Health Insurance in India: Sum Insured, Waiting Periods and Claim Rules

A health insurance policy is not a single number. Two policies with the same ₹10 lakh sum insured can behave very differently when you make a claim, because of waiting periods, room rent limits, co-pay, sub-limits and network restrictions.

This guide explains the features that matter, how to choose a sum insured, and the claim mistakes that lead to deductions. It is general information, not a substitute for reading your policy wording.

How much cover do you need?

Medical inflation in India has historically run higher than general inflation. A ₹5 lakh cover that felt adequate a decade ago may not cover a major surgery today. For a family in a metro city, a ₹10–₹25 lakh sum insured is a common range; a single person may need less, and a family with older parents may need more.

Employer group cover is useful but usually ends when you leave the job. A personal policy gives continuity and is worth having even if you have corporate cover.

Family floater vs individual policies

A common approach is a family floater for younger members plus a separate policy for parents. This avoids one large claim using up the entire family cover.

Waiting periods

• Initial waiting period: usually 30 days; emergency hospitalisation may be covered.
• Pre-existing disease waiting period: often 2–4 years; regulators have capped some periods, so check the current policy.
• Specific disease waiting period: common for conditions such as hernia, cataract or joint replacement.
• Maternity waiting period: often 2–4 years, and maternity cover may have sub-limits.
• Day-care procedures: many policies cover procedures that do not require a 24-hour stay.

If you have an existing condition, the waiting period is one of the most important features. A cheaper policy with a long waiting period may be worse than a slightly more expensive policy with a shorter one.

Room rent, co-pay and sub-limits

A room rent limit caps the room category you can use. If you choose a more expensive room, the insurer may reduce the payout proportionally, and associated charges such as surgeon fees and nursing may also be affected. Co-pay is a fixed percentage you pay on every claim. Sub-limits cap specific expenses such as cataract surgery or maternity.

Network hospitals and cashless claims

Cashless claims are settled directly between the insurer and a network hospital. Reimbursement claims require you to pay first and submit bills later. Check whether the hospitals near you are in the network and whether the policy allows cashless admission for planned procedures.

1. Inform the insurer or third-party administrator before a planned admission.
2. Carry your policy card and ID at admission.
3. Confirm the pre-authorisation approval and the approved amount.
4. Keep all bills, discharge summaries, prescriptions and investigation reports.
5. Review the final settlement statement for deductions.

Pre-existing conditions and disclosure

Insurers ask about your medical history at the proposal stage. Disclose diabetes, hypertension, thyroid conditions, past surgeries and smoking honestly. Non-disclosure can lead to a claim rejection or a policy cancellation, even years later.

If you have a pre-existing condition, compare policies on waiting period, loading and the definition of the condition. A policy that covers the condition after a shorter wait may be worth a higher premium.

Tax benefit under Section 80D

Under the old tax regime, health insurance premiums may qualify for a deduction under Section 80D. The limit is generally ₹25,000 for self, spouse and children, and ₹50,000 if the insured is a senior citizen. An additional deduction may be available for parents' premiums.

The new tax regime does not allow the 80D deduction. Do not buy health insurance only for the tax benefit; the main purpose is to protect your savings from a medical bill.

Common claim mistakes

• Not disclosing a pre-existing condition at purchase.
• Choosing a room above the policy limit.
• Delaying intimation to the insurer.
• Missing bills, prescriptions or investigation reports.
• Assuming the employer policy is enough after leaving the job.
• Not checking whether a procedure needs pre-authorisation.
• Letting the policy lapse and losing continuity benefits.
