Waiting periodTime after buying before some claims are paid — usually 30 days for illnesses (accidents are covered from day one).
Buy early so it's over before you need it.
Pre-existing disease (PED)Conditions you had before buying, like diabetes or BP. Covered after a waiting period — now at most 3 years.
Always declare them honestly.
MoratoriumAfter 5 continuous years (60 months) of cover, the insurer can't reject a claim for non-disclosure, except in proven fraud.
Never let a policy lapse — renew on time.
Room-rent limitA cap on the room you can choose. Pick a costlier room and other bills may be cut in the same proportion.
Prefer "no room-rent limit" plans.
Co-paymentA fixed share of every claim you pay yourself, e.g. 20%. Common in senior citizen plans.
Lower premium, but higher cost at claim time.
Sub-limitsCaps on specific treatments like cataract or knee replacement, regardless of your sum insured.
Check the list before buying.
No-claim bonusYour sum insured increases for every claim-free year, at no extra premium.
Higher bonus % is better.
Restoration / rechargeIf your cover is used up during the year, it's refilled for another claim.
Valuable for family floaters.
Cashless vs reimbursementCashless: insurer pays the network hospital directly. Reimbursement: you pay first, then claim with bills.
Check that hospitals near you are in-network.
