Baja Médica Online in Spain: What a Doctor Can and Cannot Issue Remotely

Pablo works in a logistics office in Alcalá de Henares. On Sunday night he is up four times with vomiting and cramps, and by Monday morning he cannot stand upright for more than a minute. He does the sensible thing and phones the centro de salud at eight. The line is engaged. He tries again at 08:20 and gets an appointment for Wednesday. His supervisor, who is not being cruel, sends a message asking him to send "the baja" by end of day, because that is what the company's absence policy says.

So Pablo does what most people do at that point. He searches for baja médica online, finds a handful of websites promising a sick note in fifteen minutes, and gets ready to pay one of them. This is the part where things usually go wrong — not because remote medicine is unhelpful, but because the document he is about to buy is almost certainly not the document his employer's HR system is actually expecting.

Need to speak to a doctor today? Choose an appointment time that suits you and a licensed physician joins at that exact slot — no queue, no waiting on hold. Book a consultation, or have a look at the full range of consultation types first if you're not sure which one fits.

What follows is the honest version. It is less convenient than the marketing copy on some telemedicine sites, and it should save you a real amount of trouble.

(A note on this article: Pablo, Nuria and Andrés below are illustrative composites, not real patients — used to show how the process actually plays out. Everything else is drawn from how the Spanish system is structured, with links to official sources where relevant.)

The vocabulary problem behind almost every mistake

Spanish sick-leave paperwork uses at least four terms that English speakers, and plenty of Spanish speakers, collapse into one word. They are not interchangeable, and the entire question of what can be done online depends on telling them apart.

La baja médica — properly the parte médico de baja por incapacidad temporal — is an administrative act of the Spanish social security system. It opens a period of temporary incapacity (IT), triggers the payment mechanism for statutory sick pay, and exists as a data flow between the health service, the Instituto Nacional de la Seguridad Social (INSS) and your employer. It is not a letter. It is a state record.

El justificante médico is a simple document confirming you attended a consultation, and sometimes that you were advised to rest. It has no social-security effect whatsoever. Its entire function is to satisfy an employer that your absence had a medical reason.

El informe médico is a clinical report: what you presented with, what the doctor found, the assessment, and the recommended treatment. It's written for clinical purposes rather than administrative ones, though it's often the most genuinely useful document you can hand to another doctor.

El certificado médico oficial is a specific stamped form supplied through the colegios de médicos, used for things like licences, adoption processes, some sports registrations and certain official procedures. It normally requires an in-person examination, because the doctor is certifying a state of health, not describing a conversation.

When somebody searches for a baja médica online, they usually want the first of those terms and are about to be sold the second. Both are legitimate documents. Only one of them stops payroll from recording an unjustified absence — and which one your employer actually needs depends entirely on your company and your convenio colectivo.

Who can legally issue the official baja in Spain

This part is narrow, and it's narrow by design.

For an ordinary illness or a non-work accident — enfermedad común or accidente no laboral — the parte de baja is issued by a doctor of the public health service: in practice your médico de familia at your assigned centro de salud, or a doctor in the public urgencias network. Not a private clinic. Not a private online platform. Not a doctor based in another country. The authority to open a period of temporary incapacity for a common illness sits with the public system, because the state is the party paying and the party bearing the risk of misuse — a structure the INSS itself sets out in plain terms if you want to read the source rather than take our word for it.

For a work-related accident or occupational illness — accidente de trabajo or enfermedad profesional — the parte is issued by the mutua colaboradora con la Seguridad Social your employer contracts with for those risks, or by the public system where that coverage sits with the INSS. If you were hurt at work, the mutua is generally your first call rather than your centro de salud.

For self-employed workers, autónomos, the medical side works the same way through the public system, with an extra administrative layer: you also have to file a declaración de situación de la actividad with your mutua or the INSS within the required window, stating who is running the business while you're unable to. Plenty of autónomos discover this requirement weeks later and lose benefit days because of it.

Once a baja is open, the doctor sets a review pattern and issues partes de confirmación at intervals depending on the expected duration of your condition — more frequently for short episodes, less for long ones — until they issue the parte de alta.

