What OCA does

OCA is a Dutch medical specialist rehabilitation (Medisch Specialistische Revalidatie, MSR) provider headquartered in Goes, Netherlands, founded in 1992 and operating 17+ clinics across the country. Its core offering is multidisciplinary MSR for chronic pain, musculoskeletal disorders, burnout, stress, depression, fibromyalgia, whiplash, and post-COVID symptoms, typically delivered through programs of approximately 12 weeks and combining rehabilitation physicians, physiotherapists, psychologists, and occupational therapists. A second core line, Werkhervatting en Re-integratie (work resumption and reintegration), is delivered to employees through employer-paid Bedrijfszorg contracts and UWV-funded cases.

OCA's commercial model relies on three revenue streams: (1) reimbursement under the Dutch basic health insurance package (basispakket) for MSR, with a €385 patient deductible and operation regardless of insurer contract status, (2) direct employer billing for work-resumption and occupational health services, and (3) insurance/UWV reimbursement for reintegration cases. Patient acquisition is B2B2C, driven by GP and medical-specialist referrals, employer occupational health programs, Zorgdomein referrals, and direct self-referral via oca.nl, supplemented by a HealthOffice digital patient portal.

In 2025 OCA merged with SRN (Samenwerkende Revalidatie Nederland) and Medinello to form TopzorgGroep Revalidatie, positioning the combined entity as the leading Dutch MSR provider. The company is private, has 251–500 employees, and reports having helped 10,000+ patients return to optimal functioning. Its differentiation rests on clinical specialization in pain rehabilitation, a national clinic footprint, and integration into Dutch insurer and employer referral networks.

Revenue model

1. Medical Specialist Rehabilitation: Medisch Specialistische Revalidatie (MSR) services are primarily reimbursed through the Dutch basic health insurance package (basispakket). Patients may have a deductible excess of €385 that applies. The organization can work with any health insurer regardless of contract status.
2. Work Resumption and Reintegration: When an employer registers an employee for work resumption and reintegration services, the invoice goes to the employer. In some cases, UWV (Dutch Employee Insurance Agency) may cover costs. The employer's company health service (bedrijfszorg) may also be involved.
3. Corporate Health Services: Bedrijfszorg (corporate health) services for occupational health and work resumption, billed directly to employers or insurance companies.
