Overview

• National registration will begin in January 2026, issuing a health credential to all Mexicans, including those not currently affiliated with a public insurer.
• A single database will allow IMSS, ISSSTE and IMSS‑Bienestar to share patients’ medical histories with explicit consent to speed access to care.
• The government’s goal for 2027 is for many conditions to be treated at any public facility regardless of institutional affiliation.
• Officials highlight groundwork that includes an IMSS electronic clinical record, logistics and digital procurement upgrades, and at least 31 new hospitals plus 12 family medicine units in operation with 20 more hospitals starting, representing investment above 90 billion pesos.
• Operational risks persist as authorities report medicine availability near 97% at IMSS/ISSSTE and 92% at IMSS‑Bienestar while citing supplier noncompliance, and experts warn the unification will require equitable financing, unified benefits and consistent quality across institutions.
