KFF Health News reported Medi-Cal lost almost 100,000 immigrants without legal status in the second half of 2025. State officials said it is unclear whether disenrollment is running faster than in other groups, but researchers pointed to fear of Trump administration immigration policies as the most obvious driver. If fear is suppressing enrollment, plans lose capitation and hospitals can inherit more uncompensated care. That looks less like a clean redetermination story than a coverage chill with financial spillover.

Congress returned April 13-14 with budget hearings on the White House's FY 2027 request, which would cut HHS discretionary funding to $111.1 billion, down $15.8 billion, or 12.5%. At the same time, GOP leaders are preparing a budget reconciliation bill to fund ICE and CBP by June 1 after a nearly two-month DHS shutdown and stalled bipartisan talks. Senate leaders want a narrow border package, but if the bill expands, healthcare savings could reenter the offset hunt. That keeps Medicaid, Medicare, and drug policy changes in play as scoreable pay-fors, because Washington never met a hospital-shaped piggy bank it did not admire.

CDC filed a revised ACIP charter on April 1, 2026, after last month's federal court ruling froze RFK Jr.'s reconstituted vaccine panel. The charter adds "gaps in vaccine safety research" and "recovery from serious vaccine injuries" to ACIP's remit. It also allows up to 19 voting members and lifts annual operating costs to $1.08 million from $410,000 in the 2024 charter. Because adopted ACIP recommendations drive ACA vaccine coverage and the Vaccines for Children list, payer liability and launch assumptions can move with committee process.
