Gov. Tony Evers on Thursday signed "Gail’s Law" at the Wisconsin State Capitol, a bipartisan measure that requires health insurers, including BadgerCare, to cover medically necessary supplemental breast screenings for people with dense breasts or other elevated risk factors. The move follows years of pressure from the Zeamer family and health advocates who warned that standard mammograms can miss cancers hiding in dense tissue. Backers say the law strips away a major financial hurdle to MRIs and ultrasounds that can catch cancer earlier, when it is far more treatable, as reported by FOX6 Milwaukee.
What Gail's Law Requires
The law requires health insurance policies, including the state Medicaid program, to fully cover medically necessary supplemental breast screening or diagnostic breast examinations for people with heterogeneously or extremely dense breasts or who are at increased risk of breast cancer, according to FOX6 Milwaukee. It defines supplemental screening to include breast MRI and breast ultrasound and defines diagnostic exams to include MRI, ultrasound, breast tomosynthesis and diagnostic mammography. Insurers may not impose cost-sharing for any diagnostic exam or for the first supplemental screening in a policy year, though cost-sharing is permitted for subsequent supplemental screenings in the same year, as reported by WisPolitics. The act will take effect the first day of the fourth month after publication and will generally first apply to plan years that begin January 1 after the act takes effect.
How the Bill Cleared the Capitol
After some earlier stumbles in past sessions, the measure sailed through this time, passing the Senate 32–1 last fall and the Assembly unanimously in mid-February, with Gail Zeamer’s family watching from the gallery, as reported by the Milwaukee Journal Sentinel. Advocates say the lopsided votes reflected an unusually broad coalition of physicians, patient groups and lawmakers who argued that expanding coverage would boost early detection and cut down on advanced-stage diagnoses.
A Personal Campaign
The bill is named for Gail Zeamer, a Neenah woman who spent years pushing for denser-breast protections after a tumor was missed on a routine mammogram. Zeamer received a clear mammogram in 2016 just a week before she was diagnosed with advanced breast cancer, and she died in 2024, according to advocacy accounts and local reporting. Her efforts helped win a 2018 law that requires doctors to notify patients about breast density, and her husband and daughters kept pressing lawmakers this session until the measure landed on the governor’s desk, according to those same advocacy accounts.
Why Doctors Back It
Physicians and radiology groups say dense breast tissue can effectively hide cancers on mammograms and that supplemental MRI or ultrasound can significantly improve detection for people at higher risk, a point underscored by the American Cancer Society’s guidance on breast density. Local medical organizations, including the Wisconsin Radiological Society, testified in support of the bill, arguing that broader coverage will let clinicians follow their medical judgment instead of forcing patients to weigh needed imaging against steep out-of-pocket costs.
What This Means For Wisconsin Women
Supporters say the new law removes a common reason patients walk away from recommended follow-up imaging and could lead to earlier treatment for cancers that might otherwise be caught only at a later, more dangerous stage. The Wisconsin Breast Cancer Coalition estimates nearly 6,000 women in the state will be diagnosed with breast cancer each year. Insurers and employers now have several months to update plan documents and adjust coverage; if a policy is tied to a collective bargaining agreement, the law’s start date for that plan can be pushed back until the contract is renewed. Patients who are unsure how or when supplemental screenings will be covered are urged to check with their health plan or provider for specifics. Advocates say the Zeamer family’s persistence has carved out a lasting legacy for breast screening access in Wisconsin, according to the Wisconsin Breast Cancer Coalition.
