Undisclosed Diabetes & Hypertension: Valid Insurance Rejection?

In the world of health insurance, few issues spark as much debate as the non-disclosure of pre-existing conditions. A common question arises: non disclosure of pre existing lifestyle diseases such as diabetes, hypertension cannot be a ground to decline Insurance claim. While this statement reflects a growing judicial trend favoring policyholders, the reality is more nuanced. Insurers often repudiate claims citing non-disclosure, but courts typically scrutinize whether these lifestyle diseases are truly material facts that influenced the risk assessment.

This blog post breaks down the legal principles, key court rulings, and practical advice based on established precedents. Remember, this is general information and not specific legal advice—consult a professional for your situation.

The Doctrine of Uberrima Fides: Utmost Good Faith in Insurance

Insurance contracts are based on uberrima fides (utmost good faith), requiring the insured to disclose all material facts—those that could influence a prudent insurer's decision on risk or premiums. 2020 5 Supreme 517 Failure to do so can lead to claim repudiation, especially if fraudulent or suppressive.

However, not every health condition qualifies as material. Common lifestyle diseases like diabetes and hypertension often fall into a gray area, particularly if well-controlled and without recent treatment.

Materiality of Lifestyle Diseases: Not Always Grounds for Repudiation

Courts have repeatedly held that diabetes and hypertension are prevalent and controllable, not automatically material unless linked to recent hospitalization or significant treatment. For instance, one ruling notes: From the aforesaid settled law, it is clear that the common lifestyle disease like diabetes and hypertension, cannot be treated as pre existing diseases, therefore, cannot be a ground of repudiation of the claim by Insurance companies. 2025 Supreme(Online)(SCDRC) 23084 2025 Supreme(Online)(SCDRC) 22699 2022 Supreme(Online)(Del) 7377

In another case, the court observed that treating such conditions as material would render mediclaim covers meaningless for most people.

• Key Test: Materiality depends on recency (e.g., hospitalization within 6-12 months).

• Controlled Conditions: Well-managed diabetes or hypertension without recent intervention is typically non-material.

Burden of Proof Lies with the Insurer

The insurer bears the onus to prove:1. The insured knowingly suppressed material facts.2. Such non-disclosure influenced the underwriting decision.

Without this, repudiation is unjustified. In a High Court writ under Article 226, the insurer's rejection for non-disclosure of hypertension was quashed, as without the knowledge of a pre-existing disease, it cannot be said that a material fact was suppressed. 2023 0 Supreme(Ker) 385 The court emphasized that policies are issued after medical checks, and sudden illnesses like brain hemorrhage cannot be retroactively deemed pre-existing.

Section 45 further protects claims after two years unless fraud is proven. The Insurance Company has not been able to prove that this information was fraudulently concealed by insured.

Landmark Court Rulings on Non-Disclosure

Judicial precedents tilt towards policyholders for common ailments:

• Non-Material Unless Recent: Diseases requiring hospitalization or treatment within a recent period (e.g., six months or a year) are more likely to be considered material. Ordinary cases do not warrant denial.

• No Suppression Evidence: Where pre-existing conditions were declared or no proof of knowledge exists, rejection is improper.

  Conversely, deliberate concealment of significant facts justifies repudiation.

• Consumer Forums Echo This: In a mediclaim dispute, the insurer failed to prove pre-existing diabetes/hypertension, violating natural justice by withholding TPA reports. The claim was allowed with compensation.

• Renewal Policies: Non-disclosure in renewals isn't fatal if no new material facts arise. Hence there is no question of non-disclosure for the purpose of renewed policy. 2019 Supreme(Online)(Bom) 2802

• Unawareness Defense: Every person suffers from symptoms of any disease without knowledge of same... Most of people are totally unaware of symptoms of disease that they suffer. Claims cannot be denied on policy clauses alone if unaware.

  Ashish Sharma VS United India Insurance Co. Ltd.

Other cases reinforce: Insurers cannot repudiate solely on lifestyle diseases without linking to claim cause or proving fraud. 2023 Supreme(Online)(NCDRC) 778

Practical Recommendations for Policyholders and Insurers

To navigate this:

For Policyholders:- Disclose all known conditions, especially recent treatments.- Retain medical records and proposal forms.- Challenge repudiations via Ombudsman or courts if no fraud proof.

For Insurers:- Define material facts clearly in policies.- Conduct thorough pre-issue checks.- Document how non-disclosure impacted risk.

Courts favor transparency: Both parties should maintain transparency and proper documentation.

• Insurers must prove fraud/materiality—burden not on insured.
• Section 45 offers protection post-2 years.
• Lifestyle diseases are common; courts prevent blanket denials.
