How Much Does a Colonoscopy Cost?

The most important cost factor for a colonoscopy is how it is classified. A screening colonoscopy — performed on a patient with no symptoms and no prior findings — must be covered at $0 out-of-pocket under the Affordable Care Act for patients with insurance ². This applies even if the provider is out-of-network.

A diagnostic colonoscopy — ordered because of symptoms like rectal bleeding, abnormal stool tests, or a history of polyps — is billed as a standard medical procedure. Without insurance, diagnostic colonoscopies average $2,750 to $4,500 ¹. With insurance, you owe your deductible and coinsurance, typically $500 to $1,500 out of pocket.

The billing trap: if a polyp is found and removed during a screening colonoscopy, some insurers have historically reclassified the procedure as diagnostic, shifting costs to the patient. Recent regulatory guidance has closed this loophole for most plans, but it still occurs. Always confirm with your insurer before the procedure how polyp removal during a screening will be billed.

Several components make up the total colonoscopy bill, and each is typically billed separately:

• —Facility fee — The largest component, covering the use of the endoscopy suite, nursing staff, and equipment. Ranges from $1,000 to $3,000 depending on the facility.
• —Physician fee — The gastroenterologist's professional fee for performing the procedure, typically $400 to $1,200.
• —Anesthesia — Most colonoscopies use propofol sedation administered by an anesthesiologist or CRNA. This adds $400 to $1,000 and is billed separately.
• —Pathology — If polyps are removed, they are sent for biopsy. Pathology fees add $150 to $500 per specimen.
• —Bowel prep kit — The preparation solution costs $20 to $80 and is usually a separate out-of-pocket expense.

The total can escalate quickly when polyps are found. A straightforward screening with no findings might cost the facility $2,000, while the same procedure with three polyps removed and sent for pathology could reach $4,500 or more.

Where you have your colonoscopy performed significantly affects the cost. Hospital outpatient departments charge the highest rates — typically $3,000 to $5,500 — because of the facility fee. Ambulatory surgery centers (ASCs) perform the same procedure for $1,500 to $2,800, saving 30-50%.

The quality of care at an ASC is equivalent to a hospital for routine colonoscopies. ASCs are purpose-built for outpatient procedures, and most gastroenterologists perform colonoscopies at both settings. Ask your gastroenterologist if they have privileges at a nearby ASC — this single choice can save you $1,000 or more. If you are uninsured, ASCs are also more likely to offer transparent cash-pay pricing.

Whether your colonoscopy is screening or diagnostic, there are steps to minimize your cost:

• —Confirm screening classification in advance — Get written confirmation from your insurer that your colonoscopy is classified as a preventive screening and will be covered at no cost.
• —Choose an ambulatory surgery center — Save 30-50% compared to hospital outpatient departments for the same procedure.
• —Verify all providers are in-network — The gastroenterologist, anesthesiologist, and facility should all be in-network. Out-of-network anesthesiologists are a common source of surprise bills.
• —Ask about polyp removal billing — Confirm before the procedure that polyp removal during a screening will not trigger reclassification to diagnostic.
• —Negotiate if uninsured — Cash-pay colonoscopy packages at ASCs often run $1,500-$2,000, well below hospital rates.
• —Compare your bill on ORVO — Upload your colonoscopy bill to see how your charges compare to other facilities in your area.
