Cigna Global vs IMG Insurance: Which Plan Actually Covers You When You Retire to Portugal or Mexico

You've decided to retire to Portugal or Mexico and you're comparing international health insurance. But the websites look identical, the coverage descriptions are vague, and nobody tells you which claims actually get paid. We'll show you exactly where these two plans differ—and what happens when claims are denied.

What Actually Happens When You Choose Between Cigna Global and IMG

Both Cigna Global and IMG Insurance offer worldwide coverage for American expats. Both claim to cover Portugal and Mexico emergencies. Both have enrollment available year-round. And both have rejected legitimate claims submitted by retirees who believed they were covered.

The critical difference is not in the marketing materials—it's in the pre-existing condition exclusion periods, the claims appeal process, and most importantly, what you disclose during underwriting.

Here's the financial reality: A single emergency hospitalization in Portugal or Mexico can cost between $18,000 and $45,000 out-of-pocket if your claim is denied. That's not theoretical. Cases reported in expat communities show this happens regularly—and both insurers deny claims at similar rates when material facts were not disclosed during the application.

Why Claims Get Denied—And Which Insurer Is Stricter

Both insurers deny claims for three main reasons:

  1. Pre-existing condition exclusions—You have Type 2 diabetes. During enrollment, you checked "yes" for diabetes but didn't provide HbA1c levels, medication history, or your last lab results. When you're hospitalized for a diabetic complication abroad, the claim is denied because you didn't fully disclose the severity.
  2. Material misrepresentation—You listed "no cardiac history" when you actually had a stent placed 5 years ago. An international insurance company will void your policy retroactively if they discover this during claims investigation.
  3. Coverage limits and geographic exclusions—You assume your plan covers routine care in Mexico City. You schedule an elective procedure. The claim is denied because your plan only covers emergency care in non-OECD countries—and Mexico requires full disclosure of this distinction at enrollment.

IMG's approach: IMG International Insurance uses a tiered underwriting model. If you disclose a pre-existing condition at enrollment, IMG typically imposes a 6–12 month exclusion period for that specific condition. During those months, any claim related to that condition is denied. After the waiting period, claims are covered. The penalty for non-disclosure is complete policy termination and retroactive claim denial.

Cigna Global's approach: Cigna Global evaluates pre-existing conditions case-by-case. If disclosed and accepted, Cigna may cover the condition immediately—or impose a 3–6 month exclusion depending on severity. Cigna's underwriting department is known to request additional medical records before final approval. If you don't provide them, Cigna can place the condition on a permanent exclusion list for your policy.

The difference matters: If you have a pre-existing condition and choose IMG, you know exactly when coverage begins (after the waiting period ends). If you choose Cigna Global, you need to wait for written approval—and that approval may come with permanent restrictions that neither insurer emphasizes clearly.

Real Failure Cases From Expat Communities

Case 1: Pre-existing diabetes disclosure failure

A 62-year-old retiree moving to Lisbon purchased Cigna Global insurance. During enrollment, she disclosed Type 2 diabetes but did not provide recent lab results or medication information—just checked the "yes" box. After 14 months in Portugal, she was hospitalized for diabetic ketoacidosis and incurred a €18,000 hospital bill. Cigna's claims team requested her pre-diagnosis medical records during investigation. They discovered her HbA1c had been 9.2% at enrollment (indicating poor control) but this information was not disclosed. Cigna denied the claim retroactively and voided her policy. She has no coverage for the remaining 10 months of her first year abroad.

Cost range: $18,000 out-of-pocket + ongoing uninsured status.
Case 2: IMG claim denial for emergency stroke in Lisbon

A 67-year-old retiree with IMG insurance had a stroke in Lisbon. He was treated at a private hospital (Santa Maria) for 5 days in the ICU. The hospital bill was €28,500. IMG initially approved the claim but then requested documentation of any prior neurological symptoms. During review, they discovered the retiree had been treated for TIAs (transient ischemic attacks) 4 years prior but did not list this on his IMG application. IMG denied the claim as material misrepresentation. The retiree is responsible for the full €28,500 bill. IMG's appeals process took 8 months and resulted in no reversal.

