The ABC’s Of Health Insurance: Simplifying Frequently Used Terms In Your Policy Document

Health insurance documents often contain technical words that can be difficult to understand. Terms such as deductible, co-payment, waiting period, sum insured and cashless hospitalisation may create confusion, especially when you are comparing policies for the first time.

Understanding these common health insurance terms can help you compare plans, estimate your out-of-pocket expenses and avoid unexpected problems while making a claim.

Common Health Insurance Terms and Their Meanings

Add-On Cover or Rider

An add-on cover, also known as a rider, is an optional benefit that can be added to a basic health insurance policy by paying an additional premium.

Common add-ons may include:

• Critical illness coverage
• Personal accident coverage
• Maternity benefits
• Hospital cash benefit
• OPD coverage
• Room-rent waiver

The availability and conditions of riders differ between policies.

Ambulance Cover

Ambulance cover pays eligible expenses incurred for transporting an insured person to a hospital during a medical emergency.

Some policies provide ambulance coverage up to a specified limit for each hospitalisation or policy year. Air ambulance services may require separate coverage.

AYUSH Treatments

AYUSH refers to Ayurveda, Yoga and Naturopathy, Unani, Siddha and Homoeopathy.

Many health insurance policies cover eligible AYUSH treatment when it is received at a recognised hospital or healthcare centre. Coverage remains subject to the policy’s limits, exclusions and documentation requirements.

Beneficiary

A beneficiary is the person who is entitled to receive a benefit under an insurance policy.

The beneficiary may be the insured person, nominee or another eligible individual, depending on the policy and the type of benefit involved.

Cashless Hospitalisation

Cashless hospitalisation allows an insured person to receive eligible treatment at a network hospital without paying the entire approved hospital bill upfront.

The hospital sends a pre-authorisation request to the insurer or third-party administrator. After approval, the insurer settles eligible expenses directly with the hospital.

The policyholder may still need to pay for:

• Deductibles
• Co-payments
• Non-medical items
• Expenses exceeding policy limits
• Excluded treatments
• Unapproved charges

Claim

A health insurance claim is a formal request made to an insurer for payment of eligible medical expenses.

Claims are generally settled through one of the following methods:

• Cashless claim: The insurer settles approved expenses directly with a network hospital.
• Reimbursement claim: The policyholder pays the hospital bill and later submits documents to the insurer for reimbursement.

Medical bills, prescriptions, diagnostic reports, discharge summaries and completed claim forms may be required.

Co-Payment

A co-payment is the portion of an approved claim that must be paid by the policyholder.

For example, if a policy has a 20% co-payment and the approved claim amount is ₹1 lakh, the policyholder may have to pay ₹20,000 while the insurer pays the remaining eligible amount.

Co-payment conditions may apply based on age, treatment, hospital type or location.

Critical Illness

A critical illness is a serious medical condition specifically listed in the insurance policy. Examples may include certain types of cancer, heart attack, stroke, kidney failure and major organ transplant.

A condition is covered only when it meets the exact definition and severity requirements stated in the policy.

Critical Illness Insurance

Critical illness insurance usually provides a fixed lump-sum benefit when the insured person is diagnosed with a covered critical illness and satisfies the policy conditions.

The payment is generally based on the selected sum insured rather than the actual hospital bill. The amount may be used for treatment, household expenses, loan payments or loss of income.

Daily Hospital Cash

Daily hospital cash is a benefit that provides a fixed amount for every eligible day the insured person remains hospitalised.

It can help manage expenses that may not be covered by a regular health insurance policy, such as transportation, food for attendants or loss of income.

Day-Care Treatment

A day-care treatment is a medical procedure that can be completed in less than 24 hours because of advanced medical technology.

Examples may include:

• Dialysis
• Chemotherapy
• Cataract surgery
• Radiotherapy
• Certain minor surgeries

Not every treatment lasting less than 24 hours qualifies as a covered day-care procedure. The procedure must satisfy the conditions mentioned in the policy.

Deductible

A deductible is the amount that must be paid by the policyholder or covered through another health insurance policy before the insurer becomes liable to pay.

For example, if a policy has a deductible of ₹50,000 and an eligible claim is ₹2 lakh, the insurer may cover the approved amount above ₹50,000, subject to other policy conditions.

Deductibles are commonly found in top-up and super top-up health insurance plans.

Exclusion

An exclusion is a medical condition, treatment, expense or situation that is not covered by the policy.

