What does a Health Insurance policy not cover?

You must read the prospectus/ policy and understand what is not covered under it. Generally, pre-existing diseases (read the policy to understand what a pre-existing disease is defined as) are excluded under a Health Insurance policy. Further, the policy would generally exclude certain diseases from the first year of coverage and also impose a waiting period. There would also be certain standard exclusions such as cost of spectacles, contact lenses and hearing aids not being covered, dental treatment/surgery ( unless requiring hospitalization) not being covered, convalescence, general debility, congenital external defects, venereal disease, intentional self-injury, use of intoxicating drugs/alcohol, AIDS, expenses for diagnosis, x-ray or laboratory tests not consistent with the disease requiring hospitalization, treatment relating to pregnancy or child birth including cesarean section, Naturopathy treatment.