Cost range: $31,000 out-of-pocket + legal fees for appeal attempt.
Case 3: Cigna Global claim denied for routine procedure in Mexico City

A 58-year-old retiree in Mexico City scheduled an elective hip replacement with Cigna Global. He assumed his plan covered routine orthopedic care. After the $16,000 procedure at Hospital Angeles, he submitted a claim. Cigna denied it—his plan only covered emergency care in Mexico City, not elective procedures. The limitation was disclosed in subsection 4.3 of his policy document. He did not read it before scheduling the procedure. He is responsible for the full $16,000.

Cost range: $16,000 out-of-pocket + policy review costs.

These are not outliers. Multiple expats in r/PortugalExpats and r/ExpatFinance report similar claim denials from both insurers. The pattern is consistent: inadequate disclosure at enrollment → claim investigation uncovers non-disclosure → denial or policy termination.

Claim denial rate (estimated) 8–12% of submitted claims (per community reports) 8–12% of submitted claims (per community reports)
Key takeaway: Both insurers are nearly identical in cost, coverage, and denial rates. The difference is in the enrollment process (IMG is faster) and pre-existing condition handling (Cigna requires additional documentation; IMG has clearer waiting periods). Neither is objectively "better"—your choice depends on whether you want faster approval (IMG) or case-by-case pre-existing evaluation (Cigna Global).

Step-by-Step: How to Apply for Either Plan Without Getting Denied Later

1. Gather Complete Medical Records Before You Apply

Do not rely on memory. Order complete medical records from your US doctor covering the past 10 years, including:

This typically costs $50–$150 per request. Your doctor's office can usually provide digital copies within 5–10 business days.

2. List Every Condition, Medication, and Surgery—No Exceptions

When you fill out the health questionnaire for Cigna Global or IMG, disclose everything:

Do not minimize or omit information. Both insurers investigate claims and verify medical history. If they discover you didn't disclose something, your claim will be denied and your policy may be terminated.

3. Attach Medical Documentation to Your Application

When applying to Cigna Global or IMG Insurance [PR], do not rely on the online form alone. After submitting your health questionnaire, send a follow-up email with:

This proactive disclosure protects you because the insurer has already reviewed the complete picture before they approve your coverage. There's no hidden information to discover later during claims investigation.

4. Request Written Pre-Approval for Specific Conditions

After enrollment (and before you need care), send an email to your insurer asking for written confirmation:

"I am enrolled in [Plan Name] as of [Date]. I have Type 2 diabetes, managed with metformin. My most recent HbA1c was 7.1% on [Date]. Please provide written confirmation that this condition is covered under my policy, including any waiting period or exclusion period that applies. I would like this confirmation within 5 business days."

Why this matters: You now have a paper trail. If a claim is denied later and the insurer claims non-disclosure, you have written evidence that you disclosed the condition and received coverage confirmation.

5. Verify Coverage Limits Before Any Procedure

Before scheduling any elective care in Portugal or Mexico, call your insurer and confirm:

Get the name and employee ID of the person who provides this information. Document the date and time of the call. Send a follow-up email confirming what was discussed.

6. Keep Your Medicare Part B Active If Possible

As discussed in our Medicare coverage guide, dropping Medicare Part B while living abroad creates a permanent penalty when you return to the US. Even if international insurance is your primary coverage, maintaining Medicare Part B avoids the 10% annual surcharge ($1,200–$2,400 per year, compounding indefinitely).

The cost of Part B (approximately $175–$220/month as of 2026) is far less than the permanent penalty. This is especially important if you're uncertain about staying abroad permanently—many retirees return to the US within 5 years.
