Overview
- An external auditor, Castillo Miranda y Compañía, declined to issue an opinion on IMSS‑Bienestar’s 2025 financial statements because it could not obtain sufficient evidence to validate reported balances and transactions.
- The auditor said it could not verify more than 103,000 million pesos of expenditures, including 91,382 million pesos reported for personnel and over 12,000 million pesos tied to reported goods and property.
- The report identified significant weaknesses in IMSS‑Bienestar’s internal control system that prevent assurance that accounts are free from material error or fraud and that transactions and balances are reliable.
- The institute reported total spending of 192,699 million pesos for 2025, roughly 27,000 million pesos above the approved budget, and the government has responded by highlighting recent hospital and service expansions.
- The refusal marks a deterioration from 2024, when the prior auditor issued a qualified opinion, and it raises calls for stronger oversight, potential legislative probes, and clearer accounting to protect services for uninsured patients.
