Medical costs have been rising steadily, and a single hospitalisation can put real strain on a family’s finances. Health insurance is designed to help you prepare for such expenses, but a policy that looks cheap on premium can turn out to be restrictive when you actually need it. The price you pay matters far less than what the policy will and will not pay for.
This guide walks through the key things to check before buying a health insurance policy, with practical points for families in Kolkata. Suitability depends on individual circumstances, and policy benefits are governed by the terms, conditions and exclusions of the respective insurer.
Start with the sum insured
The sum insured is the maximum the insurer will pay in a policy year. A sum insured that is too small may be exhausted by a single serious hospitalisation. When choosing a figure, consider your family size, the ages of the members, and the cost of hospital care in your city. In a metro such as Kolkata, a higher sum insured is often worth considering.
Family-floater plans share one sum insured across all members, which can be cost-effective but means the cover is shared. Individual plans give each member a dedicated sum insured. Both structures have their place depending on your family’s needs.
Check waiting periods and exclusions
Most policies apply waiting periods before certain coverages begin. Understanding these before you buy prevents surprises later.
Pre-existing conditions
Pre-existing conditions such as diabetes, hypertension or thyroid disorders are usually covered only after a defined waiting period, which varies by insurer and plan. If you or a family member has a known condition, compare these waiting periods carefully before buying.
Specific treatments and exclusions
Some treatments, such as certain surgeries, maternity cover or dental procedures, may have separate waiting periods or be excluded entirely. Read the list of exclusions so you know what the policy will not pay for.
Room-rent limits and co-payment
Many policies cap the room rent you can claim — for example, a percentage of the sum insured per day. Choosing a room above this cap can lead to proportionate deductions on the entire claim, not just the room rent. Co-payment clauses require you to bear a percentage of the claim. Both of these affect how much you actually receive, so check them before you buy.
Cashless network hospitals
Cashless treatment means the insurer settles eligible bills directly with a network hospital. Before buying, confirm that the hospitals you are most likely to use in Kolkata are part of the insurer’s cashless network. A wide network makes a real difference at the time of an emergency.
Common mistakes to avoid
Buying the cheapest policy without reading exclusions and waiting periods.
Choosing a sum insured that is too low for your city and family size.
Not disclosing existing medical conditions accurately, which can affect claims later.
Ignoring room-rent limits and co-payment clauses that reduce the actual payout.
