Health Insurance With Pre-Existing Conditions in Portugal — Which Insurers Accept You

Private Health Insurance in Portugal for Expats 2026: Getting Covered with Pre-Existing Conditions

You have a chronic condition, a managed illness, or a history that shows up on a medical questionnaire. You're moving to Portugal and you need private health insurance, either for a visa application (D7, D8, NHR) or simply because you want decent coverage from day one. And you're wondering whether any insurer will actually take you on.

The short answer: yes, but the path isn't straightforward, and the provider you choose matters enormously. Some insurers exclude pre-existing conditions outright and route you to the public system for anything chronic. Others, if you pick the right one and approach them correctly, will cover you after a waiting period, sometimes with a premium uplift, sometimes with a cap on specific treatments. The difference between a frustrating rejection and a workable policy often comes down to who you ask and how you ask.

Here's exactly how to do this in 2026.

Why Standard Insurers Often Don't Work for Chronic Conditions

The market reality first, because it saves you wasted time. Major Portuguese private health insurers like Médis and AdvanceCare have streamlined underwriting processes built around healthy applicants in their 30s and 40s. When a pre-existing condition appears on a declaration, diabetes, hypertension, a previous cardiac event, autoimmune disorders, cancer history, the default response from these standard providers is typically one of two things: a blanket exclusion of anything related to that condition, or a referral to the Serviço Nacional de Saúde (SNS, Portugal's public health system) for ongoing chronic management.

That's not illegal discrimination. Under ASF (Autoridade de Supervisão de Seguros e Fundos de Pensões) regulations, insurers cannot simply refuse to cover you outright, but they can and do impose exclusions or significantly higher premiums. For visa purposes, a policy riddled with exclusions for your primary health concern may or may not satisfy embassy requirements, it depends on the condition and how the exclusion is worded.

This is where specialist brokers become genuinely valuable, not as a nice-to-have but as the practical difference between coverage and no coverage. Brokers who specialise in expat health, Sistecon and Medal.pt among them, actively shop your situation across multiple providers and know which underwriters will negotiate rather than just stamp "excluded".

MGEN: The Most Reliable Option for Complex Medical Histories

Among expats with pre-existing conditions, MGEN consistently comes up as the most accessible serious option in Portugal, and for good reason. Their underwriting model is fundamentally different from standard Portuguese health insurers.

MGEN does not require proof of continuous prior coverage from your home country. For expats who've had gaps in private coverage, perhaps you relied on the NHS in the UK for years, or your Belgian mutuelle didn't give you a clean coverage certificate, this matters a great deal. You don't need to reconstruct your insurance history to get accepted.

The coverage structure for pre-existing conditions works in two phases. For the first 90 days, you get partial coverage: acute episodes and new conditions are covered, but treatment directly related to declared pre-existing conditions may be limited. After 12 months of continuous policy, full coverage of pre-existing conditions typically kicks in, including chronic management, specialist consultations, and hospitalisation for those conditions.

The trade-off is cost. Depending on the severity and management complexity of your condition, MGEN premiums can run 20% to 100% higher than a standard equivalent policy for a healthy applicant of the same age. A 55-year-old with well-managed type 2 diabetes might pay €1,400-€1,900/year where a healthy peer pays €900-€1,200/year. A more complex history, say, a previous cardiac procedure or active autoimmune condition, could push premiums further still.

That uplift is frustrating, but weigh it against what you're actually getting: a policy that will eventually cover your ongoing care rather than systematically excluding the things you actually need a policy for.

One practical note: MGEN's acceptance is not unconditional. The medical questionnaire must be completed honestly and in full. Conditions you declare are assessed individually; the underwriter may accept with a premium uplift, with a capped reimbursement limit on specific treatments, or with a defined waiting period. What they won't do is exclude everything and wave you through on paper just to collect your premium.

Allianz: Strong Option, If You Can Prove Continuous Coverage

Allianz takes a different approach. Their underwriting for pre-existing conditions can be quite accommodating, but it pivots on one critical requirement: documentation of continuous prior coverage from your home country with no significant gaps.

If you were covered under a UK employer health scheme, a German private Krankenversicherung, or a French mutuelle complémentaire up until your move to Portugal, and you can provide a certificate confirming that coverage was active and continuous, Allianz will often accept pre-existing conditions with a standard 90-day waiting period rather than imposing heavy exclusions or large premium uplifts. The logic is actuarial: continuous prior coverage demonstrates that your condition was being managed and monitored, reducing the insurer's uncertainty about your health trajectory.

Where Allianz works particularly well is through specialist broker channels. The expat-focused associations AFPOP (the Association of Foreign Property Owners in Portugal) and C1 (formerly Citizens Advice Portugal) have historically facilitated tailored Allianz schemes for their members, with underwriting that's more nuanced than going to Allianz directly. A broker familiar with these channels can often negotiate acceptance on conditions that would get a flat exclusion through a standard application.

