Underwriting in Insurance: Meaning, Process, and IRDAI Guidelines (2026)

Underwriting in insurance is the process that determines whether you get a policy, at what price, and on what terms, and it happens in the background every time someone applies for cover in India. Most applicants only see the outcome: a premium quote, an unexpected loading charge, or a rejection. Very few understand the process behind it.

This guide explains what underwriting is, how it works step by step, what IRDAI’s 2024 Master Circular changed, and crucially, what it means if you are an employer buying group health cover for your team.

What Is Underwriting in Insurance?

Underwriting is the risk evaluation process through which an insurer decides whether to cover an applicant, and on what terms. Think of it like a bank loan credit check: before lending money, a bank assesses your income, credit score, and repayment ability. Insurance underwriting does the same, except instead of default risk, it evaluates your health, lifestyle, and probability of making a claim.

Every underwriting decision results in one of three outcomes:

•  Accept (standard terms): Policy issued at the standard premium with no restrictions.

•  Accept with modification: Policy issued with a loading (higher premium) or a specific exclusion (a condition not covered).

•  Decline: Application rejected because the risk is assessed as too high to underwrite at any viable premium.

Why Underwriting Exists: Underwriting helps keep insurance fair. Without it, only sick people would seek coverage. This would cause premiums to rise sharply. In turn, the whole insurance system could fail. Underwriting keeps the risk pool balanced and premiums fair for everyone.

How the Underwriting Process Works: 5 Steps

Here’s what happens from submitting your insurance application to getting your policy:

1. You fill out the application.
2. The insurance company reviews it.
3. They check your information.
4. They might ask for more details.
5. You receive a decision.
6. If approved, you get your policy.

Lets understand each in detail: 

1. Application & Proposal Form: The insurer gets your completed proposal form. This form includes your health, lifestyle, occupation, and medical history. Accuracy here is critical. Incorrect or incomplete disclosure is the main reason claims get rejected, even years after the policy is issued.

2. Initial Risk Assessment: The underwriter looks at the proposal. They flag areas to review more closely. These include a pre-existing condition, a risky job, an older applicant, or a large insurance amount requested.

3. Medical Examination (if required): For high-sum or high-risk proposals, the insurer may require a medical check-up. Under IRDAI guidelines, the insurer bears the full cost of any medical tests it requests.

4. Underwriting Decision: The underwriter reviews all data. They can either accept the proposal as it is, change it with a loading or exclusion, or decline it. In modern insurance, AI-assisted underwriting tools support this step.

5. Policy Issuance or Communication: If accepted, the policy is issued. If the insurer changes or denies a request, IRDAI’s 2024 rules say they must explain why. They need to do this in writing within 15 days after getting all the needed information. 

Factors Underwriters Consider

Six primary factors shape every underwriting decision in India:

Factor	How It Affects Underwriting
Age	Older applicants carry higher risk, premiums increase with age
Medical History	Pre-existing conditions trigger waiting periods or loading charges
Lifestyle Habits	Smoking, alcohol use, and high BMI are rated as elevated risk
Occupation	High-risk jobs (mining, construction) attract higher premiums
Sum Insured	Higher cover requires more thorough risk assessment
Location	Tier-1 city applicants may face different risk assumptions than Tier-2/3

IRDAI Guidelines on Underwriting: 2024 Master Circular Updates

IRDAI does not underwrite policies, but it sets the rules every underwriter in India must follow. The 2024 Master Circular introduced four significant updates that directly protect policyholders:

IRDAI Update (2024 Master Circular)	What It Means for You
PED Waiting Period	Capped at 3 years (reduced from 4). After 36 months, no condition can be excluded based on pre-existing status.
Moratorium Period	Reduced from 8 years to 5. After 5 continuous years, claims cannot be rejected for non-disclosure unless active fraud is proven.
No Blanket Denial	Insurers cannot categorically reject applicants with serious conditions (cancer, heart disease, HIV). Loading or exclusion allowed; blanket denial is not.
15-Day TAT Mandatory	Insurers must communicate their underwriting decision, accept, modify, or decline, within 15 days of receiving all required documents.

#Also Note:  IRDAI prohibits underwriting discrimination based on religion, caste, race, or gender. Insurers must give a written reason if a proposal is loaded or declined. Curable conditions and those treated by modern medicine include mental illness and genetic disorders. These cannot be permanently excluded.

What Underwriting Means for Employers & HR Teams

When employers buy group health insurance, underwriting is different. It works differently from individual policies. Understanding this difference can save high costs and admin time at renewal.

• Group underwriting is less invasive: Most group health policies underwrite the group as a whole, not each individual. Employees with pre-existing conditions usually get standard coverage in a group plan. They may face loading or exclusion in a personal policy.

• No individual medicals for standard groups: For groups of 7 or more, individual medical exams are usually not needed. The insurer looks at group demographics to assess risk. This includes average age, industry, and occupation. They do not consider each employee’s health history.

• Employer disclosure still matters: Employees don’t need personal medicals. The employer must clearly share details about the business. This includes employee roles and industry risks. The understatement of occupational risk is treated the same as individual non-disclosure.

• Renewals reflect claims experience: At each renewal, the insurer reviews the group’s actual claims history. A high-claims year can lead to a premium increase. Investing in employee wellness and preventive care directly improves your renewal underwriting terms.

How to Improve Your Underwriting Outcome

Disclose everything, accurately: Non-disclosure is the #1 reason claims are rejected. An honest application, even if it ends up in a no-go, is better than a valid claim being denied. IRDAI’s 5-year moratorium protects long-term disclosers from technical rejections. Specifically in retail policies.

For Individuals/Employees

Buy early, before health changes:

Underwriting is most favourable when you are young and healthy. Every year you delay increases the probability of a condition that triggers loading, exclusion, or decline.

For employers

Invest in employee wellness:

A group plan’s renewal premium is tied directly to the claims experience of that year. Lower claims, driven by healthier employees, mean better underwriting terms at renewal.

Conclusion

Understanding underwriting is the first step to making your insurance policy work, for yourself and your team. Whether you are an individual applicant navigating a loading decision, or an HR head buying group cover for the first time, the more you know about how risk is assessed, the better decisions you make.
