After your discharge (or even during the course of the service), if you are interested in switching to another Health Maintenance Organization (HMO), you have to complete a dedicated form. This form can be completed on the website free of charge, or in any post office - for a cost.
The ability to switch to another HMO is possible on 6 occasions during the year: either on the 1st of January, 1st of March, 1st of May, 1st of July, 1st of September or 1st of November, depending on the date of submission of your request, but not more than twice over a 12 months span. The switch request must be filed up to 45 days prior to the date of transition.
Cancellation of switch request
If you did submit a request to switch to another HMO, and wish to cancel it, you have to submit a cancellation request in the same way you filed your switch request: through the National Insurance Institute's website or at a post office, not later than 45 days prior to the dates of transition.
