If you are insured with a statutory health insurance scheme, the health insurance fund will cover the entire costs of psychotherapy where medically necessary. Costs are settled directly with the health insurance fund.
If you have private health insurance or receive financial assistance, a private invoice will be issued in accordance with the schedule of psychotherapists' fees (Gebührenordnung für Psychotherapeuten – GOP). You can present the invoice to your insurance company or financial assistance office and they will generally reimburse the costs. Please check that your policy covers this beforehand.
In certain circumstances it may make sense to bear the costs of the therapy yourself. This is usually the case when a psychological condition can be excluded (e.g. where you wish to increase your self-awareness).
