This bill amends the Affordable Care Act to require the creation of an ACA Exchange for Puerto Rico and directs the Secretary of HHS to apply title XXVII market reforms in the territory. It also amends the Internal Revenue Code to treat Puerto Rico like a State for specified premium tax credit rules, making many residents eligible for federal subsidies.
Why it matters: Puerto Rico has been excluded from the federal Marketplace and most premium tax credits; this bill would integrate the territory into the ACA's individual market architecture, with immediate implications for coverage eligibility, insurer obligations, federal subsidy outlays, and the territory’s existing Medicaid and local insurance rules.
At a Glance
What It Does
The bill inserts Puerto Rico into section 1304(d) of the ACA, obligating an Exchange to be established in the territory, and orders HHS to apply title XXVII market reforms there. Separately, it amends section 36B of the Internal Revenue Code to treat Puerto Rico as a State for specified premium tax credit calculations.
Who It Affects
Directly affected are Puerto Rico residents seeking individual coverage, health insurers selling plans in Puerto Rico, the Puerto Rico government and health agencies, and the federal agencies (HHS/CMS and IRS) that must implement Exchange operations and subsidy mechanics.
Why It Matters
The bill removes long-standing legal and administrative barriers that have kept Marketplace subsidies out of Puerto Rico, potentially expanding coverage for low- and moderate-income residents but also triggering federal budgetary exposure and operational challenges for building a functioning Exchange in a U.S. territory.

What This Bill Actually Does
The bill performs three discrete legal moves. First, it amends the Affordable Care Act’s list of jurisdictions eligible to host an Exchange to add Puerto Rico.
That change compels the establishment of a Marketplace framework in the territory rather than leaving Puerto Rican residents outside the federal individual market structure. Second, the bill directs the Department of Health and Human Services to apply the health insurance market reforms found in title XXVII of the Public Health Service Act to coverage offered in Puerto Rico, explicitly overriding the 2014 administrative letter that previously limited application of those provisions in the territory.
Third, it changes the Internal Revenue Code so Puerto Rico will be treated like a State for certain premium tax credit provisions; that makes many resident households eligible to receive federal premium subsidies when buying qualified coverage through the Exchange.
Operationally, the statute fixes a time horizon for change: the Exchange rules and the title XXVII reforms take effect after a 12-month implementation window. The tax-code amendment likewise applies to months beginning on or after that same implementation horizon.
The practical consequence is a phased rollout: agencies and the territorial government will have a limited window to stand up enrollment systems, arrange plan offerings, and align local regulations with federal market rules.The bill is narrow in scope—its tax-code change references specific subsections of section 36B rather than blanket tax parity—so it brings Puerto Rico into key subsidy calculations and eligibility rules but does not explicitly modify Medicaid financing, the territory’s FMAP arrangements, or other ACA mechanisms such as cost-sharing reductions, the individual mandate repeal consequences, or certain employer mandate enforcement details. That selective approach creates implementation frictions: federal subsidy payments will flow to residents who enroll, but the interaction with Puerto Rico’s existing public programs and insurer risk pools requires regulatory action and administrative coordination.
The Five Things You Need to Know
Section 2 amends 42 U.S.C. 18024(d) to add Puerto Rico to the jurisdictions required to have an ACA Exchange, with implementation due 12 months after enactment.
Section 3 requires HHS to apply title XXVII (the ACA’s market reforms) to health insurance sold in Puerto Rico, explicitly overriding a 2014 CMS letter that withheld those provisions from the territory.
Section 4 amends IRC §36B by inserting a new subsection treating Puerto Rico as a State for specified premium tax credit provisions—targeting the rules that determine eligibility and calculation of the credit.
The tax-code change takes effect for months beginning on or after the 12-month post-enactment date, aligning subsidy availability with the Exchange and market-reform timetable.
The bill is limited in scope: it addresses Exchanges, market reforms, and certain premium credit rules but does not change Medicaid matching, block-grant arrangements, or broader territory-specific federal funding formulas.

Short title
Designates the legislation as the 'Puerto Rico Affordable Care Act of 2025.' This is purely nominal but useful for statutory citation and rulemaking references that will follow implementation.
