Full Analysis
On October 22, 2026, Resident Commissioner Pablo José Hernández (D-PR) introduced HR10874, the Medicare Low Income Subsidy Equality Act of 2026. The bill was referred to the Committees on Energy and Commerce and Ways and Means. It aims to amend titles XVIII and XIX of the Social Security Act to include residents of US territories (Puerto Rico, Guam, US Virgin Islands, etc.) in the definition of 'State' for the Medicare Part D Low-Income Subsidy (LIS) program. Currently, low-income beneficiaries in territories are excluded from premium and cost-sharing subsidies available to residents of the 50 states and DC.
The bill does not authorize new spending; it expands eligibility for existing subsidy programs. If enacted, CMS would be required to calculate and disburse additional subsidy payments to Part D plan sponsors in territories for eligible low-income enrollees. The money trail flows from the federal government (CMS) to insurers offering Part D plans in those markets. The Congressional Budget Office would likely score the cost as relatively small, given the limited population of territories (approximately 3.3 million in Puerto Rico, with a subset of Medicare-eligible low-income individuals).
No related signals or procurement actions were identified in the provided data, so this bill stands alone as a targeted equity fix. The legislative coalition includes bipartisan cosponsors (Del. Moylan, R-GU, and Rep. Soto, D-FL), but the primary sponsor is a non-voting delegate, which may limit momentum. The bill is in the earliest stage, with no committee hearings scheduled.
Structural winners are insurers with Part D exposure in territories. Triple-S Management is the pure-play beneficiary, deriving a significant portion of its revenue from Medicare Advantage and Part D in Puerto Rico. Humana ($HUM) also operates in territories but has a much larger diversified Medicare business, so the relative impact is negligible. Other large insurers like UnitedHealth Group ($UNH) have minimal exposure and are not included due to low confidence in material impact.
The timeline is uncertain. The bill must pass both committees, the full House, the Senate, and be signed by the President. Given the early stage and narrow scope, passage is not imminent. Investors should monitor committee activity and CBO scoring for signs of progress.

Stock impact
Humana ($HUM) operates Medicare Part D plans in Puerto Rico and other territories. The bill increases subsidy revenue for its low-income enrollees in those markets, but these territories represent a very small fraction of Humana's total Medicare business (which is predominantly in the 50 states). The impact on overall revenue is minimal.
