What is the difference between INS and international health insurance?

INS (Instituto Nacional de Seguros) is Costa Rica's state-owned insurer. Its health plans are built for treatment inside Costa Rica, through the country's private-hospital networks, at generally lower premiums than international plans. International health insurance is portable across a wider geographic area — commonly worldwide excluding the USA, or including it — with higher annual limits, emergency evacuation, and higher premiums. Neither replaces CAJA, which remains mandatory for legal residents.

Can I use an INS health plan outside Costa Rica?

INS health plans are designed mainly for care inside Costa Rica. Some INS products include regional or international tiers, but coverage abroad is limited compared with a dedicated international plan: limits are lower, non-emergency procedures abroad usually need pre-approval, and residency conditions apply. For regular care outside Costa Rica, an international plan is built for that purpose.

Which is cheaper: INS or an international health plan?

Local plans such as INS are generally the lowest-priced private option because the coverage territory is one country. International plans cost more, and including treatment in the United States is the most expensive step. Exact premiums are underwritten per applicant by age, deductible, limits, and benefit options — compare policy wording, not only headline premiums.

I am a US citizen living in Costa Rica. Will an INS plan cover treatment back in the US?

Not in the way an international plan does. INS health plans are built for treatment in Costa Rica, and their international coverage is limited and conditional. US citizens who want the option of treatment in the United States — where care is very expensive — typically need an international plan that explicitly includes the USA, or keep US-based coverage such as COBRA or a marketplace plan where allowed.

Does INS cover pre-existing conditions?

Pre-existing-condition treatment depends on the insurer's underwriting decision and the policy wording. INS, like other insurers, may cover a condition, exclude it, apply a waiting period or surcharge, or decline the application. Disclose medical history accurately and obtain the decision in writing before relying on any verbal assurance.

Can private insurance (INS or international) replace CAJA?

No. For legal residents, affiliation with the Caja Costarricense de Seguro Social (CCSS, known as CAJA) is mandatory regardless of which private plan you carry. Private insurance complements CAJA but does not replace the obligation to affiliate and contribute.

INS vs International Health Insurance: Which Do Expats in Costa Rica Need?

Q: Can expats buy INS health insurance in Costa Rica?

Expats can generally apply for INS health insurance, subject to INS eligibility and underwriting rules. Independent expat guides report that applicants over 55 may need to supply additional medical information and that new coverage may not be available over age 70, so retirees should confirm current underwriting terms before planning around INS.

Q: Can I carry both INS and an international health plan?

Some expats layer coverage — for example, a local plan for day-to-day private care in Costa Rica plus an international plan for travel and treatment abroad. Whether that combination makes financial sense depends on overlap: two premiums for overlapping domestic coverage is rarely worth it, but complementary structures can be. Compare benefits side by side before doubling up.

Two very different products sit under the "private health insurance" label in Costa Rica: INS, the country's state-owned insurer, and international health plans from private carriers. This guide explains how they differ — in territory, limits, portability, and cost patterns — and how to figure out which one fits your life here.

The short version

INS (Instituto Nacional de Seguros) is Costa Rica's state-owned insurer. Its health plans are built for treatment inside Costa Rica — access to the country's private hospitals and clinics at generally the lowest private-market premiums. International health plans — issued by private carriers such as ASSA, MAPFRE, or Pan-American Life, or by global expat insurers — are built for portability: eligible care across a wider territory, commonly worldwide excluding the USA or including it, with higher limits, emergency medical evacuation, and higher premiums. Neither replaces CAJA, the public system that remains mandatory for legal residents. If you live in Costa Rica full-time and want affordable private care locally, INS-style plans are usually enough. If you travel often, split the year between countries, or want treatment back home, the international plan is doing the heavy lifting.

What INS actually is

The Instituto Nacional de Seguros is Costa Rica's state-owned insurance institution, created by law in 1924 and supervised, like every other insurer operating in the country, by the Superintendencia General de Seguros (SUGESE). For decades it held a monopoly; since the market opened in 2008 it has competed with private insurers, but it remains the largest single insurer in the country and carries a full state guarantee for its insurance activity.

In practical terms, what matters to you as an expat is this: INS issues health plans designed for the Costa Rican market. The product is built around the country's private provider network — private hospitals such as CIMA, Clínica Bíblica, and Hospital Metropolitano, private clinics, laboratories, and pharmacies. Because the coverage territory is one country, premiums are generally the lowest of the private options. One independent expat guide (ExpatFocus, checked October 2026) describes INS policies as recognized by a wide network of private providers, and notes underwriting constraints worth knowing about: applicants over 55 may need to supply additional medical information, and new coverage may not be available to expats over age 70. Confirm current underwriting terms before planning around INS — these details change, and the policy wording governs.

What "international health insurance" actually is

International health insurance is a different product family, issued by private carriers — in Costa Rica's market, names like ASSA, MAPFRE, and Pan-American Life are common on local policies — or by global expat-focused insurers. Instead of centering on one country's provider network, it centers on a territory you choose: commonly worldwide excluding the USA, or worldwide including the USA. Including the United States is the most expensive step, because US care costs drive the pricing of any plan that covers it.

The defining features are portability and higher limits. An international plan is designed so that eligible care anywhere in the chosen territory — a doctor's visit, a hospitalization, an emergency while traveling — falls under the same policy. Many include emergency medical evacuation, which is the benefit that gets you transported to adequate care (or back home) after a serious accident or illness far from a good hospital. Annual benefit limits run much higher than local plans: for reference, one 2025 comparison from Pacific Prime lists ASSA's Dominus Blue at an annual benefit limit of USD $2,000,000 and its Regius Blue at USD $1,000,000, against INS Medical's regional-tier limits commonly cited at around USD $200,000 per year. These are third-party figures, not quotes — the policy wording for any specific plan is what counts — but they show the scale of the difference.

