General insurance companies offer health policies which are mainly short term in nature. This means, that the health insurance policies can be renewed year after year and the premium amount varies with age.
Health insurance covers offered under general insurance, include mainly hospitalization covers either on reimbursement or cashless basis. The Third Party Administrators (TPAs) mainly offer cashless service as they have arrangements with various hospitals, who are the service providers. The TPAs also help in reimbursement claims.
