Uncapped coverage: Is your health policy really ‘unlimited’?

Summary

Unlimited health plans from Niva Bupa, Care, ICICI Lombard and HDFC ERGO work in different ways, and some retain caps or conditions despite the label. What exactly is unlimited, and what conditions continue to apply when a large claim arrives?

How much health insurance is enough when medical costs outpace incomes? While a ₹10 lakh cover seems adequate today, prolonged ICU stays, complex surgeries, or treatments for rare diseases can easily exceed standard limits.

To address this, insurers now offer unlimited health insurance plans. Rather than capping the base sum insured (SI), these policies pay eligible hospital bills, whether they are ₹8 lakh or ₹80 lakh. However, not every unlimited health plan works this way—some use uncapped base limits, while others rely on infinite renewal bonuses or unlimited restoration features.

Here is how four major offerings compare:

Niva Bupa ReAssure 3.0: unlimited cover, but check the room category

Niva Bupa ReAssure 3.0 has four variants—Classic, Select, Elite and Black. Customers can choose a ₹5 lakh, ₹10 lakh or unlimited sum insured.

“You can buy any variant, either having ‘unlimited’ sum insured or a base cover of ₹5 lakh or ₹10 lakh. A higher sum insured is not possible. It has to be either ₹5 lakh, ₹10 lakh or unlimited,” said Ashish Kumar, founder, Sri Shani Financial Services.

According to data from insurance corporate agent Nyvo Insurance Services, the Black variant with ₹10 lakh cover and the Booster+ no-claim bonus rider costs ₹17,356 for a 30-year-old male from Mumbai. The unlimited option costs ₹23,836, about 37% more.

Booster+ adds 100% of the base SI for every claim-free year, up to 10 times the base SI in limited coverage options. Thus, on a ₹10 lakh policy, paying three annual premiums builds the cover to ₹30 lakh at the beginning of the third policy year ( ₹10 lakh base SI + ₹20 lakh booster+). If you then make an ₹18 lakh claim during the third year, ₹10 lakh comes from the base SI and ₹8 lakh from the bonus, leaving ₹12 lakh in the booster+ balance. At the beginning of the fourth year, cover becomes ₹32 lakh ( ₹10 lakh base SI + ₹12 lakh remaining booster+ + ₹10 lakh fresh booster+), not ₹40 lakh.

However, accumulated cover does not increase every benefit. Modern treatments and sub-limits, such as air ambulance cover, may remain linked to the base SI.

With unlimited SI, modern treatment is capped at ₹1 lakh under the Classic and Select plans. Room eligibility also varies: general ward for Classic, twin-sharing for Select, all rooms except deluxe and suite for Elite, and all room categories for Black, Kumar said.

“Even with unlimited SI, non-payable items like gloves, masks, PPE kits, syringes and nebulizer kits will not be covered unless the customer buys the Safeguard+ add-on,” he added.

This makes the choice between an unlimited variant and a high base SI with accumulated bonus less straightforward than it appears.
