Health insurance / EXPLAINER

Pre-existing conditions: planning continuity when you move

Keep medical history, policy acceptance and ongoing treatment separate.

Who this is for

People moving to Portugal with an existing health condition, or residents considering a different health insurer.

Before ending existing cover, establish what the new insurer has actually accepted. A policy issued in your name does not, by itself, show that an existing condition or a course of treatment will be covered.

Start with the move, not a product label

Make a timeline of your current cover, intended departure and the proposed start of the new contract. Beside it, keep a separate note of the questions you need answered about continuing care. There is no need to put clinical details into a general enquiry form or send them to this publication.

The useful distinction is between access to a healthcare service and payment under an insurance contract. Public healthcare registration, an insurer’s acceptance and the practical transfer of medical care are separate matters. Arrange clinical questions with the professionals responsible for your care.

Read what the insurer means by pre-existing

The definition may look at circumstances before the policy starts, not simply the date of a formal diagnosis. Ask the insurer to explain any unclear question about symptoms, investigations or previous treatment. Use its designated secure process to provide the information required under the applicable rules.

Keep the completed declaration and the written acceptance. If a broker or customer service message seems to conflict with a document, ask for the discrepancy to be resolved by the responsible entity. Avoid relying on a general statement that “expats are accepted”.

Waiting periods and exclusions answer different questions

A waiting period concerns when a benefit begins. An exclusion concerns what the benefit does not include. Passing the waiting period does not automatically remove an exclusion relating to an existing condition.

A hypothetical example: a consultation occurs several months after the policy starts, but concerns a condition excluded in the accepted terms. The elapsed time alone does not establish reimbursement. Read the relevant coverage and exclusion together.

Build a continuity check

Before making a change, ask the new provider for a written answer that corresponds to the exact product and accepted application.

  • Is the condition covered, excluded or subject to a specific written limitation?
  • Are related investigations, medicines and follow-up visits treated separately?
  • What waiting periods or authorisation requirements apply?
  • What happens if the start of your move changes?

Keep the transition documented

Do not assume that a former employer’s group policy or a policy from another country transfers automatically. Ask both providers how the proposed dates interact and when any existing arrangement ends. A quotation is not the same as a final acceptance.

Coverage of a particular condition depends on the applicable contract and circumstances. If a claim is declined, request the contractual basis and use the complaints guide to organise the documents. For medical continuity, seek advice from the treating professionals.
