Sources: 13. Developments: 2. The Supreme Court of Argentina has ruled that prepaid health insurers are not required to fund imported high-cost medicines if an authorized domestic alternative is available. The ruling overturned lower-court decisions that had mandated coverage for the imported cystic fibrosis medication Trikafta. The Court found that the previous orders were arbitrary because they failed to consider the applicable legal framework and an adequate assessment of evidence. In this case, the insurer OSDE offered Trixacar, a locally produced medication authorized by ANMAT that contains the same active ingredients as Trikafta. The Court noted that while Law 27.552 guarantees coverage for cystic fibrosis treatments, the Executive Branch had vetoed provisions that would have prevented the substitution of medications prescribed by physicians. The decision emphasizes that regulatory frameworks allow health authorities to define the scope of coverage within the official medication basket. ## Timeline ### 2026-08-10: Argentina Supreme Court overturns Trikafta medication coverage ruling Argentina's Supreme Court overturned a ruling requiring OSDE to cover the imported cystic fibrosis drug Trikafta, citing improper evidence assessment and the availability of national alternatives. 5 sources. https://clstr.news/cluster/argentina-supreme-court-overturns-trikafta-medication-coverage-ruling ### 2026-08-05: Argentina Supreme Court limits coverage of imported cystic fibrosis drug Argentina's Supreme Court ruled insurers need not cover imported high‑cost drugs when a domestic equivalent exists, overturning orders to fund Trikafta for cystic fibrosis and favoring the local Trixacar. 8 sources. https://clstr.news/cluster/argentina-supreme-court-limits-coverage-of-imported-cystic-fibrosis-drug --- Cite as: Argentina Supreme Court ruling on high-cost drug coverage.
