Pre-Existing Disease (PED) Cover in Group Health Insurance
Pre-existing disease (PED) cover is the part of a group health insurance policy that pays for treatment of medical conditions an employee already had before the policy began — such as diabetes or hypertension. A PED waiting period may apply, but employer group plans can often reduce or waive it.
In a retail policy a pre-existing condition can sit behind a 24–48 month waiting period. A group plan pools risk across the workforce, so insurers often reduce or fully waive it — giving employees day-one cover for conditions like diabetes or hypertension, with no individual medical test to enrol.
How PED cover works in an employer plan
A pre-existing disease is any condition an employee was diagnosed with, treated for, or had symptoms of before the policy started — the industry benchmark is the 48 months preceding the start date. Diabetes, hypertension, thyroid disorders and asthma are the most common examples.
In a retail (individual) policy, these conditions usually sit behind a PED waiting period of 24 to 48 months — claims tied to the condition are excluded until that clock runs out. Group health insurance works differently. Because the policy pools risk across an entire workforce, the insurer is far more willing to reduce that waiting period, and many corporate plans waive it altogether so cover applies from day one.
Group plans also typically skip individual medical check-ups at enrolment. That means an employee with a known condition is brought into cover without a pre-policy test, and — where the PED waiting period is waived — can claim for that condition immediately.
A worked example
How a waived PED waiting period changes the outcome of a real claim.
Set-up
A 180-person company buys a group plan with a ₹5,00,000 sum insured per employee. The employer negotiates a day-one PED waiver, so no waiting period applies.
The employee
Priya, a product manager, was diagnosed with Type 2 diabetes two years before joining — clearly a pre-existing condition.
The event
Eight weeks into cover, Priya is hospitalised for a diabetes-related complication. The bill comes to ₹1,80,000.
The outcome
Because the PED waiting period was waived, the claim is admissible from day one. She is treated cashless at a network hospital and pays nothing upfront; the insurer settles ₹1,80,000 directly, subject to policy terms.
Figures are illustrative. Actual admissibility, sub-limits and settlement depend on the specific policy schedule and insurer terms.
Why PED cover matters for employers
A meaningful share of any workforce lives with a chronic, pre-existing condition. If your plan makes those employees wait years before they can claim for it, the benefit looks generous on paper but fails the people who need it most — and that gap is quickly felt.
Negotiating a reduced or waived PED waiting period turns the policy into cover employees can actually rely on from their first day. That directly supports hiring (candidates with existing conditions are not penalised), retention, and the credibility of the benefit you are paying for.
It is also a lever you control at purchase. PED terms are set in the group policy schedule, so getting them right up front — rather than discovering an exclusion at claim time — is one of the highest-value decisions an HR or finance leader makes when buying group cover.
How Onsurity handles pre-existing disease cover
Onsurity group health plans extend cover to a wide range of pre-existing conditions — including diabetes, hypertension, thyroid issues and asthma. Depending on your team size and average age, a short PED waiting period may apply, and day-one cover options are available so eligible teams are protected from the start.
When a pre-existing condition needs treatment, employees can go cashless at 10,000+ network hospitals across India — no upfront payment where the claim is admissible. The Good Doctors claims concierge, a team of real doctors, guides members from hospital admission through to settlement.
Employers manage the whole programme — onboarding, dependents, renewals and claim visibility — from the TeamSure dashboard, with no individual medical check-ups required to enrol. It keeps PED cover simple to set up and simple to use.
Frequently asked questions
What counts as a pre-existing disease in group health insurance?
A pre-existing disease (PED) is any condition, ailment, or injury that an employee was diagnosed with, treated for, or showed signs of within 48 months before the policy start date — commonly diabetes, hypertension, thyroid disorders, or asthma.
Is there a waiting period for pre-existing diseases in a group plan?
Retail policies typically impose a 24 to 48 month PED waiting period. Group employer plans can negotiate this down and, for many corporate policies, waive it entirely so cover applies from day one.
Can the PED waiting period be waived for employees?
Yes. Because a group policy pools risk across an entire workforce, insurers frequently agree to reduce or fully waive the PED waiting period, meaning an employee with a pre-existing condition is covered from the first day.
Do employees need a medical test to get PED cover?
In most group health plans no individual medical check-up is required for enrolment. Cover, including for pre-existing conditions, is extended on a group basis without pre-policy tests.
Are pre-existing conditions covered for employee dependents too?
When a plan includes dependents such as a spouse, children, or parents, PED terms generally extend to them on the same basis as the employee, subject to the policy schedule.
