• 85% of rejections are avoidable with proper disclosure and policy understanding

Top 10 Claim Rejection Reasons (Detailed)

1. Non-Disclosure of Pre-Existing Diseases (PED)

This is the single biggest reason for claim rejection (dabi). If you had diabetes, hypertension, thyroid, or any other condition before buying the policy and didn't declare it, the insurer can reject your claim — even for an unrelated illness.

How it happens: You buy a policy and don't mention your diabetes. Two years later, you're hospitalized for a heart attack. The insurer investigates your medical records, finds the undisclosed diabetes, and rejects the claim — even though heart attack and diabetes are different conditions.

Real example: A 45-year-old from Jaipur had his ₹8 lakh claim rejected because he didn't disclose a thyroid condition diagnosed 3 years before buying the policy. The insurer argued that thyroid contributed to his cardiac condition.

How to avoid:

• Declare ALL medical conditions, no matter how minor
• Include past surgeries, hospitalizations, and ongoing medications
• If in doubt, disclose it — it's better to pay a slightly higher premium than lose your entire claim
• Submit medical reports if requested during underwriting

2. Waiting Period Not Completed

Every health insurance policy has waiting periods (pratiksha avadhi):

How to avoid:

• Don't file claims during the waiting period unless it's an accident/emergency
• Buy insurance early — the waiting period countdown starts from day one
• Check your policy schedule for specific treatment waiting periods

3. Policy Lapsed or Expired

If you haven't paid your renewal premium, your policy is inactive. Any claim during the lapsed period will be rejected outright.

Real example: A family in Pune had their ₹5 lakh claim rejected because their policy had lapsed 12 days before the hospitalization. They missed the renewal date and hadn't opted for auto-renewal.

How to avoid:

• Set reminders for renewal dates (at least 30 days in advance)
• Opt for auto-debit/ECS for premium payment
• IRDAI allows a 30-day grace period — use it, but don't rely on it
• Buy multi-year policies (2-3 years) to avoid annual renewal hassle

4. Treatment Not Covered Under Policy

Every policy has an exclusion list (exclusion suchi). Common exclusions include:

• Cosmetic/plastic surgery (unless due to accident)
• Dental treatment (unless requiring hospitalization from accident)
• Vision correction (LASIK, spectacles)
• Infertility treatment / IVF
• Self-inflicted injuries
• Experimental or unproven treatments
• Obesity surgery (unless medically necessary and covered)
• War, nuclear risk, and adventure sports injuries

How to avoid:

• Read the policy document — especially the "Exclusions" section
• Ask your insurer before undergoing any planned procedure
• Get a pre-authorization for planned treatments

5. Room Rent Limit Exceeded

This is the most unexpected reason for claim rejection. If your plan caps room rent at 1% of sum insured (e.g., ₹5,000/day for ₹5L SI) and you choose a room costing ₹10,000/day, the insurer applies a proportional deduction on the ENTIRE bill — not just the room charges.

Real example: A patient in Delhi chose a ₹12,000/day room against a ₹5,000/day limit. The total bill was ₹3,00,000. The insurer applied a proportional deduction (5,000/12,000 = 41.6%) and paid only ₹1,25,000 — a loss of ₹1,75,000!

How to avoid:

• Choose a plan with no room rent limit or a high limit
• Always select a room within your plan's limit
• Add the Room Rent Waiver add-on if available

6. Delayed Intimation

Most policies require you to inform the insurer within:

• 24-48 hours for emergency hospitalization
• 3-5 days before planned hospitalization
• 7-15 days after discharge for reimbursement claims

How to avoid:

• Save your insurer's helpline number on your phone
• Intimate the insurer BEFORE planned admissions
• For emergencies, call within 24 hours — even from the hospital bed
• Use the insurer's app or website for quick intimation

7. Incorrect Information in Proposal Form

Providing wrong age, income, occupation, or medical details at the time of buying the policy can lead to claim rejection. This includes:

• Wrong date of birth
• Incorrect occupation (e.g., saying "office work" when you do hazardous labor)
• Not mentioning tobacco/alcohol use
• Hiding previous insurance claims

How to avoid:

• Fill the proposal form yourself — don't let agents fill it without your review
• Double-check every detail before signing
• Keep a copy of the proposal form for your records

8. Experimental or Investigational Treatment

Treatments that are not widely accepted in the Indian medical community or are still in clinical trial phase are typically excluded. This includes:

• Stem cell therapy (in many cases)
• Gene therapy
• Unproven cancer treatments
• Off-label drug use

How to avoid:

• Check with your insurer before undergoing any new/advanced treatment
• Get pre-authorization for expensive procedures
• Ask your doctor if the treatment is "standard of care" or "experimental"

9. Sum Insured Exhausted

In a family floater, if one member uses the entire sum insured, other members have no coverage left for that year. Also, if your medical bills exceed your individual sum insured, the excess is your responsibility.

