Short answer: For health insurance portability vs migration, first identify whether the insurer changes. Migration moves recognised credits to another health policy with the same insurer; portability moves them to another insurer. Neither label means that an application is already accepted or that the replacement contract has identical benefits. Start with the renewal date, obtain the correct application route and ask for written confirmation of the cover and credits actually recognised.
This guide is for Indian readers considering a change to an indemnity health policy. It explains how to prepare and compare the two routes, rather than calculate a treatment’s waiting-period completion date. It is an evergreen explanation checked on 25 October 2026, not an announcement of a new rule or an assessment of any person’s medical eligibility.
Health insurance portability vs migration: choose the route
IRDAI’s health-insurance FAQs distinguish migration with the same insurer from portability between insurers. The distinction concerns the insurance company taking the risk, not simply the app, agent, employer or payment channel through which you obtained the cover. Check the insurer’s legal name in the existing schedule and the proposed replacement documents.
If two products use similar branding, do not infer that they belong to the same insurer. Conversely, a redesigned customer portal does not establish that the insurer has changed. Ask the insurer which route it will process and what documents that route requires. Record the answer beside the product names so you can compare like with like.
For employer or other group cover, identify the master policy and your membership certificate before asking about a move. Explain whether you are leaving the group, changing a personal policy or seeking cover for family members. Those facts should reach the insurer; a generic request to “transfer my insurance” can leave the actual transaction unclear.
Work backwards from the actual renewal date
The current FAQ’s normal portability window is at least 30 days before renewal, but no earlier than 60 days before it. It also describes insurer discretion to consider a late proposal while ensuring no break in cover. Treat that discretion as something to confirm, not a reason to wait until the existing policy is about to expire.
Put the renewal date from the issued schedule into your planning notes. Then identify the dates by which you want to compare terms, resolve missing history and receive a decision. These are your preparation targets; they are not a substitute for an insurer’s official application requirements or a promise of completion by your preferred date.
If renewal is already close, contact both the existing and proposed insurer through their official channels. Ask what can actually be processed and how continuity will be protected. Do not assume that submitting a form, receiving an acknowledgement or paying a proposed premium automatically extends the old contract. Obtain the applicable instruction before relying on any interim arrangement.
Prepare a policy history that another insurer can follow
Collect the present schedule, relevant previous schedules, renewal receipts, endorsements and the completed proposal information available to you. Keep a list of insured family members and any changes in that list. Where a record is missing, ask its issuer for a copy rather than creating a replacement document yourself.
Make a chronology of the cover you actually held. Separate the first commencement date, each renewal period, changes in the sum insured and changes in benefits. A payment date is useful evidence, but should not be silently substituted for a policy’s stated coverage dates. Note any gap or unclear period for the insurer to address.
Keep claim-history information accurate. A proposed insurer may need records that do not fit into a brief sales conversation. Ask how it wants supporting material supplied and send it through the legitimate route. Do not conceal an earlier claim because it was small, withdrawn or handled by a previous administrator; answer the questions actually asked.
Ask for a credit mapping, not a general assurance
IRDAI’s FAQ describes transferred credits covering the existing sum insured and relevant accumulated benefits, including no-claim bonus, specified waiting periods, pre-existing-disease waiting and moratorium credit. Ask the insurer to identify how the recognised history is recorded for the proposed contract. Do not turn that general description into your own calculation of an individual’s entitlement.
A useful comparison separates each insured person and each changed element. If the proposal asks for more cover, ask what treatment applies to the existing amount and the increased portion. If a family member is newly included, ask about that person’s terms separately. The insurer’s answer should make these distinctions visible rather than applying one reassuring anniversary to everything.
Keep evidence of the recognised credit with the new schedule and endorsements. If a sales message says all credits are retained but the issued pack does not explain them, ask for clarification through the insurer’s servicing channel. You need a record that can be understood later, not merely an encouraging phrase during purchase.
