Chile runs a dual system in which public FONASA (funded by a mandatory 7% income/pension contribution plus state subsidy for the low-income) covers roughly 85% of the population alongside competing private Isapre insurers, with the 2024 Isapre reform law (Ley 21.674) still being phased in and litigated through 2026-2027. Here is what that actually means for an American or Briton living in Chile: what the public system gives you, what it does not, and where private cover fits.
Can you use the public system?
- Working for a local employer: Yes, by paying contributions
- Self-employed: Yes, by paying contributions
- Retired or not working: Yes, by paying contributions
Employees are enrolled automatically via a 7% payroll deduction directed to either FONASA or an Isapre of their choice; self-employed residents affiliate voluntarily with FONASA or contract an Isapre, paying 7% of declared income. Affiliation requires a RUN/RUT from a granted residence permit, or a provisional NIP while a residence application is pending; those without qualifying income can register as carente de recursos (FONASA Tramo A) at a local CESFAM for free public-network access. There is no UK NHS reciprocal agreement with Chile and no US Medicare coverage overseas, so US/UK residents depend on FONASA/Isapre affiliation or private international insurance.
Waiting period: FONASA has no enrolment waiting period once RUN/NIP registration completes; Isapre plans apply carencia periods of up to 18 months reduced coverage for declared pre-existing conditions and up to 5 years exclusion for undeclared ones.
If you are retiring here
Retirees drawing a recognised pension must still pay the mandatory 7% health contribution on that pension income (capped at a 60 UF/month taxable ceiling) to FONASA or an Isapre; retirement does not exempt them. A retiree with no recognised pension income in Chile and a pending residency application can register under FONASA Tramo A (carente de recursos) at a CESFAM with passport plus proof of the pending application, renewable yearly, for free public-network access while status is regularised.
What public cover will not give you
- public waits for non-GES elective specialist care and surgery (GES covers 90 prioritised conditions as of December 2025)
- regional access variance outside Santiago
- limited English-speaking providers in the public network
- Isapre pre-existing-condition exclusions and carencias
- premium/plan uncertainty from ongoing Ley 21.674 litigation
So do you need private health insurance?
Not a strict legal requirement for a residence permit in itself, but many long-term visas require proof of health coverage, and because FONASA affiliation needs qualifying income or a carente de recursos declaration, an Isapre or international policy is often de facto necessary for new arrivals and non-working retirees, and for private-clinic quality and shorter waits. Proof of health insurance is also a condition of the main residence routes here, so most expats need a policy in place before they apply.
