In 2023, 70 percent of medical practices in a survey by the National Association of Statutory Health Insurance Physicians (KBV) reported patients who book appointments and do not come. KBV chief Andreas Gassen estimates that 10 to 20 percent of booked appointments are not kept. He has called for a fee, paid by the health insurers. In 2025 a spokesman for the pediatricians, Jakob Maske, demanded up to 100 euros per missed appointment. Es ist nicht mehr zu akzeptieren, dass Patienten Termine verbindlich vereinbaren und diese nicht wahrnehmen. It is no longer acceptable that patients make binding appointments and do not keep them.
