$2.52M Onsite Mammography data breach class action settlement

Onsite Mammography agreed to pay $2.525 million to resolve claims it failed to prevent a 2024 data breach that compromised patient information.

The Onsite Mammography class action settlement benefits individuals who received a data breach notice from Onsite Mammography informing them that their information may have been compromised in October 2024.

According to the Onsite Mammography data breach class action lawsuit, Onsite Mammography failed to implement reasonable cybersecurity measures that could have prevented a 2024 data breach. As a result of Onsite Mammography’s alleged negligence, hackers gained access to sensitive patient information, the class action lawsuit contends.

Onsite Mammography, now known as Onsite Women’s Health, provides mammography and related screening services through partner medical practices and healthcare locations across the United States.

Onsite Mammography has not admitted any wrongdoing but agreed to a $2.525 million class action settlement to resolve the data breach class action lawsuit.

Under the terms of the Onsite Mammography settlement, class members can receive reimbursement for out-of-pocket expenses related to the data breach. This includes up to $5,000 for documented expenses, such as bank fees, credit costs, credit monitoring, identity theft expenses and more.

Class members can also receive a pro rata share of the settlement fund. Exact payments will vary depending on the number of claims filed with the settlement.

All class members can receive three years of free credit and medical data monitoring and insurance services. These services include three credit bureau monitoring and $1 million in identity theft insurance.

The deadline for exclusion and objection is July 13, 2026.

The final approval hearing for the Onsite Mammography settlement is scheduled for Sept. 9, 2026.