Require an Exchange in Puerto Rico
This provision inserts Puerto Rico into the ACA’s list of jurisdictions where an Exchange is to be established. The operative date is tied to a 12-month delay, giving federal and territorial actors a limited planning window. Practically, the insertion forces either a territory-run Exchange consistent with ACA rules or a federal fallback Exchange if Puerto Rico does not build an acceptable marketplace infrastructure.
Apply TITLE XXVII market reforms to Puerto Rico
The bill requires HHS to apply title XXVII of the Public Health Service Act—which includes guaranteed issue, community rating, essential health benefits, dependent coverage rules, and limits on preexisting condition exclusions—to plans offered in Puerto Rico starting after the implementation delay. It also nullifies the prior administrative interpretation (the 2014 CMS letter) that had limited the reach of those requirements in the territory, placing regulatory authority squarely with HHS to execute the change.
Treat Puerto Rico as a State for specified premium tax credit rules
This section adds a new subsection to §36B that treats Puerto Rico like a State for particular subparts of the premium tax credit statute (specifically the subsections listed in the bill). The change is narrowly targeted to certain eligibility and calculation provisions and becomes effective for months beginning on or after the 12-month post-enactment date, synchronizing with the Exchange and market-reform sweep-in.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Low- and moderate-income residents of Puerto Rico — They gain eligibility for premium tax credits and access to plans sold through an ACA Exchange, which can substantially lower monthly premiums and out-of-pocket costs for households previously excluded from federal subsidies.
- Individuals with preexisting conditions in Puerto Rico — Application of title XXVII brings federal protections such as guaranteed issue and community rating, preventing insurers from denying coverage or imposing rate-setting based on health status.
- Health care providers in Puerto Rico — More insured patients should reduce uncompensated care and improve revenue predictability, particularly for clinics and hospitals that serve large numbers of uninsured patients.
- Federal and territorial marketplaces administrators — Agencies and contractors with expertise in exchange operations stand to gain new implementation, enrollment, and plan management work as the Exchange is built and run.
Who Bears the Cost
- U.S. Treasury / Federal budget — Premium tax credits and any federal administrative costs for establishing a federal Exchange or providing federal support will increase federal outlays relative to the current baseline where the territory receives limited subsidy flows.
- Insurers offering plans in Puerto Rico — They must comply with federal market reforms, revise underwriting and rate filings to meet community rating and essential-benefit standards, and participate in risk adjustment mechanisms once applied.
- Puerto Rico government and agencies — The territory must coordinate implementation, adjust local regulatory frameworks, and may face transitional administrative and budgetary pressures despite federal subsidies benefiting residents.
- Employers with Puerto Rico employees — Changes in subsidy eligibility and possible interactions with employer-offer rules could alter employer-sponsored plan dynamics and administrative obligations, depending on how IRS enforcement and applicability are interpreted.
Key Issues
The Core Tension
The bill pits two legitimate policy aims against each other: expanding federal-market protections and subsidies to Puerto Rico to reduce uninsured rates versus the fiscal, administrative, and sovereignty implications of extending state-like ACA mechanisms to a U.S. territory that operates under distinct Medicaid funding and local health-financing arrangements.
The bill solves an access problem—exclusion of territory residents from Marketplace subsidies—by using statutory insertions and a targeted tax-code change, but it leaves several material implementation questions open. It does not amend Medicaid financing for Puerto Rico, which operates under a capped funding structure that differs from states; that means substantial populations could still fall into coverage gaps unless local programs are reconfigured or additional federal action follows.
The statute also limits the tax parity to enumerated subsections of §36B; other tax and ACA-linked mechanisms (for example, employer-reporting nuances or cost-sharing reduction mechanics) may not automatically apply, producing inconsistent outcomes that require regulatory clarification.
Operationally, standing up an Exchange in Puerto Rico is more complex than flipping a switch. The territory needs plan management, an IT enrollment platform, consumer assistance networks (in Spanish and culturally attuned formats), and regulatory alignment for network adequacy and provider reimbursement standards.
If Puerto Rico fails to establish an acceptable marketplace, HHS may need to run a federal Exchange there—triggering decisions about federal staffing, vendor contracts, language access, and whether federal risk adjustment and reinsurance programs will be extended to territorial plans. Finally, the fiscal impact is front-loaded toward federal subsidy payments and potential insurer rate re-pricing, while savings from reduced uncompensated care accrue more diffusely to providers and local budgets, creating timing and allocation frictions.