Compare the replacement contract before deciding
Preserving a credit is one part of a switch. Read the proposed policy wording and Customer Information Sheet for the actual benefits, exclusions, limits and conditions. A similar product name or sum insured does not establish that the two contracts respond to the same hospital bill in the same way.
| Comparison item | Question to resolve |
|---|---|
| Benefits and limits | Which relevant benefits are included and what limits apply? |
| Cost sharing | What deductible, co-payment or other contribution remains yours? |
| Continuity | Which prior-cover credits are recognised, and where are they recorded? |
| Service arrangements | What current network or service information matters to your circumstances? |
| Price | What is the complete quoted premium for the stated people and cover? |
Mark an unresolved answer as unresolved. Do not fill a comparison sheet with assumptions simply to rank products. For example, if a hospital matters to you, check current official network information and ask about the relevant service process. A past network list or another person’s experience may not answer the question for your proposed cover.
Keep a government health-benefit entitlement separate from a private-policy transfer. Our Ayushman Bharat guide for people aged 70 and above explains a different route. Its eligibility or card process should not be used as evidence that a private insurer has accepted a migration or portability proposal.
Submit the proposal through the correct insurer channel
For portability, the FAQ describes a portability form and proposal form supplied to the acquiring insurer, with policy and claim information exchanged between insurers through the Insurance Information Bureau route. Do not confuse a comparison website enquiry with the completed insurer application. Ask which reference identifies the actual proposal being considered.
Review the completed answers before authorising them. Check names, dates, existing cover and requested changes against your records. If an intermediary helps, retain the version sent to the insurer and any later correction. Do not approve a blank form or accept an instruction to omit information that the proposal asks you to disclose.
Keep the acknowledgement, document requests and replies together. Respond to a request by addressing the item actually missing, rather than repeatedly sending an unlabelled folder. A short covering note identifying the proposal and the attached records makes the file easier to follow without inventing a faster processing entitlement.
Read the decision and protect the handover
IRDAI’s FAQ states an existing-insurer data response of 72 hours and an acquiring-insurer decision within five days after it receives that information. These are different stages. Do not add them to an arbitrary enquiry date and promise yourself a final policy by the resulting day. Identify the stage and the actual acknowledgement when following up.
Before relying on the new arrangement, check whether you have an acceptance, a request for information, a revised offer or a refusal. Read any conditions attached to the response. A quote is not the same document as an issued schedule, and an application reference does not by itself establish the start of replacement coverage.
Ask for the intended start and end boundaries of the two contracts and confirm the steps required from you. Avoid ending existing cover on the assumption that another insurer will accept you. If the timing becomes uncertain, obtain a written explanation of the available route; this article cannot choose an individual renewal or medical-risk decision.
Example: a family comparing two different changes
Consider a fictional family reviewing an approaching renewal. One option is another product from its present insurer; the other is a policy from a different insurer. The family identifies the first as a migration enquiry and the second as portability, then asks each insurer for the relevant process and document list.
They prepare the same accurate history for both, while recording the requested sum insured and family-member changes separately. They compare terms, seek written credit recognition and wait for the actual decisions before treating either option as replacement cover. The example illustrates a preparation method; it does not predict acceptance, pricing or claim payment.
Frequently asked questions
Does changing an agent mean portability?
Not necessarily. Identify whether the insurer changes and ask which policy transaction is being processed. The sales channel alone does not settle that question.
Will all new benefits automatically inherit old credits?
Do not assume that. Ask the insurer to map the recognised history to the proposed people, cover amounts and benefits, particularly where anything has changed.
Can a late request be treated as guaranteed acceptance?
No. Confirm the actual insurer decision and continuity arrangement. A discretionary late-processing route is not an acceptance promise.
Is there one new calendar deadline for everyone?
No. This guide uses the policy’s own renewal date and existing process guidance. No deadline-tracker entry is proposed.
Final health insurance portability vs migration checklist
Identify the insurer and route, plan from renewal, collect an accurate history, compare the proposed contract and obtain a clear decision with recognised credits and coverage dates. A careful health insurance portability vs migration comparison should leave you with verifiable documents and specific unanswered questions, not an assumed seamless switch.
