Claiming medical expenses: the documents decide it

When you claim, and when you do not

Most private care in Spain never produces a claim at all. You book a provider from your insurer’s directory, the cuadro médico, showing your membership card at the desk, pay a copayment if your plan has one, and the invoice travels between the clinic and the insurer without ever passing through your hands. That flow is covered in how private health insurance works, and nothing on this page applies to it.

A claim arises in the opposite case: you paid. That happens when you used a provider outside the directory, when you were treated abroad, when a genuine emergency left no time to check anything, when the clinic could not process your card on the day, or simply because your policy is built around reimbursement rather than direct billing. Which design your policy uses is a separate question, and our guide to network versus reimbursement plans is where it belongs. This page starts from the moment a bill is already in your hand.

The Spanish term to use with your insurer is reembolso de gastos médicos: reimbursement of medical expenses. Using that phrase, rather than a translation of “claim”, tends to route you to the right form on the first attempt.

What a claimable invoice has to be

Legitimate claims are refused over the document far more often than over the treatment, so this is the part to get right at the desk rather than at the appeal. If one has already been refused, what the law gives you sets out the deadlines that run against the insurer.

A factura is a tax invoice. Spanish invoicing rules set out what it must contain: a sequential number and series, the issue date, the name or business name, address and tax number of both the issuer and the recipient, a description of the operation detailed enough to establish what was charged for, the tax rate and quota, and the date of the operation where that differs from the invoice date. Because medical assistance is exempt from VAT, a medical factura will usually carry no IVA line but should reference the exemption instead. The general relief that lets businesses skip issuing invoices for VAT-exempt work does not extend to medical assistance, which means a Spanish clinic is required to give you a proper factura when you ask for one.

A recibo is not that. A recibo is a receipt: evidence that money changed hands. So is a card terminal slip, so is the printout from a reception till. It typically shows an amount and a date and frequently nothing else: no patient name, no itemisation, no tax number for the provider. It proves you paid something. It does not prove what you paid for, or who it was for. Insurers reject on exactly that gap, and the rejection is usually correct.

The practical rule: leave every appointment with a document that names you, itemises what was done, and identifies the provider by tax number. If reception hands you anything else, ask for the factura there and then. Going back three weeks later, in a second language, to a receptionist who has never seen you, is a materially harder conversation.

The medical documentation

The invoice establishes the money. Something else has to establish the medicine. What insurers typically want alongside the factura is a document from the treating clinician saying what was wrong and what was done: an informe médico, a medical report. For a hospital stay this is the discharge report, the informe de alta. For imaging or laboratory work it is usually the request from the doctor who ordered the test, sometimes with the result.

The purpose is to let the insurer match the charge to a covered benefit and to a diagnosis. An invoice for a consultation with no indication of what the consultation was about gives the assessor nothing to assess. This is also why claims for care that ought to have been authorised in advance stall: without the authorisation reference, the assessor has no record that the insurer ever agreed to the treatment.

Claim type	Documents usually required
Specialist consultation	Factura naming you and itemising the visit; medical report or consultation note
Diagnostic test — imaging, laboratory	Factura; the referring doctor’s request showing the clinical reason; often the report on the result
Emergency or urgent care	Factura; the emergency department report; a note on why the network was not used
Surgery or hospital admission	Factura, itemised by component where the hospital bills separately; discharge report; the prior-authorisation reference
A course of treatment such as physiotherapy	Factura per course or per session as billed; the prescription or referral; the authorisation reference; often a session log
Dental treatment	Factura itemised by act performed; treatment plan or budget where the insurer asked for one first
Care received abroad	Factura and proof of payment; medical report; a translation where the insurer requires one; currency and payment date evidence

Prior authorisation is a process of its own, with its own timing, and it is covered separately in our guide to authorisations rather than re-explained here.

Submitting, and what you keep

Nearly every Spanish insurer now takes reimbursement claims through an app or a member portal, with a branch or postal route retained as a fallback. The portal route is worth using even if you dislike it, because it timestamps the submission and gives you a reference number, and that number is the difference between a disputed date and a settled one.

Photograph or scan every document before you send it, and keep the originals. Keep the payment evidence too: the card receipt or the bank transfer record, matched to the invoice. Insurers do sometimes ask for proof that the invoice was actually settled by you rather than merely issued, and that is a request you cannot satisfy retrospectively if the receipt has gone.

What “reimbursed” actually means

Reimbursement is not a refund. Three separate reductions typically sit between the invoice total and the payment that reaches your account, and they apply in sequence.

First, cover. Only costs that fall within a covered benefit count at all. Anything excluded, anything still inside a waiting period, and anything outside the policy’s geographic scope drops out before any percentage is applied.

Second, the percentage. Reimbursement policies pay a proportion of covered costs rather than all of them.

Third, and least expected, the tariff. Some policies reimburse the agreed percentage of what the insurer’s own schedule recognises for that act, not of what your clinic actually charged. Where the clinic charges above the recognised amount, the shortfall is yours on top of the percentage, and the arithmetic can look surprising.

Caps then compound all three: per act, per process, per year.

Every one of those numbers is a figure in your own documents rather than a market standard, which is why none appears on this page. Your reimbursement percentage and your caps sit in the schedule of limits attached to the condiciones particulares; whether a tariff applies, and how the recognised amount is arrived at, is defined in the condiciones generales under the reimbursement heading. Read both once, calmly, well before you are choosing a provider. If you are then told about a limit you cannot find, ask the insurer to point to where you accepted it.

Part-paid, or refused

A settlement smaller than you expected is usually one of the three reductions above rather than an error, but you are still entitled to the reasoning. Ask for the claim breakdown in writing: which invoice lines were admitted, which were not, and which clause each exclusion rests on. Vague answers are worth pushing back on; a specific clause reference is answerable, an unattributed “not covered” is not.

Where the problem is documentary, meaning a recibo instead of a factura, a missing patient name or no medical report, it is usually fixable. Go back to the provider, obtain the corrected document, and resubmit under the existing claim reference rather than opening a new one.

Two timing rules give you leverage if the process stalls. The insurer must pay the minimum amount it may owe within forty days of receiving your declaration, even while it continues to investigate the rest. And an insurer that has not performed within three months of the incident is in default, which carries an interest consequence. Neither obliges anyone to pay a claim that is genuinely outside cover, but both mean an open claim that has simply gone quiet is a matter you can legitimately chase with a date attached.

If the answer remains unsatisfactory, every Spanish insurer must operate a customer-service department that accepts formal complaints in writing, and that is the step that creates a record.
