Aetna International in Costa Rica
Costa Rica attracts many American retirees with its "Pura Vida" lifestyle, excellent healthcare, and proximity to the US. For US expats, Aetna International offers a key advantage: integrated US coverage. When you visit family in the States or need a US specialist, your Aetna plan works seamlessly.
Unlike other countries, Costa Rica requires all legal residents to enroll in CAJA (public insurance). Private insurance like Aetna supplements CAJA—it doesn't replace it. Most expats pay both CAJA and Aetna for comprehensive coverage.

CAJA + Aetna Strategy
In Costa Rica, CAJA enrollment is mandatory for all legal residents. You cannot skip it. But CAJA has limitations—long wait times, assigned clinics, limited English. Most expats carry private insurance alongside CAJA.
The Combination Approach
- CAJA (~$75-110/mo for Pensionado): Mandatory, covers routine care, prescriptions
- Aetna Pioneer Prime (~$220-300/mo): Private hospitals, US coverage, emergencies
- Total: ~$300-400/month for comprehensive Costa Rica + US coverage
When to Use Each
- CAJA: Routine care, prescriptions, non-urgent issues (expect wait times)
- Aetna: Private hospitals, urgent care, specialists, US trips, emergencies
Why Most Expats Keep Both
- CAJA is legally required—you can't drop it
- CAJA has long wait times for specialists and elective procedures
- Private hospitals offer faster care and English-speaking staff
- Aetna covers you in the US when visiting family
- Medical evacuation to the US if needed
Network Coverage in Costa Rica
Costa Rica has excellent private hospitals, mainly concentrated in the San José metro area.
| City | Private Hospitals | Direct Billing |
|---|---|---|
| San José | CIMA Hospital, Clínica Bíblica, Hospital La Católica | |
| Escazú/Santa Ana | CIMA Hospital, Hospital Clínica Bíblica (coming) | |
| Guanacaste | Hospital Liberia, Clínica Guanacaste | Verify |
| Caribbean Coast | Hospital Tony Facio (public), private clinics | Limited |
| Pacific Coast | Hospital Metropolitano, private clinics | Verify |
Key Hospitals
- CIMA Hospital (San José/Escazú): JCI-accredited, top private hospital in Costa Rica
- Clínica Bíblica: Oldest private hospital, excellent reputation
- Hospital La Católica: High-quality care, good for surgeries
Outside San José
Private hospital options are limited outside the Central Valley. Beach towns and rural areas have clinics, but major care often requires travel to San José. Aetna's medical evacuation coverage becomes important if you live in remote areas.
Plans and Pricing
Aetna Pioneer plans include US coverage—no add-on needed.
| Plan | Coverage | Costa Rica (Age 50) | US Coverage |
|---|---|---|---|
| Pioneer | Inpatient + Emergency | $160-220/mo | Full integrated |
| Pioneer Prime | Inpatient + Outpatient | $220-300/mo | Full integrated |
| Pioneer Platinum | Comprehensive | $300-400/mo | Full integrated |
Prices include worldwide coverage with full US access. Age 50 shown (common for Costa Rica retirees).
Plan Recommendations
- Pioneer: Hospital-only. Good if you'll use CAJA for routine care and want Aetna for emergencies and US coverage.
- Pioneer Prime: The practical choice. Includes outpatient for faster private care access.
- Pioneer Platinum: Comprehensive. Best for families or those with ongoing health needs.
Navigator Plans (Modular Option)
Aetna's Navigator plans let you customize coverage—choose core hospital coverage and add modules for outpatient, dental, and vision. Good for reducing costs while keeping essential protection.
Deductible Strategy
Costa Rican private healthcare is affordable:
- Doctor visit: $50-80
- Specialist: $75-150
- Lab work: $30-60
A higher deductible ($2,000-5,000) significantly reduces premiums. Use CAJA for routine care and save Aetna for private hospitals and US visits.
US Coverage Advantage
The main reason to choose Aetna over local insurers:
US Network Benefits
- Full Aetna US network access
- Direct billing at US hospitals
- Aetna's negotiated US rates
- No separate add-on cost
- Coverage continuity if you return
Why It Matters
- Costa Rica is close to the US (3-hour flight)
- Many expats visit family regularly
- US specialists accessible
- Medicare doesn't work abroad
- Medical evacuation to US if needed
Medicare Replacement
US Medicare doesn't cover you in Costa Rica. For American retirees, Aetna effectively replaces Medicare abroad while keeping US coverage active for visits home.
Built-In US Coverage
No surprise premiums when visiting family or needing US care.

Coverage During Residency Processing
Costa Rica residency processing takes 12-18 months. During this time:
- You cannot access CAJA (only for approved residents)
- You need private insurance for all healthcare
- Rentista visa requires proof of private insurance for the application
Pre-Residency Strategy
Start Aetna before arriving in Costa Rica. It covers you during the 12-18 month residency wait, satisfies Rentista visa insurance requirements, and continues after CAJA enrollment as your private supplement.
Who Should Choose Aetna
| Factor | Aetna International | INS (Local) |
|---|---|---|
| Monthly Cost (Age 50) | $220-300 | $80-120 |
| US Coverage | Full Aetna network | None |
| Network in Costa Rica | Good | Excellent (local) |
| Age Limit | Up to 74 | Under 70 only |
| Medical Evacuation | Included | Limited |
| Portability | Worldwide | Costa Rica only |
| Best For | US expats, over 70 | Long-term residents under 70 |
Ideal For
- US citizens in Costa Rica
- Those who visit the US regularly
- Expats over 70 (INS doesn't accept them)
- Those awaiting residency approval
- People who might repatriate
- Rentista visa applicants
Consider Alternatives
- Non-US expats (no US benefit)
- Budget-focused under 70 (INS cheaper)
- Those who never visit the US
- Permanent Costa Rica residents without US ties
Common Questions
Do I still need CAJA if I have Aetna?
Yes. CAJA enrollment is legally required for all Costa Rica residents since 2010. You cannot receive or renew your residency card without CAJA. Aetna supplements CAJA—it doesn't replace it.
Does Aetna replace Medicare in Costa Rica?
Aetna provides coverage abroad that Medicare doesn't offer. For US retirees in Costa Rica, it effectively serves as Medicare replacement for local care and provides US coverage for visits home.
Can I use Aetna while waiting for residency?
Yes. Aetna covers you immediately upon enrollment. Use it for all healthcare during the 12-18 month residency processing period before CAJA access becomes available.
Is Aetna accepted for Rentista visa applications?
Generally yes. Aetna provides comprehensive coverage that meets Rentista visa requirements. They can provide documentation confirming your coverage for the visa application.
What if I'm over 70?
Aetna accepts applicants up to age 74. This is a major advantage over INS (Costa Rica's local private insurer) which doesn't accept new applicants over 70.