Who actually benefits from each option

INS is usually the better fit if...

You live in Costa Rica full-time. If your healthcare happens in-country — a local doctor, the private hospital you like, routine labs — a domestic plan buys exactly that, at the lowest private premium.
Budget is the deciding factor. Because the territory is one country, INS-style plans are generally the least expensive private option. If the choice is between an INS plan and no private coverage at all, the local plan wins on affordability.
You already have CAJA and want a faster lane. CAJA remains your legal base as a resident; an INS plan adds speed, provider choice, and access to private hospitals without public-system waits. For a fuller explanation of how the two layers work together, see our guide to CAJA vs private plans.

An international plan is usually the better fit if...

You travel frequently. If your year includes months outside Costa Rica, a domestic plan leaves you uncovered most of the time — travel insurance fills emergencies only. An international plan covers you where you actually are.
You split the year between Costa Rica and another country. Snowbirds and half-year residents fall through the gap of domestic plans on both ends. Portability is the product that solves this.
You want the option of treatment back home. For US citizens especially, see the section below — US care costs make this the one case where high limits are not optional.
You want evacuation coverage. Emergency medical evacuation is a standard feature of international plans and the one benefit domestic plans do not replicate. For serious injury in a remote area, this is the benefit that matters most.
A residency or visa process requires it. Some visa categories and residency processes call for private health coverage meeting specific conditions — check the current requirement against the policy before applying.

Can you carry both?

Some expats layer coverage — a local plan for day-to-day private care in Costa Rica plus an international plan for travel and treatment abroad. Whether that combination makes financial sense depends on overlap: paying two premiums for overlapping domestic coverage is rarely worth it. The usual mistake is buying a second plan without mapping what each one actually covers first. Compare benefits side by side, in writing, before doubling up.

Portability: care outside Costa Rica, in plain terms

This is the single biggest practical difference, so it deserves its own section. INS health plans are domestic products: they pay for care through Costa Rica's private provider network. Some INS products have regional or international tiers — one expat guide describes an INS international tier covering up to roughly USD $2 million per year with reimbursement anywhere in the world — but even these come with conditions: procedures abroad typically need pre-approval, limits are lower than dedicated international plans, and residency conditions apply (one guide notes that extended absence from Costa Rica can affect eligibility). Treat international tiers on a domestic insurer as a bounded extension, not as the same thing as a portable global plan.

International plans are designed from the ground up for the opposite use case: you are covered wherever the policy's territory reaches. Doctor visit in Panama, surgery in Colombia, treatment back home in the US — if it is eligible under the policy and inside the territory, it is covered. Emergency medical evacuation moves you to adequate care when the local facility cannot provide it. The trade-off is price: portability and high limits cost more, and plans that include the United States cost the most because of US care prices.

The decision rule is simple: map where you will actually receive care. If the honest answer is "Costa Rica, all year," portability adds cost without adding value. If the honest answer includes other countries, a domestic plan is the one adding cost without value.

A note for US citizens

Americans in Costa Rica face a specific arithmetic problem. Domestic Costa Rican plans — INS included — are not built to pay US hospital bills, and US care is among the most expensive in the world. A serious illness treated in the United States can cost more than most domestic-plan annual limits several times over.

Three options cover the gap:

An international plan that explicitly includes the USA. Confirm the USA is in the territory — "worldwide" sometimes means "worldwide excluding the USA," and the exclusion is the one you would need. This is the most expensive tier, but it is the tier that covers US treatment.
Kept US coverage. Some expats maintain US-based coverage (a spouse's employer plan, COBRA, a marketplace plan) alongside their Costa Rican insurance. US Medicare, note, generally does not cover care outside the United States — it is not a substitute for coverage in Costa Rica.
Self-insuring US care. Some expats accept the risk and would pay cash for US care. Know that a single major US hospitalization can run into six figures — this is a decision to make with open eyes, not a default.

None of these choices is mandatory — Costa Rica does not require residents to hold US treatment coverage. It is a financial-planning question, and the honest answer depends on how likely you are to seek care in the US.

Where CAJA fits

Whichever private option you choose, remember the layer underneath: affiliation with CAJA (the Caja Costarricense de Seguro Social) is mandatory for legal residents and applies across categories — employees, the self-employed, retirees, and investor-visa holders. Private insurance, INS or international, complements CAJA but does not replace the obligation to affiliate and contribute. The full picture — when CAJA is mandatory, how contributions work, and the combination most long-term expats use — is in our CAJA vs private plans guide.

Practical next steps

Confirm your CAJA position first — category, contribution basis, and enrollment status. The private choice sits on top of this, not instead of it.
Draw your treatment map. Costa Rica only? Costa Rica plus regional travel? Including the USA? This one answer eliminates half the products on the market.
List the hospitals and doctors you actually want. For INS, confirm they are in the INS private network. For international plans, confirm direct-billing and pre-authorization rules in each country you named in step 2.
Compare limits against the worst case, not the routine. A plan that covers your checkups but caps out below a serious hospitalization is not insurance; it is a discount card. Annual and lifetime limits, evacuation limits, and exclusions matter more than the premium.
Read the underwriting rules before you apply. INS and every international carrier set their own eligibility terms — age thresholds, medical-information requirements, pre-existing-condition treatment. Get the decision in writing.
Check pre-authorization and direct billing before you need them. A plan that reimburses you six months later is a different product than one that pays the hospital directly. Know which one you are buying.
Get a side-by-side quote for your actual applicants. Age, territory, deductible, limits, and benefit priorities are what set the premium. There is no honest price until a quote exists for your actual situation.
