BUZZ Ltd. provides participating doctors and pharmacies with an internet platform through which patients can receive online medical treatment or other services from doctors and buy medicines from pharmacies. The platform is used in particular by pharmacies and doctors to connect with patients to order medicines or medical services online, especially for online treatment for the purpose of preparing prescriptions and sickness certificates. Doctors who are authorised to issue a certificate of incapacity for work WITHOUT medical consultation operate internationally and offer their services exclusively online. As a result, there is no need for these doctors to have a physical office or licence in the patient’s country. This can cause confusion for employers, especially as the chosen virtual address of the doctor indicated on the certificate of incapacity for work is not registered with the country’s competent medical association. Therefore, if the employer does not immediately accept the written certificate of incapacity for work, choose the certificate of incapacity for work with a medical consultation from German-licensed doctors or go to the doctor’s office.
