Illinois presents two distinct markets: Chicago (highly competitive, high commercial rates, major academic medical centers) and downstate (lower density, smaller regional systems, lower rates). Northwestern Medicine, Advocate Aurora Health, and Rush University Medical Center compete aggressively in the Chicago market. Downstate Illinois prices typically run 20–35% below Chicago-area rates for identical services. Mammogram pricing splits along two axes: screening vs. diagnostic classification and facility type. Screening mammograms are covered at 100% under the ACA's preventive care mandate for most commercial plans, but a finding during screening that triggers additional views or a diagnostic repeat converts a $0 visit to a cost-sharing event. Hospital-based breast imaging centers add facility fees that freestanding imaging centers don't charge - typically 2–3× higher for the identical study.

Why prices vary - and what it means for your coverage

A small number of hospitals (5) report prices above $400, including Taylorville Memorial Hospital at $739, 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 $96 versus $118 inpatient (about 1.2× more), so where a procedure happens often matters more than which hospital you pick. Whether the scan happens in a hospital outpatient department (which adds a separate facility fee) or a freestanding imaging center is usually the single biggest driver of price for this procedure.

On top of the facility price, your actual bill depends on your deductible, your out-of-pocket maximum, and whether every provider involved - not just the facility - is in-network.

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 mammogram so much cheaper at some Illinois hospitals?

Prices vary up to 96.7× because each hospital sets its own list price, cash discount, and insurer-negotiated rates. In Illinois, the median cash (self-pay) price is $108 versus a median negotiated rate of $34 - about 3.2× 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 mammogram in Illinois?

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.
