Top Five Reasons Health Insurance Claims are Rejected

A medical emergency brings immense mental and physical stress. During such hard times, health insurance acts as a critical financial shield. You get admitted to a hospital with the hope that your insurance provider will take care of the bills.

However, when you are informed of claim rejection all of a sudden, it can completely shatter your peace of mind. In no time, you have to bear massive out-of-pocket expenses that can drain your hard-earned savings.

Key Takeaways

• Honesty pays: Always disclose your complete medical history, including lifestyle habits like smoking, when buying a policy.
• Track your dates: Claims made during active waiting periods for specific diseases will face straight rejection.
• Intimate on time: Timely notification to your insurer about hospitalization is mandatory.
• Perfect paperwork: Missing documents, illegible bills, or mismatched names are major hurdles.
• Be aware of your limits: Policy exclusions and room rent sub-limits can drastically impact your final payout.

Introduction

In India, health insurance awareness is growing rapidly. Yet, many policyholders face the bitter reality of rejected claims. In the last 6 years, health insurance complaints have doubled and this comes to 80% of all grievances.

It is also to be noted that close to 70% of complaints in the health and general insurance category were related to claim rejections, delays, partial payments or documentation disputes. People often blame the insurance company immediately when a claim fails.

However, the root cause usually lies in minor oversight, missed deadlines, or a lack of understanding of the policy terms. Knowing the exact health insurance claim rejection reasons can save you from financial distress when you need help the most.

The Top 5 Reasons

Let us break down the top five reasons why health insurance claims get rejected in India and see how you can avoid these pitfalls.

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

This is undoubtedly the single biggest reason behind health insurance claim rejections across India. When you purchase a health insurance policy, you must fill out a proposal form. This form contains questions about your current health status and past medical history.

Several buyers hide existing conditions like diabetes, hypertension, asthma, or thyroid issues. Some do it intentionally to get away with paying a higher premium. Others simply hide it out of forgetfulness.

Insurance contracts work on the principle of utmost good faith. If you hide a medical condition at the time of purchase, it is treated as fraud or misrepresentation. During a claim, the insurance company reviews your hospital case history carefully.

Doctors can easily find out how old a disease is based on your body parameters and medical reports. If they discover a hidden disease, they will reject your claim instantly. They might even cancel your entire policy. For the unknown, the standard waiting period for pre-existing diseases is now cut short from the earlier four to three years.

Always be 100% honest about your health history. It is better to pay a slightly higher premium than to face a total rejection during a crisis. It is to be noted that dissatisfaction related to claim rejections arising out of non-disclosure of pre-existing diseases dropped from 33% in 2023 to 15% in 2024-25.

2. Raising a Claim During the Waiting Period

Every health insurance policy comes with specific waiting periods. You cannot buy a policy today and claim for a major surgery tomorrow.

Generally, there are three types of waiting periods in Indian health insurance policies:

• Initial Waiting Period:

This usually lasts for the first 30 days from the policy start date. No claims are allowed during this time, except for accidental hospitalizations.

• Specific Disease Waiting Period:

Most policies have a 1-year to 2-year waiting period for specific slow-growing ailments. Some of these conditions include cataracts, hernia, piles, joint replacements, and kidney stones.

• Pre-Existing Disease Waiting Period:

In case you have declared a disease like diabetes, you have to wait for 1 to 4 years before the policy covers any complications arising from it.

If you file a claim for these treatments before completing the specified timeline, your claim will be turned down. This counts as one of the most common health insurance claim rejection reasons among new policyholders. Always read your policy document to check these timelines.

3. Incomplete Documentation and Information Mismatch

Filing an insurance claim requires clear and proper paperwork. This is especially true for reimbursement claims, where you pay the hospital first and ask the insurer for money later.

Insurers require a detailed list of documents to process your payment. This includes the original discharge summary, itemized hospital bills, pharmacy receipts, diagnostic reports, and doctor’s prescriptions. If you miss submitting even a single mandatory report, your claim will stay on hold. If you fail to provide it within the given timeline, the company will reject it.

Furthermore, any mismatch in information can trigger an immediate rejection. Simple mistakes like misspelling the patient’s name, entering an incorrect policy number, or a mismatch between the doctor’s diagnosis and the medical bills will cause major issues. Always double-check every document before leaving the hospital.

4. Delay in Claim Intimation and Submission

Time is of the essence when dealing with health insurance. Every insurance company sets strict deadlines for informing them about a hospitalization.

For a planned hospital admission, you must intimate the insurer or their Third-Party Administrator (TPA) at least 48 to 72 hours in advance. In case of an emergency admission, you must inform them within 24 hours of hospitalization.

Similarly, there are tight deadlines for submitting the physical documents after discharge. This is usually within 7 to 30 days. If you delay informing the insurer or submit the documents late without a solid, legally valid reason, your claim will be rejected. Do not wait for weeks after getting discharged to start your claim process.

5. Claiming for Policy Exclusions and Sub-Limits

Many people assume that a health insurance policy covers every single expense inside a hospital. This is a huge misconception. Every medical policy has a strict list of permanent exclusions and sub-limits.

Permanent exclusions are medical expenses that the policy will never cover. Examples include cosmetic surgeries, dental treatments, fertility procedures, and injuries caused by adventure sports or self-harm. Trying to claim for these procedures will lead to a straight denial.

Additionally, you must watch out for room rent sub-limits. Many basic policies cap the daily room rent at 1% of the total sum insured. If your sum insured is ₹3 Lakh, your room rent limit is ₹3,000 per day. If you choose a private room that costs ₹6,000 per day, the insurer will apply a proportionate deduction. This means they will scale down your entire bill, leaving you to pay a massive chunk of money out of your own pocket.

How to Avoid Health Insurance Claim Rejections

To start with, important information related to claim settlement, complaint rates and renewals can be found in Schedule NL-47 of the insurers’ annual public disclosures. NL-47 is an IRDAI-mandated product-wise disclosure, helping buyers choose the specific policy they are considering.

Staying alert and informed is the best way to safeguard yourself against claim issues. Here is a quick checklist to keep in mind:
