Diabetes, Hypertension and Health Insurance Claims: What a Recent Consumer Commission Order Examined

A recent consumer commission order in Delhi has brought renewed attention to an issue that concerns thousands of health-insurance policyholders: Can an insurer reject a mediclaim simply because the patient has diabetes or hypertension?

The District Consumer Disputes Redressal Commission, West Delhi, recently directed Care Health Insurance to pay approximately ₹2.18 lakh to a policyholder whose claim following a heart attack had been rejected on the basis of alleged pre-existing diabetes and hypertension. The order, passed on 7 August 2026, found that the insurer had not produced sufficient evidence to establish its case. 

The case is important, but it should not be interpreted to mean that an insurer can never reject a claim involving diabetes or hypertension. The decision primarily highlights the importance of evidence, policy terms and establishing a genuine connection between an alleged pre-existing condition and the treatment for which the claim is made.

What Happened in the Case?

The policyholder had taken a health-insurance policy from Care Health Insurance in 2018, with coverage of ₹5 lakh for the relevant policy period.

In April 2019, he was admitted to Manipal Hospital after suffering a myocardial infarction. He was diagnosed with acute lateral-wall myocardial infarction and coronary artery disease and underwent angioplasty with stenting.

He subsequently submitted a claim of approximately ₹1.93 lakh for the treatment.

The insurer rejected both the cashless and reimbursement claims, citing pre-existing Type 2 diabetes and hypertension. 

The dispute before the consumer commission therefore centred on a crucial question: Had the insurer actually established that these conditions were pre-existing and that they justified rejection of the heart-treatment claim?

What Evidence Did the Insurer Rely On?

The commission examined the evidence submitted by both sides.

Care Health Insurance relied, among other things, on a medical-history document and hospital progress notes that recorded the patient as having diabetes for approximately one year and hypertension for approximately three years.

However, the commission found problems with the evidence.

The medical-history document relied upon by the insurer was reportedly unsigned, unstamped and did not identify the patient, treating doctor or hospital. The insurer also did not examine a doctor from the hospital whose records it relied upon to establish the alleged medical history. 

The complainant, on the other hand, produced a discharge summary that did not record a past history of diabetes or hypertension. He also produced a certificate from the operating surgeon at Manipal Hospital stating that he was normotensive and non-diabetic at the time of his heart surgery. 

This difference in evidence became central to the Commission's decision.

Why the Commission Rejected the Insurer's Argument

The Commission found that the insurer had failed to substantiate its allegation that the patient had the alleged pre-existing conditions in a manner sufficient to justify repudiation of the claim.

An important aspect of the decision was the distinction between a medical condition existing at some point in a person's medical history and a proven pre-existing disease that falls within the relevant exclusion or waiting period of an insurance policy.

The Commission referred to earlier decisions of consumer fora, including cases concerning diabetes and hypertension.

In Satish Chandra Madan v. Bajaj Allianz General Insurance Co., the National Consumer Disputes Redressal Commission had observed that hypertension is a common condition that can be controlled with medication and that having hypertension does not necessarily mean that a person will suffer a heart attack. 

Similarly, previous consumer decisions have held that the mere presence of diabetes or hypertension does not automatically establish that a subsequent heart condition is a pre-existing disease or a complication of that condition.

What Did the Consumer Commission Order?

The West Delhi Commission directed Care Health Insurance to pay the full claim amount of ₹1,93,234, along with 6% annual interest from the date of filing of the complaint until realisation.

It also awarded ₹25,000 towards compensation for mental and physical harassment, including litigation costs.

The total amount therefore comes to approximately ₹2.18 lakh, subject to the applicable interest calculation. The insurer was directed to comply within 30 days of receiving the order.

Does This Mean Diabetes or Hypertension Can Never Lead to Claim Rejection?

No. This is an important distinction.

The recent decision should not be read as saying that insurers are prohibited from considering diabetes, hypertension or other pre-existing conditions.

Health-insurance policies commonly contain provisions relating to pre-existing diseases, waiting periods, exclusions and disclosure of medical history. If an insurer can establish that a condition was genuinely pre-existing, was relevant under the policy terms and falls within an applicable exclusion or waiting period, the claim may be affected.

The important issue is whether the insurer can prove the basis on which the claim is being rejected and whether that basis is actually supported by the policy.

In other words, the existence of diabetes or hypertension alone does not automatically answer the question of whether a particular claim is payable.

The Importance of Disclosure When Buying Insurance

The case also highlights an equally important responsibility for policyholders.

When purchasing health insurance, applicants should provide complete and accurate information about their medical history. Concealing a known condition can create serious difficulties when a claim is subsequently made.

Policyholders should retain copies of their proposal form, medical declarations, policy documents, medical reports and correspondence with the insurer.

This documentation can become extremely important if a claim is later disputed.

A Larger Lesson for Mediclaim Policyholders

The Delhi consumer commission's decision reinforces a broader principle: insurance claims must be assessed on the basis of evidence and the actual terms of the policy, rather than assumptions about a patient's medical history.

At the same time, the judgment is not a blanket prohibition on rejecting claims involving diabetes or hypertension.

Every mediclaim dispute has to be examined on its own facts, including the policy wording, medical records, disclosure at the time of obtaining the policy, waiting periods and the evidence relied upon by the insurer.

For policyholders, the message is simple:

Having a medical condition does not automatically make every subsequent illness a pre-existing disease. But accurate disclosure and careful documentation remain essential.

As health-insurance claims become increasingly complex, understanding both the medical evidence and the legal terms of the insurance contract can make a significant difference when a claim is disputed.
