What this document is
C-061 (“Manifestación de disconformidad con el alta médica emitida por el INSS”) is an official form of Spain’s National Social Security Institute (INSS). With it a worker states that they disagree with the medical discharge (alta médica) issued by the INSS medical inspectorate.
The procedure covers a discharge for recovery, for improvement or for failing to attend an examination, issued by INSS after sick leave (incapacidad temporal) has lasted 365 days. A discharge from your family doctor or a mutua is challenged under different rules.
Who files and where
- the worker, their legal representative or an authorised representative;
- deadline: no later than four calendar days after notification of the discharge (art. 170.3 LGSS, RD 1430/2009, art. 3);
- filing: via the Social Security Portal de Prestaciones, a signed copy by post, or at an INSS centre (CAISS) by appointment; the law also allows filing with the health service medical inspectorate or at any public registry;
- on the day of filing or the next working day the worker must inform the employer — the form includes a separate employer’s copy for this.
What the form asks
- 1.1 — the worker: surnames, given name, DNI/NIE/passport, Social Security number, address, phones, e-mail;
- 1.2 and 1.3 — a legal or authorised representative, if the worker does not file personally;
- 2 — start date of the sick leave and who was paying the benefit at discharge: employer, mutua, SEPE or INSS;
- 3 — date the discharge was received; 4 — statements, two consents, place and date of signing, INSS province.
What to bring
- the worker’s DNI, passport, TIE or NIE and, if a representative files, their ID;
- for a legal representative — the court decision or the family book (for a parent); for an organisation — its CIF;
- for an authorised representative — proof of representation;
- optionally — recent medical reports showing you are not yet fit to work.
