How much does a diagnostic colonoscopy cost in the US?

Across 1,023 hospitals that publish federally required price files, the median negotiated rate is $1,020, and the middle half of hospitals fall between $827 and $1,842. Self-pay cash prices have a median of $1,475 across the 636 hospitals that list one. What you pay out of pocket depends on your deductible, coinsurance and network.

Why do Diagnostic Colonoscopy prices vary so much?

Each hospital negotiates separately with each insurer. In these files the priciest tenth of hospitals negotiated more than 8.6 times what the cheapest tenth did, and state medians run from $115 in Puerto Rico to $2,829 in New Jersey.

Is the cash price cheaper than using insurance?

Sometimes. At 192 of the 636 hospitals that list a cash price (30%), 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?

$950 is the CMS national outpatient (OPPS) payment rate for this service (July 2026). We show it as a government baseline: the national median negotiated rate is 1.1 times it.

Each bar counts hospitals whose median rate falls in that price band; the last, dashed bar holds the 26 at $5,000 or more. The cheapest tenth negotiated under $329, the priciest tenth over $2,828 — 8.6× apart for the same procedure.

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; this page shows the diagnostic code, which is 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: 1,023 of the 5,419 hospitals in the CMS roster have an identity-verified price file with this procedure 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. 69 of these 1,023 hospital files were more than 12 months old at extraction — hospitals must update yearly; we keep the figures and say so rather than hide them.
