Colonoscopy Cost in Montana (2026): Average Prices & What You'll Pay

What does a colonoscopy cost in Montana?

The cost of a colonoscopy in Montana depends on how you pay. With commercial insurance it typically runs $785–$2,138, facility and physician fees combined. Medicare pays one national rate to every provider, and you generally owe about 20% of it (around $245) after the Part B deductible. Without insurance, posted hospital cash prices run $205–$1,182. The sections below break this down by coverage and by insurer. This estimate is based on CMS fee schedules and hospital price transparency data published under federal law.

  2. Can you give me the price in writing, with the billing codes it covers?
  3. What happens to the price if something extra is needed during the procedure?

How where you go changes what you pay for colonoscopy

The same colonoscopy bundles different services depending on the setting - facility fee, surgeon fee, and anesthesia each arrive as separate bills. Estimated ranges below reflect the typical full bundled cost, including all expected charges.

Hospital Outpatient
$285–$12,299
  • Facility fee $201–$4,023
  • Professional fee $84–$8,276

Estimated from CMS fee schedules + commercial rate multipliers

Hospital Inpatient
$298–$9,932
  • Facility fee $214–$1,656
  • Professional fee $84–$8,276

Estimated from CMS fee schedules + commercial rate multipliers

Ambulatory Surgery Center
$490–$10,410
  • Facility fee $222–$1,642
  • Professional fee $84–$8,276
  • Anesthesia $184–$492

Estimated from CMS fee schedules + commercial rate multipliers

Note: Ambulatory surgery centers (ASCs) are often 30–60% cheaper than hospital outpatient departments for the same procedure. Most ASC prices are not in the hospital transparency dataset above. Ask your doctor whether this procedure can be done at a freestanding ASC.

CommonSpirit Health (formerly SCL Health) and RiverStone Health cover most of Montana's population. The state's vast geography means most residents have little or no practical alternative to their nearest facility, effectively eliminating competitive pricing pressure outside Billings and Missoula. Critical access hospitals are widespread and use cost-based reimbursement for Medicare. Colonoscopy pricing is particularly sensitive to screening vs. diagnostic coding. A screening colonoscopy is typically covered at 100% under preventive care benefits, but if a polyp is removed or a finding is documented during the same visit, the claim is often re-coded as diagnostic - triggering your deductible and coinsurance. Ambulatory surgery centers perform over 70% of colonoscopies nationally and charge substantially less than hospital outpatient settings.

Why prices vary - and what it means for your coverage

A small number of hospitals (1) report prices above $1,826, including Mineral Community Hospital at $1,656, which drives most of the overall spread - excluding them, most facilities cluster in a much tighter band. Setting matters too: the median outpatient price is $476 versus $702 inpatient (about 1.5× more), so where a procedure happens often matters more than which hospital you pick. The biggest swing for this procedure is screening versus diagnostic coding - a polyp removed during a routine screening can recode the whole visit as diagnostic and trigger cost-sharing you weren't expecting.

What you pay out of pocket on top of this depends on your deductible, your plan's out-of-pocket maximum, and whether every provider involved is in-network - not just the facility.

Your situation Estimated out-of-pocket
Deductible not yet met ~$1,324
Deductible met - 20% coinsurance ~$265
Out-of-network provider $2,913+

Frequently asked questions: colonoscopy costs in Montana

How much does a colonoscopy cost in Montana?

The typical insurer-negotiated rate is $208, with most facilities between $89 and $601 (based on 34 hospitals reporting negotiated rates). That is the hospital's negotiated rate alone; with physician fees, a commercially insured patient's full episode is typically $785–$2,138. Posted cash prices at the middle 80% of Montana hospitals run $205–$1,182; outlier facilities above and below that range are left out. What you pay depends on the facility, your insurance, and whether you have met your deductible.

Where is the cheapest place to get a colonoscopy in Montana?

Based on declared prices, the lowest posted price in our Montana data is Bitterroot Health - Daly Hospital in Hamilton at about $205. By metro, Choteau has the lowest median ($214). Freestanding ambulatory surgery centers are often cheaper still and may not appear in hospital price data - ask your doctor whether one is an option.

Why is a colonoscopy so much cheaper at some Montana hospitals?

Typical prices vary about 6.8× (25th to 70th percentile of negotiated rates) because each hospital sets its own list price, cash discount, and insurer-negotiated rates. In Montana, the median cash (self-pay) price is $476 versus a median negotiated rate of $1,177 - cash is the lower number at many hospitals. Asking for the cash price as well as your insurer's negotiated rate is often the single biggest lever on what you pay.

How much will I actually pay out of pocket for a colonoscopy in Montana?

Your out-of-pocket cost depends on your deductible, coinsurance, out-of-pocket maximum, and whether the facility is in-network - not just the sticker price. If you have not met your deductible, you will typically pay the negotiated rate in full until you do. Use the CostKits cost forecaster to estimate your specific out-of-pocket amount before you go.

What matters before you schedule

ASC vs. hospital

Hospital outpatient departments typically charge 2-4x more than ambulatory surgery centers for the same colonoscopy - same outcome, very different bill. Call ahead and ask for a self-pay or cash quote at each setting you're considering.

What's on your bill

A colonoscopy involves multiple providers who bill separately - typically Facility Fee, Gastroenterologist Fee, Anesthesia. Check each line item against your Explanation of Benefits to catch billing errors.

Cost by type

Which type your doctor orders for this colonoscopy changes the billing code, and what you pay. For example: Billed as preventive care - often covered at $0 under the ACA when you are average-risk and in-network.

What to ask before you book

Get the CPT code from your doctor, confirm every provider involved (not just the facility) is in-network, ask for the cash-pay rate if you're uninsured or haven't met your deductible, and request a written estimate for colonoscopy before you schedule.
