Quick take

  • UM Charles Regional Medical Center is the lowest-cost option at $216 - $872 below the state median, just by choosing where you go.
  • Ask for the cash price if your deductible isn't met - the median cash price here is $1,088, and it's often lower than what insurance pays before your deductible is satisfied.
  • Ask whether this procedure can be done at a freestanding ambulatory surgical center - they're typically 30-60% cheaper than a hospital for identical care, and most aren't in this hospital-only dataset.

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–$10,979
  • Facility fee $201–$2,703
  • Professional fee $84–$8,276

Estimated from CMS fee schedules + commercial rate multipliers

Hospital Inpatient
$285–$10,979
  • Facility fee $201–$2,703
  • 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.

Maryland operates the nation's only all-payer hospital rate-setting system through the Health Services Cost Review Commission (HSCRC) - all payers, including Medicare, Medicaid, commercial, and self-pay, pay the same regulated rates at each facility. This makes Maryland's cash prices more meaningful than in other states, because the discounting common elsewhere is largely prohibited. Johns Hopkins Medicine and University of Maryland Medical System anchor the academic tier. 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

Setting matters too: the median outpatient price is $1,437 versus $1,437 inpatient, 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 ~$1,936
Deductible met - 20% coinsurance ~$387
Out-of-network provider $4,259+

Frequently asked questions: colonoscopy costs in Maryland

How much does a colonoscopy cost in Maryland?

Across 15 Maryland hospitals that publish prices, a colonoscopy ranges from $103 to $80,569, with a median of $1,088. Most facilities fall between $233 and $1,796. 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 Maryland?

Based on declared prices, the lowest-cost facility in our Maryland data is Northwest Hospital Center at about $201. By metro, Towson has the lowest median ($233). Freestanding ambulatory surgery and imaging 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 Maryland hospitals?

Prices vary up to 782.2× because each hospital sets its own list price, cash discount, and insurer-negotiated rates. In Maryland, the median cash (self-pay) price is $1,088 versus a median negotiated rate of $135 - about 8.1× higher. Asking for the cash price or 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 Maryland?

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 ASCs or independent 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.
