## 💡 The "No-Brainer" Checklist for 2026
Even if you pick a highly-trusted company, a policy is only as good as its fine print. Ensure the specific plan you choose features:
* **No Room Rent Capping:** Avoid plans that limit your room rent to 1% of the sum insured. Look for "No Limit" private AC room features.
* **Zero Co-payment:** Ensure you don’t have to pay a fixed percentage (e.g., 10% or 20%) of the bill out of your own pocket.
* **No Disease-wise Sub-limits:** Ensure there isn't a hidden cap on common surgeries (like cataracts or joint replacements).
* **Speedy Cashless Mandates:** Per 2026 IRDAI guidelines, look for insurers seamlessly honoring the **1-hour cashless pre-authorization** and 3-hour discharge clearance window.
Are you looking to buy this policy primarily for yourself, an entire family (floater), or senior citizen parents? Knowing this can help narrow down the exact plan variant that fits best.
