For decades, getting care from a public hospital in Mexico has depended not on where you live or what you need, but on who you work for. That is about to change.
President Claudia Sheinbaum announced this week that a presidential decree will formally create the Servicio Universal de Salud — Universal Health Care — with full implementation beginning Jan. 1, 2027. The goal: any Mexican can walk into any public clinic or hospital and be treated, regardless of which institution they are enrolled with.
A System Built on Silos
Mexico’s public healthcare has long operated in parallel lanes. Private-sector workers are covered by IMSS (Instituto Mexicano del Seguro Social). Federal government employees belong to ISSSTE (Instituto de Seguridad y Servicios Sociales de los Trabajadores del Estado). Those without formal employment — roughly 40% of the population — rely on IMSS-Bienestar.
Each institution runs its own hospitals, clinics, records, and budgets. If the nearest hospital happens to belong to a different system than yours, you generally cannot be seen there. Patients mid-treatment who lose their enrollment status can have care interrupted. Transfers between institutions for emergency cases are common — and costly.
Eduardo Clark, the Health Ministry’s undersecretary for sectoral integration, put it plainly: hospitals and clinics often sit closer to a patient’s home than the facility they are technically assigned to, yet patients cannot access them due to enrollment rules.
What Changes in 2027
Starting Jan. 1, 2027, the first phase of service-sharing between institutions kicks in, with eight priority areas identified. Among them:
- Universal emergency care and uninterrupted hospitalization
- High-risk pregnancies and emergency deliveries
- Código Infarto (heart attack response) with hemodynamics services
- Código Cerebro for stroke events
- Breast cancer screening, biopsies, and treatment at the nearest unit
- Continuity of treatment for kidney failure, cancer, and transplants
- Vaccinations and primary care consultations for acute conditions
The key shift on emergencies: patients will be able to go to the nearest public hospital for urgent care and stay there through the end of their treatment, without being transferred for administrative reasons.
In the second half of 2027, specialized services — radiology, laboratory work, imaging — will begin crossing institutional lines. By 2028, the plan calls for universal prescription filling, specialist referrals, and open follow-up for chronic conditions such as diabetes and hypertension.
The ID Card That Makes It Work
None of this functions without shared data. Registration for a new universal health credential begins April 13, starting with adults 85 and older in 24 state capitals and all 16 Mexico City boroughs. The credential — issued through Bienestar offices — will eventually replace IMSS and ISSSTE membership cards and double as an official government ID.
The software underpinning the system was developed internally by IMSS and is being extended to IMSS-Bienestar, with ISSSTE and Pemex also being integrated for interoperability. No private licenses were purchased, Sheinbaum said.
A companion app will let users access a digital version of the credential, view nearby health facilities, and — by 2027 — manage appointments, review medical records, and access AI-assisted teleconsultations.
What It Means for Expats and Residents
Foreign residents with legal status in Mexico can already enroll in IMSS voluntarily, paying an annual fee that varies by age. Under the new system, IMSS enrollment would also open the door to ISSSTE and IMSS-Bienestar facilities — a significant expansion of access.
Officials have been clear that the rollout is gradual by design. Clark said the phased approach is meant to ensure the system’s financial and operational sustainability. The objective, as Sheinbaum framed it, is that by the time the current administration ends, any Mexican can receive care for any condition at any public health institution — and be received.
