You may want to enroll in a short-term health insurance after experiencing a job loss to get coverage while between jobs and employee benefits. You may also want a short-term plan if you are waiting for coverage to start and want protection in the meantime. Short-term plans usually have low premiums compared to other plans, and you can be approved quickly, sometimes on the spot. Short-term plans feature flexible terms and can cover you for any period between 30 days and 12 months. Short-term plans don’t cover pre-existing conditions and are not guaranteed-issue.
In social health insurance, contributions from workers, the self-employed, enterprises, and governments are pooled into a single or multiple funds on a compulsory basis. It is based on risk pooling.  The social health insurance model is also referred to as the 'Bismarck Model,' after Prussian Chancellor Otto von Bismarck, who introduced the first universal health care system in Germany in the 19th century.  The funds typically contract with a mix of public and private providers for the provision of a specified benefit package. Preventive and public health care may be provided by these funds or responsibility kept solely by the Ministry of Health. Within social health insurance, a number of functions may be executed by parastatal or non-governmental sickness funds or in a few cases, by private health insurance companies. Social health insurance is used in a number of Western European countries and increasingly in Eastern Europe as well as in Israel and Japan. 
Sub-limits: Keep an eye out for plans with sub-limits on room rent, surgeries, ICU charges, operating charges and other medical procedures. When you opt for a health insurance plan, you should be sure that the plan has no disease specific or expenditure specific sub-limit. In few cases, you may find such plans to be expensive but they will help you to evade greater financial risks as well as provide you with the freedom to opt for efficient medical treatment, that too at the best health care provider. A policy with no sub-limits will help you avoid unpleasant situations at the time of claims.
