For psychotherapy, the costs are based upon the official fees for psychotherapists (Gebührenordnung für Psychotherapeuten, GOP) which you will find on the website of Psychotherapeutenkammer Bayern.
Public health insurance: unfortunately I will not be able to charge the public health insurers.
Private health insurance: usually the first five “trial“ sessions are reimbursed. The further funding depends on your contract. Your private health insurer will give you more information.
Self-payment therapy: self payment is possible. You will not be dependent on any insurer and no other party will be informed about the therapy.
The costs for coaching cannot be reimbursed by any health insurance, some companies pay for a certain amount of coaching sessions, however. You human ressources department will give you more information. The exact costs depend on your professional situation and range between 130 and 190 Euro for a 60 minutes session; 19% German VAT have to be added.
