Health Insurance Waiting Periods and Sub-limits, Explained

Understand health-policy waiting periods, co-payments, room-rent limits, exclusions and sub-limits through a practical hypothetical claim illustration.

There are many terms within health insurance that can cause confusion when trying to understand what has been paid for your hospital bill. Wait periods, co-payments and sub-limits are three key terms that often get confused with each other. However, each term has its own purpose. Wait periods are there to limit cover for a specified period of time or condition. Co-payments allow you to claim a percentage of a claim that falls within the policy. Sub-limits are there to limit the pay-out for a specific cost or treatment. As these can be used in conjunction with one another, it is best to read the whole schedule to see what benefits you have.

Wait Periods

Many health insurance policies will have an initial wait period. The length of this will vary between policies, however, it will state what happens during the initial waiting period. Depending on the policy, it may state that any claims made within the initial wait period will be handled differently.

The initial wait period should not be confused with the start date. A policy can be in place but still have limited claims. If you are taking out insurance close to when you want to have a procedure, just because you have a policy doesn’t mean you can claim for any medical costs.

Specific Disease/Procedure Wait Periods

Within your policy there may be a list of specific diseases, treatments or procedures that will only be covered from the date stated. There will be a variety of things listed and how they are described. This may not be fully covered by the wording in the brochure, please refer to the policy wording and customer information sheet. If your diagnosis has many names or complications relating to it, please ask your insurer for clarification.

These can affect decisions, but shouldn’t be used as an excuse to not receive medical treatment. If you need medical treatment you shouldn’t put it off due to a general explanation. Please ask your insurer to clarify what is covered within your policy. The medical professionals will decide what treatment you should receive.

Pre-existing Disease

Pre-existing disease refers to conditions set out in the policy and regulations. Please ensure you know what conditions are included, how long the look back period is and how long the wait period is. This will be set out within the policy. When applying please be honest with your medical history. If you have a condition that is managed by medication it can still be relevant to the application. Don’t assume it’s not relevant just because you don’t think it is.

[Please verify current IRDAI wording on pre-existing and specific disease maximum wait periods within the health insurance regulations.] If there are any changes to the rules please update this article with the official notification and the date it comes in to effect.

Co-payment

Co-payment means that you will pay a specific percentage or proportion of the claimable costs. A deductible may be included in the policy that will mean you have to pay a set amount before the policy will pay. The co-payment can be a percentage of the whole claimable costs or may only apply to certain situations. Please refer to the exact wording within the policy.

For example, if you had a hospital bill with £80,000 of claimable costs and the policy had a 10% co-payment this would equate to £8,000. You would then have £72,000 of claimable costs. This is not an accurate calculation as there may be some items that aren’t claimable or have a limit. This is just an example.

Room Rent Limit

A room rent limit will limit what room you can stay in or how much you can claim. This may be a limit on how much you can claim in rupees, a percentage of the sum insured or something else. If the policy states that other hospital costs are linked to the room you are allowed to stay in, you may find that choosing a more expensive room affects more than the room cost. Please refer to the policy wording to see how this is calculated. Not all insurers will have the same proportional deduction.

Before being admitted to hospital please ask what would happen if you are offered a room outside of the allowed room? What would be reduced and by how much? This may depend on the policy, hospital charges and how the insurer sees it. Just because the hospital can guarantee you a room doesn’t mean you will be able to claim for the room.

Sub-limits & Exclusions

A sub-limit means there is a maximum amount you can claim for a specific cost or treatment. An exclusion means that you may not be able to claim for the item at all. Both can be present in the policy. Please check the summary to see what applies.

Check what specific procedures, ambulance, consumables, non-medical items and outpatient treatments are included. The policy will vary. Are there any limits? Is it per claim, per year, per procedure or is there another condition? The name will not tell you how it interacts with other clauses.

Example

Say you have a hospital bill of £150,000 (this is purely an example). £20,000 of the items are excluded. You now have £130,000 to consider. There may be a sub-limit on a specific procedure. There may also be a room rent clause. There may then be a 10% co-payment applied to the remaining claimable amount. The insurer will have calculated this based on the policy wording. You will not be able to replicate what they have done as each clause will need applying in the order set out in the policy.

This example shows that just because a policy states they will cover £5lakh it does not mean they will pay the full £1.5lakh. The sum insured is just part of the policy. To calculate a real claim you would need to look at the policy schedule, wording, hospital invoices and what the insurer has decided.

How to compare the terms

Within the policy schedule and customer information sheet please note down what the initial wait period, specific disease wait periods, pre-existing condition clause, co-payment, deductible, room eligibility, sub-limits and exclusions are. Compare like for like. A lower premium may have cost sharing or less limits. There is no one factor that will give you the full value of the policy.

Don’t assume everything is covered. Please ask for the clause and note this down. If the insurer is not clear please ask them for clarification via their official customer channel. The policy wording and current regulations should help.

Common Misconceptions

A wait period does not mean the whole policy isn’t in place. A co-payment isn’t the same as a deductible. A room rent limit may affect other costs if the policy states it. Having a high sum insured won’t remove exclusions or sub-limits. It is good to understand these differences ahead of any hospital event as you may not have time to read through them all in detail due to the stress.

Conclusion

Wait periods, co-payments and sub-limits are all separate features that can affect your claim. How they affect you will depend on the exact wording and current regulations. Use examples to understand how they work numerically. The policy schedule, official IRDAI information and asking for clarification in writing will help.

Understanding Denials/Deductions

If you haven’t received as much as you were expecting please ask for a breakdown of the calculations. Please ask what clause was used for each deduction. Split up the exclusions, co-payment, deductible, room adjustment and any sub-limits. These aren’t interchangeable terms and may all affect the same bill. Having this in writing will help you see where the difference is.

If you are still unsure please use the insurer’s formal complaints process. Keep copies of your bill, claim form, pre-authorisation request, settlement statement and any correspondence. Refer to the current IRDAI information on policyholder complaints to ensure you escalate correctly. We cannot decide whether a real claim should be paid based on this article. You need to refer to the contract and facts.

Keeping Summaries Up To Date

Whenever an insurer issues an endorsement or renewal please save it with the original policy wording. If you just save a summary, it may not reflect the new wording. If you have multiple policies within your family please label them with the name of the insured, dates and insurer. This will help avoid using incorrect wording when making a claim.

What to ask before the policy starts

Ask the insurer what the start date is, when each waiting period ends and whether the condition is a pre-existing, specific or excluded condition. Ask what the reference to the clause is within the policy wording. If you only receive a verbal answer please ask for clarification via their official customer channel. If you can get a clear answer before you take out the policy it will be easier to understand.

When comparing two contracts please write down the details. Don’t just assume a policy has a short waiting period or no room limit. Check what exclusions, co-payments and any other limitations there are. The current regulations and wording will determine what the situation really is. Please check the wording again if the policy is renewed or changed.
