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

What does a colonoscopy cost in Maryland?

For a commercially insured patient, a colonoscopy in Maryland typically runs $747–$3,152 once facility and physician fees are combined. The median reported facility price across 15 hospitals is $1,088. The figures draw on CMS fee schedules and hospital price transparency data published under federal law.

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.

The same colonoscopy that costs $103 at Sinai Hospital of Baltimore in Baltimore reaches $80,569 at UM R Adams Cowley Shock Trauma Center in Baltimore — a 782.2× gap across the 15 Maryland hospitals reporting prices. The median Maryland price is $1,088. Most facilities fall between $233 and $1,796. Insurers negotiate this down to a median of $135, while self-pay patients are quoted $1,088 — about 8.1× higher, so asking for the cash or insurer-negotiated rate is often the single biggest lever on your bill. Location within the state matters too: Towson has the lowest metro median ($233) while Baltimore runs highest ($1,518) — a 6.5× difference inside Maryland alone.

These facilities report the highest prices for this procedure. Academic medical centers and specialty hospitals often top this list — their gross charges rarely reflect what anyone actually pays, but understanding the spread helps you negotiate.

Why prices vary this much

Setting drives much of the gap in Maryland: the median outpatient price is $1,437 versus $1,437 inpatient, so where a procedure is performed often matters more than which hospital you choose. Of the Maryland facilities reporting prices, 5 fall in a low-cost tier (up to $233) while 4 sit in a high-cost tier ($2,110 and up) — a lower-priced option almost always exists within the same state.

Among the cities with the most reporting hospitals, Baltimore has a median reported price of $1,518 across 4 facilities, while facilities in Towson tend to report lower prices (median: $233). City-level variation within a state often reflects local market structure, not procedure complexity.

The spread comes from how each hospital sets its chargemaster (the undiscounted list price), what cash discounts it applies, and what rates it negotiates with each insurer. Facility classification matters too — a hospital-owned outpatient center adds a facility fee that a freestanding clinic does not. Understanding these mechanics is the first step to paying less.

How insurance changes what you actually pay

Hospital list prices are only part of the picture. What you pay out of pocket depends on your deductible, your plan's out-of-pocket maximum, whether the facility is in-network, and whether your plan classifies the visit as outpatient or inpatient. A lower gross charge doesn't guarantee a lower bill if the facility is out-of-network or adds facility fees your plan doesn't cover.

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?

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.
