All joint health insurance policies will cover the cost of treatment in a private hospital where an overnight stay is required (inpatient). This could be to recover from a major operation or a treatment which is provided over the course of several days.
Most, but not all, joint health insurance policies will cover the costs of you occupying a hospital bed for just a day, with no overnight stay required. It could be that you’ve undergone minor surgery for instance and need a bed just for a few hours of observations.
Outpatient treatment is any test, procedures or consultations which don’t require a hospital bed. When configuring your policy you can opt to have no outpatient treatment, cover up to a certain annual cash value or full outpatient insurance.
