Every country with a functioning health system has a public registry where you can verify that a doctor is who they say they are. In Colombia, that registry is called ReTHUS — the Registro Único Nacional del Talento Humano en Salud. It's maintained by the Ministry of Health, it's free, and it takes less time to check than it does to read a Yelp review.
This is the single most important step in planning a medical trip to Colombia. Not reading Instagram before-and-afters. Not counting follower counts. Not googling "best surgeon in Medellín." The ReTHUS check is binary: either your surgeon appears in the national registry with active credentials, or they don't. Everything else is marketing.
The ReTHUS Walkthrough
Here's how to check any Colombian health professional's credentials — surgeon, anesthesiologist, nurse, dentist — in under two minutes.
Go to the ReTHUS Portal
Navigate to the Ministry of Health's ReTHUS search page. The URL is rfrethus.minsalud.gov.co. The site is in Spanish, but the search function is straightforward — you only need the surgeon's name.
Tip: Use Chrome's built-in translate if you need it, but the search fields are self-explanatory.
Enter the Surgeon's Name
Type the surgeon's first name in "Primer Nombre" and their last name(s) in "Primer Apellido" and "Segundo Apellido." Colombian names typically have two last names — paternal first, maternal second. If you're unsure which is which, try the first surname in "Primer Apellido" and leave the second blank.
Tip: If you only have a single last name, put it in "Primer Apellido" and leave the rest blank.
Review the Results
The registry returns every health professional matching that name. Look for your surgeon's tipo de identificación (ID type), número de identificación (ID number), and most critically — their listed profesión (profession) and especialización (specialization). A plastic surgeon should show "Cirugía Plástica Estética y Reconstructiva" or similar. A general dentist shows "Odontología."
Tip: If you have the surgeon's cédula (ID number), you can search by number instead — it's faster and unambiguous.
Check the Status
The entry should show an active status — meaning the professional's registration is current. Look for "Activo" or "Vigente." If the registration shows expired, suspended, or cancelled, that's a hard stop. Do not proceed with that surgeon, regardless of what their website says.
Tip: Screenshot the result. You now have a government-verified record of your surgeon's credentials.
Verify the Specialization Matches
This is the step people skip, and it matters enormously. A registered physician who trained in general surgery is not a board-certified plastic surgeon. A general dentist is not an oral and maxillofacial surgeon. Confirm that the listed specialization matches the procedure you're traveling for. "Médico Cirujano" (general physician/surgeon) without a listed specialization in your procedure type is a red flag.
Beyond ReTHUS: The Full Verification Stack
ReTHUS confirms credentials. But credentials are the floor, not the ceiling. Here's the full stack of verification layers for a Colombian medical professional.
| Layer | What It Verifies | How to Check |
|---|---|---|
| ReTHUS Registry | Licensed, active, specialty registered with the Ministry of Health | rfrethus.minsalud.gov.co — free public search |
| Medical Society Membership | Active member of the relevant Colombian specialty society (e.g., SCCP for plastic surgery, SCO for ophthalmology) | Society websites typically have member directories |
| Hospital / Clinic Affiliation | Operating privileges at an accredited facility — not just a rented OR suite | Ask the clinic directly; cross-check with the hospital's staff directory |
| JCI Accreditation (Facility) | The hospital or clinic meets Joint Commission International standards for patient safety | jointcommissioninternational.org — public directory |
| International Board Certification | Additional training or fellowship in another country (US, Spain, Brazil common for Colombian surgeons) | Request documentation directly; verify through the issuing institution |
| Patient References | Real, contactable previous patients (not curated testimonials on a website) | Ask the clinic for references; independently verify through patient forums |
Red Flags vs. Green Flags
Red Flags
- Surgeon doesn't appear in ReTHUS at all
- Listed specialization doesn't match the procedure being offered
- Registration status shows expired or suspended
- Surgery performed in an unaffiliated private office instead of a hospital or accredited clinic
- Surgeon refuses to share their cédula number or university training details
- No before-and-after photos of their own patients — only stock imagery
- Pricing dramatically below the typical range (below-market pricing often means corner-cutting on anesthesia, facility, or post-op care)
- Pressure to book immediately or "lose a slot"
- Communication only through a middleman — never directly with the surgeon
Green Flags
- Appears in ReTHUS with matching specialization and active status
- Member of the relevant Colombian specialty society
- Operates at a named, accredited hospital or clinic
- Willing to do a video consultation before you commit
- Provides real before-and-after galleries with patient consent
- Clear pre-op requirements and medical questionnaire
- Transparent pricing breakdown (surgeon fee, anesthesia, facility, labs, follow-up)
- Offers contactable patient references
- Direct communication with the surgeon or their dedicated coordinator
How Confidence Stacks
No single check gives you certainty. But each layer adds meaningful signal. Here's how confidence levels stack as you move through the verification process.
Confidence Level by Verification Depth
Notice where Instagram falls on that meter. Social media presence is marketing. It tells you a surgeon has a marketing budget or a good photographer. It tells you nothing about credentials, complication rates, or what happens when something goes wrong at 2 AM.
What About "Medical Tourism Coordinators"?
Many patients first encounter Colombian surgeons through third-party coordinators — people or companies who connect international patients with local surgeons and handle logistics. These can range from highly professional facilitators to unlicensed middlemen with Instagram accounts.
A good coordinator is genuinely helpful — they handle translation, airport transfers, accommodation, and post-op check-ins. But the coordinator is not a replacement for your own due diligence. Even if your coordinator "already verified" the surgeon, do the ReTHUS check yourself. It takes two minutes, and it's the one step you should never outsource.
Ask your coordinator these questions directly:
- What is the surgeon's full name and cédula number?
- Which hospital or clinic will the procedure take place in? (Not just "a clinic in El Poblado")
- Is the coordinator licensed by any Colombian entity, or are they a private facilitator?
- What is the coordinator's relationship with the surgeon? (Referral fee? Employment? Independent?)
If any of these questions make the coordinator uncomfortable, that's information.
The Two-Minute Version
If you take nothing else from this article:
- Get the surgeon's full name (two last names) or cédula number
- Search them on rfrethus.minsalud.gov.co
- Confirm the specialization matches your procedure
- Confirm the registration is active
- Screenshot the result for your records
That's it. Two minutes, zero cost, one government-backed answer. Everything else you learn about the surgeon builds on this foundation — but nothing replaces it.
