Mammogram Cost Without Insurance in California (2026)

Understand the cash prices for routine breast cancer screenings vs. diagnostic exams in California.

For uninsured residents of California, the cost of a mammogram can legally vary significantly between providers. While the average cash price is approx. $450, prices in major metro areas like Los Angeles and San Francisco can be higher due to facility fees, while independent imaging centers in rural parts of California might offer lower rates.

Under the No Surprises Act, if you are uninsured, you have the right to a "Good Faith Estimate" from any provider in California before you schedule your screening. This ensures you aren't hit with a bill substantially higher than quoted.

Frequently Asked Questions

How much does a mammogram cost out-of-pocket in California?

In California, a screening mammogram typically costs between $200 - $900 without insurance. The average cash price is around $450. Diagnostic mammograms (used if a lump is found) are often more expensive, ranging from $400 to over $1,000.

Is a screening mammogram free?

Under the Affordable Care Act (ACA), screening mammograms are covered 100% by insurance (including plans from Kaiser Permanente) for women over 40. However, if you do not have insurance, you must pay the full price unless you qualify for Medi-Cal or other assistance programs.

What is the difference between Screening and Diagnostic mammograms?

A **screening mammogram** is a routine check-up for women with no symptoms. A **diagnostic mammogram** is performed if a lump is felt or if a screening mammogram shows an abnormality. Diagnostic mammograms take more images and are interpreted immediately by a radiologist, making them more expensive.

Does a 3D mammogram cost more?

Yes, 3D mammograms (tomosynthesis) often cost $50-$100 more than traditional 2D mammograms. While many insurance plans now cover 3D screenings, cash-pay patients should ask for the specific price difference upfront.

Where can I get a free or low-cost mammogram in California?

The CDC's National Breast and Cervical Cancer Early Detection Program (NBCCEDP) provides free or low-cost mammograms to low-income, uninsured, and underinsured women. In California, you can also check into Medi-Cal or local health departments in cities like Los Angeles for sliding-scale fees.
