The health insurance company covers the costs of medically necessary orthodontic corrections (KfO treatments) up to the age of 18. The decisive factor here is the start of treatment. The medical necessity of KfO treatment is assessed on the basis of five degrees of severity, the so-called orthodontic indication groups (KIG). From severity 3 (KIG 3), the health insurance pays the costs for children and adolescents under 18 years of age for the treatment. Adults usually have to pay for orthodontic treatment themselves. Exception: Medically justified cases, for example in severe jaw abnormalities, in which surgical corrections are also necessary.
Orthodontist's treatment plan
The severity of tooth misalignment is defined by five orthodontic indication groups. At least the classification in the treatment requirement level 3 of the indication groups is required.
