Axis by axis
rubric value 1–5 · ? could not verify (no points, not a negative finding) · — not applicable: this country has no register of that class · OFF official register · SEC secondary source
| Axis | Finding (rubric anchor) | Value | Source class | Weight | Checked |
|---|---|---|---|---|---|
| M1 | Specialist certification of the responsible physician Found, status current; the registered specialty matches what this physician advertises. Both surgeons matched in the Ärztekammer Hamburg Arztsuche, branch 'Plastische und Ästhetische Chirurgie', at the practice address. [register-hh] |
OFF | 26 | 2026-08-31 | |
| M2 | Identifiability of the responsible physician Physician(s) named with role and tied to this address. |
SEC | 16 | 2026-08-31 | |
| M3 | Basic medical licence Could not verify — the clinic publishes nothing to query (no physician surname, or no legal entity), so the cell stays in the coverage calculation. Not a negative finding. Reason: Nothing to query. Last attempt: medical_licence, 20 September 2026 — No matching entry. 116117 lists physicians in statutory-insurance (Vertrags-) practice only, so a purely private aesthetic practice is legitimately absent — absence is never read as unlicensed. |
? | ? | 8 | 2026-09-20 |
| M4 | Facility registration Could not verify — by its own definition this register does not cover this class of facility or this territory, so the axis is left out of the coverage calculation for this record. Not a negative finding. Reason: Register does not cover this class of facility or this territory. Last attempt: none_found, 22 September 2026 — § A: the register of this class does not cover this unit by its own definition (scopeGap in the map); previous state null not_found. |
? | ? | 10 | 2026-09-20 |
| M5 | Legal-entity traceability The legal entity is named; the register of this class is not accessible or does not cover this legal form (sole practitioner, private practice). GmbH named; no Handelsregister number is published and the register itself is not machine-accessible. [impressum] |
SEC | 8 | 2026-08-31 | |
| M6 | Self-disclosure of identifiers Partial, without issuers. A physician's licence-issuing Land (Lower Saxony, 2004) is named; no company registration or VAT number is published. [impressum] |
SEC | 10 | 2026-08-31 | |
| M7 | Advertising honesty No pattern from the lexicon found. |
SEC | 12 | 2026-08-31 | |
| M8 | Cross-locale consistency Could not verify — no points, counts against coverage, not a negative finding. Reason: Single language front. Last attempt: clinic_site, 17 September 2026 — one language front; no hreflang alternates or language links The clinic site publishes one language front; nothing to compare. |

Score ceilings
No ceiling applies. We never apply one on 'not found' alone.
Holds
No hold on this profile.
Inclusion policy
Four mechanical conditions. The first three decide whether a clinic is listed at all; the fourth decides whether it can be scored.
| Identifiable: live public surface + working in-country contact | verified yes [site] |
|---|---|
| Provides the service itself (not an aggregator, booking site or tour packager) | verified yes [site] |
| In scope: the intervention is performed by a physician | verified yes [site] |
| Names a responsible physician | verified yes [site] |
Who is responsible
Named physicians and the legal entity, as published and as matched in the registers. A missing number is a statement about disclosure, not about licensing.

What we could not verify
- M3 · Basic medical licence — Nothing to query
- M4 · Facility registration — Register does not cover this class of facility or this territory
- M8 · Cross-locale consistency — Single language front
These cells score nothing and are not negative findings. A cell on a register that is closed to machine queries is left out of the coverage calculation; the others count against it. Each one names why it is empty; an attempt that did not complete is re-run in the next collection pass. If you can point to a public source, send it.