One genuine improvement worth knowing about: Real Decreto 1060/2022, in force since 1 April 2023, removed the worker's old duty to hand a paper copy of the parte to the employer. The doctor now gives you a single copy for yourself; the health service or mutua transmits the data to the INSS electronically, and the INSS notifies the company through the Sistema RED within one working day. If your HR department is still asking you to physically bring in a copy, they're working from an outdated internal policy, and it's worth saying so politely.

One nuance the reform doesn't remove: you still need to tell your employer you're off sick — a call or message on the day — even though you no longer need to deliver any paperwork. The paperwork obligation disappeared; the courtesy of letting your boss know didn't.

So what can a private online doctor legitimately give you?

A great deal — as long as nobody pretends it's the INSS parte.

A licensed private doctor consulting by video can assess your condition, document it properly, and issue a private medical certificate or sick note stating that you were examined on a given date, that you present with a described condition, and that in their clinical opinion you're unfit to work for a stated period. Ours are produced as part of a normal consultation, described on our sick note and medical certificate page.

A private doctor can also issue a justificante confirming attendance, write a clinical informe you can hand to your médico de familia to avoid repeating the whole history, review and renew ongoing medication, and tell you clearly whether your situation needs to be escalated into the public system this morning rather than on Wednesday.

What determines whether the private document is enough is not medicine. It's employment practice. Many Spanish convenios colectivos and internal policies accept a justificante médico for short absences — the classic one, two or three days — precisely because generating a full IT process for a 36-hour stomach bug wastes everyone's time. Beyond that threshold, or where sick pay is involved, employers need the official baja because their obligations run through the social security system rather than through your goodwill. Some companies accept a private certificate readily; others accept nothing but the parte. The only reliable way to know is to read your convenio or ask HR directly — ideally before you actually need it.

Which document fits which situation

The examples below are illustrative composites rather than real patients.

Document	Who can issue it	What it's actually for	Available in an online consultation?
Parte de baja por incapacidad temporal (enfermedad común)	Public health service doctor — your médico de familia or public urgencias	Opening official sick leave and triggering statutory sick pay via the INSS	No. Only the public system can issue this
Parte de baja for accidente de trabajo / enfermedad profesional	The mutua colaboradora contracted by your employer, or the INSS	Work-related injury or illness, with its own benefit rules	No. Contact the mutua directly
Partes de confirmación and parte de alta	The same doctor or service that opened the baja	Extending or closing an existing period of incapacity	No
Private medical certificate / sick note	Any licensed doctor, including in a video consultation	Documenting a condition and recommended rest for an employer, school or university	Yes, where the consultation supports it clinically
Justificante de asistencia	Any clinician who saw you, public or private	Proving your absence had a medical reason, typically for short absences	Yes
Informe médico	Any licensed doctor	Passing clinical detail to another doctor, an insurer or a specialist	Yes
Certificado médico oficial (colegio form)	A doctor, on the official stamped form	Licences, official procedures, some sports and administrative processes	Generally no — usually requires physical examination
Certificado de aptitud laboral	Occupational health — the servicio de prevención de riesgos laborales	Confirming fitness for a specific job role	No — sits outside general medical practice

Take one honest look at that first row before you pay any website promising an instant baja. If a platform tells you it can issue the official Spanish IT parte after a five-minute chat, it's either describing a private certificate using the wrong word, or it's misleading you. Neither version is a good reason to hand over your data.

Two realistic cases

These are fictional examples, written to show how remote and in-person care differ.

Case one: the short absence. Nuria, 29, works at a Barcelona agency whose convenio accepts a justificante for absences of up to two days. She wakes with acute gastroenteritis on a Thursday. She books a video consultation for 09:15, speaks to a doctor for twelve minutes, receives advice on oral rehydration and the warning signs that would change the picture, and gets a private medical certificate recommending 48 hours of rest. She emails it to HR before ten. No baja is opened, because none is needed. By Monday she's back at work, and the whole episode never touched the social security system. This is the scenario where remote care genuinely solves the problem end to end.

