KZT/LZT deadline calculator

KZT is Kurzzeittherapie (short-term therapy), LZT is Langzeittherapie (long-term therapy). How many sessions remain before KZT 2 can be requested, what is the latest point for requesting conversion to long-term therapy, and how many hours remain before the approval step and the maximum?

Scope: individual therapy for adults. Group therapy and combined treatment have different limits and are not calculated here. The calculator is for orientation and does not replace reading the guideline (Psychotherapie-Richtlinie, PT-RL) and the rules of your Association of Statutory Health Insurance Physicians (Kassenärztliche Vereinigung). Values as of 4 October 2026.
