Medicare covers colorectal cancer screening for Georgia beneficiaries at no cost, and coverage now begins at age 45. This guide explains every test Medicare pays for, what you owe if a polyp is found and removed, and how to get screened whether you live in metro Atlanta or a rural county hours from the nearest gastroenterologist.
If you have Original Medicare in Georgia, you pay $0 for a colorectal cancer screening, no matter which test you choose, as long as your provider accepts Medicare assignment.Centers for Medicare & Medicaid Services. (n.d.). Preventive and screening services. medicare.gov. Retrieved Aug 8, 2026, from https://www.medicare.gov/coverage/preventive-screening-services That covers at-home stool tests you can complete without leaving the house, as well as colonoscopy, the test that both screens for and can remove precancerous polyps in one visit. Coverage flows from a benefit Congress added to Medicare in 1997 and has expanded many times since, most recently to lower the starting age to 45 and to shield you from a surprise bill when a screening colonoscopy turns into a polyp removal.

What Georgia Medicare Colorectal Cancer Screening Covers
Medicare's colorectal cancer screening benefit is defined in Section 1861(pp) of the Social Security Act (42 U.S.C. 1395x(pp)) and implemented in regulation at 42 CFR 410.37. It covers several different tests, so nearly every beneficiary has a workable option regardless of mobility, distance, or personal preference. You do not have to pick the most invasive test to be covered.
At-home stool tests. These detect signs of cancer in a stool sample you collect at home and mail to a lab. Medicare covers three:
- Fecal Immunochemical Test (FIT), once every year (HCPCS code G0328). It looks for hidden blood and needs no special diet.
- Cologuard (multi-target stool DNA test), once every 3 years for average-risk beneficiaries (HCPCS code 81528). It checks for both blood and DNA markers.
- Fecal Occult Blood Test (FOBT), once every year (HCPCS code 82270). This is the older blood-based test, now largely replaced by FIT.
In-person tests. These use a scope or imaging to look inside the colon:
- Screening colonoscopy examines the entire colon and lets the doctor remove polyps during the same visit. Medicare covers it once every 10 years for average-risk beneficiaries (HCPCS code G0121) and once every 2 years for high-risk beneficiaries (HCPCS code G0105). It requires bowel preparation the day before and sedation.
- Flexible sigmoidoscopy examines the lower colon only. Medicare covers it once every 4 years (HCPCS code G0104).
- Barium enema is an X-ray study Medicare covers only as an alternative when you cannot have a scope (HCPCS codes G0106 and G0120). It is rarely used today.
| Test | Average-Risk Frequency | High-Risk Frequency | HCPCS Code |
|---|---|---|---|
| FIT | Once a year | Once a year | G0328 |
| Cologuard (stool DNA) | Once every 3 years | Once every 3 years | 81528 |
| FOBT | Once a year | Once a year | 82270 |
| Flexible sigmoidoscopy | Once every 4 years | Once every 4 years | G0104 |
| Colonoscopy | Once every 10 years | Once every 2 years | G0121 (avg), G0105 (high) |
| Barium enema | Only as an alternative to a scope | Only as an alternative to a scope | G0106, G0120 |
Medicare coordinates these intervals so you are not double-tested. Under 42 CFR 410.37, a screening colonoscopy is covered once every 120 months if you are not at high risk and once every 24 months if you are, a screening flexible sigmoidoscopy once every 48 months, and a screening fecal-occult blood test once every 12 months. If you are not at high risk and have already had a screening colonoscopy, Medicare will not pay for a screening sigmoidoscopy until 119 months have passed. Your doctor tracks your last screening date and type to schedule the next one correctly.U.S. Government Publishing Office.

Who Qualifies, and When Screening Starts
Medicare sets a minimum age of 45 for the stool-based tests and for flexible sigmoidoscopy, while a screening colonoscopy carries no minimum-age limitation in the regulation.U.S. Government Publishing Office. (n.d.). 42 CFR 410.37 — Colorectal cancer screening tests: conditions for and limitations on coverage. ecfr.gov. Retrieved Jul 11, 2026, from https://www.ecfr.gov/current/title-42/section-410.37 That reflects the U.S. Preventive Services Task Force's 2021 recommendation, which lowered the start age from 50 to 45 in response to rising colorectal cancer in younger adults; CMS aligned Medicare coverage with it effective January 1, 2023. Because most people enroll in Medicare at 65, the age-45 change matters most for Georgians who qualify for Medicare earlier through a disability or end-stage renal disease.
If you have a higher-than-average risk, Medicare covers screening colonoscopy more often, once every 24 months instead of once every 120 months, which is every 2 years rather than every 10.U.S. Government Publishing Office. (n.d.). 42 CFR 410.37 — Colorectal cancer screening tests: conditions for and limitations on coverage. ecfr.gov. Retrieved Jul 11, 2026, from https://www.ecfr.gov/current/title-42/section-410.37 You are considered high-risk if you have any of the following:
- A personal history of adenomatous polyps or colorectal cancer.
