When an Insurer Blames Your Lifestyle Without Proof
In March 2018, a man purchased a Star Health Family Health Optima Insurance Policy with a sum insured of Rs 3 lakh. Three months later, he developed a mouth ulcer. Upon examination at Mittal Institute of Medical Sciences in Raipur, the ulcer was found to be cancerous. He was diagnosed with squamous cell carcinoma, underwent treatment and surgery, and incurred medical expenses of around Rs 1.5 lakh.
When he submitted his reimbursement claim, Star Health rejected it. The insurer alleged that the disease was pre-existing, that he had suppressed material facts while obtaining the policy, and that his long history of consuming alcohol, chewing tobacco, and smoking attracted policy exclusions.
The Raipur District Consumer Commission did not accept this. On June 22, 2026, a bench of President Dakeshwar Prasad Shama and Members Nirupma Pradhan and Anil Kumar Agnihotri held Star Health guilty of deficiency in service and ordered the company to reimburse Rs 1.5 lakh with 6 percent annual interest, plus Rs 10,000 compensation for mental agony and Rs 5,000 towards litigation costs.
The Insurer's Defence: Allegations Without Evidence
Star Health's rejection rested on three pillars, all of which collapsed under scrutiny.
First, the insurer claimed the complainant had been consuming alcohol for 10 to 11 years, chewing tobacco for 15 to 20 years, and smoking for 5 to 6 years. It argued that smoking is the primary cause of cancer of the palate, and that medical expenses arising from this cause were excluded under the policy.
Second, the insurer alleged that the complainant had been suffering from ulcers for the past year but had not submitted investigation documents related to the same.
Third, it argued that before taking the policy, the complainant had symptoms of the disease which were not disclosed.
The commission examined each claim and found them all unsupported.
The Commission's Findings: No Proof, No Rejection
The commission noted that the certificate issued by the treating doctor clearly proved the complainant had approached the hospital for the first time on June 11, 2018, with the problem of mouth ulcers, and had been suffering from the ulcer for only the last 25 days. Upon examination, the ulcers were found to be cancerous. This clearly indicated that before June 11, 2018, the complainant did not know he had cancer.
Crucially, the commission observed that the insurer had not submitted any documents to support its claim that the complainant had been suffering from the disease for years. Without medical evidence linking the complainant's lifestyle habits to the development of oral cancer, the insurer's allegations remained just that, allegations.
The commission concluded that the insurance company was not justified in rejecting the complainant's medical reimbursement claim on the ground that he had concealed his medical condition. Such repudiation amounts to a deficiency in service as well as an unfair trade practice.
What This Ruling Shows
This decision shows how a consumer commission may scrutinise the evidence behind a pre-existing-disease, non-disclosure or lifestyle-based repudiation. Its findings are tied to the record in this case and should not be treated as a universal test for every health claim.
Undiscovered Illnesses Need Not Be Disclosed
The Commission relied on the treating doctor's certificate showing that the complainant presented with the ulcer shortly before diagnosis and that there was no evidence before it proving prior knowledge of cancer. Whether another undisclosed symptom or condition is material depends on the proposal, medical history, policy and evidence.
Lifestyle Habits Alone Do Not Justify Claim Rejection
Where an insurer relies on a lifestyle-related exclusion or says a habit caused the claimed illness, the exclusion and the supporting evidence must be examined together. In this case, the Commission found that Star Health had not produced medical material supporting the causal allegation it made.
In this case, Star Health alleged the complainant's oral cancer was caused by his tobacco, alcohol, and smoking habits. But it submitted no medical evidence, no doctor's opinion, and no diagnostic report proving this causal connection. The commission rightly held that allegations without proof are insufficient to deny a legitimate claim.
The Insurer Must Support the Ground It Invokes
An insurer relying on a pre-existing-disease, non-disclosure or exclusion defence must support that defence with evidence sufficient for the ground actually invoked. The burden and type of proof can vary with the policy wording, proposal disclosures and legal issue; the Raipur decision should not be converted into a single universal burden-of-proof formula.
Star Health failed this test. It made allegations but produced no proof. The commission treated this failure as fatal to the insurer's defence.
Common Tactics Insurers Use to Reject Claims on Lifestyle Grounds
At Tatkal Claims, we see insurers routinely invoke lifestyle habits to deny claims. Here is how the playbook works, and how to counter it.
If the insurer alleges non-disclosure of smoking or drinking, obtain the proposal form and verify what was asked and what was recorded. If an intermediary completed the form, preserve evidence of how the answers were obtained rather than assuming responsibility automatically lies with one side.
If the insurer says an excluded habit caused the illness, ask for the medical basis and the exact exclusion relied upon. The Raipur Commission rejected Star Health's allegation because the supporting evidence was not produced on the record before it.
Where a substance-use or similar exclusion is invoked, the outcome depends on the wording of the exclusion and the facts connecting it to the treatment claimed. Do not assume that a history of alcohol or tobacco use automatically proves the exclusion applies.
If the insurer alleges a pre-existing condition, compare the medical history with the current IRDAI pre-existing-disease definition, the proposal disclosures and the policy wording. The absence of prior diagnosis or treatment may be important, but each case turns on its own evidence.
What to Do If Your Claim Is Rejected on Lifestyle or Pre-Existing Disease Grounds
If your health insurance claim is rejected because of alleged lifestyle habits or a pre-existing condition, follow these steps.
First, demand a detailed written rejection letter citing the exact policy clause and the specific evidence supporting the rejection. Vague allegations are not legally sufficient.
Second, review your proposal form and policy document. Check whether you disclosed your habits accurately. Check whether the exclusion clause actually covers the specific illness you are claiming for.
Third, obtain a medical opinion from your treating doctor. A doctor's certificate stating that the illness was not pre-existing, or that there is no established causal link between your lifestyle habits and your specific diagnosis, is powerful evidence.
Fourth, file a complaint with the insurer's Grievance Redressal Officer. Attach your counter-evidence and demand a review. The officer must respond within 15 days.
Fifth, if the insurer does not reverse the rejection, escalate to the Insurance Ombudsman or the consumer court. The Raipur ruling shows that consumer forums will hold insurers accountable when they make allegations without proof.
The 60-Month Moratorium
Under the current IRDAI health-insurance framework, after 60 continuous months of coverage, including portability and migration, a policy and claim generally cannot be contested for non-disclosure or misrepresentation except for established fraud. If the sum insured is enhanced, a separate 60-month moratorium applies to the enhanced portion from the date of enhancement.
The moratorium materially limits later non-disclosure disputes, but it is not a blanket guarantee that every claim must be paid. Fraud and other applicable policy exclusions can still matter, and the scope of the moratorium must be read with the current IRDAI framework.
For claims arising before completion of the moratorium, the insurer may still investigate disclosure and exclusion issues, but its decision must be supported by the policy terms and evidence. The Raipur case is an example of a repudiation failing because the evidence relied upon did not substantiate the allegations.
Bottom Line
Star Health tried to reject a legitimate cancer claim by blaming the patient's lifestyle habits and alleging a pre-existing condition. It produced no medical evidence. It submitted no doctor's opinion. It made allegations and expected the patient to fold.
The Raipur Commission found that Star Health had not substantiated its pre-existing-disease and lifestyle allegations on the evidence before it. That case-specific failure of proof led to relief for the complainant; it does not mean every lifestyle-related or pre-existing-disease repudiation is invalid.
If a health claim is rejected for lifestyle habits, pre-existing disease or disputed non-disclosure, obtain the written ground, policy clause and supporting evidence, then use the insurer's grievance process and available external redress routes where the decision appears unsupported.
