It pays for private treatment for any health conditions you develop after you take out the policy. This includes UK treatment you cannot get for free on the NHS.
Each insurer has different rules on what they can pay out for. This means you need to work out what symptoms and types of treatment you need to cover before you apply.
Comprehensive insurance usually includes cover for a much wider range of conditions and treatments than their other policies.
What does comprehensive health insurance cover?
Basic health insurance policies are usually cheaper but often only pay out for inpatient treatment, which is when you need to stay in a hospital bed for treatment or tests.
Comprehensive medical insurance policies usually cost more but cover you as an outpatient too.
This includes treatment, consultations with specialists and tests that do not need you to stay in hospital overnight.
They can also pay out for a wider range of sicknesses and injuries and offer cover for things like:
Treatment for cancer, e.g. chemotherapy
Access to a private room if you stay in a hospital
Optical and dental care
Alternative therapies, e.g. acupuncture
What is not included?
Each company's comprehensive policies have different rules on what private healthcare they pay out for and what is excluded.
Some comprehensive providers include cover for non-standard treatments, but others charge a higher premium if you add them as extras.
