How Much Does a Colonoscopy Cost Without Insurance in 2026?

June 1, 2026 · Cost Guide · 5 min read

A colonoscopy costs $800 to $3,500 without insurance in 2026, with the national average for self-pay patients landing around $1,400 at an ambulatory surgery center. The same procedure at a hospital outpatient department typically costs twice as much. Facility type — not geography — is the dominant cost variable, and patients who shop between facility types can save $1,000 or more on the identical procedure with the same physician.

Colonoscopy Costs by Facility Type (2026)

Based on Medicare reimbursement data and self-pay rate surveys across major metro areas, here is what colonoscopies actually cost by facility type:

Hospital-based outpatient facilities carry significant overhead — facility fees subsidize emergency capacity, 24/7 staffing, and hospital infrastructure — none of which you need for a routine colonoscopy. Freestanding ASCs exist specifically for lower-acuity procedures and typically charge facility fees 40 to 60% lower.

What Drives the Price Up

Polyp removal (polypectomy)

If the gastroenterologist finds and removes a polyp during your procedure, the colonoscopy becomes a therapeutic rather than purely diagnostic procedure. Polypectomy adds $200 to $800 in facility and physician fees. Roughly 40% of colonoscopies in patients over 50 involve polyp removal, so factor this into your budget planning.

Biopsy pathology

Any tissue removed is sent to a pathology lab for analysis. Pathology bills are a separate charge from the colonoscopy itself — typically $100 to $400 depending on the number of specimens. This charge often arrives weeks after the procedure from a different provider than your gastroenterologist.

Sedation type

Standard colonoscopies use either moderate sedation (administered by the GI nurse or gastroenterologist, billed at roughly $100 to $200) or monitored anesthesia care administered by an anesthesiologist ($200 to $500). Some patients request propofol, which requires an anesthesiologist at higher cost. If cost is a concern, ask which sedation type is included in the quoted price.

Repeat procedure

An incomplete colonoscopy — where the physician cannot reach the cecum due to inadequate bowel prep or anatomical factors — requires a repeat procedure. You pay twice. Following the bowel preparation instructions precisely is not just medically important; it is financially significant.

Colonoscopy Costs in Major Cities

Self-pay colonoscopy prices vary by metro area, reflecting regional labor and facility costs. Based on ASC pricing in 2026:

• Dallas, TX: $900–$1,500 at ASC; $1,800–$2,800 at hospital
• Chicago, IL: $1,100–$1,800 at ASC; $2,200–$3,400 at hospital
• Los Angeles, CA: $1,200–$2,000 at ASC; $2,500–$3,800 at hospital
• Houston, TX: $850–$1,400 at ASC; $1,700–$2,600 at hospital
• New York City: $1,400–$2,400 at ASC; $2,800–$4,500 at hospital
• Phoenix, AZ: $800–$1,300 at ASC; $1,600–$2,400 at hospital

Insurance Coverage: What to Know Before You Book

The ACA mandates zero-cost preventive colonoscopy coverage for most insured patients 45 and older — with a major exception: the polyp removal upgrade trap. When a gastroenterologist removes a polyp during what was scheduled as a preventive screening, some insurers reclassify the encounter as a diagnostic or surgical visit, which triggers your deductible and coinsurance. A procedure you expected to cost $0 can generate a $500 to $2,000 bill. Legislation has restricted this practice for some plan types, but it remains a risk under grandfathered health plans and some state-regulated policies.

Before scheduling, call your insurer and ask specifically: "If a polyp is removed during my preventive colonoscopy, will you apply my deductible or coinsurance?" Get the answer in writing.

How to Reduce Your Colonoscopy Cost

1. Choose an ASC over a hospital. Ask your gastroenterologist's office at which facilities they perform colonoscopies and request the ASC option. Most GI physicians operate at both hospital and ASC settings.
2. Request the self-pay rate. Call the facility's billing department and ask for their cash-pay price for a screening colonoscopy (CPT code 45378). This rate is typically 15 to 40% below the standard billed rate and is often not volunteered automatically.
3. Use Healthcare Bluebook or FAIR Health. Both publish cost transparency data by zip code. Use these to benchmark whether the quote you received is reasonable for your market.
4. Check community health centers. Federally Qualified Health Centers (FQHCs) provide colonoscopies on a sliding-fee scale. For patients at 100 to 200% of the federal poverty level, costs can be $0 to $300.
5. Use your HSA or FSA. Colonoscopies are qualified medical expenses. If you have funds in a health savings account, using pre-tax dollars effectively gives you a 22 to 37% discount depending on your tax bracket. See our guide on FSA vs. HSA accounts for how to maximize these accounts.
6. Request an itemized bill and audit it. Medical billing errors are common. After your procedure, request an itemized bill and compare each charge against what was performed. Our guide on how to dispute a medical bill walks through the dispute process.

Colonoscopy vs. Other Colorectal Screening Options

Colonoscopy is not the only colorectal cancer screening option, though it remains the gold standard because it both detects and removes polyps in one procedure. Lower-cost alternatives include:

• Cologuard (stool DNA test): $600 to $700 without insurance; done at home and mailed to a lab. Requires a colonoscopy follow-up if positive. Recommended every 3 years.
• FIT test (fecal immunochemical test): $20 to $30 at most labs; done annually at home. Positive results require colonoscopy follow-up.
• CT colonography (virtual colonoscopy): $400 to $900 without insurance; no sedation required. Cannot remove polyps — positive results require standard colonoscopy.

For patients who are primarily cost-constrained, annual FIT testing or Cologuard every 3 years with colonoscopy reserved for positive results is a medically accepted screening strategy.
