Health Insurance Basics
Health insurance is one of the most important financial tools for protecting yourself and your family against unexpected medical expenses. With healthcare costs rising every year, a single hospitalization or surgery can place a significant financial burden on individuals and families.
Health insurance helps reduce these expenses by covering eligible medical costs according to the terms and conditions of the policy. Understanding how health insurance works is essential before purchasing a plan or making a claim.
What is Health Insurance?
Health insurance is a contract between an individual and an insurance company in which the insurer agrees to pay for eligible medical expenses in exchange for a premium.
A health insurance policy may cover:
- Hospitalization expenses
- Surgery costs
- Intensive Care Unit (ICU) charges
- Doctor consultation fees during hospitalization
- Diagnostic tests
- Medicines
- Ambulance services
- Day-care procedures
- Pre and post-hospitalization expenses (as specified in the policy)
The amount covered is called the Sum Insured.
For example: if you purchase a policy with a sum insured of ₹10 lakh, the insurer will pay eligible medical expenses up to ₹10 lakh during the policy period, subject to the policy’s terms and conditions.
Cashless vs Reimbursement Claims
There are two primary ways to receive health insurance benefits.
a)Cashless Claim
A cashless claim allows the insurance company to settle the hospital bill directly with the hospital.
How it works
- Visit a network hospital.
- Present your health insurance card.
- Complete the pre-authorization process.
- The hospital sends documents to the insurer or TPA.
- Once approved, the insurer pays the eligible expenses directly.
- You pay only non-covered expenses, if any.
Advantages
- Minimal out-of-pocket expenses
- Faster claim settlement
- Less paperwork after discharge
- Convenient during emergencies
Limitations
- Available only at network hospitals
- Subject to policy conditions and approval
b)Reimbursement Claim
If treatment is received at a non-network hospital, the patient initially pays the hospital bill.
The patient then submits all required documents to the insurance company for reimbursement.
Required documents
- Original hospital bills
- Discharge summary
- Investigation reports
- Pharmacy bills
- Doctor prescriptions
- Claim form
- Identity proof
- Cancelled cheque or bank details
After verification, eligible expenses are reimbursed according to the policy.
Waiting Period Explained
A waiting period is the time during which certain illnesses or treatments are not covered after purchasing a health insurance policy.
Different types of waiting periods include:
Initial Waiting Period
Most policies have a waiting period of around 30 days for illnesses, except accidents.
Specific Disease Waiting Period
Certain conditions may have waiting periods ranging from 1 to 4 years, depending on the insurer.
Examples include:
- Hernia
- Cataract
- Joint replacement
- Gallstones
- Varicose veins
Pre-existing Disease Waiting Period
Pre-existing diseases are generally covered only after completing the specified waiting period, often between 2 and 4 years, depending on the policy.
Pre-existing Disease (PED)
A pre-existing disease is any illness, injury, or medical condition that existed before purchasing a health insurance policy.
Examples include:
- Diabetes
- Hypertension
- Asthma
- Thyroid disorders
- Heart disease
- Chronic kidney disease
These conditions are usually covered only after the applicable waiting period has been completed.
Always disclose pre-existing conditions honestly. Non-disclosure can lead to claim rejection or policy cancellation.
Co-payment
A co-payment (or co-pay) is a fixed percentage of the claim amount that the insured person agrees to pay.
Example
Hospital bill: ₹5,00,000
Policy co-payment: 10%
Insurance company pays: ₹4,50,000
Policyholder pays: ₹50,000
Policies with co-payment often have lower premiums but require the insured to share part of the treatment cost.
Deductible
A deductible is the amount the policyholder must pay before the insurance company starts covering eligible expenses.
Example
Deductible: ₹50,000
Hospital bill: ₹3,00,000
You pay: ₹50,000
Insurance company pays: ₹2,50,000
Deductibles are common in top-up and super top-up health insurance plans.
Room Rent Limit
Many health insurance policies specify a maximum room rent that can be claimed.
Examples include:
- ₹3,000 per day
- ₹5,000 per day
- 1% of the sum insured per day
- Single private room entitlement
Choosing a room above the eligible limit may result in proportionate deductions, meaning you could have to pay part of other hospital charges as well.
Always check the room rent eligibility before admission.
Day-care Procedures
Advances in medical technology mean that many treatments no longer require a 24-hour hospital stay.
These are known as day-care procedures.
Common examples include:
- Cataract surgery
- Chemotherapy
- Dialysis
- Endoscopy
- Angiography
- Minor orthopedic procedures
- Lithotripsy
Most modern health insurance policies cover approved day-care procedures.
No Claim Bonus (NCB)
A No Claim Bonus rewards policyholders who do not make claims during a policy year.
Benefits may include:
- Increase in sum insured without additional premium
- Premium discounts (depending on the policy)
- Long-term savings
Example
Year 1
Sum insured: ₹5 lakh
No claim made.
Year 2
Sum insured increases to ₹5.5 lakh without extra premium (subject to policy terms).
Network Hospitals
Network hospitals are hospitals that have agreements with insurance companies or Third-Party Administrators (TPAs) to provide cashless treatment.
Advantages
- Cashless hospitalization
- Simplified documentation
- Faster claim approval
- Dedicated insurance help desk
- Reduced financial burden during emergencies
Before planned hospitalization, always verify whether the hospital is part of your insurer’s network.
