A health insurance policy is essential, especially if you already have a medical condition. It helps cover future treatment costs, but you must understand waiting periods and coverage limits. Being informed ensures you choose the right plan and stay financially protected.

This blog will explore the critical topic of health insurance coverage for pre-existing disease.

What is a pre-existing disease?

Pre-existing conditions are illnesses or diseases the insured person was diagnosed with or treated for up to 48 months before buying the policy. Some examples of pre-existing conditions are diabetes, cancer, high blood pressure, thyroid issues, asthma, etc.

Waiting period for pre-existing diseases

When you buy a health insurance policy, coverage for pre-existing diseases doesn’t begin right away. Insurers usually apply a waiting period, typically between 2 to 4 years, before they cover treatment for any illness you had before purchasing the policy. You have to pay for your treatment during the waiting period.

Waiting period length depends on the insurer and your health condition. Some policies may also allow reduced waiting periods for an extra premium. It’s important to read your policy terms carefully and choose a plan with a shorter waiting period if you already have known medical issues.

How a pre-existing disease affects your health insurance

A pre-existing disease can affect your health insurance in several ways. Insurers may apply a waiting period, typically 2 to 4 years, during which treatment for that condition won’t be covered. It can also lead to higher premiums or limited coverage, depending on the severity of the illness. Some plans may not cover specific pre-existing conditions at all. That’s why it’s important to disclose your medical history honestly and choose a plan that outlines how such conditions are handled.

Tips for buying health insurance with a pre-existing disease

The following are the tips for buying health insurance with a pre-existing disease:

  • Disclose your medical history honestly: Always share accurate details about your health to avoid claim rejections later.
  • Check waiting periods: Compare plans and choose one with a shorter waiting period for pre-existing conditions.
  • Check coverage inclusions: Make sure the policy clearly states which pre-existing conditions are covered and when.
  • Choose the right sum insured: Pick a sum insured that covers long-term treatment costs, especially for chronic illnesses.
  • Look for specialised plans: Some insurers offer plans specifically designed for people with pre-existing diseases.
  • Read the print: Read the policy terms carefully to understand all exclusions, limits and conditions.
  • Consider premium vs benefits: Don’t just go for the cheapest plan; balance premium cost with what the policy offers.
  • Consult an insurance advisor: If unsure, get professional help to pick a plan that suits your health and budget. Fill out the form on this page to get expert advice and personalised policy options that work best for you.

Things to know about pre-existing conditions in health insurance

Before buying health insurance with pre-existing disease cover, you must know the following aspects:

  • Health insurance companies may have varying definitions of what constitutes a pre-existing condition. Therefore, it is crucial to carefully read the policy document and comprehend the terms and conditions of the pre-existing condition clause.
  • The waiting period for pre-existing diseases can vary depending on the insurer, the condition and the plan you choose.
  • When you buy health insurance, you must fill out a proposal form that asks about your personal and medical details. Here, be honest and disclose your pre-existing conditions and other relevant health history. This will help you avoid any rejection or dispute at the time of claim settlement for pre-existing disease insurance.
  • You should also check the coverage and exclusions of the health insurance plan you are interested in. Some plans may have sub-limits or co-payments for pre-existing conditions, meaning you must bear part of the total cost.
  • Review your health insurance periodically and update it if there are any changes in your health status or requirements.

Conclusion

If one of your family members has a pre-existing disease, buying a health insurance policy for the family may seem challenging. However, with the right plan, you can get the protection you need. By understanding waiting periods, coverage details and comparing policy options carefully, you can make an informed choice that supports your health and finances. Always share your medical history truthfully and choose a plan that fits your long-term needs.
