The Hidden Risks in Your Policy
Some diseases carry higher risk—and insurers often treat them differently. Imagine being hospitalized for a complication from a long-standing condition like diabetes, only to have your health insurance claim denied because it was deemed “pre-existing.” In India, where chronic illnesses affect millions, understanding these nuances can mean the difference between financial security and crippling medical bills. With health insurance claims worth Rs 26,000 crore denied in FY24 alone—a 19% rise from previous years—policyholders are increasingly facing rejections due to exclusions and waiting periods. This article dives deep into the common conditions flagged by insurers, how they’re handled, real-world use cases, legal precedents, and practical tips to safeguard your coverage.
Common Partial or Full Exclusions: A Comprehensive List
Health insurance policies in India, regulated by the Insurance Regulatory and Development Authority of India (IRDAI), categorize exclusions into temporary (often with waiting periods) and permanent ones. Pre-existing diseases (PEDs) are defined as any condition diagnosed or treated within 36 months before policy purchase, down from 48 months per IRDAI’s 2024 guidelines. While PEDs are typically covered after a waiting period, permanent exclusions are never covered, regardless of time.
Here’s an expanded list of common conditions often subject to partial (waiting periods or sub-limits) or full (permanent) exclusions, based on IRDAI standards and policy analyses. This goes beyond basics like diabetes and hypertension to include all frequently cited ones from insurer documents and regulatory lists.
Pre-Existing Diseases (PEDs) with Partial Exclusions (Covered After Waiting Period)
These are chronic or long-term conditions that insurers “red-flag” but cover post-waiting (usually 1-3 years, max 3 years per IRDAI from April 2024). Common examples include:
| Condition | Description/Examples | Typical Waiting Period |
| Diabetes (Type 1 & 2) | Includes complications like neuropathy or retinopathy. Often requires disclosure at purchase. | 1-3 years |
| Hypertension (High Blood Pressure) | Linked to heart risks; may involve premium loading if severe. | 1-3 years |
| Asthma & Respiratory Disorders | Chronic bronchitis, COPD; coverage for exacerbations after waiting. | 2-3 years |
| Thyroid Disorders | Hypo/hyperthyroidism; routine meds may not be covered initially. | 1-3 years |
| Heart Conditions | Coronary artery disease, angina, prior heart attacks. | 2-4 years (now max 3) |
| Cancer (Various Types) | Breast, lung, prostate; post-diagnosis treatments covered after waiting if not terminal. | 2-3 years |
| Kidney Diseases | Chronic kidney disease, dialysis needs. | 2-3 years |
| Liver Disorders | Cirrhosis, hepatitis (non-alcohol related). | 2-3 years |
| Arthritis & Joint Issues | Rheumatoid arthritis, osteoarthritis. | 1-3 years |
| Hyperlipidaemia (High Cholesterol) | Often bundled with metabolic syndrome. | 1-2 years |
| Obesity-Related Conditions | Metabolic syndrome, sleep apnea (treatment for obesity itself excluded). | 2-3 years |
| Epilepsy & Neurological Disorders | Seizures, migraines if chronic. | 2-3 years |
| Mental Health Conditions | Depression, anxiety (IRDAI mandates coverage from 2020, but with waiting). | 2-3 years |
| Congenital Internal Anomalies | Heart defects present from birth but internal. | 2-3 years if disclosed |
Sources indicate these account for most PED claims, with diabetes and hypertension affecting over 10% of India’s adult population.
Permanent or Full Exclusions
These are never covered, as per IRDAI’s standardized list (updated 2019-2023), focusing on non-medical, elective, or high-risk items. HIV/AIDS and certain congenital anomalies often fall here if not classified as PED.
| Condition/Treatment | Description/Examples | Reason for Permanent Exclusion |
| HIV/AIDS & STDs | Full treatment excluded in many policies; complications may be denied. | High long-term costs; some policies treat as PED but often permanent. |
| Congenital External Anomalies | Visible birth defects like cleft lip (internal may be PED). | Considered cosmetic or non-life-threatening. |
| Obesity/Weight Control Treatments | Bariatric surgery, diet programs. | Elective, not medically necessary. |
| Gender Change Treatments | Hormone therapy, surgeries. | Elective procedures. |
| Cosmetic & Plastic Surgeries | Unless accident-related (e.g., burns). | Aesthetic, not health-driven. |
| Infertility & Sterility | IVF, fertility drugs. | Non-essential for survival. |
| Maternity & Childbirth (in basic plans) | Delivery, prenatal (covered in riders). | Specific exclusion unless added. |
| Self-Inflicted Injuries/Alcohol/Drug-Related | Overdose, addiction treatments. | Preventable/behavioral risks. |
| Dental Treatments | Unless injury-related. | Separate policies often needed. |
| Unproven/Experimental Treatments | Alternative therapies like Ayurveda (partial in some). | Lack of evidence-based efficacy. |
| War/Terrorism-Related Injuries | Any condition from conflict. | Force majeure clause. |
| Sarcoidosis & Malignant Neoplasms (if advanced) | Some rare chronic auto-immune or cancers if pre-policy terminal. | High-risk, undisclosed. |
From analyses, permanent exclusions like HIV/AIDS appear in 80% of standard policies, though IRDAI prohibits denying policies outright for PEDs.