Case two: the long absence. Andrés, 47, a bricklayer near Murcia, injures his shoulder lifting a load and can't raise his arm. His absence is going to run for weeks, his pay depends on it, and the injury happened at work. Here the correct route is his employer's mutua, immediately, with the accident reported properly. A private online consultation cannot open his baja, cannot manage the IT process, and cannot certify his fitness to return to a physically demanding role. What a remote consultation could reasonably do for someone in his position is answer evening questions about pain management or explain what the mutua process involves — useful, but peripheral. The core paperwork has exactly one legitimate door.

What your employer can and cannot ask for

Worth knowing, because a lot of stress in this area comes from people over-complying.

Your employer is entitled to know that you're absent and that the absence is medically justified. Your employer is not entitled to your diagnosis. A justificante or a private certificate does not need to state what's wrong with you, and a well-written one usually doesn't. Health data is a special category of personal data under the GDPR, and your medical history is not a workplace document. If a manager pushes for detail, "my doctor has certified that I'm unfit to work until Thursday" is a complete answer.

Employers may also arrange their own medical checks through occupational health services in defined circumstances, and mutuas and the INSS have their own review and inspection powers over open IT periods, including calling you in for assessment. That's normal and not an accusation. What is not normal is a company asking you to send your entire medical record to a general HR inbox.

On money: for ordinary illness, the first days of absence are typically unpaid unless your convenio improves on the statutory minimum, after which a percentage of your base reguladora applies and increases once the absence extends past the first few weeks. Work-related injury is treated more generously from the start. Your nómina and your convenio will tell you the specifics for your contract.

Warning signs of a service that will waste your money

The demand for quick sick notes has produced a crop of sites worth avoiding. Some patterns to treat as disqualifying:

A promise of an official Spanish baja or an INSS parte from a private platform. Not possible, full stop.
A guaranteed sick note before any clinical assessment. A certificate promised in advance of the consultation isn't a clinical judgement, and its value in a dispute is close to zero.
A form-only process with no doctor at any point. A document nobody clinically responsible signed is not a medical certificate.
No named, registered clinicians anywhere on the site. Registration with a professional body isn't optional in Spain, and legitimate services say who their doctors are — ours are listed on our doctors page.
A backdated certificate covering days before you were ever seen. Doctors can describe what you report about earlier days, but certifying a period they never assessed is a professional problem, not a customer-service feature.
No mention of data protection, retention or GDPR compliance. Our approach to how the service and its records are structured is described on our about page.

A useful test: does the service ever tell you when it can't help? A provider that has never turned a request down is optimising for conversion, not for medicine.

Honest limitations of a remote sick-note consultation

Beyond the legal boundary already covered, there are clinical limits worth stating plainly.

A doctor on a video call cannot examine you. For a stomach bug, a chest infection or a migraine that's usually acceptable, because the diagnosis rests on the history. For a possible fracture, a swollen joint, an abdomen that needs palpating, a back injury with neurological symptoms, or anything requiring a hands-on assessment of function, it isn't. Certifying fitness to work in a physical job after a musculoskeletal injury genuinely needs someone in the room.

Remote consultations can't order the analítica, radiology or specialist assessment that longer absences usually depend on. They can't prescribe controlled medicines, which rules out a category of pain and psychiatric treatment. They can't manage an open IT process, issue partes de confirmación, or sign your alta. And they can't make an employer accept a document that the employer's own policy doesn't recognise — the doctor's authority ends at the clinical judgement.

What remote care does well here is speed, documentation and direction: a same-day assessment, a properly written record, and a clear statement of whether you need to be in the public system this morning.

