President Claudia Sheinbaum signed a historic decree on Saturday, April 11, 2026, officially establishing a Universal Health Service designed to provide comprehensive medical care to all Mexicans.
The landmark executive order initiates the unification of the nation's major public health institutions, including the Mexican Social Security Institute (IMSS), the Institute for Social Security and Services for State Workers (ISSSTE), and IMSS-Bienestar.
Under the new framework, any citizen will be eligible to receive medical attention at any public facility, regardless of their specific labor affiliation or social security contributions.
During the signing ceremony at the National Palace, Sheinbaum described the move as a fundamental shift toward treating healthcare as a guaranteed right rather than a professional benefit.
The administration announced that the first phase of the rollout will begin on Monday, April 13, with the registration of a new Universal Health Credential for citizens aged 85 and older.
This digital and physical document will eventually serve as a primary national identification and will hold the digital clinical history of each patient to streamline cross-institutional care.
While the unified system is scheduled to begin full operational exchange on January 1, 2027, the decree mandates immediate preparations for emergency care and specialized treatments.
Supporters of the reform argue that consolidation will eliminate bureaucratic overlap and create a more cost-effective system that prioritizes marginalized and rural populations.
However, opposition leaders have raised concerns regarding the fiscal sustainability of the plan, questioning if current infrastructure can withstand a significant influx of new patients.
Critics, including Deputy Éctor Jaime Ramírez Barba, warned that without a massive increase in medical staffing and hospital equipment, the policy could lead to increased waiting times.
The Sheinbaum administration has countered these claims by highlighting that 80 of 90 previously abandoned hospitals have already been brought into operation as part of the transition.
In the United States, the administration of President Donald Trump has not issued a formal statement, though regional analysts suggest the reform could influence cross-border health dynamics.
As the registration period approaches, government modules are being established across all 32 states to facilitate the issuance of the universal credentials.
The transition marks one of the most ambitious social policy shifts in Mexico's modern history, aiming for full service integration by the year 2030.
