Costa Rica’s public healthcare is run by the CCSS (the Caja), a single-payer social insurance fund financed by mandatory payroll or declared-income contributions, giving affiliated residents access to a nationwide network of clinics (EBAIS) and hospitals. Here is what that actually means for an American or Briton living in Costa Rica: 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
Legal residents, including Pensionado and Rentista visa holders, must register with CCSS as part of the post-approval residency process; proof of affiliation is required for DIMEX documentation and ongoing renewals. CCSS calculates a monthly contribution based on declared income or pension (reported as roughly 12-14% of the required minimum, i.e. the USD 1,000/month pensionado floor or USD 2,500/month rentista floor, though the exact 2026 rate for retirees was not confirmed from an official source). There is no UK or US reciprocal healthcare arrangement (UK S1-style deals apply only within the EEA/Switzerland), so US/UK expats pay into CCSS like any other resident.
If you are retiring here
Pensionado and Rentista retirees have no exemption: CCSS affiliation is mandatory as a condition of maintaining residency, with contributions calculated on their declared minimum pension/income regardless of employment status. Since no US/UK reciprocal health agreement exists, non-working retirees rely entirely on Caja affiliation plus voluntary private insurance for faster or higher-comfort care.
What public cover will not give you
- Specialist and elective-procedure waits commonly reported at 3-6+ months, sometimes over a year
- English-speaking providers are less consistently available in the public system
- Faster, provider-of-choice care generally requires private insurance/private hospitals
- Dental coverage under CCSS is inconsistently reported (some sources say it is included, most expat guides describe it as a gap requiring private/out-of-pocket dental care)
So do you need private health insurance?
Not legally required for residency (CCSS enrollment is the actual legal requirement), but de facto necessary for most expats who want prompt specialist access, English-speaking care, or private hospital treatment. 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.
