C-096 — application to refund necessary medical treatment paid in another EU country

C-096 is a form of Spain’s National Social Security Institute (INSS): a claim to refund necessary medical treatment (tratamiento necesario) that a person insured in Spain paid for themselves during a temporary stay in another country.

According to the Social Security website, you can claim if you needed medical care while in an EU country, Iceland, Liechtenstein, Norway, Switzerland or the United Kingdom and had to pay all or part of it — even with the European Health Insurance Card (TSE) or a CPS certificate. If you could not get the refund in the country of stay, you can claim it after returning to Spain.

• the person insured in Spain (titular); if a family member was treated, the “persona asistida” section is filled in too;
• instead of the insured person, a legal representative or a former spouse entitled after judicial separation or divorce may apply;
• the paper form with the original invoices is filed at a CAISS office by appointment;
• you can also apply online through the service at prestaciones.seg-social.es, linked from the Seguridad Social page.

Insured person’s details: surnames, given name, date of birth, DNI/NIE/passport, Social Security number, phone, e-mail, address and purpose of the trip. If needed, the patient’s and the applicant’s details. Then: dates, town and country of treatment, amount paid and currency, which originals are attached, why you had to pay, IBAN for the refund, two consents, place and date of signing, INSS provincial directorate.

• original invoices: doctor, hospital or clinic, prescriptions priced by the pharmacy, other services;
• proof of payment: a bank statement or an invoice stamped as paid;
• DNI, or for foreigners a passport or national ID together with the TIE or the EU citizen registration certificate;
• if someone other than the insured person applies — proof of representation or the divorce judgment (notarial agreement).

1. Tell the chat in any language where and when you were treated, how much you paid and who was treated.
2. The assistant fills in the form in Spanish capitals and splits the IBAN into the boxes and the signing date along the line.
3. Download the PDF, sign it and take it to a CAISS office with the original invoices.
