Most private insurance as well as the “Beihilfe” cover the cost of psychotherapy in a private practice upon request.
Public insurance only cover it as “financial reimbursement”, for which certain requirements need to be met. I will gladly provide more information about this option.
You can also chose to pay privately.
The cost is in accordance with the “Gebührenordnung für Ärzte”, e.g. a 50-minute session of behavioral therapy is 100,55 Euro.
