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 by name or number; specialty matches what is advertised; status current. Found in the Ärzteliste at the practice address with the specialist qualification that covers aesthetic surgery; the further-qualification block carries the same specialty and no other. [board] Ordination: Plastische, Rekonstruktive u. Ästhetische Chirurgie |
OFF | 26 | 2026-09-20 | |
| M2 | Identifiability of the responsible physician Physician(s) named with role and tied to this address. The physician is named with his role and tied to this address on the practice site. [site] |
SEC | 16 | 2026-09-20 | |
| M3 | Basic medical licence Matched by name. Matched by name in the Ärzteliste; the public view of the register publishes no licence number. [board] |
OFF | 8 | 2026-09-20 | |
| M4 | Facility registration Could not verify — no points, counts against coverage, not a negative finding. Reason: Queried, no match. Last attempt: facility_registry, 20 September 2026 — 0 rows in either list: no selbstständiges Ambulatorium and no Krankenanstalt is registered at Tulpengasse 2/2, 1080 Wien or under this practice name. A one-physician Ordination is not a Krankenanstalt under Austrian law, so no entry is expected. |
? | ? | 10 | 2026-09-20 |
| M5 | Legal-entity traceability Brand only. The § 5 ECG Impressum names Priv.-Doz. Dr. Stefan Hacker personally; no company, legal form or Firmenbuch number is given, so the practice publishes no legal entity. [site-impressum] |
SEC | 8 | 2026-09-20 | |
| M6 | Self-disclosure of identifiers No identifiers at all. The Impressum lists the physician's name, specialty title, addresses and contact details; no UID, Firmenbuch number or physician licence number is published. [site-impressum] |
SEC | 10 | 2026-09-20 | |
| M7 | Advertising honesty No pattern from the lexicon found. Lexicon scan of the home page, the services page, the contact page and the Impressum in German: no guarantee, no absolute-safety claim and no superlative about the practice itself. [site] |
SEC | 12 | 2026-09-20 | |
| M8 | Cross-locale consistency Could not verify — no points, counts against coverage, not a negative finding. Reason: Single language front. Last attempt: clinic_site, 20 September 2026 — one language front; no hreflang alternates or language links The clinic site publishes one language front; nothing to compare. |
? | ? | 5 | 2026-09-20 |
| M9 | Patient documents None. Pages loaded in German on 2026-09-20: home, services, contact, Impressum. None of the five classes is published; the only dispute wording is the standard statement in the Impressum that the practice does not take part in consumer dispute resolution. [site] |

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.

|---|---|
| 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

What we could not verify
- M4 · Facility registration — Queried, no match
- 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.
