routine screening after 75. If your doctor performs a screening colonoscopy after 75 and finds and removes a polyp, Medicare may reclassify it as diagnostic and cover it, but you should not count on this. The safest approach is to have your doctor document the medical reason before the procedure.

What Medicare pays and what you pay

If Medicare covers your colonoscopy, you pay 20 percent of the Medicare-approved amount after you have met your Part B deductible for the year. The deductible for 2024 is $240, though this amount changes yearly. If the procedure is done in a hospital outpatient department rather than an office or surgery center, you may owe a copay instead of coinsurance, and the amount varies.

If your doctor finds and removes polyps during a diagnostic colonoscopy, the procedure is covered in full after your deductible — you pay nothing for the removal itself. If the colonoscopy is classified as screening and Medicare denies it, you become responsible for the full bill unless you signed an Advance Beneficiary Notice (ABN) before the procedure. An ABN tells you in advance that Medicare may not cover the service, and you agree to pay if it does not.

When your doctor might recommend colonoscopy after 75

Even though routine screening stops at 75, your doctor may recommend a colonoscopy if you have symptoms like rectal bleeding, persistent changes in bowel habits, unexplained anemia, or abdominal pain. A colonoscopy is also recommended if you have a personal history of polyps or colorectal cancer, or if a close relative (parent, sibling, or child) had colorectal cancer before age 50 or multiple family members with colorectal cancer at any age.

Your doctor may also recommend continuing screening if you have never had a colonoscopy and are in good health with a life expectancy of more than 10 years. This is a conversation between you and your doctor — there is no hard cutoff at 75, only a change in what Medicare routinely covers. If your doctor thinks the benefit outweighs the risk for you, they can order it and document the reason.

How to know if Medicare will cover your colonoscopy

Ask your doctor to document the medical reason for the colonoscopy before scheduling. Common reasons Medicare accepts are: symptoms (bleeding, pain, or changes in bowel habits), prior polyps or colorectal cancer, family history of colorectal cancer, inflammatory bowel disease, or never having had screening and being in good overall health. Your doctor's office should submit the claim with this documentation.

If you are unsure whether Medicare will cover it, ask your doctor's office to contact Medicare before the procedure. You can also call Medicare at 1-800-MEDICARE (1-800-633-4227) and describe your situation. If there is any doubt, ask your doctor's office to provide an Advance Beneficiary Notice before the appointment so you know in advance what you might owe.

Alternatives if colonoscopy is not covered

If Medicare denies coverage for a screening colonoscopy after 75, you have options. You can pay out of pocket — costs vary widely by location and facility, typically ranging from $1,000 to $3,000 for a screening procedure without polyp removal. Some community health centers and hospital financial information programs offer reduced-cost colonoscopies based on income.

You can also ask your doctor about other colorectal cancer screening methods. Fecal immunochemical testing (FIT) — a stool test — is covered by Medicare for screening at any age and can be done at home. High-sensitivity guaiac fecal occult blood test (gFOBT) is also an option. These are less sensitive than colonoscopy but may be reasonable alternatives if colonoscopy is not covered and you want some form of screening.

What happens if you had a normal colonoscopy before 75

If you had a normal colonoscopy before age 75 with no polyps found, you generally do not need another one after 75 unless symptoms develop. The standard recommendation is that a normal colonoscopy protects you for 10 years. If your last normal colonoscopy was within the past 10 years and you have no new symptoms or risk factors, there is no medical reason for another one, and Medicare would not cover it.

If you had polyps removed before age 75, the timing for follow-up depends on what was found. Your doctor will tell you when to return. If that follow-up is due after you turn 75, Medicare will cover it because it is based on your prior findings, not routine screening.

Frequently Asked Questions

Can I get a colonoscopy after 75 if I have never had one?

Yes, if your doctor thinks it is medically necessary and you are in good enough health that screening would benefit you. Medicare covers it if your doctor documents a medical reason — such as symptoms, family history, or never having been screened and being in good health with a life expectancy over 10 years. The key is that your doctor must order it for a documented reason, not just routine screening.

What if my doctor says I need a colonoscopy but Medicare denies it?

Contact your doctor's office and ask them to appeal the denial or resubmit the claim with more detailed documentation of the medical reason. You can also file an appeal yourself through Medicare. If you signed an Advance Beneficiary Notice, you are responsible for the bill. If you did not sign one and Medicare denies it, ask the provider to write off the charge or work out a payment plan.

Does Medicare cover the anesthesia used during colonoscopy?

Yes, if the colonoscopy itself is covered, the anesthesia (usually sedation) is included. You do not pay separately for it. It is part of the procedure cost.

If a polyp is found during a screening colonoscopy after 75, does Medicare cover the removal?

Medicare may cover the removal and reclassify the procedure as diagnostic, but this is not may provide. To be safe, have your doctor document a medical reason before the procedure rather than relying on what might be found during it.

How often can I have a colonoscopy after 75 if Medicare covers it?

If it is diagnostic (based on symptoms or prior findings), the frequency depends on what is found and your doctor's recommendation. If it is screening, Medicare typically covers it every 10 years, but only if your doctor documents that screening is medically necessary for you.
