Sources: 3. Developments: 2. The Mexican Social Security Institute (IMSS) has faced several instances of provider misconduct involving fraud and data privacy violations. In early August, the Secretaría Anticorrupción y Buen Gobierno (SABG) sanctioned provider Eliana Díaz Magaña, barring her from federal contracts for two years and imposing a fine. The sanction followed findings that she supplied false information regarding 120 units of Limustin Tacrolimus 1 mg, an immunosuppressant used to prevent organ rejection. By late August, IMSS permanently canceled contracts with two companies linked to Grupo Salinas, identified as NECSUS and Creaciones Tecnológicas y Digitales Jim. These companies were removed from the IMSS Provider Registry for Integrity (REPIIMSS) after investigations revealed they had transferred institutional databases to a third party, UPAX GS, for address verifications without explicit consent. An internal investigation is ongoing to determine if public officials were involved in any misconduct regarding these contracts. ## Timeline ### 2026-08-25: IMSS cancels contracts with Grupo Salinas-linked companies Mexico's IMSS has rescinded contracts with two Grupo Salinas-linked companies, NECSUS and Creaciones Tecnológicas y Digitales Jim, due to unauthorized handling of confidential institutional data. 3 sources. https://clstr.news/cluster/imss-cancels-contracts-with-grupo-salinas-linked-companies ### 2026-08-10: Mexico sanctions IMSS provider for falsified medication A provider for Mexico's IMSS, Eliana Díaz Magaña, has been fined and barred from federal contracts for two years after supplying falsified Tacrolimus immunosuppressant medication. 3 sources. https://clstr.news/cluster/mexico-sanctions-imss-provider-for-falsified-medication --- Cite as: Irregularities in Mexican Social Security Institute provider.