Red flags: when this isn't a paperwork question at all

Call 112 — the emergency number across Spain and the whole European Union — rather than booking any consultation, if you have:

Chest pain or tightness, particularly with sweating, nausea, breathlessness, or pain spreading to the arm or jaw
Sudden facial droop, one-sided weakness or numbness, or sudden difficulty speaking or seeing — possible stroke, where minutes change outcomes
Severe breathlessness, or an inability to finish a sentence
Persistent vomiting with no urine output, extreme drowsiness or confusion — signs of serious dehydration rather than a routine stomach bug
Severe abdominal pain with a rigid or tender abdomen
Bleeding that won't stop, a serious head injury, or loss of consciousness
A significant injury with visible deformity or inability to bear weight
Any thoughts of suicide or self-harm — call 112, or reach Spain's free, 24-hour 024 suicide prevention line directly. Neither of these needs to wait until you've finished reading a paperwork guide.

Travelling for work is common, so keep the equivalents in mind elsewhere: 112 works throughout the EU, and you can also use 999 in the United Kingdom, 15 (SAMU) in France, 118 in Italy, and 116117 in Germany for advice that's urgent but not an emergency.

Frequently asked questions

¿Se puede conseguir una baja médica online en España? You can obtain a private medical certificate or justificante online from a licensed doctor, and for short absences many employers accept it. You cannot obtain the official parte de baja por incapacidad temporal privately, because that's issued through the public health service by your assigned doctor, or by the mutua for work-related injury. Any site claiming otherwise is using the word incorrectly.

My employer wants "the baja" but I'll only be out two days. What should I do? Check your convenio colectivo first, because short absences are frequently covered by a justificante rather than a full IT process. If a justificante is sufficient, a same-day video consultation is often the fastest way to get one properly documented. If your company genuinely requires the official parte, you need your centro de salud — and it's reasonable to explain to them that the absence is already under way.

Does a private sick note from an online doctor have legal value in Spain? It's a genuine medical document signed by a registered doctor and carries the weight of that clinical opinion, which isn't nothing. What it doesn't carry is administrative effect within the social security system: it doesn't open a period of temporary incapacity and doesn't trigger statutory sick pay. Whether your employer accepts it is a matter of your contract and your convenio.

Can I get a baja médica online if I'm autónomo? The medical side still runs through the public system, so no. On top of the parte, self-employed workers must file a declaración de situación de la actividad with the mutua or the INSS within the required period, stating who is running the business during the absence. Missing that filing is one of the most common ways autónomos lose benefit they were otherwise entitled to.

Can an online doctor extend a baja my médico de familia already opened? No. Partes de confirmación and the eventual alta must come from the service that opened the process. A private consultation can, however, give you a documented clinical opinion to bring to that appointment, which sometimes helps if you feel a return-to-work date is being set too early.

Do I have to tell my employer my diagnosis? No. Your employer needs to know that you're absent and that the absence is medically justified. Your diagnosis is health data, protected as a special category under the GDPR, and neither a justificante nor a private certificate needs to disclose it.

Can a doctor issue a certificate for days that already passed? Only within limits. A doctor can record what you describe about the preceding days and can certify their assessment from the day they actually saw you. Certifying incapacity for a period they never assessed isn't something a responsible clinician does, and a document like that tends to collapse under any scrutiny.

What if my absence turns out to be longer than expected? Then the official route becomes unavoidable, and the sooner you start it the better. Get into the public system, open the baja properly, and let the review schedule run. Private care can sit alongside that — a second opinion, a faster look at something worrying, evening access when you have questions — but it can't replace the process. If a similar question comes up later, our FAQ page covers most of what people ask us, and the blog has more guides like this one.

The short version

If your absence is brief and your workplace accepts a justificante, a same-day online consultation with a licensed doctor is a reasonable and legitimate way to get the assessment and the document without losing a morning. If your absence will be longer, if sick pay matters, or if the injury happened at work, the official baja is the only thing that will do, and the route runs through your centro de salud or your mutua. Anyone selling you a shortcut around that is selling you a problem for later.

Because these rules are national, they differ once you cross a border — the equivalent processes under the French Assurance Maladie, the UK's NHS fit note, and Italy's SSN all work differently. If you need orientation in a market we don't cover clinically, Online Doctor Consultation keeps background health material, including European resource pages and Spanish-language content for readers who want it in another language. Neither replaces a consultation.
