Overview

• National enrollment will begin in January 2026, with every resident receiving a health credential for the new Registro Nacional de Salud.
• People without IMSS, ISSSTE or IMSS-Bienestar affiliation will also obtain the Credencial del Bienestar to be recognized within the system.
• Sharing of medical histories across institutions will occur only with each person's consent to protect patient data.
• The registry will underpin a national health census and create initial digital medical histories for older adults.
• The rollout builds on ongoing investments and logistics reforms, including 31 new hospitals and 12 family medicine units in operation this year and reported medicine supply at 97% in IMSS and ISSSTE and 92% in IMSS-Bienestar despite supplier noncompliance.
