Why is Health Insurance Mandatory in India in 2025?

• Steep rise in medical costs: The rising costs of advanced treatments (robotic surgery, organ transplants, immunotherapy), cutting-edge diagnostics and hospital infrastructure make even routine procedures expensive. Heart bypass can easily exceed Rs 4 lakh, and cancer treatment often runs into crores.
• Rising burden of lifestyle diseases: India is witnessing an alarming rise in diabetes, hypertension, cardiovascular diseases and cancer, which often require long-term and expensive management.
• Inadequate public healthcare: Despite improvements, public hospitals often suffer from overcrowding, lack of resources and limited access to the latest treatments, making quality private care essential for many.
• Financial protection: Health insurance serves as a crucial financial shield, preventing devastating out-of-pocket expenses that can derail financial goals and plunge families into debt.
• Beyond hospitalisation: Modern policies cover OPD expenses, wellness programmes, preventive health check-ups, teleconsultation and home treatment, providing holistic protection.
• A must-have for many: Employer-provided coverage may be inadequate, and freelancers/gig economy workers require individual policies. Senior citizens face higher premiums, but their need is even greater.

Key factors to evaluate for Best Health Insurance in India (2025)

Choosing is not just about the lowest premium. Consider these important aspects:

1. Adequate sum insured: This is paramount. Decide this based on:
   • City level (costs are significantly higher in metros).
   • Family size and age.
   • Existing health conditions.
   • Future inflation. Recommendation (2025): Minimum Rs 10 lakh for an individual living in a metro; Rs 15-20 lakh+ for families or those seeking comprehensive coverage. Consider top-up/super top-up plans for higher coverage affordably.

2. Plan type:
   • Individual plan: Covers one person.
   • Family floater plan: Most popular. Single sum insured covers all insured family members (spouse, children, dependent parents). Affordable, but shared coverage can be a drawback for large families or aged members.
   • Senior citizen plans: Specifically designed for those aged 60+, often with features like pre-existing illness coverage (after a waiting period), co-pays and OPD benefits. This is a must-have for the ageing population in 2025.
   • Critical illness plans: Pay a lumpsum on diagnosis of specific life-threatening illnesses (cancer, stroke, kidney failure). Complements your base policy.
   • Group health insurance (employer): Often the starting point, but usually insufficient. Portability options allow taking it when leaving a job.
   • Top-up/super top-up plans: Cost-effective way to boost coverage beyond the base policy's deductible (limit).

3. Network hospitals: The insurer's network of hospitals where cashless treatment is available is important. Key checks for 2025:
   • Size and reach: Does it cover quality hospitals near you? Leading insurers claim to have 10,000+ hospitals.
   • Quality: Are reputed chains (Apollo, Fortis, Max, Manipal, Medanta, etc.) included?
   • Ease of going cashless: Check reviews for ease of claim settlement within the network. Portals/apps are a must to locate network hospitals.

4. Claim Settlement Ratio (CSR): Percentage of claims settled by the insurer in a year. 2025 benchmark:
   • > 90%: Excellent.
   • 85-90%: Good.
   • < 85%: Needs careful scrutiny. Check IRDAI annual reports for latest data. Don’t rely on overall CSR alone; check CSR for specific plan type and your state, if possible.

5. Incurred Claim Ratio (ICR): (Total claims paid/Total premiums collected) x 100. Reflects the insurer’s profitability and pricing adequacy.
   • 50-100%: Generally considered healthy. Less than 50% may indicate overcharging; more than 100% may indicate underpricing, which could lead to future premium hikes or claim issues.

6. Waiting Period: Non-negotiable time period before coverage begins for specific conditions:
   • Initial Waiting Period: Usually 30 days (except for accidents).
   • Pre-Existing Diseases (PED): Usually 2-4 years. Trend for 2025: Some insurers offer shorter PED periods (1-2 years) at higher premiums. Check definitions.
   • Specific illnesses: Certain treatments (hernia, cataract, joint replacement) may have a waiting period of 1-2 years.

7. Sub-Limits & Co-payments:
   • Sub-Limits: Caps on specific expenses (room rent, ICU charges, surgeon fees). Avoid plans with room rent sub-limits, as they can drastically reduce overall coverage. Opt for plans without these or with very high limits.
   • Co-payment: A fixed percentage (e.g., 10-20%) of the claim amount you pay. Common in senior citizen plans or for treatment in non-metros. Understand when it applies.

8. Exclusions: Know what's NOT covered. Common exclusions include:
   • Cosmetic surgery
   • Dental treatment (unless due to accident)
   • Specific pre-existing conditions during waiting periods
   • War/terrorism related injuries
   • Treatment for substance abuse
   • HIV/AIDS (except specified plans)
   • Experimental treatments

9. Add-on Covers (Riders): Enhance your base policy for extra premium:
   • Critical Illness Rider: Lump sum payout.
   • OPD Cover: Consultations, diagnostics, pharmacy.
   • Maternity Cover: Prenatal, delivery, postnatal. Often has waiting periods (9 months to 3 years).
   • AYUSH Treatment: Coverage for Ayurveda, Yoga, Unani, Siddha, Homeopathy.
   • Restoration of Sum Insured: Reinstates the base sum insured if exhausted during the policy year.
   • International Treatment Cover: For treatment abroad.
   • Personal Accident Cover.

10. Premium Cost: Compare premiums for similar coverage across insurers. Factors influencing premium:
    • Age (biggest factor)
    • Sum Insured
    • Location (City Tier)
    • Medical History
    • Policy Term (Multi-year discounts)
    • Add-ons
    • No Claim Bonus (NCB)

11. Customer Service & Technology: Smooth claim settlement depends on efficient service. Check:
    • 24/7 Helpline availability.
    • Ease of use of website/app (policy management, claims tracking, network search).
    • Turnaround Time (TAT) for claim intimation and processing.
    • Online claim submission/document upload.

12. No Claim Bonus (NCB): Reward for claim-free years, usually increasing your Sum Insured by 5-10% per year (capped at 50-100%) or reducing the premium. A vital long-term benefit.

13. Policy Renewability: Ensure the policy offers lifetime renewability. This is crucial as health risks increase with age.
