The U.S. Preventive Services Task Force, the 16-member independent panel of primary care physicians and researchers whose evidence-based recommendations determine which cancer screenings, vaccines, and preventive services private insurers must cover at no cost under the Affordable Care Act, has not convened a meeting since March 2025 — a gap of more than a year. CNN reported on March 3, 2026, that the task force"has not met in a year" and that doctors are worried it is being "abandoned" by HHS. The panel's November 2025 meeting was not held due to a government shutdown; its July 2025 meeting was abruptly canceled by HHS with no explanation. The panel's March 2026 meeting — its third consecutive postponement — was canceled, a spokesperson for HHS confirmed. Five of the 16 member terms expired January 1, 2026, and have not been filled, leaving the panel with 11 active members.

Fox News reported that the House GOP Doctors Caucus — a group of physician-legislators — wrote to HHS Secretary Robert F. Kennedy Jr. backing a "major reform" of the USPSTF, arguing the panel had been prioritizing "woke distractions" and social justice considerations over evidence-based clinical medicine. The letter, cited in Fox News's coverage, argued: "Preventive care should be about keeping Americans healthy, not about checking political boxes." The GOP Doctors Caucus letter is aligned with Kennedy's broader "Make America Healthy Again" initiative, which has focused on questioning certain vaccine recommendations and medical guidelines that MAHA advocates see as influenced by pharmaceutical industry interests rather than independent science.

The Wall Street Journal reported exclusively that Kennedy was considering removing all current members of the USPSTF and replacing them with new appointees. HHS responded to the Journal by saying "no final decision has been made on how the USPSTF can better support HHS' mandate to Make America Healthy Again." The American Medical Association issued a statement expressing "deep concerns" about reported plans to overhaul the panel, warning that replacing the entire board would disrupt the evidence-review pipeline and could cause insurers to no longer be legally required to cover services that had received A or B grades under current guidelines. The AMA told CBS News that the independence of the USPSTF process has been essential to its credibility with clinicians.

The practical stakes are significant. The USPSTF typically produces 20 to 25 new clinical guidelines per year; in 2025, it released only about five. The panel's A and B recommendations — for services ranging from annual mammograms to depression screening and aspirin therapy — directly trigger no-cost-sharing coverage requirements for approximately 160 million Americans with private insurance. CNN noted that under the ACA, any change to the legal status of the USPSTF or removal of its independent authority could affect coverage for colonoscopies, lung cancer screening CT scans, diabetes prevention counseling, HIV pre-exposure prophylaxis, and dozens of other services that currently must be covered without copays.
