Mexico’s President Claudia Sheinbaum has issued a landmark decree to establish a Universal Health Service, initiating a process to ensure all 120 million citizens can access any public medical institution. The first phase begins April 13 with the rollout of a new Universal Health Credential, starting with citizens aged 85 and older. This unified digital and physical platform aims to eventually streamline care across facilities like the Mexican Social Security Institute (IMSS), the Institute for Social Security and Services for State Workers (ISSSTE), and IMSS-Bienestar.

The plan marks a bold step toward equitable healthcare access, with the goal of allowing patients to seek treatment at any public hospital or clinic regardless of their specific employment-based enrollment. While registration begins this month, the full exchange of medical services between these institutions is slated to begin on January 1, 2027. By integrating services through a digital system and unified medical records, the government intends to reduce bureaucratic hurdles and improve efficiency for millions who have long faced fragmented care options.

The scale of the task is significant: Mexico’s public healthcare system serves a vast majority of the population, with facilities often operating at capacity. IMSS and ISSSTE combined cover tens of millions of workers, and merging access without expanding physical infrastructure could strain resources further.

While the April 13 start date for credentialing serves as a critical benchmark, the government has yet to release a full budgetary roadmap for addressing these capacity concerns. The policy’s ultimate success will hinge on execution over the coming years, with a key indicator being whether patient wait times and resource availability show measurable improvement as the 2027 service integration approaches.
