Mechanics of Health Insurance Portability in India

Portability is the legal right to transfer your "Time Credits" (Waiting Periods for Pre-Existing Diseases) from Insurer A to Insurer B. It is not a transfer of your premium or policy features. You must apply at least 45 days before renewal.

Most users misunderstand Portability as a "Copy-Paste" of their old policy. It is not. It is a fresh application where the new insurer assesses your current health risk but is legally mandated to respect the "Time" you served with the previous insurer.

Checklist

• Existing Policy Schedule (Previous 3 years if available).
• Renewal Notice (Proof of active status).
• Claims History (Request this from your current insurer's portal).
• The Hidden Requirement: The "15-Day Deemed Acceptance" Timer. Under the IRDAI Master Circular (2024/2025), if the new insurer receives your data from the old insurer and fails to accept or reject within 15 days, the proposal is deemed accepted by default. You must track this date.

Step-by-Step Guide

• Step 1: The 45-Day Trigger
  You must initiate the request 45 to 60 days before your policy expiry. If you apply 20 days before expiry, the system will auto-reject you.
  Action: Fill the "Portability Form" and "Proposal Form" at the new insurer.
• Step 2: Data Exchange (The Backend Handshake)
  The new insurer logs a request on the IIB (Insurance Information Bureau) portal. Your old insurer has 72 hours to upload your medical and claims history. You do not control this, but you must monitor it.
• Step 3: Fresh Underwriting
  The new insurer assesses your current health. If you developed Diabetes in Year 4 of your old policy, the new insurer can load your premium or even reject the port. Portability guarantees credit for time served, not acceptance of risk.
• Step 4: The Credit Transfer
  If accepted, your "3-Year Waiting Period" for Pre-Existing Diseases (PED) is waived if you have already held a policy for 3+ years. This is the "Gold" you are carrying with you.

How It Works & Hidden Details
The "Sum Insured" Trap:
Portability credit applies *only* to the Sum Insured (SI) you held with the previous insurer.
Example: You had ₹5 Lakhs SI for 4 years. You port to a new insurer and upgrade to ₹10 Lakhs.
Result: The waiting period is waived for the first ₹5 Lakhs. For the *additional* ₹5 Lakhs, the standard waiting periods (2-3 years) will apply from Day 1.

The "3-Year PED" Rule (2024/2025 Update):
Effective April 1, 2024, IRDAI reduced the maximum waiting period for Pre-Existing Diseases from 4 years to 3 years. This benefits you during portability. If you have completed 36 months with Insurer A, Insurer B cannot impose any PED waiting period on the ported sum insured.

The Moratorium Shield:
The "Moratorium Period" (now 5 years under 2026 context) is also portable. If you have completed 5 years of continuous coverage, the new insurer cannot reject claims based on "Non-Disclosure" unless they prove fraud. You carry this "immunity" with you.

Things to Watch Out For

• Risk 1: The "NCB" Loss. Most insurers do not port your No Claim Bonus (NCB) as "Bonus." They might allow you to merge it into the Base Sum Insured, but this usually spikes the premium because your "Base Coverage" has technically increased.
• Risk 2: The "Underwriting" Rejection. Do not cancel your old policy until the new one is issued. If Insurer B rejects your portability request (which they can do if you are high risk), you must renew with Insurer A immediately to avoid a "Break in Policy," which destroys all accumulated credits.

Frequently Asked Questions

• Q: Can I port from a Senior Citizen Plan to a normal plan?
  A: Yes, but difficult. Senior specific plans often have different risk pools. The new insurer will likely mandate a medical test and may charge a heavy loading fee.
• Q: Can I port a Group Policy (Employer) to Retail?
  A: Yes, but you lose the "Waiting Period" credit unless you port specifically into the same insurer's retail plan first (Migration), then port out later.

Update: Additional Details & Recent Changes

• NCB Transfer Parity:
  Under the 2024-25 Master Circular, you are entitled to transfer the cumulative No Claim Bonus (NCB) from your previous insurer. Most insurers now offer this by increasing your new "Base Sum Insured" by the amount of the accrued bonus, effectively giving you a higher "Starting SI" in the new policy without the typical waiting periods associated with a fresh SI upgrade.
  
• Acquiring Insurer Decision Timeline:
  The mandatory turnaround time for the new insurer has been tightened. Once the acquiring insurer receives the required data from the existing insurer via the IIB portal (which must happen within 72 hours), they must communicate their decision to accept or reject the proposal within 5 days. If they fail to do so, the 15-day "Deemed Acceptance" rule still acts as the final statutory backstop.
  
• Grace Period for Porting:
  If the portability process is still underway (e.g., pending medical tests or data exchange) and your old policy expires, you are granted a 30-day grace period to complete the transition. During this time, you are still considered "continuously covered" for the purpose of maintaining your waiting period credits, provided you do not let the policy lapse beyond this window.
  
• Mandatory Coverage for Severe Conditions:
  As of the 2025-26 guidelines, insurers can no longer issue a "flat rejection" for portability based on severe pre-existing conditions like Cancer, Heart Disease, or HIV/AIDS. While they can still apply medical underwriting (loading premiums or specific permanent exclusions), they must offer a product option rather than an outright denial of the port.
  
• Standardized Moratorium Transfer:
  The "Moratorium Period" (now reduced to 5 years) is explicitly recognized as a portable credit. If you have already completed 5 years with Insurer A, the new policy at Insurer B begins with the moratorium already satisfied, meaning they cannot contest claims for non-disclosure except in cases of proven fraud.
  

You must apply at least 45 days before renewal.

Update: While 45 days is the recommended standard for safety, the current IRDAI window allows applications between 30 to 60 days prior to the renewal date. Some insurers may choose to accept requests even later at their discretion, but the statutory right is protected from the 30-day mark.
