Every year, thousands of Indian families buy health insurance without reading the fine print — and discover the gaps only during a claim. This guide walks you through the five things that actually matter when picking a policy.
1. Waiting periods — the clause most people miss
Every health policy has a waiting period for pre-existing conditions — typically 2 to 4 years. This means if you have diabetes or hypertension today, your insurer won't pay claims related to those conditions for the first 2–4 years of the policy. The key: buy young and healthy, before conditions develop. The waiting period clock starts the day you buy — not the day you need care.
There's also an initial waiting period of 30 days for most illnesses (accidents are usually covered from day one). And specific waiting periods of 1–2 years for things like hernia, cataract, knee replacement, and joint replacement — even if you don't have them yet.
2. Room rent limits — where most claims get partially rejected
Many policies cap the room you can stay in during hospitalisation — for example, "single AC room" or "1% of sum insured per day." If your policy caps room rent at ₹3,000/day and you stay in a ₹6,000 room, the insurer doesn't just deny the extra ₹3,000. They proportionately reduce every other expense — surgeon's fees, ICU charges, medicines — by the same ratio. This single clause can cut a claim reimbursement by 30–50%.
What to look for: Policies that say "no room rent sub-limit" or "any room." These cost slightly more but are far better value at claim time.
3. Network hospitals — cashless vs reimbursement
Cashless hospitalisation only works at network hospitals tied to your insurer's TPA (Third Party Administrator). Outside the network, you pay upfront and claim reimbursement — which takes 15–45 days and involves significant paperwork. Before buying, check whether your preferred hospital is in-network. This matters most for planned procedures.
4. Co-payment clauses
Some policies — especially those marketed to senior citizens — include a co-pay clause of 10–30%. This means you pay that percentage of every claim, regardless of the amount. A 20% co-pay on a ₹5 lakh claim means you pay ₹1 lakh out of pocket. Not ideal. Look for zero co-pay policies if you can find them at a reasonable premium.
5. What sum insured actually means in 2026
Medical inflation in India runs at 12–15% annually. A ₹5 lakh policy that felt adequate in 2020 now barely covers a single week of ICU care at a private hospital in a metro city. The minimum I recommend for a family of four in a metro: ₹25–50 lakh, ideally with a super top-up to extend coverage beyond the base limit. A super top-up is the most cost-efficient way to increase coverage without paying high premiums on the base policy.
The bottom line
Don't buy on premium alone. The cheapest policy is rarely the best one — it's usually cheapest because it has the most exclusions and sub-limits. Compare policies on: waiting periods, room rent limits, co-pay clauses, sub-limits on specific treatments, and network hospital strength in your city.
