Health Insurance Portability Rejected or Delayed? How to Fix It (2026)
By Hari Kotian (IRDAI Cert. Advisor, 25+ years) | Published on 2026-09-27
Portability is your right under IRDAI's health insurance regulations — but in practice, insurers make you earn it twice: once through the paperwork, and again through underwriting that treats your claims history as a debt. The single most damaging mistake I see is timing: people discover the 45-day rule when 20 days are left. Here is how the process actually works, and what to do when it goes wrong.
The porting clock: deadlines that decide everything
| Deadline | What happens |
|---|---|
| 45–60 days before renewal | Apply to the new insurer on the portability form. Late applications are the #1 self-inflicted failure. |
| Within 7 days of applying | The new insurer requests your claims/underwriting data from the old one via IIB. You fill the detail form once. |
| 15 days from data receipt | New insurer must decide. No decision in time = port treated as accepted under IRDAI portability norms. |
| Renewal date | If porting, do NOT let the old policy lapse — pay if needed. A lapsed policy kills the credit you are porting. |
Why port requests get rejected or priced punitively
- Claims-heavy history — the new insurer sees 5 years of usage and loads the premium 15–50% or excludes the treated condition entirely.
- Chronic condition now declared — diabetes/hypertension diagnosed during the old policy surfaces in underwriting and attracts exclusions at the new one.
- Data gaps — the old insurer's data transmission is incomplete, and the new insurer prices the void conservatively.
- Low sum insured migrating to high — a ₹5 lakh policy porting to ₹50 lakh triggers full fresh underwriting on the increment.
- Missed deadlines — applying at 20 days leaves no room for the data round-trip, and the clock kills the port, not the insurer.
The fix: a rejection is often a negotiation, not a verdict
- Get the reason in writing. "Underwriting decline" is not a reason. Ask which factor — claims, condition, sum insured, or timing — drove it.
- Attack the data, not the decision. If the decision rests on wrong claims data (wrong dates, duplicated entries, closed claims shown open), file a data-correction request through the old insurer and re-apply.
- Negotiate the loading. Loadings are offers, not laws. A documented remission history, current normal reports, or a higher voluntary deductible moves them. I have seen 30% loadings halved on paper evidence.
- Parallel-apply. Apply to two insurers for the same renewal — porting is not exclusive until one accepts. Compare the acceptance letters, including exclusions, line by line.
- Never let the old policy lapse while negotiating. If the port fails this year, renewal preserves continuity for next year's attempt.
When to escalate
If the old insurer refuses to transmit your data, or the new insurer ignores the 15-day decision window and then denies, put the sequence in writing: grievance email to both insurers' GROs citing the IRDAI portability timelines, then Bima Bharosa and the Insurance Ombudsman if unresolved in 30 days. Keep every acknowledgement. Portability complaints are among the few categories where the paper trail alone often settles the matter.
Frequently Asked Questions
When should I apply for health insurance portability?
Apply at least 45 days before renewal, and ideally 60. The new insurer must decide within 15 days of receiving your complete portability data from the old insurer; if it delays beyond that window, IRDAI rules treat the port as accepted.
Can the new insurer reject my portability request?
It can reject on underwriting grounds just like a fresh proposal — unfavourable claims history, undisclosed conditions, or age limits. What it cannot do is deny you the credit you earned: waiting periods already served and continuity for pre-existing diseases carry over when the port is accepted.
Why is porting harder than insurers admit?
Portability data flows between insurers through the Insurance Information Bureau. Claims in the last 5 years are visible to the new insurer, and heavy usage or chronic-condition claims often attract loadings of 15–50% or partial exclusions. Rejection usually means the new insurer priced you as a fresh risk rather than a port.
What if no insurer accepts my port request?
First, check the rejection reason in writing. If the current policy is still active, renew it — losing continuity is the worst outcome. Then re-apply to other insurers for the next renewal with better documentation of your claims record. If a rejection appears arbitrary, a written grievance to the insurer and then IRDAI Bima Bharosa is the escalation path.
Does porting move my waiting-period credit for pre-existing diseases?
Yes. When a port is accepted, the time already served on waiting periods for pre-existing conditions and specific treatments counts at the new insurer. This credit is the entire point of portability — get the acceptance letter to state it explicitly.
