When selecting a health insurance policy, experts emphasize that the base premium is not the only factor determining the value of the coverage. A policy may appear affordable initially but can leave the policyholder with significant out-of-pocket expenses if it contains restrictive clauses.

One primary feature to examine is the 'room-rent clause,' which dictates the maximum amount an insurer will pay for a hospital room. If a patient chooses a room exceeding this limit, they may be charged a proportionate increase in other medical costs. Additionally, the 'Pre-Existing Disease (PED) waiting period' is a critical factor; this is the duration a policyholder must wait before the insurer covers conditions they had prior to purchasing the policy.

Other features highlighted include the 'restoration benefit,' which automatically replenishes the sum insured if it is exhausted during the policy year, and 'co-pay' requirements, where the policyholder agrees to pay a percentage of each claim. Finally, 'disease-wise sub-limits' can restrict the amount an insurer pays for specific treatments, regardless of the total sum insured. Understanding these five areas is essential to ensuring that a health insurance plan provides meaningful financial protection during a medical emergency.
