Health · Nao Explains

Why doesn't my health plan cover everything on day one? (It's not being rude.)

You buy a health plan on Monday. By Tuesday you're hoping it covers everything, starting right now. Insurance needs a warm-up lap first, called the waiting period: the time between your start date and the day a particular benefit begins.

Why have one at all? It keeps premiums fair. If people could buy cover the day they need it and cancel the day after, everyone else would pay for it. A waiting period means the plan works for people who buy before they need it, which is how insurance stays affordable.

What it looks like in practice

On Pacific Cross health plans, the general waiting period is 30 days, and maternity benefits begin after 12 months. On Liberty, cancer (oncology) cover starts at 70% after 90 days and reaches 100% after 180 days.

What about conditions I already have?

These are called pre-existing conditions. They're covered only if you declare them on the application and the insurer accepts them. Declaring isn't a trap: it's how you make sure a claim is paid later. If you're unsure whether something counts, ask before you apply. A licensed member of our team checks every application before it goes to the insurer.

The easy win: if you're planning a family or a move, start your plan early. The waiting period runs while life carries on.

It is the time between your policy start date and the day a particular benefit begins. Each benefit can have its own waiting period.

How long are waiting periods?

It depends on the plan and the benefit. For example, Pacific Cross health plans have a 30-day general waiting period, and maternity benefits begin after 12 months. On Liberty, cancer care is paid at 70% after 90 days and at 100% after 180 days.

Are pre-existing conditions covered?

Only if you declare them on the application and the insurer accepts them. If you're unsure whether something counts, ask before you apply.

How do I keep a waiting period from catching me out?

Start early, before you need the cover, for example before you plan a family or a move.