The weak point: if you've had gaps in private coverage, even 6-12 months where you were uninsured or relying on a public system without a transferable certificate, Allianz's advantage disappears. Gaps trigger standard underwriting, which typically means exclusions or high uplifts on anything flagged in your medical history.

Cost comparison: where accepted with continuous coverage documentation, Allianz premiums tend to be 10-30% above standard rates for managed conditions, which is meaningfully lower than MGEN's potential uplift. For someone with good documentation and a well-controlled condition, Allianz via a specialist broker is worth pursuing seriously before defaulting to MGEN.

The Broker Strategy: How Sistecon, Medal.pt and Others Add Real Value

A point worth being direct about: for pre-existing conditions, going directly to an insurer's website or call centre is rarely the best route. The people you reach in standard sales channels follow underwriting scripts. Brokers who specialise in expat placements, Sistecon and Medal.pt being well-regarded examples in the Portuguese market, have established relationships with underwriters and know which providers are currently flexible on specific condition types.

Here's what that concretely means. A broker working on your behalf can:

• Submit your medical questionnaire to multiple providers simultaneously and get comparative underwriting decisions, premium uplifts, exclusion wording, waiting period lengths, side by side
• Negotiate exclusion wording. "Exclusion of all cardiovascular conditions" and "exclusion of treatment directly related to the 2021 stent procedure" are very different things, and brokers can push for the more specific language
• Identify which providers are currently running looser or tighter underwriting (this shifts, and brokers track it)
• Structure a policy that satisfies visa compliance requirements (typically minimum €30,000 medical coverage) even where some exclusions exist
• Access Multicare, Médis, and AdvanceCare schemes where conditions are accepted with surcharges, these do exist, they're just not the standard retail offering

The broker's fee is typically embedded in the commission paid by the insurer, you don't pay extra for the service. Given what's at stake with pre-existing conditions, this is one situation where independent brokers earn their value straightforwardly.

What Actually Changes: Waiting Periods, Premium Uplifts, and Exclusion Rules

Whatever provider you end up with, three mechanisms shape how pre-existing conditions affect your policy. Understanding them before you get a quote means you won't be caught off guard by the policy document.

Waiting Periods

Most Portuguese private health policies apply a standard 90-day waiting period for all new policyholders, pre-existing conditions or not. During this window, coverage for treatment related to known conditions is typically suspended or partial. After 90 days, newly arising conditions are fully covered. For pre-existing conditions specifically, MGEN's model extends this to 12 months before full coverage is activated. Allianz, where documentation is accepted, often stays at the standard 90 days.

What this means practically: if you need active treatment for a chronic condition in your first few months in Portugal, you may be self-paying for that treatment while your policy matures. Build this into your financial planning. Portuguese specialist consultations run €100-€200 per visit privately; chronic medication costs vary widely but are significantly subsidised through the SNS once you're registered (more on that below).

Premium Uplifts

Expect 20-100%+ above the base premium for your age bracket, depending on condition severity and how well-controlled it is. The underwriter's assessment factors in: the nature of the condition, whether it's stable or progressive, your most recent clinical markers if relevant (HbA1c for diabetics, for example), and the expected cost of ongoing management.

A stable, well-documented condition with recent normal test results will get a smaller uplift than an active or recently diagnosed condition where trajectory is unclear. It pays to gather your medical records and recent test results before applying, not to hide anything, but to give the underwriter as complete a picture as possible. Vague histories get conservative (expensive) assumptions.

Exclusions and Capped Benefits

Since 2023, ASF regulatory updates have moved the market toward more nuanced exclusion practices. One specific change worth knowing: conditions that were treated and resolved more than 10 years ago can, under new rules, be omitted from declarations in certain circumstances. If you had a health episode a decade or more ago that has shown no recurrence, discuss this with your broker, you may not need to flag it, which simplifies your underwriting profile considerably.

For active conditions, exclusions are typically condition-specific rather than blanket. "Exclusion of direct treatment costs related to Type 2 diabetes" is the norm, not "exclusion of all metabolic conditions". Capped reimbursement, for example, a €5,000/year limit on consultations and tests related to a specific condition, is another tool insurers use, which is less severe than a full exclusion and may be negotiable.

The SNS Layer: Your Practical Safety Net for Chronic Care

This point is consistently undervalued by expats who focus entirely on private coverage and miss a genuinely important resource. Once you register with the SNS and obtain your Número de Utente (SNS patient number), you gain access to subsidised medication and treatments that meaningfully reduce the cost of managing chronic conditions, even if your private policy excludes or limits those conditions.

Medication subsidies through the SNS run from 10% to 90% off the retail price, with the highest subsidies applied to treatments for serious or chronic conditions: diabetes, hypertension, cardiovascular disease,
