If you don’t yet have international medical insurance, this article can help you make a smarter choice before you fly. If you already have a policy, it can help you verify whether what you’re holding actually covers treatment in China — a question many policyholders only think to ask after a claim gets denied. We compare six insurers most commonly seen among the international patients we coordinate: Cigna Global, Bupa Global, Allianz Care, AXA Global Healthcare, MSH China, and GeoBlue. We do not sell insurance, do not earn commission from any of these carriers, and have no financial relationship with them — so the comparison here is the same one we’d give a friend.

Six Concepts You Need to Understand Before Choosing

Before comparing carriers, you need a working grasp of what makes one policy genuinely usable in China and another one a piece of paper.

1. China-inclusive coverage. Many domestic-issued policies in your home country simply exclude overseas treatment. Even within international policies, the “Country of Treatment” schedule sometimes excludes China from the standard region — you have to buy an upgraded geographic tier. This is the first thing to verify, not assume.

2. Direct billing vs reimbursement. Direct billing means the hospital sends the bill to the insurer and you don’t front the money. Reimbursement means you pay first and claim back. The difference for a USD 90,000 CAR-T treatment is the difference between presenting an insurance card and wiring USD 90,000 from your personal account. Both can ultimately cost you the same; the cash-flow burden is not the same [1].

3. Pre-existing condition clauses. Almost all international policies treat pre-existing conditions cautiously — some exclude them entirely, some accept them after underwriting, some impose a moratorium period (typically 24 months from policy start). If your treatment is for a condition diagnosed before you bought the policy, this clause is the single biggest determinant of whether you’ll be paid.

4. Annual benefit limits. A “USD 1 million annual limit” sounds large until you map it against a transplant (USD 90,000–140,000 in China alone, multiples of that elsewhere), a course of CAR-T (USD 60,000–90,000), or proton/heavy-ion therapy (USD 45,000–60,000). Check that the limit is comfortably above your worst-case scenario.

5. Exclusions. Standard exclusions across most international policies include experimental therapies, fertility treatment, cosmetic surgery, dental beyond emergency, and certain new drugs not yet approved in your country of residence. Read the exclusions list more carefully than the benefits page.

6. Waiting periods. Cancer coverage frequently has a waiting period of 6–12 months from policy start, sometimes longer. Maternity, mental health, and certain pre-existing conditions can have separate, longer waiting periods. Buying a policy after a diagnosis usually does not work.

The Six Carriers Most Commonly Used by International Patients in China

The table below summarizes the structural fit, not a buyer’s recommendation. Specifics change every plan year and every policy tier; treat this as a starting point for your own due diligence with a broker.

Insurer Annual limit (USD) China direct-billing network Pre-existing condition handling Best fit for
Cigna Global [2] 1M / 2M / Unlimited tiers Solid coverage of major IMDs in Beijing, Shanghai, Guangzhou Some accepted after underwriting Multinational employees, long-term expats
Bupa Global [3] 2M / Unlimited tiers Solid coverage at major international and private hospitals Some accepted after underwriting High-net-worth families, long-term residents
Allianz Care [4] 1.5M / Unlimited Solid in major Chinese cities Strict European, Middle East, Southeast Asian patients
AXA Global Healthcare [5] 1.5M / Unlimited Moderate network Some accepted after underwriting European and Asia-Pacific patients
MSH China [6] 1M / 2M Strongest domestic Chinese network Strict Expats already living in China
GeoBlue [7] 1M / Unlimited Moderate, leveraging Blue Cross Blue Shield global network Strict US residents

Matching the Policy to Your Profile

Long-term expat already living in China. MSH China typically offers the deepest local direct-billing network — the practical advantage shows up at smaller hospitals and clinics outside the top international medical departments. Cigna Global is a strong second choice with broader global portability.

Short-term medical traveler (one-off 3–6 month treatment). Cigna Global Silver or Gold, or Bupa Global Comprehensive, are common picks. The non-negotiable is making sure both “China inpatient” and “China outpatient” are included in the geographic schedule.

