Health insurance portability: how to switch insurers without losing your waiting period benefits

Unhappy with your health insurer? IRDAI rules let you port to a new one while keeping your pre-existing disease waiting period credits — so you don't restart from scratch. The catch: you must apply 45–60 days before renewal, and acceptance isn't guaranteed. Never cancel the old policy until the new one is confirmed.

For informational purposes only. Health insurance portability is governed by IRDAI regulations. Terms vary by insurer. Read the policy document and consult an IRDAI-registered advisor before switching.

If you are unhappy with your health insurer — poor claim experience, rising premiums, limited network hospitals — you are not stuck. IRDAI rules allow you to port your health insurance policy to a different insurer while keeping the benefits you have already earned, most importantly your pre-existing disease (PED) waiting period credits. Done right, portability lets you switch without starting your waiting periods from scratch.

What portability preserves

The most valuable thing portability protects is your accumulated waiting period credit.

When you buy a new health policy, pre-existing conditions are typically subject to a waiting period of 1–4 years before they are covered. If you have already served, say, 3 years of that waiting period with your current insurer, portability carries that credit to the new insurer — so you do not restart the waiting period.

Portability preserves:

Pre-existing disease (PED) waiting period already served
Specific-disease waiting periods already served
The continuity of coverage (no gap)
In many cases, accumulated no-claim bonus (within limits)

Without portability — if you simply cancel and buy a fresh policy — you would lose all this and start every waiting period again.

What you can port

Under IRDAI's portability regulations, you can port:

From one insurer to another (e.g., switching companies)
From one plan to another within the same insurer
Individual and family floater policies
Group health insurance to an individual policy (in many cases, e.g., when leaving a job — subject to the insurer's terms)

Portability applies to indemnity-based health insurance. It does not apply to personal accident or travel policies.

The timing: when to initiate portability

This is the most common point of failure. Portability must be initiated before your current policy's renewal date — specifically, you must apply to the new insurer at least 45 days before your existing policy expires (and not more than 60 days before, in most cases).

If you miss this window, you may have to wait until the next renewal cycle, or risk a gap in coverage that breaks continuity.

◇ Quick check: Note your policy renewal date. Mark a reminder for ~50 days before it. That is your window to initiate portability if you want to switch insurers for the upcoming policy year.

The step-by-step process

Step 1: Choose the new insurer and plan.

Compare plans on the parameters that matter (room rent limits, co-payment, no-claim bonus, network hospitals, claim settlement ratio).

Step 2: Apply for portability 45–60 days before renewal.

Submit the portability form and your existing policy details to the new insurer. The new insurer requests your history from the existing insurer through the IRDAI portability portal.

Step 3: Underwriting by the new insurer.

The new insurer reviews your history (claims, health conditions) and decides whether to accept the port. They may accept, accept with conditions, or decline. Acceptance is not guaranteed — the new insurer underwrites you afresh, though they must consider your accumulated waiting period credits.

Step 4: Decision within the regulated timeline.

The new insurer must communicate acceptance or rejection within 15 days of receiving your application and history. If they do not respond in time, they may be obligated to accept the port.

Step 5: Pay premium and get the new policy.

On acceptance, pay the premium and receive the new policy with your waiting period credits carried over.

What portability does NOT guarantee

1. Acceptance is not automatic.

The new insurer underwrites your application. If you have significant health conditions or a heavy claims history, they may decline or impose conditions. Portability gives you the right to apply with continuity, not a guarantee of acceptance.

2. Premiums may differ.

The new insurer's premium for your age and sum insured may be higher or lower than your current one. Portability preserves waiting credits, not your premium.

3. Higher sum insured may have fresh waiting on the increased portion.

If you port and increase your sum insured (e.g., from ₹5 lakh to ₹10 lakh), the waiting period credit applies to the original ₹5 lakh; the additional ₹5 lakh may be treated as fresh cover with its own waiting period.

⚠ Common mistake: cancelling the old policy before the new one is confirmed

Never cancel or let your existing policy lapse before the new insurer has confirmed acceptance and issued the new policy. A gap in coverage breaks continuity — you lose your accumulated waiting period credits and may face a period with no cover. Keep the old policy active until the port is fully confirmed.

When portability is worth it

Worth considering if:

Your current insurer has a poor claim settlement record or bad service
Premiums have risen sharply relative to comparable plans
You want better features (no room rent limit, restoration benefit, higher NCB)
Your network hospitals have changed or are inadequate

Maybe not worth it if:

You are satisfied with your current insurer's service and claims
You have significant health conditions that make a new insurer likely to decline or impose conditions
The premium difference is small and the new plan is not meaningfully better

Bottom line

Health insurance portability lets you switch insurers while keeping your pre-existing disease waiting period credits and continuity
Initiate the port 45–60 days before your current policy's renewal date — missing this window is the most common failure
The new insurer underwrites you afresh; acceptance is not guaranteed, and premiums may differ
Waiting period credit applies to your existing sum insured; an increased sum insured may carry fresh waiting on the top-up portion
Never cancel the old policy until the new one is confirmed — a coverage gap forfeits your accumulated benefits

Frequently asked questions

Q: Will I lose my no-claim bonus if I port?

A: In many cases, accumulated no-claim bonus is carried over during portability — the new insurer adds it to your sum insured as per their rules. Confirm the specific treatment with the new insurer, as NCB carry-forward terms can vary.

Q: Can the new insurer reject my portability request?

A: Yes. The new insurer underwrites your application and can decline based on your health history or claims record. Portability gives you the right to apply with continuity of benefits, but acceptance is at the insurer's discretion within IRDAI's framework. Apply well before renewal so you have time to stay with your current insurer if the port is declined.

Q: I am leaving my job. Can I port my employer group health cover to an individual policy?

A: In many cases, yes. IRDAI allows porting from a group policy to an individual policy, typically with the same insurer, often when you leave employment. This preserves your waiting period credits — valuable if you have pre-existing conditions. Ask your group insurer about the continuation/portability option before you leave the job, not after.

Q: Does portability cost anything?

A: There is no separate fee for portability itself. You pay the new insurer's premium for the policy. The process of porting (form submission, history transfer) is free under IRDAI rules.