How These Conditions Are Treated by Insurers
Insurers handle high-risk diseases through a mix of mechanisms to balance risk and affordability:
- Permanent Exclusions: As listed above, these are outright denied. For instance, HIV/AIDS treatments are often excluded entirely, even post-waiting, due to lifelong management needs.
- Waiting Periods: PEDs like diabetes or hypertension are covered after 1-3 years. IRDAI’s 2024 rules cap this at 36 months, and claims cannot be rejected for ailments predating 36 months if undisclosed unintentionally. Some plans offer zero-waiting for accidents but not chronic issues.
- Higher Premiums or Co-Pays: For disclosed PEDs, premiums may increase by 10-50% (loading). Co-pays (e.g., 20% patient share) apply to chronic claims, especially in senior plans. Obesity-related claims might have sub-limits.

Legal note: IRDAI mandates no policy denial for PEDs, but non-disclosure can lead to rejection.
Why These Diseases Are Red-Flagged
Insurers flag these due to long-term costs and recurrence. Chronic conditions like diabetes lead to recurring hospitalizations (e.g., Rs 5-10 lakh annually for complications), pushing claim ratios up. Recurrence rates: Diabetes complications recur in 30-40% of cases; heart diseases in 20% post-event. Permanent exclusions like cosmetic or drug-related prevent moral hazard, while PED waiting periods allow risk assessment.
Real-World Use Cases and Legal Findings
To authenticate, here are examples and court rulings:
- Use Case 1: Diabetes Claim Denial: A Kerala man’s Rs 5 lakh bowel surgery claim was denied citing a 12-year-old pre-existing condition (unrelated laparotomy). The insurer (unnamed) misinterpreted PED clauses, leading to a consumer forum appeal.
- Use Case 2: Heart Surgery Rejection: A policyholder’s coronary bypass claim was denied for undisclosed hypertension. The consumer won reimbursement plus compensation via the Consumer Disputes Redressal Commission, as the condition was not “material” to the surgery.
- Legal Finding: Widow’s Rs 28 Lakh Win (2024): HDFC ERGO denied a widow’s claim for her husband’s treatment, citing undisclosed diabetes. The Delhi State Consumer Commission ruled the denial wrongful, awarding Rs 28 lakh, stating pre-existing conditions can’t be a “free pass” for rejections if waiting periods are met.
- Supreme Court Precedent (Multiple Cases): In cases like Prabhatha Shetty vs. Apollo Munich (2022), courts overturned denials for PEDs if not proven as “pre-existing” beyond 36 months, emphasizing IRDAI’s non-repudiation after 8 years of policy. Another ruling: Claims can’t be denied for mental health exclusions post-IRDAI’s 2020 mandate.
- Group Case Study: Chronic OOP Expenses: A 2012 study showed chronic patients in India face 20-30% out-of-pocket costs despite insurance, due to exclusions, pushing 5-10% into poverty.
These highlight that while denials are common (5-10% rate), appeals succeed 60-70% of the time if policy terms are challenged.
Tips for Policyholders
- Opt for Disease-Specific Riders: Add-ons like Star Health’s Diabetes Safe (covers from Day 1 for diabetes), Cardiac Care, or Cancer Secure plans provide lump-sum payouts or waived waiting. Critical Illness Riders (e.g., ICICI Pru covers 34 illnesses like cancer/heart) pay 25-100% sum insured. Other riders: Maternity, Hospital Cash (daily allowance), or PED Waiver (reduces waiting for extra premium).
- Disclose Fully: Non-disclosure leads to 40% of denials; use IRDAI’s 36-month look-back.
- Compare Plans: Use portals like Algates Insurance; prioritize low-waiting (e.g., ACKO’s zero-waiting for some).
- Appeal Denials: Start with insurer grievance, then IRDAI Ombudsman or Consumer Forum—success rate high for wrongful PED calls.
Takeaway: Empower Your Choices
If you already live with a chronic condition, compare insurers on how they treat it, not whether they mention it. Focus on waiting periods, riders, and legal protections under IRDAI to avoid surprises. With rising chronic diseases in India, proactive planning ensures your policy works when you need it most.
