How much does a colonoscopy cost?NPI VERIFIED
It depends on the type. Without insurance, hospitals that publish a self-pay price list a median of $1,475 for a diagnostic colonoscopy to $1,750 for one with polyp removal. With insurance, the median rate hospitals negotiated runs from $1,020 for a diagnostic colonoscopy to $1,290 for one with polyp removal, across 1,005–1,023 US hospitals that publish federally required price files. Hospitals disagree more than the colonoscopy types do: for a diagnostic colonoscopy, the priciest tenth negotiated more than $2,828, 8.6× the cheapest tenth (under $329).

These are contract reference rates, not your bill. A median across hospitals is not a quote for your plan or network. Your out-of-pocket cost depends on your deductible, coinsurance and network status.
A preventive screening colonoscopy is usually covered without cost-sharing. The prices here are the diagnostic code and the polyp-removal code — what a screening can turn into once something is found or treated.
This is the hospital's facility fee. The physician performing the procedure, anesthesia and any pathology are billed separately.
Coverage: 1,005–1,023 of the 5,419 hospitals in the CMS roster have an identity-verified price file with these services in our data. It is not a random sample, and a hospital missing here has not been judged non-compliant — we may simply not have its file yet. Up to 69 of these hospital files were more than 12 months old at extraction; we keep the figures and say so.

Frequently asked questions
- How much does a colonoscopy cost without insurance?
- Hospitals that publish a self-pay (cash) price list a median of $1,475 for a diagnostic colonoscopy up to $1,750 for one with polyp removal (605–636 hospitals list one, depending on the type). That is the hospital's facility charge — the doctor performing it, anesthesia and any pathology bill separately. Ambulatory surgery and endoscopy centers aren't in these hospital files and are often cheaper for self-pay patients.
- How much does a colonoscopy cost with insurance?
- With insurance, the hospital's negotiated rate is what your plan is billed. Median negotiated rates run from $1,020 for a diagnostic colonoscopy to $1,290 for one with polyp removal. Until you meet your deductible you typically pay that negotiated amount; after it, your coinsurance or copay applies. Your plan's own rate can sit above or below these figures.
- Which colonoscopy costs the most?
- Of the 2 colonoscopy types here, one with polyp removal has the highest median negotiated rate ($1,290) and one with polyp removal the highest median cash price ($1,750); a diagnostic colonoscopy has the lowest negotiated rate ($1,020). Each one has its own page with state and insurance-type breakdowns.
- Why does the same colonoscopy cost so differently from hospital to hospital?
- Each hospital negotiates separately with each insurer. For a diagnostic colonoscopy, the priciest tenth of hospitals negotiated more than $2,828 — 8.6 times the cheapest tenth (under $329).
- Is the cash price cheaper than using insurance?
- Usually not, but sometimes. Median cash prices here are 1.4× the median negotiated rates. Still, at 29%–30% of the hospitals that list a cash price (depending on the type), it is lower than that hospital's own median negotiated rate. If you have a high deductible, ask the hospital for its self-pay price before you book.
- What is the Medicare rate shown here?
- It is the CMS national outpatient (OPPS) payment rate (July 2026): $950–$1,223 depending on the type. We show it as a government baseline: median negotiated rates are 1.1 times it.
