When buying health insurance, one of the most critical factors to consider is the presence of pre-existing diseases (PEDs). These are medical conditions or illnesses you may have before purchasing a health insurance policy. Examples include diabetes, high blood pressure, thyroid issues, or heart problems.
Insurance providers evaluate your health history during policy issuance. If any illness is diagnosed before buying the policy, it is declared a pre-existing condition. This can directly affect your health insurance coverage, especially in terms of premium amount, waiting period, and exclusions.
How Do Waiting Periods Affect Health Insurance Coverage?
A waiting period in health insurance is when a policyholder cannot claim insurance benefits for treatment related to pre-existing diseases. This is one of the most crucial aspects affecting your health cover's utility.
There are typically three types of waiting periods in health insurance:
-
Initial Waiting Period
Usually 30 days from the policy start date. No claims are allowed except for accidents during this period.
-
Waiting Period for Pre-Existing Diseases
Generally ranges from 2 to 4 years depending on the insurer. During this time, treatment costs related to pre-existing conditions are not covered.
-
Specific Disease Waiting Period
Covers conditions like hernia, piles, and cataracts. This is separate from PEDs and usually lasts 1-2 years.
For instance, if you have diabetes and purchase a plan with a 3-year waiting period for PEDs, your insurer won’t cover diabetes-related hospitalisation until that period is over.
To ensure uninterrupted coverage, many insurers offer options like:
- Reduced waiting periods for higher premiums.
- Waivers after continuous renewal for a certain number of years.
Understanding the waiting period is essential because even though a policy technically includes your PED, it won’t offer financial protection until this duration passes.
Best Health Insurance Plans for Pre-Existing Conditions
Not all insurance policies treat pre-existing diseases the same. Some health insurance plans offer faster inclusion of PEDs, lower waiting periods, or additional benefits tailored to chronic conditions. Here's a look at some of the best options available in India:
1. Star Health – Star Health Diabetes Safe Insurance
- Specifically designed for people with Type 1 or Type 2 diabetes.
- Coverage includes outpatient consultations and diagnostics.
- No waiting period for diabetes-related hospitalisation.

2. Care Health Insurance – Care Freedom Plan

3. Niva Bupa – Health Companion Plan

5. Aditya Birla Activ Health Platinum

While choosing a plan, always:
- Read the policy wording carefully.
- Understand the waiting period clauses.
- Opt for insurers with high claim settlement ratios and good customer service.
If you already have a health policy, consider porting to a better plan. You can shift from one insurer to another while maintaining the credit of the waiting period already served.
Pre-existing diseases should not discourage you from buying health insurance. With increasing awareness and medical advancements, many insurers are now offering plans tailored for chronic illnesses. However, knowing how waiting periods work is vital. A policy may list coverage for your condition but will not pay for related treatment unless the waiting period has passed. Shorter waiting periods, disease-specific plans, and regular renewals can help overcome this hurdle.
