Attach a yellow sticker to every doctor's note or other document that you provide to CM. Sticky notes? You can request new ones here.
From April 1, 2022, your new yellow stickers will have 120 as the health insurance number .
That number will replace the number of your former CM region. CM Flanders has been a legal entity since January 1, 2022, with the result that each region receives the same health insurance fund number. And that is 120.
Do you still have old stickers with an old health insurance number? No problem, you can continue to use them on your documents.
