How to Verify a Doctor's License in Latin America: Colombia, Mexico, Brazil and Beyond

Clinic websites, social media profiles and patient coordinators will all tell you a doctor is qualified. None of those are independent evidence. The only reliable starting point is the official register kept by the country's health authority or medical council. This guide walks through how verification works in several of the region's main medical travel destinations, what each check can and cannot tell you, and the warning signs that should end the conversation.

Registries change their web addresses and search screens from time to time. Where we describe a tool, search for it by its official name and make sure you are on a government or medical-council domain, not a look-alike site.

Two Separate Questions: License and Specialty

Every verification has two layers, and patients often stop after the first.

1. Is this person a licensed physician? This confirms they completed medical school and are authorized to practice medicine in that country.
2. Are they qualified in the specialty they are practicing? A licensed general physician is not automatically a plastic surgeon, orthopedic surgeon or anesthesiologist. Specialty training is a separate credential, recorded in different ways in different countries.

Many of the problems reported in medical tourism involve the second layer: a real doctor performing procedures outside their training. That is why a license check is necessary but not sufficient.

Colombia: ReTHUS

Colombia keeps a national registry of health workers called ReTHUS (Registro Único Nacional del Talento Humano en Salud). The Colombian Ministry of Health and Social Protection (2026) explains that registration confirms a worker meets the legal requirements to practice, and that the registry also records sanctions reported by ethics and disciplinary tribunals. A public “Consulta al ciudadano” tool lets anyone check a worker using an identification number.

How to use it

• Ask the doctor or clinic for the doctor's full name and Colombian identification number (cédula). A legitimate practice will provide it.
• Search the citizen consultation tool and confirm the name, profession and status match.
• Look for any recorded sanctions.
• Check whether postgraduate (specialist) training appears; if it does not, ask the doctor for proof of their specialty degree and the university that awarded it.

The ministry's page does not state that every specialty is shown, so treat a missing specialty entry as a reason to ask questions rather than as proof of anything on its own.

Mexico: The Professional License (Cédula Profesional)

In Mexico, professionals receive a cédula profesional recorded by the federal Secretaría de Educación Pública (SEP). Specialists typically also hold a cédula for their specialty, which is worth asking for alongside the general one. Patients can search SEP's public registry by name.

SEP has also introduced a digital document called the Constancia de Situación Profesional. According to ADN40 (2025), the tool lets people check the current status of a physician's cédula and also records items such as professional association membership and certificates, and was presented partly as a way to reduce fraud by people falsely claiming to be plastic surgeons.

How to use it

• Ask for the doctor's cédula number for medicine and, separately, for their specialty.
• Search SEP's registry and confirm both entries and the institutions that issued them.
• For surgical specialties, also ask which specialty board or council certifies the doctor and verify it on that body's own website.

Brazil: CRM Registration and the RQE

Brazilian doctors register with a regional medical council (CRM) in each state where they practice, under the oversight of the Federal Council of Medicine (CFM). In a 2026 guidance article, the CFM describes its free public “Busca por Médicos” tool, which lets anyone search by name or CRM number and state. The CFM says results include registration dates, registrations in other states, graduation institution and year, and registered specialties and areas of practice.

What to look for

• A status of active (“ATIVO”).
• A photo and details that match the person you are dealing with.
• For specialists, the RQE (Registro de Qualificação de Especialista). The CFM flags refusal to provide a CRM number, or an RQE when claiming a specialty, as a warning sign.

Costa Rica, Panama, Argentina and Others

Most countries in the region have a medical college, council or ministry that licenses physicians, and many offer some form of public lookup. In Costa Rica, for example, start with the national College of Physicians and Surgeons (Colegio de Médicos y Cirujanos). In federal countries such as Argentina, check whether licensing happens at national level, provincial level or both. The specific search tools, the information they show and how up to date they are vary, so:

• Identify the official licensing body for the country and, where relevant, the province or state.
• Check for a public search on that body's own site.
• If there is no public search, email the body directly with the doctor's name and license number and ask for confirmation.

A Comparison of What You Can Check

Beyond the Register: Five More Checks

1. Specialty society membership. National specialty societies, such as plastic surgery or orthopedic societies, often list members. Membership does not prove quality, but claimed membership that cannot be confirmed is a problem.
2. Hospital privileges. Ask which hospital the doctor operates in and call that hospital to confirm they have privileges there.
3. Who gives anesthesia. Ask whether a qualified anesthesiologist will be present, and verify that person's license too.
4. Facility licensing. The operating facility should be licensed by the health authority. For hospital accreditation, see the accreditation body's own list.
5. Consistency. Names, license numbers and photos should match across the register, the clinic website and your paperwork.

The CDC Yellow Book (2026) notes that the American College of Surgeons recommends using internationally accredited facilities and surgeons certified in their specialties, while also cautioning that accreditation does not guarantee a good outcome. Verification narrows your risk; it does not remove it.

What a License Check Cannot Tell You

Registries confirm status, not skill. A clean, active registration tells you nothing about how often a surgeon performs your particular procedure, what their complication rate is, or how they handle problems. Some registries also lag behind real events, so a recent disciplinary matter may not appear yet.

To fill those gaps, ask direct questions and judge the answers:

• How many of this exact procedure do you perform in a typical month?
• What are the most common complications you see, and how do you manage them?
• If I need a second operation to fix a problem, who pays for it?
• Will you personally perform the whole operation, or will another doctor do part of it?

A confident, specific answer is a good sign. Vague reassurance, or a claim that complications never happen, is not.

Send your questions in writing

Email the clinic your verification questions before any video consultation, and ask for the answers in writing. Written replies give you something to compare against the registry and something to refer back to if the plan changes. They also show whether the clinic is organized and transparent, which tells you a lot about what aftercare will be like.

Red Flags That Should Stop You

Keep a Record of What You Checked

Take a dated screenshot of each registry result and save it with your quotes and correspondence. If something goes wrong later, that record helps anyone trying to help you, from a doctor at home to a lawyer or complaint body in the destination country. It also protects you from a common problem: a coordinator who promises one surgeon and substitutes another.

Putting It Together

Verifying a doctor in Latin America is not complicated, but it does require doing it yourself rather than trusting what a clinic says. Confirm the license on the official register, confirm the specialty separately, confirm the hospital and the anesthesiologist, and save what you find. A good surgeon expects these questions and answers them without hesitation.

Frequently Asked Questions

Is a medical license the same as being board certified?

No. A license means the person may practice medicine. Specialist qualification and board certification are separate credentials, and you should verify them separately for any surgery.

What if the registry is only in Spanish or Portuguese?

Most registries are in the local language. A browser translation tool is usually enough to read the results, and you can ask the clinic to send the doctor's registration details so you can match them exactly.

The doctor is on the register but no specialty is shown. Is that a problem?

Not always, because some registries do not display every specialty. Ask for the specialty degree, the issuing university and any specialist registration number, then verify those with the relevant body.

Should I verify the anesthesiologist too?

Yes. Anesthesia carries its own risks, and the person providing it should be a licensed, trained anesthesiologist. Ask for their name and check them the same way.

Can a patient coordinator do the verification for me?

They can help gather details, but do the final check yourself on the official registry. Coordinators are often paid by clinics and are not independent.

Registry tools and web addresses change. This page explains the approach; always confirm on the licensing body's current official site.
