Health insurance policy holders will have to pay more in cities like Delhi and Mumbai, when compared to tier II and III cities, as per the zone-wise premium method adopted by health insurers.

Similarly, Future Generali’s Health Suraksha has basic, silver, gold and platinum plans. Zones are differentiated depending on the cost of treatment. This helps in charging premiums correctly as per risk and eliminates the high-cost areas.
However, experts debate that it would be difficult for policyholders, especially individuals, to make out the difference in premium as the insurers are experts in masking premium rates in such a way that the end user is not aware about it.
The age group of the insured, demographics, previous ailments and the likely number of claims the region would have in a given year are the factors that govern the premium rates. The differential premium policy is more evident in group policies as insurers resort to higher premium loadings for regions like Mumbai. Certain pockets within the country like Mumbai attract larger claims mainly on account of higher medical costs.
