Why this hasn't landed yet
The rule is a contract-year amendment to existing CMS regulations, which means it reads like a technical update rather than a policy reversal — and the $18.6 billion figure requires understanding the Star Ratings bonus structure before it becomes legible as news.
What happens next
Advocacy groups will spend the next 18 months documenting whether the new network adequacy and formulary access requirements produce measurable access gains — the same work they did after the CY2024 behavioral health standards, which were added the same year other network standards were quietly loosened.
The catch
Insurers already demonstrated in prior cycles that they can game specific metrics by selectively reminding doctors before sampling windows, so adding new access requirements without an auditing mechanism gives plans a familiar surface to optimize against rather than a genuine standard to meet.
