Key points
- Argentina runs a mixed system in three sectors — public, social security (obras sociales) and private — strongly interconnected through contracting, in a federal country where the provinces run public services.
- Public hospitals provide care on demand and act as the safety net for the whole population, maintaining a flow of free care even for people insured elsewhere.
- Obras sociales are around 300 union- and occupation-based funds covering formal workers; the Compulsory Medical Plan (PMO) sets the minimum services they and the private prepagas must cover, and the Health Services Authority (SSS) supervises compliance.
- Households paid 24.5% of health spending out of pocket in 2023 (WHO Global Health Expenditure Database).
- Life expectancy at birth was 77.2 years in 2023, and health spending was 10.3% of GDP in 2023 (WHO Global Health Estimates; World Bank, WHO Global Health Expenditure Database).
Direct answer: Argentina runs a mixed system in three sectors — public, social security (obras sociales) and private — in a federal country where the provinces run public services. Public hospitals provide care on demand and act as the safety net for the whole population, maintaining a flow of free care even for people insured elsewhere. Around 300 union- and occupation-based obras sociales cover formal workers, and the Compulsory Medical Plan (PMO) sets the minimum services they and the private prepagas must cover. Households paid 24.5% of health spending out of pocket in 2023. Life expectancy at birth was 77.2 years in 2023 — and healthy life expectancy 66.4 years — and health spending was 10.3% of GDP in 2023 (WHO Global Health Estimates, October 2026; World Bank, WHO Global Health Expenditure Database).

How the system works
Argentina is a federal democracy of 23 provinces, the autonomously governed Federal Capital and some 1,600 municipalities, and the health system reflects that: the provinces have not vested health care in the national government, and the system consists of three large sectors — public, private and social security — with the last two strongly interconnected through the contracting of services. The Ministry of Health sets general policies, and the provinces are responsible for public health services delivery.
The public sector is the safety net. Public hospitals provide coverage to the population on demand and, in fact, act as reinsurance for the obras sociales, since they maintain a flow of free care for the insured population. The social security sector is run by the obras sociales: around 300 entities of varying scope and size, organised by union or occupation, covering formal workers and their families. Their number fell from 312 in 1994 to 275 in 1999 as deregulation took hold. Since Decree 9/93, beneficiaries can freely choose their obra social, and Decree 84 of 1997 allows them to change once a year; retirees are free to choose as well. The largest entity in the system is the Social Services Administration for Retirees and Pensioners — PAMI, the National Institute of Social Services for Retirees and Pensioners (INSSJP).
The Health Services Authority (SSS), established by Decree 1615/96 under the Ministry of Health, oversees the obras sociales, checks compliance with the Compulsory Medical Plan (PMO) — the minimum set of services all obras sociales and prepagas must cover — and guarantees system quality and coverage. The private sector is made up of prepaid medicine companies (prepagas) under Law 26,682, while the obras sociales operate under Law 23,660 and the National Health Insurance Law 23,661.
Who pays, and what people pay
General taxation pays for the public sector, mandatory payroll contributions pay for the obras sociales, and premiums pay for the prepagas. Government and compulsory schemes accounted for 60.2% of health spending in 2023 (World Bank, WHO Global Health Expenditure Database). What patients pay is the margin outside the public sector and the PMO: households paid 24.5% of health spending out of pocket in 2023, and private spending made up the rest.
What is free, and what is not
Free at the point of use: public hospital care, on demand, for the whole population — the public hospitals are the safety net for people without other cover and for insured people whose fund does not pay. The PMO also guarantees a minimum set of services from every obra social and prepaga. What is not free is the margin: medicines and services outside the PMO, private consultations and hospital rooms, and the premiums and co-payments of the prepagas — which is what the 24.5% out-of-pocket share pays for.
How it compares
Argentina spends 10.3% of GDP on health (2023), above the OECD average of 9.3% (2024), and its life expectancy of 77.2 years is 3.9 years below the OECD average of 81.1 years (2023). Argentina is not in the OECD tables, so its figures come from WHO and World Bank sources for 2023 rather than the OECD’s 2024 dashboards. Its distinguishing feature is the three-sector fragmentation: a public sector that acts as reinsurance for union-run funds, with the PMO as the common floor — and a private market sitting alongside rather than replacing either.

Frequently asked questions
Is healthcare free in Argentina?
Public hospitals provide care free at the point of use, on demand, and act as the safety net for people without other cover — but households still paid 24.5% of health spending out of pocket in 2023.
What is an obra social?
A union- or occupation-based social security fund that manages health cover for formal workers and their families, funded by mandatory payroll contributions; there are around 300 of them, and beneficiaries can freely choose among them and change once a year.
What is PAMI?
The National Institute of Social Services for Retirees and Pensioners (INSSJP), the largest obra social, covering retirees and pensioners.