How to avoid:

• Buy adequate sum insured (minimum ₹10L individual, ₹15-25L family)
• Add a super top-up for additional coverage at minimal cost
• Choose plans with restoration benefit

10. Drink-and-Drive, Self-Inflicted Injury, or Illegal Activities

Claims arising from illegal activities are automatically rejected:

• Accidents while driving under the influence of alcohol/drugs
• Self-inflicted injuries or suicide attempts
• Injuries from illegal activities or criminal acts
• Participation in riots or civil commotion

How to avoid:

• Never drink and drive — it's not just illegal, it also voids your insurance
• Seek mental health support — most policies now cover mental health treatment

What to Do If Your Claim Is Rejected

Step 1: Understand the Rejection Reason

Ask the insurer for a written rejection letter explaining the specific clause under which the claim was denied. You have the right to this information.

Step 2: Approach the Insurer's Grievance Redressal Officer (GRO)

Every insurer has a designated GRO. File a formal complaint with:

• Your policy number
• Claim reference number
• Rejection letter
• Supporting documents (medical reports, prescriptions)

Timeline: GRO must respond within 15 days.

Step 3: File a Complaint on Bima Bharosa Portal

If the GRO doesn't resolve your complaint, file it on IRDAI's Bima Bharosa portal (earlier known as IGMS):

• Website: bimabharosa.irdai.gov.in
• You'll get a complaint reference number
• IRDAI tracks all complaints and monitors resolution

Timeline: The insurer must respond within 15 days of Bima Bharosa intimation.

Step 4: Approach the Insurance Ombudsman

If still unresolved, approach the Insurance Ombudsman — a government-appointed independent grievance redressal authority:

• 17 Ombudsman offices across India
• Can award up to ₹30 lakh compensation
• No lawyer required — simple application process
• Free of cost

Eligibility: You can approach the Ombudsman only if:

• The claim value is up to ₹30 lakh
• You've first approached the insurer's GRO
• The complaint is not sub-judice (not in court)

Step 5: Consumer Forum / Court

As a last resort, you can file a case in the Consumer Disputes Redressal Commission:

Frequently Asked Questions

1. Can an insurer reject a claim after 2 years of continuous renewal?

After 2 years of continuous coverage, the insurer cannot reject a claim based on non-disclosure unless it's proven to be deliberate fraud. This is as per IRDAI guidelines — the 2-year moratorium protects policyholders from innocent non-disclosure.

2. How long does the insurer have to settle or reject a claim?

IRDAI mandates that insurers must settle or reject a claim within 30 days of receiving all required documents. For investigations, this extends to 45-90 days with written justification.

3. Can I re-file a rejected claim?

Yes, you can re-file a claim with additional supporting documents if the rejection was due to insufficient documentation. However, if the rejection is due to policy exclusions or non-disclosure, re-filing won't help — you need to go through the grievance process.

4. What is the success rate of the Insurance Ombudsman?

Approximately 60-70% of complaints filed with the Ombudsman are resolved in favor of the policyholder. The Ombudsman is generally consumer-friendly and follows principles of natural justice.

5. Does claim rejection affect my future premiums?

Yes, a rejected claim is still recorded in your insurance history. While it may not directly increase premiums, insurers may scrutinize future claims more carefully. However, a rejected claim does not affect your NCB in health insurance.

6. Can my health insurance be cancelled after a claim?

No, an insurer cannot cancel your policy mid-term simply because you filed a claim. They can only reject the specific claim if it falls under exclusions. They may choose not to renew at the next renewal, but must give you notice.

7. What is Bima Bharosa and how does it help?

Bima Bharosa is IRDAI's integrated grievance management system. When you file a complaint, it's tracked with a unique reference number and the insurer is mandated to respond within 15 days. It creates accountability and most insurers take Bima Bharosa complaints more seriously.

8. Is there a time limit for filing a complaint with the Ombudsman?

Yes, you must file a complaint with the Ombudsman within 1 year of the insurer's final rejection. If you approach after 1 year, the Ombudsman may not entertain the complaint unless there's a valid reason for the delay.
