Health Insurance Portability in India: What It Is, How It Works & IRDAI Rules

If your health insurer has poor claim settlement, rising premiums, or a shrinking hospital network, you should be able to leave without penalty. Health insurance portability, introduced by IRDAI, gives you exactly this right — the ability to switch insurers while retaining the credit for waiting periods you have already served. This guide explains the rules, the process, and the key decisions to make when considering porting.

What Health Insurance Portability Means

When you buy a health insurance policy with a pre-existing condition, you typically face a waiting period — anywhere from 2 to 4 years — before that condition is covered. This waiting period was historically a lock-in mechanism that trapped policyholders with poor insurers: leaving meant restarting the waiting period from zero with a new insurer.

IRDAI’s portability rules change this. Under portability:

• Waiting period credits transfer — time already served is recognised by the new insurer
• No Claim Bonus may transfer — accumulated bonus (sum insured increase from claim-free years) can be carried forward
• Continuity of coverage — no gap in coverage during the transition

What portability does NOT mean:

• You do not automatically get the same premium with the new insurer
• Not all accumulated benefits carry forward in all cases
• The new insurer can set its own premium based on your current age and health profile

IRDAI Rules for Health Insurance Portability

IRDAI has established specific, mandatory rules that all insurers must follow:

What Transfers When You Port

Definitely Transfers (IRDAI Mandated)

• Pre-existing disease waiting period credit — If you have served 2 years of a 3-year waiting period, only 1 year remains with the new insurer
• Disease-specific waiting period credit — e.g., a 1-year waiting period for hernia that you have already served is credited
• Continuity of coverage — You have no gap in health coverage between old and new policy

Usually Transfers (Insurer-Dependent)

• No Claim Bonus — Most insurers recognise accumulated NCB, but the form it takes may differ (sum insured increase or premium reduction)
• Coverage terms — For the same sum insured, you should expect equivalent coverage to your previous policy

Does NOT Automatically Transfer

• Premium rate — New insurer re-prices based on your current age and health; you may pay more or less depending on the comparison
• Policy terms and features — New plan benefits, sub-limits, and add-ons are governed by the new insurer’s product
• Additional sum insured beyond original — Fresh waiting periods apply on any incremental sum insured

Step-by-Step: How to Port Your Health Insurance Policy

Step 1: Decide approximately 60 days before renewal

Research insurance options at least 60 days before your policy renewal. This gives you buffer time beyond the 45-day minimum requirement.

Step 2: Compare new plans

Evaluate:

• Network hospital coverage in your city
• Sum insured options and premiums
• Sub-limits (room rent caps, disease-specific limits)
• Claims processing — in-house or TPA?
• Claim settlement ratio (available in IRDAI’s annual report)
• Restoration benefit, NCB structure, and other features

Step 3: Submit portability request to the new insurer

Fill in the new insurer’s portability form (or apply online) at least 45 days before renewal. Provide:

• Current policy details and documents
• Claim history (last 3–5 years)
• Medical history disclosure
• Identity and age proof

Step 4: Previous insurer shares your history

Within 7 working days of the new insurer’s request, your current insurer must share:

• Your claim history
• Medical records on file
• Policy schedule and endorsements

Step 5: New insurer evaluates and responds

The new insurer reviews your health profile. They will:

• Accept at standard terms
• Accept with loading (higher premium)
• Accept with specific exclusions
• Reject the application (allowed if your risk profile is too high)

If rejected: You renew with your current insurer and can try porting again at the next renewal.

Step 6: Pay premium and receive new policy

If accepted, pay the first-year premium to the new insurer. Your new policy begins from the day your old policy lapses. There should be no gap.

Valid Reasons to Port Your Health Insurance

1. Poor Claim Settlement Experience

If you have experienced unjustified claim rejections, long pre-authorisation delays, or poor post-claim support, porting is fully justified. A high claim settlement ratio and strong in-house claims team should weigh heavily in choosing the new insurer.

2. Premium Has Increased Significantly

Insurers revise premiums on renewal. If your premium has jumped substantially and a competitor offers equivalent cover at a lower price, porting makes financial sense.

3. Coverage Gaps

Your health needs may have evolved — you now need maternity cover, mental health coverage, or OPD benefits your current plan doesn’t offer.

4. Sub-limit Restrictions

If your current policy has restrictive sub-limits (room rent cap, disease-specific limits) that have caused or could cause under-payment in claims, porting to a plan without sub-limits is rational.

5. Hospital Network Doesn’t Cover Your Preferred Hospitals

If the insurer’s cashless network doesn’t include hospitals you use or trust, porting to an insurer with better network coverage in your area is valid.

6. Leaving an Employer / Group Plan

When you change jobs, your employer’s group mediclaim lapses. Porting to an individual policy before leaving ensures:

• Waiting period credits from the group policy carry forward
• You are not left uninsured
• Pre-existing conditions covered in the group plan continue without a fresh waiting period

Reasons NOT to Port (When Staying Is Better)

You Are Near the End of a Waiting Period

If you have served 3 years of a 4-year waiting period for a pre-existing condition, porting and restarting is costly in coverage terms. Wait until the waiting period is fully completed, then port if you still want to.

You Have a Complex Pre-Existing Condition

Insurers can accept portability with exclusions for high-risk conditions. A new insurer might explicitly exclude a condition that your current insurer already covers. Get the exact terms in writing before porting.

You Have a Pending or Recent Major Claim

If you have a recent large claim, some insurers may reject your portability application or add heavy premium loading. Porting immediately after a major claim may not be feasible.

Your Current Insurer Has Good Track Record

If your claim experiences have been smooth, premiums are reasonable, and coverage is adequate — there is no need to port. Loyalty is not irrational when the incumbent insurer performs well.

Portability vs Switching: What’s the Difference?

Porting = switching insurer with waiting period credit transfer (the subject of this page)

Switching/fresh policy = cancelling existing policy and buying a new one from scratch. This means all waiting periods restart from zero, and any pre-existing condition waiting periods served under the old policy are forfeited.

Do not cancel your existing policy and then buy from a new insurer. Always use the formal portability mechanism to carry your waiting period benefits.

Migration from Group Policy to Individual Policy

When leaving employment, you can migrate from a group health policy to an individual policy under IRDAI guidelines. Key rules:

• You must apply for the individual policy within 30 days of your group policy lapsing
• The individual insurer must credit your waiting period served under the group policy
• The sum insured of the individual policy should be at least the same as under the group policy for full waiting period credit
• This is particularly important for employees who have served the waiting period for pre-existing conditions under their employer’s group plan and want continuous coverage

Documents Required for Portability

• Copy of current health insurance policy document
• Latest premium payment receipt
• Claim history / certificate of insurance from current insurer (insurers provide this on request)
• Medical records relevant to any pre-existing conditions
• Identity proof (Aadhaar/PAN/Passport)
• Age proof
• Address proof
• Completed portability request / proposal form from the new insurer

What to Do If Your Portability Request Is Rejected

1. Ask for the reason in writing — the new insurer must provide documented reasons
2. Check if you can challenge exclusions — if they are wrongly citing a condition as pre-existing, you can dispute with evidence
3. Escalate to the new insurer’s grievance redressal team
4. File a complaint with IRDAI via the Bima Bharosa portal (bimabharosa.irdai.gov.in) if you believe the rejection violated IRDAI guidelines
5. Try another insurer — rejection by one does not prevent you from applying to another insurer for portability at the same renewal cycle
