Buying a health insurance policy is one of the most important financial decisions you will make. With medical inflation rising at 12–14% annually, even a short hospitalisation can exhaust savings. Yet, most claim disputes and rejections happen because policyholders buy plans without understanding key terms.

To protect yourself and your family, here is a complete, practical checklist you MUST go through before buying any health insurance plan — whether it’s for individuals, families, parents, or senior citizens.
1. Check the Sum Insured (Coverage Amount)
Your sum insured must match today’s medical costs.
- For metros: At least ₹10–25 lakh
- For families: Consider a family floater with ₹20–30 lakh
- For parents/seniors: Minimum ₹10–15 lakh + Super Top-Up
Tip: Always combine a base policy with a super top-up for higher coverage at a lower premium.
2. Understand Waiting Periods
Waiting periods cause a large share of claim rejections.
Check for:
- Initial waiting period: 30 days
- Pre-existing diseases (PED): 2–3 years
- Specific conditions: Hernia, joint replacement, cataract, etc.
Choose insurers offering reduced PED waiting period options (with extra premium).
3. Look for Room Rent Limits & Room Category
This is a major hidden cost. If your policy has a cap like 1% of SI for room rent, you may end up paying proportionately for everything — doctor fees, diagnostics, nursing charges.
Best: Choose “No Room Rent Capping” or “Any Room Category (except suite)”.
4. Review Sub-Limits
Many policies silently add caps on:
- Cataract surgery
- Modern treatments like robotics
- AYUSH
- Ambulance
- Daily cash
- Maternity
Go for plans with minimal or zero sub-limits, unless you are aware and comfortable.
5. Co-payment Clause
A co-pay means you pay a percentage of every claim.
Example: 20% co-pay → You pay ₹20,000 on a ₹1,00,000 bill.Avoid co-pay clauses unless buying for senior citizens or high-risk age bands.
6. Check the Network Hospital List
Before buying:
- Verify your preferred hospitals are in-network
- Check if cashless is available
- Ensure the insurer has a strong presence in your city/locality
7. Pre & Post Hospitalisation Coverage
Look for:
- At least 60–90 days pre-hospitalisation
- At least 90–180 days post-hospitalisation
This matters for conditions requiring long follow-ups like cancer, cardiac issues, or surgeries.
8. Day-Care Procedures Coverage
Ensure the policy covers all modern day-care procedures without listing limitations.
9. Restoration Benefit (Refill Benefit)
This automatically restores your sum insured if it gets exhausted.
Choose:
- Unlimited restoration
- Applicable for same illness (most insurers restrict this)
10. OPD & Preventive Care Benefits
Good to have:
- OPD doctor consults
- Diagnostics
- Dental
- Annual health check-ups
As preventive care becomes important, these benefits add real value.
11. Claim Settlement Ratio & Customer Service Experience
High claim settlement ratio is not enough — look for:
- Speed of settlement
- Transparency
- Reviews
- Ease of documentation
- Support during hospitalisation
Pick insurers known for quick and fair claims.
12. Understand Exclusions
Common exclusions include:
- Cosmetic surgery
- Non-allopathic treatments beyond limits
- Unproven therapies
- War/riot-related injuries
- Unregistered hospitals
Always read the policy wording before paying.
Bonus Tip: Use a 30-Day Free-Look Period Wisely
Most consumers don’t know this — you get up to 30 days as a free-look period If you find the policy unsuitable, you can cancel and get a refund.
Final Thoughts
