Diagnosis of illness often requires a person to undergo some tests or take some medicines. A person may also be required to take additional tests and medication after getting discharged. As long as all these expenses are linked to an event of hospitalization, the policy typically covers expenses for 30 days before hospitalization and 60 days post hospitalization unless specified otherwise in the terms and conditions of the policy. To avail these benefits, the patient needs to be hospitalized for at least 24 hours and the illness should be covered as per the policy's terms.
