Reimbursement


All your consultations and treatments at NaderZorg fall under the regular insured care and are reimbursed by all health insurance companies, after referral from your general practitioner or other medical specialist. However, you should take into account the legal deductible. Because NaderZorg is a new care organization and has not yet been able to agree with health insurers on automatic settlement of your care costs, NaderZorg will send the bill to you, which you can then submit to your health insurer. Some health insurance companies do not pay the bill in full, depending on the insurance policy you have taken out. If your health insurance company does not reimburse the full amount, you do not have to pay the difference! So, you will have no additional costs at the NaderZorg for consultations or treatments. It is also possible to make an appointment with NaderZorg without a referral letter. Please contact us if this applies to you.

For international insurance companies, we will send the bill directly to you. Please settle your invoice with us upon receipt. Once you have paid, you can submit the invoice to your insurance company for reimbursement.

Frequently Asked Questions


1. What is internist? What is internal medicine?
Internist is a medical specialist of the internal organs. The specialty of Internal Medicine is a contemplative and incredibly broad profession. Internal medicine focuses on the prevention, examination and treatment of disorders of the internal organs. Internists deal with a range of disease states and a diverse patient population, adults of all ages - both acute and chronic. These include kidney disease, problems of the stomach, intestine or liver, vascular disease, joint disease and infectious disease. You will also be referred to internist for abnormalities in hormones, metabolism or for abnormalities in an examination. In hospitals, for cancer treatment (chemotherapy), you will see the internist.
Internist is a medical specialist who can provide the right care in the right place for patients with complex (and often multiple) conditions. In addition, internists possess knowledge of, for example, disorders of the heart, lungs and intestines, so that referral to other specialties need only take place when really necessary. Internists play a central role in the collaboration with other specialties, as the director of complex patients and as an interlocutor for other medical professionals. As such, the internist is a crucial link in care and also acts as a bridge between the first and second line.
