All health insurers have included reimbursement for UVB (home) treatment in the basic package. The costs are covered by the mandatory deductible.

Medizorg, or another supplier of UVB light equipment, must make agreements with the hospitals about reimbursement. This has now been arranged for most major hospitals. It is a bit more difficult for small hospitals and independent treatment centers. Patients treated there are advised to check with the dermatologist whether there are agreements with, among others, Medizorg and the health insurer about reimbursement. If that is not the case, it must be arranged first.
It is unknown whether additional insurance would be useful to reduce the personal contribution for this treatment. Patients will have to check this with their own health insurer.
