A pre-existing condition is any health issue that was known, diagnosed, treated, or showing symptoms before an insurance policy begins. Insurers usually exclude these conditions to keep premiums affordable and prevent adverse selection. In Germany, public health insurance (GKV) covers pre-existing conditions, while private health insurance (PKV) and expat health insurance typically do not.
What counts as a pre-existing condition in insurance?
A pre-existing condition is a medical issue or health problem that existed before an insurance policy started. This includes any condition that was diagnosed, treated, or showing symptoms before the policy began, as well as a health issue you knew about beforehand and planned to have treated once the policy started. Common forms include:
Symptoms that were present but not yet diagnosed.
Illnesses or disorders that were already diagnosed.
Treatments previously received, such as medications, special diets, injections, or medical procedures.
Medical advice or routine check-ups sought before the policy began.
Why do insurers exclude pre-existing conditions from coverage?
Insurance works by pooling premiums from many people to cover the medical costs of those who need care. Covering pre-existing conditions without restrictions can unbalance that pool, because:
People may buy insurance only once they already need treatment for an existing condition.
This produces more claims than contributions in the pool.
The resulting imbalance would push premiums up significantly.
Excluding pre-existing conditions helps keep insurance affordable by managing risk and keeping the pool balanced.
What are some examples of pre-existing conditions?
Two examples show how a pre-existing condition can arise:
A chronic back problem treated with physical therapy for 2 years before a policy starts is a pre-existing condition.
Abdominal pain experienced for 6 months without seeing a doctor, but with the intention of getting treatment after buying insurance, is also a pre-existing condition.
Which health insurance in Germany covers pre-existing conditions?
In Germany, public health insurance (GKV) covers pre-existing conditions and provides comprehensive health coverage regardless of your medical history. Private health insurance (PKV) and expat health insurance typically do not cover pre-existing conditions, and may apply exclusions or surcharges based on your health at the time you apply. If you have a pre-existing condition and want full coverage for it, public health insurance is generally the option that includes it.