Common exclusions may include:

• Cosmetic procedures that are not medically necessary
• Non-medical hospital items
• Experimental or unproven treatments
• Claims arising from intentional self-harm
• Treatment during an applicable waiting period
• Expenses exceeding specified sub-limits

Exclusions differ between policies and should always be reviewed before purchasing coverage.

Family Floater Policy

A family floater health insurance policy covers multiple family members under one shared sum insured.

Depending on the insurer, a family floater may include:

• Policyholder
• Spouse
• Dependent children
• Parents
• Parents-in-law

Because all insured members share the same coverage amount, the selected sum insured should be sufficient for the entire family.

Free-Look Period

The free-look period allows a policyholder to review a newly purchased health insurance policy and cancel it if the terms are unsuitable.

If the policy is cancelled during this period, the insurer may issue a refund after deducting applicable expenses such as medical examination costs, stamp duty and coverage charges for the days during which the policy was active.

The applicable duration and cancellation conditions should be checked in the policy document.

Grace Period

The grace period is the additional time provided by an insurer to renew a policy after its premium due date.

Renewing within the grace period may help preserve continuity benefits. However, coverage for medical expenses incurred during the gap may not be available, depending on the policy terms.

Group Health Insurance

Group health insurance provides medical coverage to members of a particular organisation or group.

Employers commonly provide group health insurance to employees as a workplace benefit. Coverage may also be extended to an employee’s spouse, children or parents.

Employer-provided coverage may end when the employee leaves the organisation, so having a separate personal policy can provide greater continuity.

Hospitalisation

Hospitalisation refers to admission to a hospital for medically necessary treatment.

Standard in-patient hospitalisation generally requires a continuous stay of at least 24 hours. Listed day-care procedures may be covered even when the hospital stay is shorter.

In-Patient Treatment

In-patient treatment is medical care for which the insured person is formally admitted to a hospital, usually for at least 24 consecutive hours.

Eligible expenses may include:

• Room charges
• ICU charges
• Doctor’s fees
• Nursing expenses
• Medicines
• Diagnostic tests
• Surgery expenses

Coverage remains subject to limits, exclusions and other policy conditions.

Insured, Insurer and Policyholder

These three terms have different meanings:

• Insurer: The insurance company providing the coverage.
• Insured: The person whose medical expenses are covered.
• Policyholder: The person who purchases and owns the policy.

The policyholder and insured person can be the same individual, but this is not always the case.

IRDAI

IRDAI stands for the Insurance Regulatory and Development Authority of India.

It regulates insurance companies and intermediaries operating in India and establishes rules relating to insurance products, policyholder protection and industry practices.

Maternity Cover

Maternity cover provides eligible benefits for pregnancy and childbirth-related expenses.

Depending on the policy, it may include:

• Delivery expenses
• Caesarean-section expenses
• Pre- and post-natal care
• Newborn baby coverage
• Vaccination expenses

Maternity benefits usually have a waiting period, sub-limit and eligibility conditions.

Network Hospital

A network hospital is a hospital that has an arrangement with an insurer or third-party administrator to provide cashless treatment to eligible policyholders.

Choosing a policy with suitable network hospitals in your city can make emergency treatment and claim settlement more convenient.

No-Claim Bonus

A no-claim bonus, also known as a cumulative bonus, rewards policyholders for completing a policy year without making a claim.

Depending on the policy, the insurer may:

• Increase the sum insured without a proportionate increase in premium
• Offer a renewal premium discount
• Provide another specified benefit

The bonus rate, maximum limit and effect of making a future claim vary between policies.

Outpatient Department or OPD

OPD treatment refers to medical consultation or treatment that does not require hospital admission.

OPD expenses may include:

• Doctor consultations
• Diagnostic tests
• Prescription medicines
• Dental treatment
• Eye examinations

Regular health insurance policies may not cover routine OPD expenses unless this benefit is specifically included.

Portability

Health insurance portability allows a policyholder to move from one insurer or policy to another while retaining eligible continuity benefits, subject to applicable rules and underwriting.

Continuity benefits may relate to waiting periods already completed under the previous policy. A portability request should normally be initiated before the existing policy’s renewal date.

Premium

A premium is the amount paid to an insurance company in exchange for health insurance coverage.

Premiums may be paid annually or through other permitted instalment options. The amount can depend on factors such as:

• Age
• Medical history
• Sum insured
• Policy type
• Number of insured members
• Location
• Add-on benefits
• Deductible and co-payment

Pre-Existing Disease

A pre-existing disease is a medical condition diagnosed or treated before purchasing the health insurance policy, according to the definition stated in the policy and applicable regulations.

