Outpatient clinic De Blaak

What Outpatient clinic De Blaak does

Polikliniek de Blaak is a Netherlands-based multi-specialty outpatient clinic founded in 1990 (with the operating foundation Stichting Polikliniek De Blaak incorporated in 1991), operating across three physical locations in Rotterdam (Blaak 243/285 and Nieuwstraat 282), Rijswijk (Oranjelaan 1) and Tilburg (Ketelhavenstraat 39). It delivers care across six service lines: phlebology (varicose veins via duplex ultrasound, EVLT laser, sclerocompression therapy, Müller technique), proctology (haemorrhoids, fissures, abscesses, fistulas, skin tags), dermatology (eczema, psoriasis, acne, rosacea, skin cancer screening, STD testing), lipoedema (tumescent vibro-liposuction/PAL plus a dedicated knowledge centre and 'Dikke Benen Poli'), skin therapy (Harmony XL Pro laser, fractional CO2 laser, Dermapen, chemical peels, microdermabrasion, DAS Plasma), and cosmetic surgery (eyelid correction from €880, neck lift from €6,900, breast augmentation from €6,505, liposuction from €4,150, plus injectables). Care is delivered by vascular surgeons, dermatologists, phlebologists, proctologists, cosmetic surgeons and skin therapists, and is supported by an on-site recovery hotel (Herstelhotel) with 24/7 nursing care.

The business operates a dual-payor revenue model: insured medical treatments (phlebology, proctology, dermatology) require a GP referral and are billed directly to Dutch health insurers through the ZorgDomein referral platform, while cosmetic and uninsured treatments are paid out-of-pocket with instalment payment plans available. Pricing for uninsured treatments is publicly disclosed on the website, and skin-therapist consultations are free. Patients are acquired through a mix of GP referrals via ZorgDomein, direct self-referral via phone (085-488-1700) and the website/client portal, public information evenings on lipoedema and varicose veins, content marketing (blog, testimonials), and earned media (RTL4, SBS6, Teletrends, Altijd Jong; Libelle Zomerweek). The clinic reports a 9.0 patient satisfaction score on ZorgkaartNederland across 216 reviews, has held ZKN Keurmerk certification since 2007, and holds Spatader Keurmerk, Kwaliteitszegel Dermatologie, NVCG, KNMG, BIG-register, KP and Stylage accreditations. Since 2024 the entity has been owned by the Nederlandse Klinieken Groep (NLKG) and operates the Signé Clinics sub-brand for injectable treatments in Rotterdam.

Revenue model

1. Fee-for-Service Medical Treatments: The clinic operates a fee-for-service model where patients pay per consultation and treatment. Medical treatments covered by Dutch health insurance (e.g., varicose veins, dermatology, proctology) are partially or fully reimbursed when the patient has a referral letter from their GP and appropriate insurance coverage. Cosmetic treatments are paid out-of-pocket by patients. The clinic publishes passantentarieven (passer rates) for uninsured/self-paying patients.
2. Cosmetic / Uninsured Treatments: Self-pay revenue stream for cosmetic procedures (eyelid correction, breast augmentation, facelift, injectables, liposuction, etc.) that are not covered by health insurance. Patients pay directly for treatments. The clinic offers installment payment plans (betalen in termijnen).
3. Recovery Hotel (Herstelhotel): On-site recovery hotel offering overnight accommodation with nursing care for patients undergoing surgical procedures. Includes private double room, 24/7 nursing care, meals, and recovery support — an additional service revenue stream.
