Your hospital bill came to Rs 3.5 lakh, and you had a sum assured of Rs five lakh. Yet, you receive a claim of only Rs 3 lakh. One reason for that could be the room rent limit in your policy. Room rent limit in health insurance refers to the maximum amount an insurer will pay for hospital room charges on a per-day basis. Room rent limit charges, along with the pro-proportionate deduction clause, lead to a marked impact on the overall payout from the insurer. And it can lead to substantial out-of-pocket expenses even though you have an adequate sum assured.
