To amend title XVIII of the Social Security Act to ensure appropriate geographic adjustments to Medicare Advantage benchmarks in Puerto Rico.

HR10747, introduced on October 5, 2026, by Rep. Ruiz (D-CA) with three bipartisan cosponsors, seeks to amend title XVIII of the Social Security Act to ensure appropriate geographic adjustments to Medicare Advantage (MA) benchmark payment rates in Puerto Rico. The bill has been referred to the Ways and Means and Energy and Commerce Committees, marking an early legislative stage.

The money trail here is indirect: the bill does not authorize or appropriate any specific dollar amount. Instead, it directs CMS to revise the methodology for setting MA benchmark payments in Puerto Rico, likely resulting in higher per-member payments to insurers. This is a payment formula change, not a direct appropriation, so the fiscal impact depends on the magnitude of the adjustment CMS ultimately implements.

No convergence signals are present in the provided data; this bill stands alone as a targeted geographic fix for MA payment equity in Puerto Rico.

The structural winners are insurers with meaningful MA membership in Puerto Rico. Humana ($HUM) and UnitedHealth are the largest publicly traded MA carriers with significant presence on the island. Any upward benchmark adjustment directly increases their revenue from Puerto Rico members, though this represents a small fraction of their total MA revenue. Local insurers and Blue Cross Blue Shield of Puerto Rico (not publicly traded) would also benefit.

The legislative path remains lengthy: committee markups, House and Senate passage, and presidential action. Bipartisan cosponsorship improves odds, but early-stage bills face uncertain timelines. Investors should track committee activity for signs of momentum.
