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 $952 versus $972 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.

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 Maryland hospitals?

Typical prices vary about 5.5× (25th to 70th percentile of negotiated rates) because each hospital sets its own list price, cash discount, and insurer-negotiated rates. In Maryland, the median cash (self-pay) price is $853 versus a median negotiated rate of $199 - about 4.3× higher. 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 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.
