Three months ago, a friend resigned from her IT company in Bangalore to join a startup. She was excited about the new role, the higher salary, the equity. What she had not thought about: her company health insurance ended on her last working day.

Two weeks into the new job, her daughter needed an emergency appendectomy. The new employer's insurance had not kicked in yet. The hospital bill was Rs 2.8 lakh. She paid it all from her savings because she assumed the gap would not matter.

This happens to thousands of people in India every year. Corporate health insurance feels like it is yours, but it belongs to your employer. The moment you resign, retire, or get laid off, it is gone. And if you wait to buy individual health insurance only after you leave, pre-existing conditions get a 2 to 4 year waiting period.

The smart move is to buy your own policy while you still have corporate cover, so there is zero gap.

Why corporate health insurance is not enough even while you work

Most employer plans cover Rs 3 to Rs 5 lakh. That sounds decent until you need a major surgery, cancer treatment, or a long ICU stay. A single bypass surgery in a metro hospital costs Rs 3.5 to Rs 6 lakh. Cancer treatment can run Rs 10 to Rs 20 lakh over a year. Your Rs 5 lakh corporate policy will run out fast.

Corporate plans often have co-payment clauses for family members, limited room rent coverage, and restrictions on pre and post hospitalization expenses. And here is the part most employees miss: the policy covers only your immediate family as defined by your employer. If you want to cover your parents, most corporate plans either exclude them or charge a heavy extra premium.

When to buy individual health insurance

Right now. Seriously. If you are reading this and only have employer health insurance, start comparing individual plans this week. Here is why timing matters:

The younger you are when you buy, the lower your premium for life. A 28-year-old buying a Rs 10 lakh plan pays Rs 6,000 to Rs 8,000 per year. The same plan at 40 costs Rs 14,000 to Rs 18,000. At 50, it jumps to Rs 25,000 or more.

Pre-existing diseases have waiting periods of 2 to 4 years. If you buy now while healthy, by the time something develops, the waiting period is already done. If you wait until you have a condition, you are stuck paying premiums for years before the insurer covers that condition.

You can port your policy later if you find a better deal, but waiting periods restart partially during porting. Starting early eliminates this problem.

Health insurance portability: your right under IRDAI rules

If you already have a personal health insurance plan and want to switch insurers, IRDAI allows portability. This means your accumulated no-claim bonus and time served toward waiting periods transfer to the new insurer.

The port health insurance India process works like this: apply to the new insurer at least 45 days before your existing policy renewal date. The new insurer reviews your claim history and medical records. If approved, your waiting period credits carry over.

This is useful if you bought a plan years ago and now see better options. You do not lose your waiting period benefits when switching.

If you freelance, run a small business, or work in the gig economy, you have no employer safety net at all. The best health insurance for self employed individuals is a personal floater plan with at least Rs 10 lakh coverage.

A simple action plan

If you are currently employed with corporate health insurance, buy an individual plan now with Rs 10 to Rs 15 lakh cover. This runs parallel to your employer plan and kicks in fully the day you leave.

If you are between jobs, buy immediately. Every day without cover is a financial risk. You can get an online health policy purchase done in 20 minutes with instant policy issuance.

If you are self employed, get a mediclaim policy with comprehensive coverage and zero co-payment. Consider adding a personal accident cover as well, since you do not have employer disability benefits.

The cost of being uninsured for even one month can exceed what you would pay in premiums for an entire decade. Do not gamble with your family's financial security because the paperwork feels like a task for tomorrow.
