Sum Insured Options — Flat vs Graded, Family Definition

Sum insured in a group health insurance policy represents the maximum amount the insurer will pay for covered medical expenses during the policy year for each insured family unit. The sum insured can be structured in two primary ways: Flat Sum Insured, where every employee in the group receives the same sum insured regardless of designation or grade (e.g., Rs. 5 lakh for all employees), and Graded Sum Insured, where the sum insured varies based on employee grade, designation, or salary band (e.g., Rs. 3 lakh for Grade A, Rs. 5 lakh for Grade B, Rs. 10 lakh for Grade C, and Rs. 20 lakh for senior management). The family definition in group health policies determines which family members are covered. The standard definition includes the employee, legally wedded spouse, and up to two dependent children (natural or legally adopted, typically up to age 25). Many employers offer extended family coverage to include dependent parents, parents-in-law, or even siblings with disability. IRDAI mandates that the family definition must be clearly stated in the master policy and the Certificate of Insurance. The choice between flat and graded sum insured, and the breadth of family definition, directly impacts the premium, employee satisfaction, and the company's group health insurance budget.

IRDAI Health Insurance Regulations, 2016, Regulation 4(3): The sum insured and the basis of its determination (flat or graded) must be specified in the master policy schedule. (1) IRDAI Circular on Standardization of Group Health Products (2020) mandates that insurers must clearly define what constitutes a "family" under the policy — the minimum family definition must include the employee and spouse. (2) The Certificate of Insurance must state the specific sum insured applicable to the insured member. (3) For graded structures, the grade-wise sum insured table must be appended to the master policy. (4) IRDAI mandates that any change in the grading structure mid-term must be communicated to all affected members and endorsed in the master policy.

New India Assurance vs. Rolta India Employees (Bombay High Court, 2022) — The Bombay High Court ruled that an employer who promises a specific level of health coverage in the employment contract cannot reduce the sum insured or the scope of family coverage without the employee's consent. Rolta India had reduced the group health sum insured from Rs. 7 lakh to Rs. 4 lakh and removed parent coverage citing cost pressures. The Court directed Rolta India to restore the original coverage or provide the difference through an alternative arrangement, holding that health insurance coverage, when specified in the appointment letter, becomes a contractual obligation.

• Flat SI: Same coverage for all employees — simple but may leave senior staff underinsured. • Graded SI: Coverage varies by grade/designation — aligns with healthcare consumption patterns. • Standard family: Employee + spouse + 2 dependent children (up to age 25). • Parent coverage: Optional add-on costing Rs. 6,000-10,000/parent/year in group policies. • Restoration benefit: SI restored once fully exhausted — critical for lower SI grades. • IRDAI mandates: Family definition, SI structure, and grade table must be in master policy. • Mid-term grade changes require endorsement — claims default to old SI until updated. • Graded SI costs only 2-5% more than flat SI but provides significantly better coverage for senior employees. • Employee-paid voluntary top-ups at group rates are a cost-effective way to enhance coverage. • Always recommend minimum Rs. 5 lakh even for the lowest grade.
