Quick Summary

Health insurance portability gives you the freedom to switch from one insurer to another even if you suffer from pre-existing conditions that many providers might consider a health risk. To port health insurance with pre-existing conditions, you simply need to fill the IRDAI-mandated application form with all your identification and medical documentation in order.

 

Your health is your most valuable asset, and protecting it with the right insurance is essential, especially if you suffer from long-term conditions that you need frequent treatments for. When you are porting with a pre-existing condition, your new insurer will likely assess your health profile carefully, and you may face some challenges, but ultimately the process is simple and manageable.

 

What Is Health Insurance Portability?

The Insurance Regulatory and Development Authority of India (IRDAI) allows policyholders to smoothly switch their health insurance policy from one insurer to another while retaining benefits like served waiting periods and other credits from their old policy. 

 

This is especially helpful because pre-existing conditions often have long waiting periods, depending on your health care provider. Starting the long waiting periods from scratch can sit heavy on your chest and will be especially troublesome during an emergency. 

 

What Is A Pre-Existing Condition?

pre-existing condition, as defined by IRDAI, is a condition, ailment, injury or disease that is diagnosed by a physician within 1-3 years of the commencement of your policy. This means that you must be diagnosed within the given timeline to be eligible for a health care plan. 

 

Pre-existing conditions make portability more complex, as new insurers can often underwrite your application and may load premiums, apply exclusions or decline based on your health profile and claim history. Since they cannot deny waiting period credit for time already served, they retain the right to reject your portability requests if their risk assessment is unfavourable.

 

What Counts As A Pre-existing Condition? 

Long-term health issues that typically require an extended waiting period and attract premium loading fall under pre-existing conditions. The following are often considered pre-existing conditions by healthcare providers: 

 

How Do Pre-Existing Conditions Affect Waiting Periods In Health Insurance? 

The credits for waiting periods accumulate as you complete each year of your continuous coverage. For example, if you have served 2 years of the 3-year waiting period, you continue with those 2 years' worth of credits when you port your policy.

 

Your new health care provider cannot legally deny you these credits unless there was a lapse in your previous policy. Any discontinuity in your policy can result in the rejection of your portability application and may require you to start your waiting period from scratch.

 

The IRDAI framework ensures that if you have continuous coverage for 4 or more years, then the pre-existing disease exclusion clause will become inapplicable. This is irrespective of whether you have coverage from a single or multiple insurers. 

 

What Are The Challenges You Might Face When You Port Health Insurance With a Pre-existing Condition?

You might face the following challenges when you decide to port your health insurance plan if you have pre-existing conditions: 

  1. Reluctance to accept from healthcare providers: Health insurance companies are generally hesitant to accept policyholders with pre-existing conditions because they are likely to present a higher financial risk.
  2. Higher premium: Many policies may quote you a higher premium if you have a pre-existing condition. They may also apply premium loading, as a pre-existing condition poses higher health risks.
  3. Risk of permanent exclusions: Your new provider can underwrite and may apply exclusions or decline your portability request due to your health profile. If you apply for a big claim right before porting, the chances of you getting an approval are low.
  4. Coverage gaps: If you end your old policy before you officially port, you can face coverage gaps, which can be harmful if a sudden emergency arises. It is better to keep the old policy active until the new plan is issued to avoid any gaps in coverage.
  5. Incomplete medical disclosure: Not properly disclosing your medical history can invalidate portability benefits, like credits for waiting periods on pre-existing conditions. Failing to disclose pre-existing conditions can lead to the rejection of your claim and even the cancellation of your policy.

 

A Step-by-Step Guide To Port Health Insurance When You Have A Pre-Existing Condition

Step 1: Complete medical records

You must collect all your essential medical records that relate to your pre-existing condition. This includes documents like:

  • Diagnostic reports
  • Test results
  • Doctor’s letter
  • Discharge summary
  • Prescription history 

Step 2: Review current policy

It is essential that you review your current health insurance policy and confirm your waiting period credit. You will also need a letter from your current healthcare provider that confirms these details to have a smooth portability process.

Step 3: Research and shortlist insurers

You should research and read the fine print on policies to verify waiting periods on pre-existing conditions. Find insurers that do not underwrite your waiting periods or include unnecessary premium loadings. Shortlist a couple of options before renewing your existing policy.

Step 4: Submitting portability request form

You must inform your current insurer about the probability prior to 45 days of your policy renewal. You should submit the portability request to your new provider before this time period to have a smooth portability process.

Step 5: Complete the proposal form

When you apply for portability with a new insurer, you should make sure that you carefully fill out the proposal form. You should also disclose your medical history accurately to your new provider to avoid any rejections or invalidation of portability benefits.

Step 6: Take a medical exam if required

Your new healthcare provider can ask you to take a medical examination to understand your health profile better and assess the risks before approving your portability request. This can be made mandatory by some private insurers for policyholders who are above 45 years old and may bring significant health risks.

Step 7: Confirmation

The last step in the process is to confirm your new policy is active before you end your old one to avoid any coverage gaps. It is okay to have two plans overlap for a small period of time rather than not being covered in case emergencies arise.

 

What Documents Will You Need When You Port Health Insurance?

You will need the following documents when you are porting your policy:

 

Documents 

Purpose

Detailed claim history

Identity proof

Your PAN, Aadhaar, passport, etc., help identify you in the system and confirm your identity so that your new insurer can process your plan under your account.

 

What Are Key Factors To Evaluate In A New Policy?

You should check whether the new insurer covers your specific pre-existing condition and evaluate the claim settlement ratio for PED claims.

 

Always select a plan that offers shorter waiting periods so that you can minimise the time without where you don't have PED coverage. Some plans offer reduced waiting periods from 36 months to 24 months but for an additional premium.

 

The best health insurance plans for pre-existing diseases cover diabetes, BP, cholesterol, asthma, thyroid and kidney stones comprehensively.

 

What is the Role of an Insurance Broker in Finding the Best Plan for Pre-Existing Conditions
