Why Health Insurance Claims Are Rejected

“You think you’re covered — wait until your insurer says no.”

Health insurance is sold as a risk cover and a safety net, but for countless policyholders the real shock comes not from the illness, but from the rejection letter of the health insurance company. In India, insurers proudly advertise claim settlement ratios above 90%, which is Rs 1.89 Crores claims settled through Cashless mode for an amount of Rs. 62537 Crores, 58% by volume and 66% by value are settled by Cashless mode. This was reported in the year 2024-25, the insurance companies have settled 3.26 Crore Claims for an amount of Rs. 94248 Crores. Yet I have observed thousands of families land up with shock after their claims are rejected. The truth is sobering: most denials aren’t random. They stem from avoidable mistakes, overlooked fine print, or procedural lapses.

The most recent development is our traditional healthcare treatments, which is also covered under the health insurance coverage, without any exclusion and treatment parity. Today Ayush treatment is at par with Allopathy treatment in India, which is an unique feature in our country. Of course, the awareness about such facilities are lacking and the Ministry of Ayush, Government of India has established a Helpline 1800110008 to facilitate the Ayush Hospitals and patients to derive all the benefits, without any discrimination.

Let me share with you the most common reasons behind claim rejection — and illustrating them with real‑world examples — policyholders can learn how to protect themselves and ensure their coverage works when it matters most.

10 Common Pitfalls & How to Avoid Them

1. Non‑Disclosure of Pre‑Existing Conditions

Health insurance thrives on transparency. Yet one of the most common — and costly — mistakes policyholders make is failing to disclose pre‑existing medical conditions due to mis selling adopted by the agents. Concealing issues like diabetes, hypertension, or past surgeries may seem harmless at the time of purchase, but insurers treat it as misrepresentation.

“What you hide today can come back to haunt you tomorrow.”

Case in Point: 

A 45‑year‑old in Delhi underwent bypass surgery. His claim was rejected outright when the insurer discovered he had not disclosed his long‑standing hypertension. The company argued the surgery was directly linked to the undisclosed condition.

Lesson: Always disclose your medical history honestly, even if it means paying a higher premium. The short‑term cost is far better than the long‑term shock of a rejected claim.

2. Claims During Waiting Period

Health insurance policies don’t always provide instant protection. Most impose waiting periods for certain illnesses, treatments, or pre‑existing conditions. Maternity benefits may require two to four years, while pre‑existing conditions often demand two to three years before coverage kicks in.

“Buying late means waiting longer.”

Case in Point: 

A young couple in Lucknow filed a claim for maternity expenses within one year of purchasing their policy. The insurer rejected it, citing the two‑year waiting period clause.

Lesson: Plan coverage early. Buy health insurance well before you anticipate medical needs, so the waiting clock runs out before you need to file a claim.

3. Treatment Not Covered (Policy Exclusions)

Every health insurance policy comes with exclusions — treatments or conditions that simply aren’t covered. Cosmetic surgery, dental procedures, infertility treatments, and certain alternative therapies often fall outside the safety net. Many policyholders discover this only when their claim is denied.

“The fine print decides your fate.”

Case in Point: 

A patient in Mumbai underwent bariatric surgery to address obesity. When he filed a claim, the insurer rejected it outright, pointing to the exclusion clause that ruled out weight‑loss procedures.

Lesson: Never assume all treatments are covered. Read the exclusions carefully before purchase and consider add‑on riders if you anticipate specific medical needs.

4. Incomplete or Incorrect Documentation

Health insurance claims live and die by paperwork. Hospital bills, discharge summaries, prescriptions, and diagnostic reports must all align perfectly. Even small errors — a misspelled name, mismatched dates, or missing signatures — can derail an otherwise genuine claim.

“One wrong line on paper can cost lakhs.”

Case in Point: A claim in Ghaziabad was rejected because the discharge summary listed the wrong patient’s name. Despite the treatment being genuine, the mismatch raised red flags and the insurer refused to settle.

Lesson: Double‑check every document before submission. Keep both digital and physical copies and ensure hospital staff issue correctly filled records. Accuracy is your strongest ally in claim approval.

5. Delayed Intimation to Insurer

Health insurance isn’t just about treatment — it’s about procedure. One of the most overlooked requirements is prompt intimation to the insurer or TPA. Most policies demand that hospitalization be reported within 24 hours. Delay in communication, even in genuine emergencies, can give insurers grounds to reject a claim.

“A stitch in time – saves nine.”

Case in Point: A family in Jaipur informed their insurer only after discharge. Despite the hospitalization being genuine, the claim was denied because the policy required intimation within 24 hours of admission.

