What is Group Health Insurance? A Simple Explainer for Indian Employers

Group health insurance is one of the most common employee benefits offered by Indian companies, but the term itself often gets used loosely. This explainer covers what a group policy actually is, how it differs from buying insurance yourself, and what employers and employees should expect.

The Definition

A group health insurance policy is a single master contract issued to an organisation — typically an employer — that provides health cover to a defined group of people. The policyholder is the company; the beneficiaries are the employees (and, in most cases, their spouse, children, and sometimes parents).

Unlike retail health insurance, where each person buys their own policy after medical underwriting, a group policy treats the entire workforce as one risk pool. Premiums are calculated for the group as a whole, not individual by individual.

How It Works in Practice

• The employer purchases the policy from an insurer, typically once a year, for a defined sum insured per employee.
• All eligible employees are automatically covered from the day they meet eligibility (usually the first day of employment).
• Dependants are added based on the plan design — spouse and children are standard; parents and parents-in-law are optional add-ons.
• Claims are filed either cashless at network hospitals or by reimbursement after treatment.
• The policy renews annually, with the premium re-rated based on the previous year's claims experience.

What Group Insurance Typically Covers

• Hospitalisation expenses (room, ICU, surgery, doctor fees)
• Pre-hospitalisation costs (usually 30 days before admission)
• Post-hospitalisation costs (usually 60 to 90 days after discharge)
• Day-care procedures that don't require an overnight stay
• Pre-existing diseases, often from Day 1 with no waiting period
• Maternity benefits (in many but not all plans)

Who Buys Group Health Insurance?

Any registered organisation with a minimum number of employees can buy a group policy. The minimum varies by insurer, but most accept groups of seven or more. Some insurtech platforms accept groups as small as two. Buyers typically include startups, mid-market companies, large enterprises, and increasingly, professional services firms looking to retain talent.

Why Companies Offer It

Three reasons drive most decisions: talent retention, the cost of healthcare for employees, and the post-COVID regulatory expectation that companies provide some form of medical cover. Group cover is also far cheaper per person than retail cover — typically 30 to 50% less for equivalent benefits — because the risk is spread across the whole group.

Frequently Asked Questions

Is group health insurance free for employees?

In most Indian companies, the employer pays the full premium for the employee's base cover. Adding dependants like parents may involve a co-payment by the employee.

Does group health insurance require a medical check-up?

No. Group policies do not require individual medical underwriting. Every employee is covered regardless of pre-existing conditions.

Can a small company buy group health insurance?

Yes. Some insurtech providers offer group policies for companies with as few as two employees.
