Many people assume that having health insurance automatically covers critical illness too. In fact the two are designed for different problems, and more often than not they complement each other rather than replace one another. Here is the difference, clearly.

Health insurance: pays the actual treatment cost

Health insurance looks after the medical bill as it arises — the room, surgery, medication — up to the limits and conditions of the plan. The money goes straight to the cost of treatment. Its strength is giving you access to care without worrying about the hospital bill.

Critical illness cover: a lump sum on diagnosis

Critical illness cover pays a lump sum to the policyholder on diagnosis of a condition listed in the policy, at the stage the policy defines — for example cancer at a specified stage, heart disease, or stroke. That money is yours to use freely; it is not tied to a treatment bill.

Why a lump sum matters

Because the cost of a serious illness is not only the hospital bill. There is the income you lose while recovering, travel, a carer, adapting your home, and treatments health insurance does not cover. The lump sum from critical illness cover acts as replacement income during the period when life has to stop.

What to read closely

  • The list of conditions and the stages covered. Every plan defines these differently: some cover from an early stage, others only severe stages.
  • The waiting period, which for critical illness is usually longer than for ordinary illness.
  • The payment terms — whether the policy pays once and then ends, or pays across several condition groups.

Which should come first?

On a limited budget, the usual thinking is to start with health insurance, because ordinary illness happens far more often, and then add critical illness cover to close the income risk. It depends on the cover you already have, your family history and what concerns you most. There is no single right answer for everyone.

In short

Remember it this way: health insurance looks after the hospital bill; critical illness cover looks after the life that has to keep going while you are seriously ill. Once the role of each is clear, it becomes much easier to set the balance that matches your own risk.
