Secretive Group Floods CMS With Form Letters Backing Higher Medicare Advantage Payments

KFF Health News and NPR report that a dark‑money group called Medicare Advantage Majority generated at least 13,519 of 16,324 public comments submitted to the Centers for Medicare & Medicaid Services on a January proposal to keep 2027 Medicare Advantage payment rates essentially flat. The organization, which does not disclose its funders, used a template letter warning that “nearly flat” year‑over‑year federal payments would amount to benefit cuts and risk seniors’ access to doctors, then pushed it heavily through a more than $3.1 million Facebook ad blitz since September 2024. Data analysis shows roughly 83% of all posted comments used this identical language, raising concerns among money‑in‑politics watchdogs that CMS’s process is being dominated by an orchestrated astroturf campaign rather than independent public input. Insurers are lobbying hard against the proposal, which affects about 35 million Medicare Advantage enrollees and billions in federal spending, while critics argue that opaque funding and mass‑produced comments can distort how regulators perceive seniors’ views. The episode underscores how dark‑money operations and targeted social‑media ads are increasingly used to shape technical federal payment rules that have huge consequences for patients and taxpayers.
