The mobile service app of the IKK Berlin and Brandenburg: Declaring sick leave quite comfortably and safely on the go. The transmission of your sick report to us has never been so easy: Registered users of our Internet office "My IKK BB" can now transmit your sick report in just a few steps to us. Of course, we protect your data with a two-factor authentication. After a single activation of your device for the authentication process, you can start and report sick leave via app: Login - take a photo - submit - done! For all other concerns you will find in the app the contact details of our offices as well as a contact form and our service number. Further services for our insured will follow shortly. We look forward to your feedback on the IKK BB app.