US resident traveling to China for treatment. GeoBlue, which sits on the Blue Cross Blue Shield network, is the default starting point. Most US domestic plans (Aetna, UnitedHealth, Anthem) do not cover overseas treatment at all — you’d need a separate international policy. Cigna Global is the most common alternative.

High-net-worth family with major treatment expected (oncology, transplant, complex surgery). Bupa Global Premier with the unlimited annual limit removes the worry of hitting a cap mid-treatment. Premiums are correspondingly higher.

Middle East or Gulf-region patient. Allianz Care and Bupa Global both have mature direct-billing networks across the region with smooth handoff to international hospitals in China.

The Four Clauses That Quietly Decide Whether You Get Paid

Even within a “good” policy, four contract elements tend to be the deciding factors on contested claims.

1. Pre-authorization required. Many major treatments require written authorization from the insurer before they begin, even when you intend to pay out of pocket and claim later. Skip this step and reimbursement can be capped at 50–80% of the bill. The pre-authorization window itself can take 5–10 business days, which is a planning constraint for urgent treatment.

2. Reasonable and Customary (R&C) limits. Insurers reserve the right to disallow a charge as “above reasonable and customary rates” — which gets interesting in China, where the prices are often dramatically below R&C benchmarks set on US data. In China this usually works in your favor, but the clause cuts both ways.

3. Medical Necessity. Insurers can challenge whether a specific test, drug, or procedure was clinically necessary. This is the most common reason for partial denial we observe. The defense is a well-written Letter of Medical Necessity from your treating physician, which Chinese hospital international departments will issue when asked.

4. Country of Treatment schedule. Some policies cover “worldwide except USA,” some “worldwide except USA, Canada, Switzerland, Hong Kong,” some are geographic-region-limited. China is not always implicitly included even in “Asia” tiers. Read the exact schedule, not the marketing copy.

Policy Selection Checklist

Before you sign a new policy or renew an existing one for the purpose of treatment in China, get written confirmation from your broker or the insurer on each of these:

  1. Is China on the included Country of Treatment list at this premium tier?
  2. Are the specific hospitals you’re considering — by name — on the direct-billing network?
  3. Is the annual limit at least 1.5 times your worst-case expected total treatment cost?
  4. How are pre-existing conditions handled at underwriting, and is the condition you may seek treatment for excluded?
  5. What is the waiting period for the relevant treatment category, and has it elapsed?
  6. Are experimental or investigational therapies excluded? What about specific cell therapies (CAR-T) or radiation modalities (proton, heavy ion)?
  7. Is emergency medical evacuation and repatriation included? What about repatriation of remains?
  8. What is the pre-authorization turnaround time, and what’s the late-notification penalty?

Where MedCareInChina Sits in This

We do not sell insurance and do not earn commissions from any carrier. We are not insurance brokers. What we can do, and routinely do, is:

  1. Read your existing policy with you and tell you what it actually covers for the treatment you’re considering.
  2. Help you understand whether direct billing will work at your target hospital, or whether you should plan for self-pay and reimbursement.
  3. Coordinate with the hospital’s international department to issue the bilingual records, itemized bills, and Fapiao you’ll need.
  4. Brief the treating physician when a Letter of Medical Necessity will be needed for your claim.

What we do not do, and have never offered to do:

  1. We do not file claims with your insurer on your behalf.
  2. We do not negotiate denials with your insurance company.
  3. We do not act as your insurance broker.

If you don’t currently have an international policy and want a recommendation tailored to your nationality, age, family situation, and expected treatment, talk to a regulated international medical insurance broker in your country of residence. We can suggest broker categories to look for; we cannot quote or place insurance for you.

Action Checklist

  1. Identify your current policy carrier, plan tier, and annual limit. Pull the Certificate of Insurance — not just the marketing brochure.
  2. Walk through the eight-point selection checklist above for your existing or candidate policy.
  3. If gaps exist (no China coverage, insufficient limit, pre-existing exclusion), evaluate whether to upgrade or purchase a supplementary policy before treatment.
  4. Complete pre-authorization at least 60 days before your planned treatment start date.
  5. Confirm in writing with your insurer which hospitals are in network for direct billing.