Lesson: Always notify your insurer or TPA immediately when hospitalization occurs. A quick phone call or online intimation can save you from unnecessary rejection.

6. Treatment at Non‑Network Hospitals

Cashless claims are a major convenience — but they only work at hospitals within the insurer’s approved network. Opting for treatment at a non‑network hospital often means paying upfront and struggling later with reimbursement, which may be delayed or even denied. However, the insurance regulator IRDAI has now directed all the health insurance companies through a master circular that all claims need to be Cashless and approvals given within a stipulated time, which was missing earlier. Even non-network hospitals are bound to provide Cashless treatment for health insurance policy holders. To my surprise, data has revealed that 50% of the hospitals in our country do not want to entertain health insurance policyholders and are not interested in dealing with the health insurance companies due to several pre-conditions put forth by the insurance companies.

“The wrong hospital can empty your wallet.”

Case in Point: A patient in Noida underwent emergency surgery at a non‑network hospital. His family expected cashless settlement, but the insurer rejected the claim, leaving them to bear the immediate financial burden.

Lesson: Always check your insurer’s hospital network before admission. In emergencies, inform the insurer quickly and clarify reimbursement procedures to avoid unpleasant surprises. However, now it is Chashless for all Anywhere as per IRDAI master circular.

7. Fraudulent or Inflated Claims

Insurers are vigilant against fraud — inflated bills, fake documents, or unnecessary procedures. Even genuine patients can suffer if they’re treated at hospitals flagged for malpractice. Suspicion alone can stall or sink a claim.

“If it looks fake, it won’t fly.”

Case in Point: A hospital in Haryana was blacklisted after insurers discovered inflated billing for routine procedures. Patients treated there faced claim rejections, even when their treatments were legitimate.

Lesson: Always ensure your bills and documents are genuine, accurate, and reflect actual treatment. Avoid hospitals with a reputation for malpractice — their record can jeopardize your claim. Ensure bills are genuine and match actual treatment received.

8. Policy Lapse Due to Non‑Payment of Premium

Health insurance only works if the policy is active. Missing premium payments, even by a few days, can cause the policy to lapse — leaving you unprotected when you need it most. Insurers treat lapses strictly, and claims during this period are automatically rejected.

“Missed payments mean missed protection. No Premium = No Protection”

Case in Point: A businessman in Ghaziabad missed his premium payment by two weeks. Unfortunately, he was hospitalized during the lapse, and the insurer denied his claim outright.

Lesson: Set reminders or opt for auto‑debit facilities to ensure premiums are paid on time. A small oversight can cost you financial security when it matters most.

9. Hospitalization Not Meeting Criteria

Many health insurance policies require a minimum hospitalization period — often 24 hours — for claims to be valid. Exceptions exist for listed day‑care procedures, but if your treatment doesn’t fall under those, a short stay can mean no coverage.

“Short Stays, Big Problems.”

Case in Point: A patient in Delhi underwent cataract surgery and was discharged the same day. His claim was rejected because the policy did not cover day‑care procedures, and the hospitalization was under 24 hours.

Lesson: Always check whether your policy covers day‑care treatments. If not, ensure hospitalization meets the minimum criteria, or consider upgrading your plan to include day‑care coverage.

10. Failure to Respond to Insurer Queries

During claim processing, insurers often seek clarifications — additional medical reports, test results, or explanations of treatment. Ignoring these requests, or responding too late, can stall the process and ultimately lead to rejection.

“Silence Can Cost You. No reply = no payout.”

Case in Point: A family in Meerut failed to respond to repeated insurer queries about their medical documentation. With no clarifications provided, the insurer closed the case and denied the claim.

Lesson: Track your claim status closely. Respond promptly to every query and keep copies of all correspondence. Timely communication can be the difference between approval and rejection.

Conclusion

Health insurance is a lifeline — but only if claims are honoured. Most rejections are preventable with awareness, transparency, and timely action. By understanding the top 10 reasons for claim rejection, illustrated through real‑world case studies, policyholders can safeguard themselves against unpleasant surprises. And if claims are unfairly denied, legal remedies through the Insurance Ombudsman Scheme, IRDAI, or consumer commissions provide a path to justice. Do not become victims of agents and deal directly with the insurance companies as has been observed, few blacklisted hospitals connive with the insurance agents to mislead the policyholders to deny claims and force patients to pay directly by making false promises on reimbursements.

The takeaway is simple: read carefully, disclose honestly, act promptly, and know your rights. Health insurance works best when policyholders and insurers operate on trust, clarity, and accountability.