Applicants should disclose existing illnesses, medicines, previous surgeries and hospitalisation history accurately. Incorrect or incomplete disclosure may affect claim settlement.

Pre- and Post-Hospitalisation Expenses

Pre-hospitalisation expenses are eligible medical expenses incurred before admission to a hospital. Post-hospitalisation expenses are incurred after discharge.

These may include:

• Doctor consultations
• Diagnostic tests
• Prescribed medicines
• Follow-up examinations
• Physiotherapy
• Medical investigations

Coverage is generally available for a specified number of days before and after hospitalisation.

Reimbursement Claim

A reimbursement claim is made when the policyholder pays the hospital bill and later requests payment from the insurer.

This method may be used when treatment is received at a non-network hospital or when cashless approval is unavailable.

The policyholder must submit the required bills, reports and claim documents within the applicable timeline.

Room Rent

Room rent is the amount charged by a hospital for the room or bed occupied by a patient.

Some health insurance policies impose a room-rent limit. Selecting a room above the permitted category may increase out-of-pocket expenses and, in some cases, affect the payment of associated hospital charges.

Sum Insured

The sum insured is the maximum coverage available under a health insurance policy during the policy period, subject to its terms and conditions.

For example, if a policy has a sum insured of ₹10 lakh, the insurer may pay eligible claims up to that limit. Restoration benefits, bonuses, deductibles and sub-limits can affect the actual coverage available.

Waiting Period

A waiting period is the specified time during which certain medical conditions or treatments are not covered, even though the policy is active.

A policy may contain separate waiting periods for:

• Initial illnesses
• Pre-existing diseases
• Listed medical conditions or procedures
• Maternity benefits

Accidental hospitalisation is commonly treated differently from illness-related claims, subject to policy terms.

Important Things to Check Before Buying Health Insurance

Before selecting a health insurance policy, review the following:

• Total sum insured
• Room-rent restrictions
• Co-payment requirements
• Deductible amount
• Waiting periods
• Pre-existing disease coverage
• Network hospitals
• Day-care treatment coverage
• Pre- and post-hospitalisation benefits
• Disease-specific sub-limits
• Policy exclusions
• Restoration benefits
• No-claim bonus conditions
• Claim process
• Lifetime renewability

Do not select a policy based only on its premium. A cheaper plan may contain higher co-payments, stricter room-rent limits or longer waiting periods.

Conclusion

Health insurance terminology does not have to be complicated. Once you understand terms such as sum insured, deductible, co-payment, waiting period, network hospital and cashless hospitalisation, comparing policies becomes much easier.

Always read the complete policy wording before purchasing coverage. Benefits, limits, exclusions and claim requirements can differ significantly between insurers and plans.

Frequently Asked Questions

What is the difference between sum insured and sum assured?

Sum insured is commonly used in health insurance and refers to the maximum amount available for eligible medical expenses. Sum assured is more commonly used in life insurance and generally refers to a fixed benefit payable when the insured event occurs.

What does cashless hospitalisation mean?

Cashless hospitalisation means the insurer settles approved medical expenses directly with a network hospital. The policyholder may still need to pay deductibles, co-payments, excluded expenses and non-medical charges.

What are AYUSH treatments in health insurance?

AYUSH treatments include Ayurveda, Yoga and Naturopathy, Unani, Siddha and Homoeopathy. Coverage may be available when treatment is received at an eligible recognised facility and satisfies the policy conditions.

What is a waiting period in health insurance?

A waiting period is the time during which specified illnesses, treatments or pre-existing conditions are not covered. Different benefits may have different waiting periods.

How does a no-claim bonus work?

A no-claim bonus rewards a policyholder for not making a claim during a policy year. The insurer may increase the sum insured or provide another benefit, subject to the policy’s conditions and maximum limits.

What is the difference between co-payment and deductible?

A deductible is an amount that must be paid before insurance coverage starts paying an eligible claim. A co-payment is the percentage or portion of an approved claim that remains payable by the policyholder.

Can I use cashless treatment at any hospital?

Cashless treatment is generally available only at hospitals included in the insurer’s network. Treatment at a non-network hospital may need to be paid for upfront and claimed later through reimbursement.

Is every medical expense covered by health insurance?

No. Coverage depends on the policy’s sum insured, waiting periods, exclusions, sub-limits, deductibles and co-payment conditions. Always review the policy document to understand which expenses are covered.
