Four members of Congress have introduced the Puerto Rico Medicare Advantage Fairness Act. Sponsors are Rep. Gus Bilirakis, Rep. Raul Ruiz, Rep. Darren Soto and Resident Commissioner Pablo José Hernández Rivera.^[1] The bill seeks to align Puerto Rico's average geographic adjustment with that of the U.S. Virgin Islands. It would correct a structural flaw in the federal formula used for Medicare Advantage payments.^[2] Puerto Rico receives approximately 40% less per Medicare Advantage beneficiary than the national average. The existing federal formula relies on limited fee-for-service data to calculate rates.^[3] 2026 base monthly payments are $672 per enrollee in Puerto Rico. This compares to $847 in the U.S. Virgin Islands and $1102 nationally.^[4] Benchmark rates for plans in Puerto Rico run roughly 20% below Virgin Islands levels.^[5] Approximately 96% of Medicare eligible Puerto Rico residents are enrolled in Medicare Advantage. This enrollment represents over $10 billion in annual spending.^[6] The Medicaid and Medicare Advantage Product Association of Puerto Rico stated aligning payment rates to the U.S. Virgin Islands level would add approximately $1.5 billion annually to Puerto Rico's healthcare sector.^[7]
