Colonoscopy and insurance
Screening is covered on paper. Here’s when you still pay, and what it costs without insurance
US plans must cover screening colonoscopy for adults aged 45 to 75 in network, but a test billed as diagnostic can bring back the deductible, and Medicare charges 15% coinsurance when a polyp is removed. Self-paid, one Chinese hospital lists a sedated colonoscopy at about CNY 613 (≈ USD 91) before drugs and pathology.

Screening or diagnostic
The same colonoscopy can be free or come with a bill
Under the ACA, in-network screening for adults aged 45 to 75 is covered without cost-sharing, and plans may not charge for removing a polyp during a screening colonoscopy. A colonoscopy for symptoms is not a preventive service, and the American Cancer Society warns that insurers may treat some tests as diagnostic, so you may pay the usual deductible and copay. Ask your insurer how the test will be coded before it is booked.
Medicare and high deductibles
Where the costs come back
Medicare pays for screening colonoscopy, but if a polyp is removed you pay 15% coinsurance of the approved amount for the doctor, and in a hospital outpatient department or surgery centre also 15% for the facility. On a high-deductible plan, the 2026 minimum deductible is USD 1,700 self-only and the out-of-pocket maximum USD 8,500, so a diagnostic colonoscopy can be mostly self-paid.
UK and Australia
New private cover may not cover a problem you already have
UK moratorium policies exclude conditions you had in the 5 years before cover starts until you have gone 2 continuous years without symptoms, treatment or advice for them. In Australia, an insurer may impose a 12-month waiting period for a pre-existing condition, meaning signs or symptoms in the 6 months before you joined, and 2 months for most other hospital care.
The China route
A self-pay comparison, at listed prices
Chinese insurance will not cover a visitor’s planned colonoscopy. Commercial health insurance for expats usually requires about 180 days’ residence (Shanghai government guide), and Beijing’s new short-term visitor product covers accidents, medical payments and rescue; whether it covers planned procedures is not stated, so it needs checking case by case. We send you a self-pay quote from a Chinese hospital next to your out-of-pocket estimate at home.

Common questions
How much does a colonoscopy cost with and without insurance?
With US insurance, an in-network screening colonoscopy for adults aged 45 to 75 should cost nothing, though $0 is not guaranteed in every case. A diagnostic colonoscopy can carry your usual deductible and copay. Without insurance, the US average is about USD 2,750, and a UK private colonoscopy costs GBP 2,000–4,000. One Chinese hospital lists the colonoscopy and sedation at about CNY 613 (≈ USD 91) before drugs and pathology.
Is a colonoscopy covered as preventive or diagnostic?
It depends on why you have it. Screening without symptoms is a preventive service, and US private plans may not charge for polyp removal during it or for a follow-up colonoscopy after a positive stool test. A colonoscopy for symptoms is diagnostic, and the usual deductible and copay may apply. Medicare charges 15% coinsurance if a polyp is removed. Ask your insurer how it will be coded before the test.
At what age does insurance cover a colonoscopy?
Under the ACA, plans must cover colorectal cancer screening for adults aged 45 to 75 without cost-sharing in network. Medicare covers a screening colonoscopy once every 120 months, or every 24 months if you are at high risk. Coverage outside these rules depends on your plan, so ask your insurer for its written criteria.
How much do a colonoscopy and gastroscopy cost in China?
Checkup centres in China sell combined sedated gastroscopy and colonoscopy packages; one listing shows CNY 1,460–1,702 (≈ USD 220–250) for both. An aggregator estimates CNY 1,000–3,000 (≈ USD 150–450) all in for a sedated procedure at a tertiary hospital, highest in Beijing and Shanghai. Foreign patients pay the full listed price, and international departments charge more.
