Aetna agreed to a $3.42 million class action lawsuit settlement to resolve claims it wrongfully denied proton beam therapy (PBT) claims for prostate cancer treatment.

The Aetna proton beam therapy class action settlement benefits members, participants and beneficiaries of employee welfare benefit plans governed by the Employee Retirement Income Security Act (ERISA) and administered or insured by Aetna. Eligible individuals must have been diagnosed with localized prostate cancer, submitted a precertification request for proton beam therapy prior to the date of service and received a precertification denial between Jan. 1, 2015, and March 31, 2024, citing “experimental,” “investigational,” “unproven,” “superior,” “superiority” and/or “more effective” as the basis for the denial.

The Aetna settlement also benefits Aetna plan members who had an initially approved precertification request for PBT, received PBT for the same diagnosis code with no allowed post-service PBT benefit claims and received a denial for a post-service claim between Jan. 1, 2015, and March 31, 2024, that cites “experimental,” “investigational,” “unproven,” “superior,” “superiority” and/or “more effective” as the basis for the denial.

According to the proton beam therapy lawsuit, Aetna denied precertification requests and post-service benefit claims for proton beam therapy to treat localized prostate cancer. The plaintiff in the case argued that Aetna’s denials violated the ERISA.

Aetna is a health insurance company that offers a variety of plans to individuals, families and employers.

Aetna has not admitted any wrongdoing but agreed to a $3.42 million class action settlement to resolve the allegations.

Under the terms of the Aetna settlement, class members can receive a flat payment of $12,000.

Class members who submit proof of payment and/or proof of indebtedness for proton beam therapy treatment can receive up to $48,000.

The deadline for exclusion and objection is Oct. 3, 2025.

The final approval hearing for the Aetna settlement is scheduled for Nov. 18, 2025.

To receive settlement benefits, class members must submit a valid claim form by Oct. 3, 2025.
