California has the most competitive commercial hospital market in the country, with aggressive multi-system competition in every major metro driving meaningful price variation. Kaiser Permanente's integrated payer-provider model covers roughly 40% of the insured population in the state - if you're Kaiser-enrolled, the prices here largely don't apply. California's robust price transparency enforcement under SB 1204 means the data here is more complete than in most states. 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 (7) report prices above $472, including Sutter Medical Center, Sacramento at $929, 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 $101 versus $210 inpatient (about 2.1× 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.

None of the prices above are what you'll necessarily owe: your deductible, out-of-pocket maximum, and each provider's network status all still apply.

Frequently asked questions: mammogram costs in California

How much does a mammogram cost in California?

Across 164 California hospitals that publish prices, a mammogram ranges from $31 to $2,968, with a median of $103. Most facilities fall between $85 and $187. What you pay depends on the facility, your insurance, and whether you have met your deductible.

Where is the cheapest place to get a mammogram in California?

Based on declared prices, the lowest-cost facility in our California data is ADVENTIST HEALTH - REEDLEY at about $51. By metro, Long Beach has the lowest median ($63). 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 California hospitals?

Prices vary up to 95.7× because each hospital sets its own list price, cash discount, and insurer-negotiated rates. In California, the median cash (self-pay) price is $103 versus a median negotiated rate of $40 - about 2.6× 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 California?

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.