- Inflammatory bowel disease, meaning Crohn's disease or ulcerative colitis.
- A close relative (parent, sibling, or child) who had colorectal cancer or precancerous polyps, especially before age 60.
- A hereditary syndrome such as Lynch syndrome or familial adenomatous polyposis.
If any of these apply to you, tell your doctor so your screening is coded and scheduled as high-risk. People with a strong family history or a hereditary syndrome should also ask about a referral for genetic counseling.
What Georgia Medicare Colorectal Cancer Screening Costs
The screening itself is free. The Affordable Care Act (Section 4104, Public Law 111-148) waived the Part B deductible and coinsurance for preventive services the Task Force grades A or B, and colorectal cancer screening qualifies. So under Original Medicare you pay $0 for a FIT, Cologuard, FOBT, sigmoidoscopy, or screening colonoscopy when the provider accepts assignment.Centers for Medicare & Medicaid Services. (n.d.). Preventive and screening services. medicare.gov. Retrieved Aug 8, 2026, from https://www.medicare.gov/coverage/preventive-screening-services
The one exception is the "polyp problem." If your doctor finds and removes a polyp during a screening colonoscopy, Medicare reclassifies the visit as diagnostic, and historically that triggered a 20% coinsurance bill the day you thought you were getting a free screening.Centers for Medicare & Medicaid Services. (n.d.). Preventive and screening services. medicare.gov. Retrieved Aug 8, 2026, from https://www.medicare.gov/coverage/preventive-screening-services Congress fixed this in the Consolidated Appropriations Act, 2021 (Section 122, Public Law 116-260), which phases that coinsurance down to nothing:
- 2022 through 2026: you pay 15% of the Medicare-approved amount.
- 2027 through 2029: you pay 10%.
- 2030 and after: you pay $0.Centers for Medicare & Medicaid Services. (n.d.). Preventive and screening services. medicare.gov. Retrieved Aug 8, 2026, from https://www.medicare.gov/coverage/preventive-screening-services
So a screening colonoscopy in 2026 that turns up a polyp leaves you owing 15% coinsurance rather than the old 20%. The Part B deductible ($283 in 2026) can also apply to that portion if you have not already met it for the year. The screening portion itself stays $0.Centers for Medicare & Medicaid Services.

| Scenario | Your Cost in 2026 |
|---|---|
| Screening colonoscopy, no polyp found | $0 |
| Screening colonoscopy, polyp found and removed | 15% coinsurance on the procedure |
| At-home FIT, Cologuard, or FOBT screening | $0 |
| Screening sigmoidoscopy, nothing removed | $0 |
| Diagnostic colonoscopy (ordered because of symptoms) | Part B deductible plus 20% coinsurance |
Colorectal screening is also not the only preventive service Medicare covers at no charge, and several of them can be arranged at the same primary care visit where you set up your screening. Part B covers a yearly alcohol misuse screening, plus up to four brief counseling sessions a year if that screening comes back positive, with nothing owed when the provider accepts assignment.Centers for Medicare & Medicaid Services. (n.d.). Medicare.gov — Alcohol misuse screenings & counseling. medicare.gov. Retrieved Jul 10, 2026, from https://www.medicare.gov/coverage/alcohol-misuse-screenings-counseling
Two costs can surprise people even when the screening is free: anesthesia billed separately by an anesthesiologist may carry its own cost-sharing, and a Medicare Advantage plan may require you to use an in-network gastroenterologist. Ask about both before your procedure.
How Coverage Plays Out: Real Scenarios
These hypothetical examples show how the rules above translate into real bills for Georgia beneficiaries.
A rural beneficiary who wants to avoid the drive. A 68-year-old in Worth County lives 30 miles from the nearest gastroenterologist at Phoebe Putney in Albany and would rather not travel or do the bowel prep. Her primary care doctor orders an annual FIT (G0328). A kit arrives in the mail, she completes it at home, and returns it. The result is negative, she pays $0, and she repeats the test each year.Centers for Medicare & Medicaid Services. (n.d.). Preventive and screening services. medicare.gov. Retrieved Aug 8, 2026, from https://www.medicare.gov/coverage/preventive-screening-services
An average-risk first screening. A 65-year-old in DeKalb County has never been screened. Her doctor orders a screening colonoscopy (G0121) at Emory Endoscopy Center. No polyps are found, so she pays $0 and does not need another colonoscopy for 10 years.Centers for Medicare & Medicaid Services. (n.d.). Preventive and screening services. medicare.gov. Retrieved Aug 8, 2026, from https://www.medicare.gov/coverage/preventive-screening-services
A polyp is found and removed. A 70-year-old in Cobb County has an average-risk screening colonoscopy (G0121) at Wellstar. The doctor finds and removes a small adenoma. Because the visit converts to diagnostic, she owes 15% coinsurance under the 2026 rule instead of the old 20%, and the Part B deductible may apply if she has not met it yet. Had this happened in 2030, she would owe nothing.Centers for Medicare & Medicaid Services. (n.d.). Preventive and screening services. medicare.gov. Retrieved Aug 8, 2026, from https://www.medicare.gov/coverage/preventive-screening-services
A mobility-limited beneficiary. A 72-year-old in Macon finds bowel prep and a procedure difficult. With her doctor at Atrium Health Navicent, she chooses Cologuard (81528), completes the stool test at home with help, and pays $0. She repeats it every 3 years.Centers for Medicare & Medicaid Services. (n.d.). Preventive and screening services. medicare.gov.

