Many policyholders assume that health insurance portability is a simple administrative process. They decide to switch insurers just a few days before renewal, believing that paying the premium guarantees uninterrupted coverage.

Unfortunately, that is not how health insurance portability works. Every year, policyholders lose valuable health insurance protection because they initiate portability too late, misunderstand the underwriting process or assume the new insurer is obligated to accept their proposal.

When it comes to health insurance, timing matters just as much as choosing the right policy.

What Happens During Health Insurance Portability?
Portability allows you to transfer your existing health insurance policy from one insurer to another while preserving eligible continuity benefits, subject to applicable regulations and underwriting. However, portability is not an automatic transfer.

Before accepting your proposal, the new insurer may evaluate,

· Existing health insurance policy details
· Previous Claim history
· Pre-Existing Diseases (PED)
· Current medical conditions
· Proposal form disclosures
· Previous insurer’s records
· Medical Reports (If required)
· Tele-verification or additional underwriting

Only after completing its assessment will the insurer decide whether to,

· Accept the proposal
· Accept it with modified terms and conditions
· Request additional information
· Reject the proposal

Simply paying the premium does not guarantee portability approval.

Why You Should Start Portability 90-60 Days before Renewal
The portability process involves multiple parties and several verifications. Starting the process 90 days to 60 days before the renewal date gives you ample time for,

· Medical Underwriting from the new insurer
· Clarification request raised by new insurer
· Additional documentation
· Communication between insurers
· Proposal review
· Final Underwriting decision
· Policy issuance before expiry

Waiting until the final date creates unnecessary risks.

The Biggest Mistakes Policy Holders Make

a) Initiating Portability Only 3 to 4 days before Renewal
Late applications leave very little time for underwriting. If additional documents or medical reports are required, the insurer may not complete the process before your existing policy expires. What issue does this cause?

b) Starting Portability During the Grace Period
Many policyholders believe the grace period extends their insurance protection. In health insurance, it does not. While the grace period allows renewal without immediately losing continuity benefits (subject to your policy terms), in case of a hospitalization during the grace period, claim will not be covered because the policy is not active for fresh claims until the renewal is completed.

Using the grace period to initiate portability significantly increases risk.

c) Assuming Premium Payment Means Approval
Paying the premium is not the final approval. The insurer still has the right to,

· Review medical disclosures
· Conduct underwriting
· Seek additional information
· Decline the portability proposal if underwriting requirements are not satisfied

If the proposal is declined, the premium is generally refunded according to the insurer’s process, but the coverage is not automatically created simple because payment was made.

d) Increasing Health Cover during Portability
Many policyholders believe that if they increase their health insurance cover while porting their policy, the entire increased amount immediately receives the benefit of completed waiting periods. “THIS IS INCORRECT.”

Suppose your existing policy has,

· Base Sum Insured = Rs 10 Lakh
· No Claim Bonus (NCB) = Rs 3 Lakh
· Total Eligible Cover = Rs 13 Lakh
· Policy running continuously for 3 years or more

If you decide to port this policy and simultaneously increase the cover to Rs 20 lakh, here’s what actually happens

Continuity Benefit
The existing eligible cover of Rs 13 Lakh generally carries forward the continuity benefits already earned under previous policy, subject to the portability rules and the new insurer’s acceptance.

Fresh Waiting Period
The additional Rs 7 lakh enhancement is treated as fresh coverage. Therefore, the increased portion may be subject to waiting periods applicable under the new policy, such as,

· Initial waiting period of 30 Days, except for accidents
· Specific disease waiting periods (as per the policy wordings)
· Pre-Existing Diseases (PED) waiting periods, wherever applicable

The previously completed waiting period generally continue only for the eligible ported amount.

Example as follows

Why this Rules Exists?
Portability protects the benefits you have already earned. However, increasing the sum insured introduces additional insurance risk for the new insurer. Therefore, insurer generally provides continuity benefits only for the existing eligible cover, while the enhanced amount is treated as a newly insured coverage under the new policy.

Important Note
The exact continuity benefits, waiting periods, treatment of No Claim Bonus and enhancement rules vary depending on,

· The insurer’s underwriting decision
· The product being ported into
· Applicable IRDAI portability regulations
· Terms and conditions of the new health insurance policy

Always verify these details in writing before accepting the portability offers.

e) Incomplete or Incorrect Health Disclosures
Health insurance operates on the principle of utmost good faith. Failure to disclose,

· Existing illnesses
· Ongoing treatments
· Previous surgeries
· Existing medications
· Diagnostic findings

Can result in underwriting complications and future claim delays or repudiations. Always disclose honestly, even if you think a condition is minor.

Can an Insurance Agent Solve the Problem Later?
Many people assume their insurance advisor or insurance intermediary can “MANAGE” the situation if portability gets delayed. In reality, once underwriting timelines are missed or documentation remains incomplete, even the best intermediary cannot force an insurer to approve portability.

Insurance companies make underwriting decisions based on,

· Medical evidence
· Regulatory guidelines
· Internal underwriting policies
· Proposal disclosures

Not on verbal assurances.

What if a Medical Emergency Happens During Portability?
This is where many policyholders unknowingly gamble with their family’s financial security. Imagine this situation,

· Existing policy renewal is approaching
· You apply for portability at the last moment
· The new insurer is still reviewing your proposal
· A hospitalization occurs before the new policy is issued

If a claim arises during the grace period, your existing insurer may reject the claim, the new insurer may deny insurance portability, and would request you to re-apply 3 to 4 month later.

The insurer can reject the proposal outright and will refund the premium. No coverage guaranteed and you will lose your old policy.

A Simple Portability Checklist
Before switching your health insurer,

· Start portability 90 to 60 days before renewal
· Keep all communications over email
· Disclose every medical condition honestly
· Respond quickly to underwriting queries
· Keep previous policy documents ready
· Maintain claim history records
· Track proposal status until the new policy is issued
· Do not wait for the grace period

Final Thoughts
Health insurance portability is a valuation facility, but only when used correctly. The biggest mistake is assuming that portability is automatic. It is not. It is a regulated underwriting process where timelines, disclosures, medical history and insurer assessment all play an important role. Insurance is designed to protect you during medical emergencies. Not create uncertainty because of avoidable delays.

Plan early, disclose honestly. Complete the process before renewal, because in health insurance, timing can be just as important as coverage.
