Hospital accreditation gets all the attention in medical travel, but the person holding the scalpel is licensed and certified through an entirely separate system — one that varies enormously by country. Some nations run public registries where anyone can verify a doctor in two minutes. Others make verification genuinely difficult. Knowing which is which should influence where you go.
Here's how board certification and licensing actually work in the major medical destinations, and exactly where to check each one.
The Two Credentials That Matter Everywhere
Every country separates the same two questions, even when the institutions differ:
- Licensure — is this person legally permitted to practice medicine here? (Government or medical-council function.)
- Specialty certification — has this person completed accredited residency/fellowship training in the specialty they're advertising? (Boards, colleges, or registered-specialty systems.)
The classic medical tourism failure mode lives in the gap between them: a physician who is genuinely licensed — but as a general practitioner performing specialist surgery. Your verification must confirm both.
Country by Country: Where to Verify
| Country | Licensure check | Specialty check | Ease |
|---|---|---|---|
| United States | State medical board lookup (each state publishes one) | ABMS Certification Matters portal | Easy |
| Colombia | ReTHUS national registry — public, online, free | Registered specialty shown in the same ReTHUS record | Easy — among the most transparent in Latin America |
| Mexico | Cédula profesional lookup (federal registry) | Separate specialty cédula + specialty council (consejo) certification | Moderate — two documents to check |
| United Kingdom | GMC online register | GMC specialist register (same lookup) | Easy |
| India | National Medical Commission / state council registers | Degree & specialty listed in register entries | Moderate — data spread across state councils |
| Turkey | Ministry of Health / medical chamber records | Specialty boards; often verified via hospital credentialing | Harder — less public-facing; lean on hospital verification |
| Thailand | Thai Medical Council lookup | Specialty boards under the Council | Moderate |
The Colombia Case: ReTHUS in Practice
Colombia's ReTHUS (Registro Único Nacional del Talento Humano en Salud) is the anchor of the country's credential transparency. It is the single national registry of health professionals authorized to practice, searchable online at no cost. A ReTHUS record confirms the physician's identity, that their license is active, and their registered specialty — the exact two-question verification described above, in one lookup.
Ask any Colombian provider for the surgeon's full legal name as registered. Run the ReTHUS search yourself — never accept a screenshot. Confirm the registered specialty matches the procedure: a cosmetic surgery should show plastic surgery training, not general medicine. Any legitimate clinic will volunteer this information; treating the request as unusual is itself a signal.
What "Board Certified" Means — and Doesn't — Across Borders
In the US, "board certified" specifically means ABMS (or AOA) member-board certification after accredited residency. Abroad, the same phrase gets used loosely, so translate it into checkable claims:
- "Board certified in Colombia" should mean: a specialty registered in ReTHUS, earned through a university residency program. Checkable.
- "Board certified in Mexico" should mean: certification by the relevant specialty consejo plus a specialty cédula. Checkable — ask for both numbers.
- International society memberships (ISAPS, ISHRS, and similar) signal engagement with a specialty community and typically require credential review — a legitimate plus, but a supplement to national verification, not a substitute for it.
"Trained in the USA" (a weekend course in Miami and a US residency produce the same sentence). "Member of international societies" with no society named. "20 years of experience" with no verifiable specialty. And any resistance to providing the registered legal name needed for a registry check.
Volume: The Credential No Registry Shows
Once license and specialty check out, the strongest remaining predictor of your outcome is how often this surgeon performs your exact procedure — a number no public registry captures. Ask directly, in writing, and expect a number rather than an adjective. Our hospital research workflow covers how to frame those questions, and our quality metrics guide explains why volume dominates most other signals.
Want the verification done in the open?
Colombia Medical provides the ReTHUS registration details of every surgeon it refers — so you can run the check yourself before you commit to anything.
Ask About Verified SurgeonsFrequently Asked Questions
How do I verify a doctor in Colombia?
Search the ReTHUS national registry online — it's public and free. The record confirms the physician's active license and registered specialty in one lookup. Ask for the surgeon's full registered legal name and run the search yourself.
What does board certified mean outside the US?
The phrase is used loosely abroad, so translate it into checkable claims: a ReTHUS-registered specialty in Colombia, a specialty consejo certification plus specialty cédula in Mexico, GMC specialist registration in the UK. Verify in the national system, not the marketing.
What's the most common credential problem in medical tourism?
A genuinely licensed physician practicing outside their trained specialty — for example, a general practitioner performing cosmetic surgery. Always verify both the license and that the registered specialty matches the procedure.
Are international society memberships like ISAPS meaningful?
They're a legitimate supplementary signal — most require credential review — but they supplement rather than replace national license and specialty verification. Check the national registry first, then count memberships as a plus.