Finding Screening Care in Georgia
Metro Atlanta has deep gastroenterology capacity, including Emory Digestive Health, Piedmont GI, Wellstar Gastroenterology, Northside Hospital, and Atlanta Gastroenterology Associates. Around the state, endoscopy is anchored by regional systems: Augusta University Health in the east, Atrium Health Navicent in Macon, Memorial Health and St. Joseph's/Candler in Savannah, Phoebe Putney in Albany for the southwest, and Piedmont Athens Regional and St. Mary's in the northeast.
Many rural Georgia counties have no local gastroenterologist, which means a colonoscopy can require a long drive to a regional center. That is exactly why at-home stool testing is so important here. A FIT or Cologuard kit ordered by your primary care doctor is mailed to your home, completed there, and returned by mail, with no travel, no bowel prep, and no cost. Treat it as a real screening, not a second-best option; the best screening test is the one you will actually complete.
What to Ask and How to Avoid a Surprise Bill
A few questions before your appointment protect you from unexpected charges and keep your screening on track:
- Confirm the visit is coded as screening. Ask your doctor's office to bill your colonoscopy as a screening (G0121 or G0105), not diagnostic, if you have no symptoms. Wrong coding can turn a free test into a bill.
- Ask whether anesthesia is billed separately. If an anesthesiologist bills on their own, you may owe cost-sharing on that piece even when the screening is free.
- Under Medicare Advantage, check the network. Confirm your gastroenterologist and facility are in-network before scheduling.
- Mention your family history. It can qualify you as high-risk, which changes both how often you are covered and how the visit is coded.
- Know the polyp rule going in. If a polyp is removed in 2026 you owe 15%, not the full amount, and nothing from 2030 on. That knowledge keeps a real bill from feeling like a mistake.Centers for Medicare & Medicaid Services. (n.d.). Preventive and screening services. medicare.gov. Retrieved Aug 8, 2026, from https://www.medicare.gov/coverage/preventive-screening-services
- Ask about at-home options if a colonoscopy is a barrier. FIT and Cologuard are fully covered and can be done at home.
Frequently Asked Questions
At what age does Medicare start covering colorectal cancer screening?
Age 45 for the stool-based tests and for flexible sigmoidoscopy. A screening colonoscopy carries no minimum-age limitation at all.U.S. Government Publishing Office. (n.d.). 42 CFR 410.37 — Colorectal cancer screening tests: conditions for and limitations on coverage. ecfr.gov. Retrieved Jul 11, 2026, from https://www.ecfr.gov/current/title-42/section-410.37 Medicare aligned with the updated national guideline effective January 1, 2023, lowering the start age from 50.
Does Medicare cover a colonoscopy, and what will it cost?
Yes. A screening colonoscopy is covered at $0 under Original Medicare when the provider accepts assignment, once every 120 months if you are not at high risk and once every 24 months if you are, which is every 10 years and every 2 years respectively.U.S. Government Publishing Office. (n.d.). 42 CFR 410.37 — Colorectal cancer screening tests: conditions for and limitations on coverage. ecfr.gov. Retrieved Jul 11, 2026, from https://www.ecfr.gov/current/title-42/section-410.37
What happens if a polyp is removed during my screening colonoscopy?
The visit becomes diagnostic, so some coinsurance applies. Congress is phasing it out: you pay 15% in 2026, 10% from 2027 through 2029, and $0 starting in 2030. The screening portion stays free.
Does Medicare cover Cologuard and at-home stool tests?
Yes. Medicare covers Cologuard once every 3 years for average-risk beneficiaries, and FIT and FOBT once a year, all at $0. These are completed at home and mailed to a lab.
What makes me high-risk?
A personal history of polyps or colorectal cancer, inflammatory bowel disease, a close relative with colorectal cancer or polyps, or a hereditary syndrome such as Lynch syndrome or familial adenomatous polyposis.
What if my at-home stool test comes back positive?
A positive FIT or Cologuard means you need a follow-up colonoscopy to look for the cause. That follow-up is considered diagnostic and is subject to standard Part B cost-sharing rather than the $0 screening rate.
Does Medicare Advantage cover colorectal screening the same way?
Medicare Advantage plans must cover at least the same screenings at the same frequency and cost protections as Original Medicare, but they may limit you to in-network gastroenterologists and facilities.
How do I find a gastroenterologist in Georgia?
Ask your primary care doctor for a referral, search the provider directory at Medicare.gov, or contact a major program directly such as Emory Digestive Health, Augusta University Health, or Phoebe Putney. GeorgiaCares SHIP can also help you understand your coverage.
