Data Sources & Methodology
Every price on Wellness Vision names its source and the year its data describes. This page explains which sources we use, in what order, and how we label figures that no official source publishes. How each figure is checked: How we verify; what we have corrected: Corrections.
Editorial Independence
Wellness Vision receives no revenue from hospital referrals, procedure bookings or clinic sponsorships, and names no clinics. No source below has paid to be included.
How we choose a number
- Official price databases first. When a government or national health system publishes a price, we use it and cite the exact entry and its date.
- Then laws, health-policy research and peer-reviewed journals — always the specific document, never just an organisation's homepage, and checked against the document itself.
- Manufacturer announcements only for the manufacturer's own prices (for example a list-price cut or a self-pay price).
- Market estimates, labelled. Many treatments abroad have no official or peer-reviewed price. There we show ranges and call them market estimates — we do not present them as verified.
- Dated, converted the same way. Each figure carries the year its data describes. Foreign currencies are converted at the European Central Bank reference rate of the stated day.
We do not use clinic or hospital websites, medical-tourism agencies, data aggregators, Forbes Health, Healthline, WebMD or Wikipedia as a source of fact.
Official price databases and laws
The National Average Drug Acquisition Cost (NADAC) survey is our source for what US pharmacies pay for a drug, updated weekly. Medicare's negotiated prices come from CMS fact sheets; the Medicare GLP-1 Bridge from CMS program pages.
Official French list price, dispensing fee and reimbursement rate for each pack, with the date of the last update.
NHS indicative price for each pack and the date it took effect; NHSBSA pages for prescription-charge exemptions.
Statutory co-payment rules (§ 61 SGB V), including the increase from January 1, 2027 published in BGBl. 2026 I No. 228.
Research and peer-reviewed literature
US coverage, out-of-pocket and spending context. We cite the specific analysis and its data year, not the KFF homepage.
International drug price comparisons, for example US insulin prices against 33 OECD countries (2022 data: 9.71× gross, 2.33× net).
Graft counts and repair-case shares in hair restoration. The census publishes no prices, so we never attribute a price to it.
For example JAMA Network Open, BMJ Global Health, Obesity, Annals of Internal Medicine, Plastic and Reconstructive Surgery Global Open and Aesthetic Plastic Surgery — cited by author, journal and year, and checked against the paper itself, not a press summary.
AI Assistance Disclosure
Wellness Vision uses AI tools in production (Azure Neural TTS voice, DALL-E images, Grok Imagine visuals, Soundraw music) and AI assistance in research and drafting. Every figure is checked against the primary source it cites before publication, and those checks are recorded with a date.
Corrections
If you believe a figure on Wellness Vision is wrong, email info@wellnessvision.health with the relevant source. We review corrections within 7 business days. Every correction is listed with its date on Corrections; how we check figures is described on How we verify.
